Answer: B and D

Step-by-step explanation:

If you put those two into a calculator, they show up as the same answer. From the equation 2^5/6^5, the simplified version is 1/243, and B and D are both 1/243

Answer:

The alternate hypothesis statement is, p ≠ 0.75.

Step-by-step explanation:

Success rate for Lena at free throws in a basketball game is, p = 0.75.

She decided to practice a new technique for shooting her free-throws.

Lena attempted n = 50 free throws. Of these 50 free throws her success rate was, $\hat p=0.70$ .

To test whether the new technique produced significantly better or worse results she should use one-proportion z-test.

The hypothesis can be defined as:

H₀: The proportion of attempts made using this new technique is 75%, i.e. p = 0.75.

Hₐ: The proportion of attempts made using this new technique is different from 75%, i.e. p ≠ 0.75.

The alternative hypothesis indicates that the test is two-tailed.

This is because Lena is not sure if the new technique increases her success rate or decreases it.

Thus, the alternate hypothesis statement is, p ≠ 0.75.

One possible equation to solve is tan(x) = 4/15
That solves to roughly 15 degrees

==============================================================

Explanation:

Refer to the diagram below.

The segment AB is the player's height of 6 ft.

The segment CD is the hoop's height, which is 10 ft.

There is a point E on CD such that rectangle BACE forms. This will help us form ED later.

Angle EBD is what we're after, which I'll call x.

Since the free throw line is 15 ft from the basket, this means segments EB and AC are 15 ft each.

In rectangle BACE, the side EC is opposite AB. So both of those sides are 6 ft each.

Since CD = 10 and EC = 6, this must mean ED = CD-EC = 10-6 = 4.

---------------------------------------

To summarize, we found that ED = 4 and EB = 15.

We'll focus our attention entirely on triangle EBD

We have two known legs of the triangle, specifically the opposite and adjacent sides.

So we'll use the tangent ratio.

tan(angle) = opposite/adjacent

tan(B) = ED/EB

tan(x) = 4/15 .... is the equation to solve

x = arctan(4/15) .... same as inverse tangent or $\tan^{-1}$

x = 14.931417 ..... make sure to be in degree mode

x = 15 ..... rounding to the nearest whole degree

So that unknown angle in the diagram is approximately 15 degrees

3/4 and 0.95 would both result in a reduction.

Step-by-step explanation:

multiplying by anything less than 1 will make it smaller which both 3/4 and 0.95 are smaller than 1.
