Answer:
ok first we add 9 and 29 together
38
now we add 90
128
so the other angle is
52
so we just use the formulas
and
Side a = 26.56371
Side b = 43.14662
Side c = 34
so the side with a x on it is 26.6
so know we have to do the same thing but not including the top part
ok so the side with x on it is 18.8
so 26.6-18.8=7.8
x=7.8
*WARNING* This shoud be close to the answer but may to up to a couple dp higher or lower sorry i just don't have time to be more accurate
Hope This Helps!!!
Answer:
answer d 2/6
which is 1/3 =0.333333333
(0.300 kW) * (24 h/day) * (30 day) * ($0.07/kWh) = $15.12

Answer: Choice D</h3>
To calculate a point estimate, we need to know the sample size.
===========================================================
Explanation:
Let's go through the answer choices.
- A) False. A sample statistic could equal to the population parameter. It won't always happen, but it might happen sometimes (in rare cases).
- B) False. Point estimates are only defined for populations. They estimate a population parameter. For example, the sample mean xbar is a point estimate of the population mean (mu).
- C) False. In practice, we will hardly know anything about the population. This includes the population size. The goal of statistics is to measure population parameters by using sample statistics as estimation methods.
- D) True. We can easily calculate the sample size because it is relatively much smaller compared to the population. Plus, when selecting the sample, the sample size is often pre-determined to some set number. The sample size will help us determine things like the sample mean and the sample proportion.
14 years. In 14 years Chloe will be 22 and Sheila will be 28. 22+28 is 50.
