Answer: 31.7
Step-by-step explanation:
Felix mean= 9.4
Felix median= 7
Tyler's mean= 54
Tyler's median = 66
The mean of combined data will be the mean of Felix and the mean of Tyler. This will be:
= (9.4 + 54)/2
= 63.4/2
= 31.7

Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
You cannot measure the length of a ray of a pair of rays but you can measure a line segment
You can't change more than 100 percent
