Answer:
Nine of the times for the first race were at least 16 seconds
Step-by-step explanation:
Here we have from the scatter plot, the times are given as
Time Frequency
19 2
18 2
17 2
16 3
15 1
Therefore, total number of times that are above 16 seconds in the first race is
3 + 2 + 2 + 2 = 9
Therefore, the first option is correct
24 1/2 or 24.5 is the answer
It will take them 6 hours to be 168 miles apart.
Answer:
Each eraser is $4.37
Step-by-step explanation:
38.83-3.87=34.96
34.96 divided by 8=4.37
These erasers are quite expensive...
Given the mean of 4 years
Standard Deviation of 0.8 years
We are looking for the probability of that CD for 3 years.
P = (probability of the CD - mean) / standard deviation
P = (4 - 3) / 0.8
P = 1.25
So the probability is 1.25
