Answer:
18/36 or 1/2
Step-by-step explanation:
There are 18 nickels, which is the numerator.
You add all the numbers together to get the denominator, which is 12+6+18=36.
Then, you put the two values in a fraction - 18/36
and simplify, to get you 1/2.
42 hundredths as a decimal is 0.42
Y/3 + 1/4 = 5/12
4y/12 + 3/12 = 5/12
4y/12 = 2/12
4y = 2
/4 /4
y = 1/2
Therefore y = 1/2
Answer:
<u>The sample that best represents the population is the sample of the last eight friends </u>
Step-by-step explanation:
Let's find out the sample that best represents the population, this way:
Mean of the number of text messages a group of 24 friends sent in one week = 10,700/24 = 445.83
Mean of the sample of the first six friends = 1,850/6 = 308.33
Mean of the sample of the first ten friends = 3,300/10 = 330
Mean of the sample of the last twelve friends = 6,500/12 = 541.67
Mean of the sample of the last eight friends = 4,150/8 = 518.75
<u>The sample that best represents the population is the sample of the last eight friends, because its mean is the closest to the population mean (445.83 and 518.75)</u>
