Answer:
ok so. Your answer is that the population grew by about 3% (1,722,862 people)
Step-by-step explanation:
You would just solve 53,594,378 by 55,317,240. You would get a number right around 96.88 so you would round up to 96.9 or 97. From there, you would subtract 100-97 or 100-96.9 to get 3 or 3.1, that is how you know what percentage something grew or shrank by. :) hope this helps you
We have 89 ounces of 47% iodine.
We will add "x" ounces of 14% iodine to get a 29% iodine solution.
89 * .47 + .14x = .29 * (89 + x)
41.83 + .14x = 25.81 + .29x
16.02 = .15x
x = 106.80
So, we must add 106.80 ounces of 14% iodine to get a 29% iodine solution.
(for a total of 195.80 ounces)

Answer:
<h2><em><u>Option</u></em><em><u>:</u></em><em><u> </u></em><em><u>D</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
7,625,750,263
<em><u>When</u></em><em><u> </u></em><em><u>estimated</u></em><em><u>, </u></em>
8,000,000,000
= 8 × 1,000,000,000

If ages are normally distributed then using a significance level of 0.05 , we can claim that the population mean is greater than 24.
Given sample mean of 25 years , sample size of 16 ,standard deviation of 2 years.
We have to find whether the population average is greater than 24.
We have to use t test because n is less than 30. It is right tailed.
We have to first form Hypothesis.
:μ>24,
:μ<24.
t=X-μ/S/
t critical at 5% significance level and degree of freedom=15 (16-1)=1.7531
t=24-25/2/
=-1/0.5
=-2
Because 1.7531 is greater than -2 so we will accept the null hypothesis.
Hence we can say that the average of population is greater than 24.
