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>
Answer:
2
Step-by-step explanation:
3-5 = -2
absolute value of -2 is 2.
Answer:
C. 2.01,1.48,1.237,1.234,1.2
Step-by-step explanation:
Additive inverses are numbers that add up to zero, such as 1 and -1.
Z is the additive inverse of -1/9, so z is 1.9.
1.9 + -1.9 =0.
Drag the -1.9 icon to just one mark to the right of -2 on the number line, since each dash equals 0.1.
Drag z to just one mark to the left of 2 on the number line.
The sum will be zero, so drag the sum icon to 0 on the number line.
