Kaylis [27]

Answer:

$Total\ amount\ of\ paint\ mike\ mixes\ is\ \frac{19}{24}\ gallons$

Step-by-step explanation:

As given

$Mike\ is\ mixing\ paint\ for\ his\ walls.$

$He\ mixes\ \frac{1}{6}\ gallon\ blue\ paint\ and\ \frac{5}{8} \ gallon\ green\ paint\ in\ a\ large\ container.$

Thus

$Total\ amount\ of\ paint\ mike\ mixes = \frac{1}{6} + \frac{5}{8}$

L.C.M of (6,8) = 24

Than

$Total\ amount\ of\ paint\ mike\ mixes = \frac{1\times 4 + 5\times 3}{24}$

$Total\ amount\ of\ paint\ mike\ mixes = \frac{4+ 15}{24}$

$Total\ amount\ of\ paint\ mike\ mixes = \frac{19}{24}\ gallons$

Joseph has $3.00 in his piggy bank and he adds $0.75 each day. Kelsey has $5.25 in her piggy bank and she spends $0.25 each day.

12345 [234]

Answer:

They will have the same amount of money in their piggy banks when they each reach $6. (4 days for Joseph, 3 for Kelsey.)

Step-by-step explanation:

Joseph has $3.00 and will add $0.75 cents to it each day. So for the first day he will have $3.75. Then, $4.50. Then, $5.25. Then on the fourth day, he will have $6.

Kelsey has $5.25 and will add $0.25 each day. For the first day, she will have $5.50 in her piggy bank. Then, $5.75. Then $6.

Valentin [98]

Answer:

a) $H_{0} = 9.5$

b) $H_{a} < 9.5$

Step-by-step explanation:

The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness.

At the null hypothesis, we test if the value we find is equal to the expected value, that is:

$H_{0} = 9.5$

Test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population

Lower, which means that the alternate hypothesis, we test if the value we find is lower than the expected value, that is:

$H_{a} < 9.5$
