Answer:

$1,500

Step-by-step explanation:

Divide the 23 years into 4.5, then take the $47,000 given and reduce it by 1/2 depending on the answer, then round.

In this case: divide 23 into 4.5. The result ends in 5.1. Reduce the $47,000 by 1/2 five times to get your result, the round it tp the nearest 100.

Hope this helps! :)

Find the distance between the points (1, 5) and (1, -4). 3 √(41) 9

8_murik_8 [283]

Answer:

The distance between the givens points is 9 unit

Step-by-step explanation:

Given points are as :

A = ( 1 , 5 )

B = ( 1 , - 4 )

So, The Distance between points A and B = AB

Now, From Distance formula

AB = $\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}$

Or, AB = $\sqrt{(1 - 1)^{2}+( - 4 - 5)^{2}}$

Or, AB = $\sqrt{0 +81}$

Or, AB = $\sqrt{81}$ = 9

Hence The distance between the givens points is 9 unit Answer

hichkok12 [17]

Answer:

The statistic for this case would be given by:

$z=\frac{0.18 -0.1}{\sqrt{\frac{0.1(1-0.1)}{100}}}=2.67$

Step-by-step explanation:

Infromation provided

n=100 represent the random sample selected

X=18 represent the people who rates Pepsi as being "concerned with my health"

$\hat p=\frac{18}{100}=0.18$ estimated proportion of people who rates Pepsi as being "concerned with my health"

$p_o=0.1$ is the value that reference to compare

z would represent the statistic

Hypothesis to test

For this case we can assume that the interest is check if the proportion of people who rates Pepsi as being "concerned with my health" is equal to 0.1 or not , then the system of hypothesis are:

Null hypothesis: $p=0.1$

Alternative hypothesis: $p \neq 0.1$

The satistic for this one sample proportion test is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing the info given we got:

$z=\frac{0.18 -0.1}{\sqrt{\frac{0.1(1-0.1)}{100}}}=2.67$
