The bar model that represents the number of cousins that Sawyer has, given the cousins Hazel has is the fourth bar model.

The letter " c " is meant to represent the number of cousins that Sawyer has, in relation to those that Hazel has. This means that bar models A and C are out because they represent the cousins as B.

The question shows that Hazel has twice the number of cousins that Sawyer has. This means that if Sawyer's cousins are represented as " c " then Hazel would be 2 c. This is shown in the last bar model so this is the correct bar model.

Using the Intersecting secants theorem, the length of JK in the given diagram is 17

From the question, we are to determine the length of JK in the given diagram.

The diagram shows a circle with intersecting secants.

From the Intersecting secants theorem which states that "if two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment".

Then,

We can write that

JK × KL = NM × ML

From the given diagram,

KL = 14

NM = 14

ML = 17

Substituting the values

JK × 14 = 14 × 17

JK = (14 × 17) / 14

JK = 17

Hence, the length of JK is 17

The first car consumed 15 gallons of gas

The second car consumed 30 gallons of gas during the week

Let's denote the number of gallons consumed by the first car as x, and the number of gallons consumed by the second car as y.

We know that the total gas consumption is 45 gallons, so:

x + y = 45

We also know that the total distance traveled is 1725 miles, and that the fuel efficiency (miles per gallon) of the first car is 35, and of the second car is 40. Using this information, we can write another equation:

35x + 40y = 1725

We now have two equations with two unknowns, which we can solve simultaneously to find x and y.

Multiplying the first equation by 35, we get:

35x + 35y = 1575

Subtracting this equation from the second equation, we get:

5y = 150

y = 30

Substituting y = 30 into the first equation, we get:

x + 30 = 45

x = 15

Therefore, the first car consumed 15 gallons of gas, and the second car consumed 30 gallons of gas during the week.

he two numbers that multiply to -35 and add to get -18 are -5 and 3.

To see why, you can use the factoring method. First, find two numbers that multiply to give you -35. The factors of -35 are -1, 1, -5, and 5. So, the two numbers that multiply to -35 are either -5 and 7 or 5 and -7.

Next, find which pair of numbers adds up to -18. It's clear that 5 and -7 add up to -2, so they don't work. However, if we choose -5 and 3, we get:

-5 + 3 = -2

So, -5 and 3 are the two numbers that multiply to -35 and add to -18.

The length of the missing base is approximately 6.67 cm.

By applying the formula for the area of a trapezoid, we will be able to solve for the missing base.

Recall that the formula for the area of a trapezoid is:

A = [tex]\frac{1}{2} * h * (b_{1} + b_{2})[/tex]

where

A = area

h = height

b₁ and b₂ are the lengths of the parallel bases.

From the question, we are given:

A = 64 m²

h = 12 cm

b₁ = 4 cm.

Plug these values into the formula above to solve the missing base

64 = [tex]\frac{1}{2} * 12 * (4+ b_{2})[/tex]

Multiplying both sides by 2:

128 = 12(4 + b₂)

Simplifying:

128 = 48 + 12b₂

80 = 12b₂

b₂ = 80/12 = 20/3

b₂ = 6.67

The number of dahlias should the florist expect to sell on a day with 120 customers is 90 bouquets.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Sold bouquets=15

Total customers=120

Now,

In this case, the number of successful outcomes is 15, and the number of total outcomes is 20.

So the experimental probability is:

2015​=43​

To find the expected number of bouquets of dahlias to sell on a day with 120 customers, you need to multiply the experimental probability by the number of customers.

In this case, you need to multiply 3/4 by 120:

The reflection line  that maps polygon ABCDE to polygon A' B' C' D' E' is the y-axis.

The image is reflected through a line known as a reflection line. A pattern is said to mirror another pattern, and then every point in the pattern is equidistant from every corresponding point in the other pattern. The reflected image must be the same shape and size, but the image is in the opposite direction.

In order to determine the line of reflection that maps  polygon ABCDE to polygon A' B' C' D' E', we must find a symmetrical line  equidistant from each corresponding pair of points. If you project the image across the x-axis, vertex A (-1, -4) is mapped to A' (13, -4) and vertex E (1, -6) is mapped to E'. (11, 6). Therefore, the reflection line must be the x-axis.

If we map the image to the cross x=6, vertex A (-1, -4) would correspond to A' (13, -4) and vertex E (1, -6) would correspond to E' (3, 6). ). Therefore, the reflection line cannot be x=6.

If we project the pattern perpendicular to y=-3, the point A (-1, -4) is opposite to the point A' (-7, -4) and the vertex E (1, -6)  to  the point E . (7, 6). Therefore, the reflection line  cannot be y=-3.

 If you project the image across the y-axis, point A (-1, -4) is mapped to point A' (-13, -4) and  vertex E (1, -6) is mapped to E. (-11 , 6). Therefore, the reflection line  must be the y-axis.

So, the length of WZ is 24 in kite WXYZ with diagonals WY and XZ.

A triangle is a closed, two-dimensional geometric shape that is formed by three line segments, called sides, that intersect at three points, called vertices. Triangles are one of the most basic shapes in geometry and are studied extensively in mathematics. The properties of triangles depend on the length of their sides and the size of their angles. Triangles can be classified based on the length of their sides as equilateral, isosceles, or scalene, and based on the size of their angles as acute, right, or obtuse. In an equilateral triangle, all three sides are of equal length. In an isosceles triangle, two sides are of equal length, while the third side is of a different length. In a scalene triangle, all three sides are of different lengths.

Here,

Since WXYZ is a kite, we know that its diagonals, WY and XZ, intersect at a right angle and bisect each other. Let M be the point of intersection of the diagonals, so that MW = MY and MX = MZ.

We can use the Pythagorean theorem to find MW and MX, and then use the fact that they are equal to find WZ.

Using the Pythagorean theorem in right triangles WMX and WMY, we have:

MW² = WX² - MX²

= 17² - 5²

= 264

MY² = WY² - MW²

= 13² - 264

= 25

MX² = XZ² - MZ²

= 17² - 13²

= 144

Since MW = MY, we have MW = √(25)

= 5

Therefore, WZ = 2MX

= 2√(144)

The answer of the given question based on the probability is , the probability that at least 6 adults watch the news is approximately 0.755.

Probability is  measure of likelihood or chance of  event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain. Probability is used to analyze random experiments and events, and it is an essential concept in statistics, mathematics, and many other fields.

This is a binomial probability problem, where X follows a binomial distribution with n = 8 and p = 0.60. We want to find the probability that at least 6 adults watch the news, which can be written as:

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + ...

To solve , we use  binomial probability formula:

P(X = k) =(n choose k) *p^k *(1 - p)^(n - k)

where "n choose k" is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

Using this formula, we can find the probabilities for each value of k:

P(X = 6) = (8 choose 6) * 0.60⁶ * 0.40² = 0.311

P(X = 7) = (8 choose 7) * 0.60⁷ * 0.40¹ = 0.276

P(X = 8) = (8 choose 8) * 0.60⁸ * 0.40⁰ = 0.168

Note that we can also use  binomial probability table or  calculator with  binomial probability function to find the probabilities.

Then, we can add these probabilities to get the probability that at least 6 adults watch the news:

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + ... = 0.311 + 0.276 + 0.168 + ...

This is a infinite series, but we can stop at P(X = 8) since the probabilities become very small after that.

P(X ≥ 6) = 0.755

Therefore, the probability that at least 6 adults watch the news is approximately 0.755.
