Answer:

H0 : p = 0.75  against    H1: p > 0.75  One tailed test.

Step-by-step explanation:

We state our null and alternative hypotheses as

H0 : p = 0.75  against    H1: p > 0.75  One tailed test.

In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.

The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.

As H0 is supposed to be less than we choose H1 to be greater than equality.

The location of the mid point between (-15,4) (2,-10)
frozen [14]

Answer:

The answer is

<h2>( -  \frac{13}{2} , \:  - 3)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M  = ( \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-15,4) (2,-10)

The midpoint is

<h3>M = ( \frac{ - 15 + 2}{2}  , \:  \frac{4 - 10}{2}  ) \\  = ( -  \frac{13}{2} , \:  -  \frac{6}{2} )</h3>

We have the final answer as

<h3>( -  \frac{13}{2} , \:  - 3)</h3>

Hope this helps you

Gavin was thinking of a number. Gavin halves the number and gets an answer of 34.3. Form an equation with x as information.
Lostsunrise [7]

Gavin's number is 68.6

Equation: 1/2(x) = 34.3

Use inverse operations on both sides.

1/2(x) = 1x or x = 34.3(2)

34.3(2) = 68.6

Thus, x equals 68.6

Leya [2.2K]
The height of a dam:
h = x + 1.65 m,
where:
x = 90 m · tan 26°
x = 90 · 0.4877
x = 43.90
h = 43.90 m + 1.65 m = 45.55 m
Answer: 
The height of the dam is 45.5 m.
