A=#nickels, b=#quarters
5a + 25b = 410 total value
5(a + 5b) = 410
a + 5b = 82
a + b = 30 total no. of coins
subtracting . . . 4b = 52
thus b = 13 and a = 17
13 quarters and 17 nickels = 13*25 + 17*5 = 410 = $4.10
Answer:
31
Step-by-step explanation:
16(3) - 3(-1) + 5(-4)
48 + 3 - 20
31
by taking the quotient between the volume in the pot and the volume of each serving, we conclude that there are 12 servings.
<h3>
How many servings does the pot contain?</h3>
The number of servings is given by the quotient between the volume in the pot and the volume of each serving, so we have:
- Volume in the pot = 3/4 gallon.
- Volume of each serving = 1/16 gallon.
N = (3/4)*/(1/16) = 12
So there are 12 servings in the pot.

Answer:
80
Explanation:
The mean of the distribution of sample means always target the population mean. What this line tells is that whatever the population mean will be, the mean of the distribution of sample means will be same. Since the population mean is 80, the mean of distribution of sample means will also be 80.
However, the standard deviation of the sample distributions is different and is equal to the population standard deviation divided by square root of sample size. So in this case the standard deviation of distribution of sample means will be 6 .
