We have to determine if triangle PQR is similar to triangle XYZ or not.

To determine if the two triangles are similar, we use three postulates

AA, SSS, SAS.

AA means two angles must be equal in both triangles.

From picture we can see that only one angle is given so we can't be sure about other angles.

SSS means all sides are in same ratio but we have been given value of only one side. So that is also not applicable.

SAS means ratio of two sides from both traingles is equal and both triangles share a common angle but that is also not the given case.

Hence final answer is D. "Cannot be determined".

What is the scale factor from AABC to ADEF?

8_murik_8 [283]

Answer: 8

Step-by-step explanation:

We are going from a smaller triangle to a larger triangle, so the scale factor is greater than 1.

Eliminate A and D.

We know scale factor = (image)/(preimage), so the scale factor is 32/4 = 8

Construct the 95% confidence interval for the population mean using the appropriate distributions. a. A random sample of 50 peop

SSSSS [86.1K]

Answer: 95% confidence interval would be (26.01,29.39).

Step-by-step explanation:

Since we have given that

n = 50

Mean = 27.7

Standard deviation = 6.12

We need to construct 95% confidence interval for the population.

so, z = 1.96

So, it becomes,

$\bar{x}\pm z\times \dfrac{\sigma}{\sqrt{n}}\\\\=27.7\pm 1.96\times \dfrac{6.12}{\sqrt{50}}\\\\=27.7 \pm 1.69\\\\=(27.7-1.69,27.7+1.69)\\\\=(26.01,29.39)$

Hence, 95% confidence interval would be (26.01,29.39).

The system of equations to find the cost of one adult ticket, a, and the cost of one child ticket, c are Roy's; 6a+2c=66 Elisa's 5a+4c=62.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let's consider adults tickets be a and child tickets be c

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence, the system of equations

6a+2c=66------1

5a+4c=62-------2

solving simultaneously

6a+2c=66

5a+4c=62

Also,

12a+4c=132

-5a+4c=62

7a=70

a=$10

put a=70 in 1

6(10)+2c=66

60+2c=66

2c=66-60

2c=6

c=$3
