18 * 3 = 54
4 * 40 = 160
160 + 54 = 214 (From here I will say that she doesn’t have enough money
Answer:
300pi ft³
Step-by-step explanation:
Volume of cylinder = pi×r²×h
Volume of cone = ⅓×pi×r²×h
Volume of cylinder is 3 times the volume of the cone
3(100pi) = 300pi ft³

Answer:
<u>A. p(hat) = .139</u>
We divide our sample population by the amount who tested positive. 14851/107109 = .139.
<u>B. 1.62 million</u>
We just multiply the p times the population. 11.69 M * .139 = 1.62 M
<u>C. No</u>
It depends upon the sample method. From what I can tell, I assume all conditions are met and it was not biased.
If it wasn't random, that is a problem, but we aren't given this information.
We can test if it's small enough. It can't be larger than 10% of the population. 107109 * 10 < 11.69 million, so it's small enough.
We can also test if it's large enough. np and nq must be greater than 10. 107100 * .139 > 10, 107100 * .861 > 10.
