Step-by-step explanation:
48: the number of members
1,210: amount of money they already have
6,000: amount they need
by simply dividing the goal with amount of people, you will get the amount each person needs to make.
6000 ÷ 48 = 125
48x - 1,210 = 6000
x = how much each person needs to make
48 × 125 = 6000
i think this is what your looking for? if not just comment dont report and i will ask for more details.
Answer:
CI = 21 ± 0.365
Step-by-step explanation:
The confidence interval is:
CI = x ± SE * CV
where x is the sample mean, SE is the standard error, and CV is the critical value (either t score or z score).
Here, x = 21.
The standard error for a sample mean is:
SE = σ / √n
SE = 3.2 / √510
SE = 0.142
The critical value is looked up in a table or found with a calculator. But first, we must find the alpha level and the critical probability.
α = 1 - 0.99 = 0.01
p* = 1 - (α/2) = 1 - (0.01/2) = 0.995
Using a calculator or a z-score table:
P(x<z) = 0.995
z = 2.576
Therefore:
CI = 21 ± 0.142 × 2.576
CI = 21 ± 0.365
Round as needed.
10 because
1 quarter = 1/4
so 24 divided by 1/4 = 6
6 + 4 = 10
so john has 10 eggs
hope this helps!!
