Suppose the null hypothesis is not rejected. state the conclusion based on the results of the test.
six years ago, 12.6% of the registered births were to teenage mothers. a sociologist believes that the percentage has increased since then.
which of the following is the correct conclusion!
(a) there is sufficient evidence to conclude that the percentage of teenage mothers has increased.
(b) there is not sufficient evidence to conclude that the percentage of teenage mothers has remained the same.
(c) there is sufficient evidence to conclude that the percentage of teenage mothers has remained the same.
(d) there is not sufficient evidence to conclude that the percentage of teenage mothers has increased.

a negative exponent is translated as follows:

so, we have

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
