A:
starting quadrant: Q/O (can’t tell, top left)
ending quadrant: S
(discovered by plotting the points on the graph)

B:
The difference between the starting point and the ending point is 10.8 on the on the x-axis. The points are related because they share the same position on the y-axis and is placed on the opposite side of the x-axis.

Determine the equation of the line shown in the graph: y = −1 y = 0 x = −1 x = 0

BaLLatris [955]

Answer:

Option C.

Step-by-step explanation:

If a vertical line intersects the x-axis at point (c,0), then the equation of line is x=c.

From the given figure it is clear that it is a vertical line and it intersects the x-axis at (-1,0). There are infinite values of y at x=-1.

So, the equation of given line is

$x=-1$

Therefore, the correct option is C.

Kryger [21]

Answer:

$a^{12}$

Step-by-step explanation:

Identity Used : $a^x \times a^y = a^{x+ y}$

$a^5 \times a^7 = a^{5 + 7} = a^{12}$

Assume that it is true that people can not tell the difference between Coke and Pepsi. If a sample of 15 people participated in

pantera1 [17]

Answer:

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they can tell the difference between Coke and pepsi, or they cannot. The probability that a person has o telling the difference between Coke and pepsi is independent from each other. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to the normal distribution if

$np \geq 10$

and

$n(1-p)\geq 10$

In this problem, we have that:

$n = 15$

First condition

$np \geq 10$

$15p \geq 10$

$p \geq \frac{10}{15}$

$p \geq \frac{2}{3}$

Second condition

$n(1-p) \geq 10$

$15(1-p) \geq 10$

$15 - 15p \geq 10$

$-15p \geq -5$

Multiplying by -1

$15p \leq 5$

$p \leq \frac{1}{3}$

p cannot be at the at the same time greather than 2/3 and lesser than 1/3. So we cannot assume that the sampling distribution of the proportion of people that correctly chose Pepsi is normal.

I only need help with #10 :) offering 10 pts

Semenov [28]

Answer:

The length of one side of the square is 3.

Step-by-step explanation:

The perimeter of any given shape is all of the sides added together. So, the perimeter of the triangle is 5x + 4x + 3x. Added together, 12x.

The perimeter of the square is (x + 2)*4. Distributed, it's 4x + 8. Since we know they're equal, set it up like this:

12x = 4x + 8

You then find that x = 1. Plug that into one side of the square, x + 2, to get 3.

Please help thank you.

Hello!

The degrees in a circle add to 360°

Since WZ is a diameter the angles on one side of the line add to 180°

We know that the angles to the right of WZ add to 180 and the angle of XW is 63.

We add these to get ZWX

180 + 63 = 243

The answer is 243°

Hope this helps!
