Answer:
the answer would be C
Step-by-step explanation:
if you replace y with 5 and x with -3 they should make the equations "solvable"
Answer: C) There is a probability that the outcome is within 1 standard deviation of the mean.
Step-by-step explanation:
The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. According to the rule,
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations
Therefore, the correct answer is
C) There is a probability that the outcome is within 1 standard deviation of the mean.
Answer:
Step-by-step explanation:
InterQuartile Range is the difference in 3rd Quartile and 1st Quartile.
In box-plots, you can see two tails and a box. The left side of the box is the "first quartile" and the right edge of the box is "third quartile".
<u>For TOP BOX PLOT:</u>
3rd Quartile = 41
1st Quartile = 24
So, IQR (interquartile range) = 41 - 24 = 17
<u>For BOTTOM BOX PLOT:</u>
3rd Quartile = 35
1st Quartile = 28
IQR = 35 - 28 = 7
Difference in two IQRs is:
17 - 7 = 10
Correct answer is A
Answer:
245 pounds in 7 days
Step-by-step explanation:
35 pounds= 1 day for one person
35*7=245
