**Answer:**

**Step-by-step explanation:**

Every triangle's angles MUST add up to 180. Therefore, 43 + 43 + (6-8x) must be equal to 180. So:

43 + 43 + (6 - 8x) = 180

86 + (6 - 8x) = 180

6 - 8x = 94

-8x = 88

**x = -11**

X=11 i am not sure about it

(-5 • 4)^3

A. (-5)^3•4^3

B. -15^3•12

C. -15•12

D. -8•7

### Answers

**Answer:**

Its A

**Step-by-step explanation:**

You must distribute exponents outside of parentheses to each

A = -5^3 × 4^3

B = multiplies each by 3 then raises 1 to the third, very off

C = just multiplied each by 3

D = very off, added by 3

(-5 • 4)^3 = -8000

A. (-5)^3 = -125

4^3 = 64

-125 • 64 = -8000

Answer:

H0: Births occur with the same frequency on the different days of the week.

H1: At least one day has a different frequency of births than the other days.

Step-by-step explanation:

The null hypothesis is that births occur with equal frequency for each day of the week, as for the alternative which will be the opposite of the null, will e the claim that, the frequency for atleast one if not all of the weeks are different.

Hence,

### Answers

**Answer:**

the middle one , just check the letters

**Answer: Choice B (middle choice)**

Explanation:

If you reflected the top triangle over line m, then you'd get what is shown in answer choice C. The two triangles are the same size here, so no dilation has been applied yet. We can rule out choice C for this reason.

After shrinking the bottom triangle, you end up with the diagram in choice B. This is why it's the answer.

Choice A can be ruled out because it appears that your teacher has applied an extra vertical axis reflection to swap the positions of X' and Z'. We should have X' somewhere near and below point X (as choice B indicates). A similar story applies to points Z and Z' as well.
