Answer:
A I'm pretty sure
Step-by-step explanation:
To find the expected value, we need to multiply each possible outcome by its probability and add up the results.The probability of drawing a ball with $1 is 5/10 = 0.5.
The probability of drawing a ball with $2 is 2/10 = 0.2.
The probability of drawing a ball with $30 is 3/10 = 0.3.
The expected value is:
(0.5 * 1) + (0.2 * 2) + (0.3 * 30) = 0.5 + 0.4 + 9 = 9.9
However, the person paid $10 to play, so we need to subtract that from the expected value:9.9 - 10 = -0.1
Therefore, the expected value of this game is -$0.10. Answer choice (A) is correct.

The solution to the word problems are:
1) ∠JML = 63°
2) The center of the circle is (4, -4) and Radius = 4
3) The required measurement of the table cloth should be:
48 in x 36 in
4) The correct option of the similar triangles is:
UY/UV = UZ/ZW
How to solve algebraic word problems?1) The angle subtended by an arc at the Centre is twice the angle subtended at the circumference . More simply, the angle at the centre is double the angle at the circumference. Thus:
∠JML = 126/2 = 63°
2) The general formula for equation of a circle is expressed as:
(x - h)² + (y - k)² = r²
where:
(h, k) is the coordinate of the center of the circle
r is the radius
We are given the circle equation as:
(x + 4)² + (y - 4)² = 16
This can be rewritten as:
(x + 4)² + (y - 4)² = 4²
Thus:
Coordinates of center = (4, -4)
Radius = 4
3) The required measurement of the table cloth should be:
48 in x 36 in
4) Since both triangles are similar, then it means ratio of corresponding sides will be equal and as such:
UY/UV = UZ/ZW

Let S be the universal set, where: S={1, 2, 3,…, 18, 19, 20}
Let sets A and B be subsets of S, where:
n(A ∪ B ∪ C) = 16
n(A u B u C) = 2.
How to solve for the setTo find the number of elements in the set ( A cup B cup C), we need to find the union of the sets A, B, and C. This can be done by combining all the elements in A, B, and C, and then removing any duplicates.
So, (A ∪ B ∪ C) = {1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 20}
Therefore, n(A ∪ B ∪ C) = 16.
To find the number of elements in the set ( A ∩ B ∩ C), we need to find the intersection of the sets A, B, and C. This can be done by finding the elements that are common to all three sets.
So, (A ∩ B ∩ C) = {8, 20}
Therefore, n(A u B u C) = 2.

On Monday,1 7/8 inches of rain fell. On Tuesday,it rained 1/4 inch. What was the total rainfall for the two days?
Answer:
2.125 inches
Step-by-step explanation:
We Know
On Monday, 1 7/8 inches of rain fell. On Tuesday, it rained 1/4 inch.
1 7/8 = 15/8
What was the total rainfall for the two days?
We Take
15/8 + 1/4 = 15/8 + 2/8 = 17/8 inches of rainfall
17/8 = 2.125
So, the total rainfall for the two days is 2.125 inches.
Answer:
2 1/8 inches
Step-by-step explanation:
You need to add the two amounts of rainfall together to get your answer, which is 1 7/8 + 1/4. To add these fractions, make the fractions equivalent. To find equivalent fractions, we multiply the numerator and the denominator by the same number.
Since 1/4 can be 2/8, you can now add 1 7/8 + 2/8. This equals 2 1/8.
Therefore, the total rainfall for the two days was 2 and 1/8 inches.

Which type of function best models the data in each table? Use differences or ratios. X-0, 1, 2, 3, 4
Y-0,1.5,6,13.5,24
Answer:
To determine the type of function that best models the data in the table, we can observe the differences or ratios between successive values of y.
Using differences:
The first differences between successive values of y are:
1.5 - 0 = 1.5
6 - 1.5 = 4.5
13.5 - 6 = 7.5
24 - 13.5 = 10.5
The second differences between successive values of y are:
4.5 - 1.5 = 3
7.5 - 4.5 = 3
10.5 - 7.5 = 3
Since the second differences are constant, the function that best models the data is a quadratic function.
Using ratios:
The ratios between successive values of y are:
1.5/0 = undefined
6/1.5 = 4
13.5/6 = 2.25
24/13.5 ≈ 1.78
Since the ratios are not constant, the function that best models the data is not an exponential function.
Therefore, the type of function that best models the data in the table is a quadratic function. We can try to find a quadratic function of the form y = ax^2 + bx + c that passes through the given points. Using the first three points, we get the system of equations:
a(0)^2 + b(0) + c = 0
a(1)^2 + b(1) + c = 1.5
a(2)^2 + b(2) + c = 6
Solving this system of equations, we get:
a = 3/2
b = 0
c = 0
Therefore, the quadratic function that best models the data is y = (3/2)x^2.
Triangle ABC ~ triangle DEF. Use the image to answer the question. a triangle ABC with side AB labeled 11, side CA labeled 7.6 and side BC labeled 7.9 and a second triangle DEF with side DE labeled 4.4 Determine the measurement of EF. EF = 3.47 EF = 3.16 EF = 1.39 EF = 1.1
Answer:
FD = 3.16
Step-by-step explanation:
To determine the length of FD, we can use the property of similar triangles that corresponding sides are in proportion to each other. That is,
AB/DE = BC/EF = CA/FD
We are given the lengths of AB, CA, and BC in triangle ABC, and we know that triangle ABC is similar to triangle DEF. We can use the first two sides to find the third side of triangle DEF as follows:
AB/DE = 11/DE = 7.9/EF
=> EF = (DE * 7.9) / 11
Next, we can use the third proportionality to find FD:
CA/FD = 7.6/FD = 11/EF
=> FD = (11 * 7.6) / EF
=> FD = (11 * 7.6) / ((DE * 7.9) / 11)
=> FD = (11^2 * 7.6) / (DE * 7.9)
Now, we just need to substitute the given values and solve for FD:
FD = (11^2 * 7.6) / (4.4 * 7.9)
FD = 3.16
Therefore, the length of FD is 3.16.

The point (2, 7) belongs to the solution region of the system of inequalities.
What is inequalities?
In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).
The system of inequalities given is:
y > 1.5x + 4
y > -x + 6
One point that belongs to the solution region of this system of inequalities is (2, 7).
To check if this point satisfies the system of inequalities, we can substitute the values of x and y into each inequality:
For the first inequality, y > 1.5x + 4, we have:
7 > 1.5(2) + 4
7 > 7
This is true, so the point (2, 7) satisfies the first inequality.
For the second inequality, y > -x + 6, we have:
7 > -(2) + 6
7 > 4
This is also true, so point (2, 7) satisfies the second inequality.
Therefore, points (2, 7) belong to the solution region of the system of inequalities.

The graph and table each show a proportional relationship between the number of miles traveled and the
advertised number of gallons of gas used for the two car models, A and B, respectively. Based on the
graph and table, car A can travel how many times the distance car B can travel when both cars use
1 gallon of gas? Write your answer as a decimal.
Enter your answer in the box
1.25
To answer this question, we need to compare the ratios of miles traveled to gallons of gas used for car A and car B when they both use 1 gallon of gas.
For car A, we can see from the graph that 50 miles are traveled for every 2 gallons of gas used, or in other words, 25 miles are traveled for every 1 gallon of gas used. Therefore, car A can travel 25 times the distance for 1 gallon of gas.
For car B, we can see from the table that 40 miles are traveled for every 2 gallons of gas used, or in other words, 20 miles are traveled for every 1 gallon of gas used. Therefore, car B can travel 20 times the distance for 1 gallon of gas.
To compare the two ratios, we can divide the ratio of miles traveled to gallons of gas used for car A by the ratio for car B:
25/20 = 1.25
Therefore, car A can travel 1.25 times the distance car B can travel when both cars use 1 gallon of gas.

D The combined expenses in Years 3 and 4 were $300,000 more than the combined income in Years 3 and 4.
Correct option is D. the combined expenses are $300,000 more than the combined income.
What is the bar chart?In business, economics, statistics, and science, bar charts are frequently used to display and compare data. When dealing with data that can be divided into discrete categories, like nominal or ordinal data, they are especially helpful.
According to the Income and expenses graph;
We can verify each options one by one.
A. Expenses have increased $200,000 each year over the last 5 years:
If we see the graph for expenses in each year that is increased by $100,000 not the $200,000 over the last 5 years.
So, the option is wrong.
B. The income in Year 5 was twice the income in Year 1:
Income in year 1 = $600,000
Income in year 5 = $900,000
We can see here, income is not just double.
So, the option is wrong.
C. The sum of all expenses in Years 1, 2, and 3 was the same as the sum of all income in those years:
combined income in Years 1, 2, and 3 = $600,000 + $600,000 + $400,000 = $1600,000
combined expenses in Years 1, 2, and 3 = $400,000 + $500,000 + $600,000 = $1500,000
Both are not equal.
So, the option is wrong.
D. The total amount expenses in Years 3 and 4 were $300,000 more than the total amount income in Years 3 and 4:
combined expenses in Years 3 and 4 = $600,000 + $700,000 = $13,00,000
combined income in Years 3 and 4 = $400,000 + $600,000 = $10,00,000
We can see here the combined expenses are $300,000 more than the combined income.
So, the option is correct.

What is statistics?
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.
a. To find the percentage of people with a systolic blood pressure above 130, we need to calculate the area under the standard normal curve to the right of the z-score corresponding to a systolic blood pressure of 130.
z = (130 - 120) / 8 = 1.25
Using a standard normal distribution table or calculator, we find that the area to the right of z = 1.25 is 0.1056 or 10.56%. Therefore, approximately 10.56% of people have a systolic blood pressure above 130.
b. To find the percentage of people with a systolic blood pressure between 120 and 130, we need to calculate the area under the standard normal curve between the z-scores corresponding to systolic blood pressures of 120 and 130.
z1 = (120 - 120) / 8 = 0
z2 = (130 - 120) / 8 = 1.25
Using a standard normal distribution table or calculator, we find that the area between z = 0 and z = 1.25 is 0.3944 or 39.44%. Therefore, approximately 39.44% of people have a systolic blood pressure between 120 and 130.
c. To find the range of systolic blood pressures for the middle 60% of the population, we need to find the z-scores corresponding to the 20th and 80th percentiles of the standard normal distribution, which are -0.84 and 0.84, respectively.
The corresponding systolic blood pressures are:
lower limit: z1 * 8 + 120 = 113.68
upper limit: z2 * 8 + 120 = 130
Therefore, the range of systolic blood pressures for the middle 60% of the population is approximately 113.68 to 130.
d. To find the systolic blood pressure that qualifies a person for additional monitoring if they are in the top 15% of the population, we need to find the z-score corresponding to the 85th percentile of the standard normal distribution.
Using a standard normal distribution table or calculator, we find that the z-score corresponding to the 85th percentile is 1.04.
The corresponding systolic blood pressure is:
systolic blood pressure = z * 8 + 120 = 128.32
Therefore, a systolic blood pressure of 128.32 or higher would qualify a person for additional monitoring if they are in the top 15% of the population.

A bus traveled on a level road for 3 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 2 hours. Find the average speed on the level road if the entire trip was 290 miles.
Answer:
Let's call the average speed on the winding road "x". Then, the average speed on the level road is "x + 20".
We know that the bus traveled on the winding road for 2 hours, so the distance traveled on the winding road is:
distance = rate × time = x × 2 = 2x
We also know that the bus traveled on the level road for 3 hours at an average speed of "x + 20", so the distance traveled on the level road is:
distance = rate × time = (x + 20) × 3 = 3x + 60
The total distance traveled is 290 miles, so we can write:
2x + 3x + 60 = 290
Combining like terms and solving for x, we get:
5x + 60 = 290
5x = 230
x = 46
Therefore, the average speed on the winding road is 46 mph, and the average speed on the level road is:
x + 20 = 46 + 20 = 66 mph.
Question
Two people rented a car from the same agency. The first person drove 1010 miles and paid $232.30 for mileage. The
second person drove 765 miles and paid $175.95 for mileage. What is the agency's fee per mile?
The fee of agency's per mile is $0.23 or 23 cents.
Let the fee charged by agency for per mile drive be $x.
It is given that first people drove 1010 miles and charged $232.30 by agency.
So the equation for first person is,
1010x + y = 232.30........... (i), where y is fixed charge by the agency if it is there.
Also given that second person drove 765 miles and paid $175.95 to agency.
So the equation for the second person is,
765x + y = 175.95 ............. (ii)
Subtracting equation (ii) from equation (i) we get,
1010x + y - 765x - y = 232.30 - 175.95
245x = 56.35
x = 0.23
Hence the fee of agency's per mile is $0.23 or 23 cents.

uniform
Answer:1
Step-by-step explanation:
Weekly revenue, in dollars, at Pizza Garden can be modeled by the equation y = 1000 + 18x, whe
sold. The pizzeria's weekly expenses, in dollars, can be modeled by the equation y = 1700 + 13x.
How many pizzas must be sold at Pizza Garden in a week for the pizzeria to break even?
Note: The phrase break even refers to the value where the two functions are equivalent. When x is less than the break-even value, the pizzeria has
revenue below expenses, and so it loses money. When x is above the break-even value, the pizzeria has revenue above expenses, and so it makes a
profit.
O 140
O 540
O 3500
O 3520
Answer:
To find the break-even point, we need to set the revenue equal to the expenses and solve for x:
1000 + 18x = 1700 + 13x
5x = 700
x = 140
Therefore, Pizza Garden needs to sell 140 pizzas in a week to break even. So the answer is 140.
Expand (x+2y) in ascending powers of x.
Hence, x + 2y is the expansion of (x+2y) in ascending powers of x as that every number raised to the power of zero equals 1.
what is exponents ?Exponents, usually referred to as powers and indices, are a type of mathematical operation that requires increasing a base number to a specific exponent. You can multiply the minimum amount by itself a given number of times using the exponent. For instance, the number 2 raised toward the power of 3 (printed as 23) is equivalent to 2 x 2 x 2, which is 8. Exponents are frequently employed in scientific notation, algebra, and other areas of mathematics to express extremely big or extremely small integers.
given
The distributive property of multiplication is used to multiply out the expression when expanding (x+2y) in ascending powers of x.
[tex](x + 2y) = x + 2yx^0[/tex]
By remembering that every number raised to the power of zero equals 1, we may simplify the second term. We thus have:
(x + 2y) = x + 2y(1) (1)
When we multiply the expression, we get:
(x + 2y) = x + 2y
Hence, x + 2y is the expansion of (x+2y) in ascending powers of x as that every number raised to the power of zero equals 1.
