The number of solutions for the given two line graph is; D: One Solution

<h3>How to Interpret Parallel Line graphs?</h3>

Since the two lines in the graph are not parallel, it means that both lines will intersect at some point.

Now, from the graph, we can see the following highlights;

The x-coordinate of the point of intersection is at x = 1.5

The y-coordinate of the point of intersection is at y = -0.75

Thus, the ordered pair that represents the solution is (1.5,-0.75)

Thus, the two line graph has only one solution

A certain store sells only T-shirts. Let the random variable X represent the number of T-shirts bought from the store on any day

faltersainse [42]

Answer:

$(a)\ \mu_y = 1125$

$(b)\ \sigma_y = 300$

Step-by-step explanation:

Given

$\mu_x = 75$ -- Mean of T-shirts

$\sigma_x = 20$ -- Standard deviation of T-shirts

$Rate = \$ 15$

Solving (a): The mean of the revenue $(\mu_y)$

To solve this, we use:

$\mu_y = Rate * \mu_x\\$

This gives:

$\mu_y = 15 * 75$

$\mu_y = 1125$

Solving (b): The standard deviation of the revenue $(\sigma_y)$

To solve this, we use:

$\sigma_y = \sqrt{Rate^2 * \sigma_2^2}$

This gives:

$\sigma_y = \sqrt{15^2 * 20^2}$

$\sigma_y = \sqrt{90000}$

$\sigma_y = 300$

A blueprint of a bedroom has a scale of 1 4 inch is equivalent to 1 foot. If the closet measures 1 2 inch by 3 4 inch on the blu

Murljashka [212]

Answer:

The actual dimensions of the closet are 2 ft by 3 ft.

Step-by-step explanation:

According to the scale, 1/4 inch <--> 1 foot

The closet dimensions on the scale are (1/2 inch, 3/4) or (2/4 inch, 3/4). Let the real closet dimensions be (x,y).

In this case, the rule of three can be applied to find the missing term of a proportion:

$x*\frac{1}{4} = 1*\frac{2}{4}\\x=2\\y*\frac{1}{4} = 1*\frac{3}{4}\\y=3$

The actual dimensions of the closet are 2 ft by 3 ft.

Question 1

Andrews [41]

The club currently have 25 members

Yolanda's club requires that 80% of the members be present for any vote. If at least 20 members must be present to have a vote, it means that 80% of the members in Yolanda's club is 20 members.

In order to determine the number of members in the club, use this formula:

Number of members in the club = least number of members that have to be present to vote / percentage of members that must be present to vote

least number of members that have to be present to vote = 20

percentage of people that must be present to vote = 80%

20 / 0.8 = 25 members
