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.

The percentage of students still writing the test is

23.75%

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign( %).

For example if there are 80 student in a class and 20 are boys, the percentage of boys in the class is ; 20/80 × 100 = 25%

The total number of students that finished the test before 1.75hours = 17+12+22 = 61

The number of students left in the class = 80-61

= 19

Therefore percentage of of the student still taking the test after 1.75 = 19/80 × 100

the absolute change in the percentage increase amounts from Paula's investments is 74.5%.

What is the percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. The percentage refers to one in a hundred. The % sign is used to denote it.

The absolute change in the percentage increase amounts is the difference between the two percentages.

Absolute change = |87.4% - 12.9%| = |74.5%| = 74.5%

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.

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.

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.

Correct option is D. the combined expenses are $300,000 more than the combined income.

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.

The height of the object at any given time t is given by the function h(t) = -t^2 + 6t + 10. To find the maximum height, we need to find the vertex of the parabola described by this function.

The vertex of a parabola in the form y = ax^2 + bx + c is given by the formula (-b/2a, f(-b/2a)), where f(-b/2a) is the y-coordinate of the vertex.

In this case, a = -1, b = 6, and c = 10, so we have:

t = -b/2a = -6/(-2) = 3

To find the maximum height, we need to evaluate h(3):

h(3) = -(3)^2 + 6(3) + 10 = 9 + 18 + 10 = 37

Therefore, the maximum height of the object is 37 units, which occurs when t = 3 seconds.

About 9.1% of people have a systolic blood pressure above 130.about 34.1% of people have a systolic blood pressure between 120 and 130.

A number can be expressed in fractions of 100 using a percentage. When expressing it, the notation %, which stands for "per hundred," is frequently used. 50%, for instance, equals 50/100, or the percentage 1/2.

a. To find the percentage of people with a systolic blood pressure above 130, we need to find the area under the normal curve to the right of 130. Using a standard normal distribution table or a calculator, we can find that this area is approximately 9.1%. Therefore, about 9.1% 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 find the area under the normal curve between 120 and 130. Using a standard normal distribution table or a calculator, we can find that this area is approximately 34.1%. Therefore, about 34.1% 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 two values of systolic blood pressure that separate the centre 60% of the normal curve's area under the curve. Using a standard normal distribution table or a calculator, we can find that these values are approximately 111.4 and 128.6. Therefore, the range of systolic blood pressures for the middle 60% of the population is approximately 111.4 to 128.6.

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 value of systolic blood pressure that separates the top 15% of the area under the normal curve from the rest. Using a standard normal distribution table or a calculator, we can find that this value is approximately 131.4.

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.
