Answer:

-4

Step-by-step explanation:

The slope of the line is found by

m = (y2-y1)/(x2-x1)

    = (-7 - -19)/(-2 -1)

    = (-7+19)/(-2-1)

    = 12/-3

    = -4

pishuonlain [190]

Answer:

Null Hypothesis, H_0 : p \geq 45%    

Alternate Hypothesis, H_A : p < 45%

Step-by-step explanation:

We are given that the proportion of women in similar sales positions across the country in 2004 is less than 45%.

The collected random sample of size 50 showed that only 18 were women.

<u><em>Let p = proportion of women in similar sales positions across the country in 2004</em></u>

So, Null Hypothesis, H_0 : p \geq 45%    

Alternate Hypothesis, H_A : p < 45%

Here, <u><em>null hypothesis states that</em></u> the proportion of women in similar sales positions across the country in 2004 is more than or equal to 45%.

On the other hand, <u><em>alternate hypothesis states that</em></u> the proportion of women in similar sales positions across the country in 2004 is less than 45%.

The test statistics that would be used here is One-sample z proportion test statistics, i.e;

                        T.S.  =  \frac{\hat p -p}{\sqrt{\frac{\hta p(1-\hat p)}{n} } }  ~ N(0,1)

Hence, the above hypothesis is appropriate for the given situation.

X = 22 + 10x<br> How to find x?
GrogVix [38]

Answer:

x = -2.44

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 10x from both sides:

x (-10x) = 22 + 10x (-10x)

x - 10x = 22

-9x = 22

Isolate the variable, x. Divide -9 from both sides:

(-9x)/-9 = (22)/-9

x = 22/-9

x = -(22/9)

x = -2.44 (repeating).

x = -2.44 (rounded) is your answer.
