Answer:
C:12
Step-by-step explanation:
should be 13.5
The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set.
so the middle number of 10,11,12,15,17,19 is 13.5 since 12+15=27/2=13.5
the closest answer choice is C! Hope this helped!
Answer:
B. 93%
Step-by-step explanation:
Find the z-score:
z = (x − μ) / σ
z = (122 − 100) / 15
z = 1.47
Find the probability using a calculator or z-score table.
P(Z < 1.47) = 0.93
Answer: 18
Step-by-step explanation:
this is because complementary angles add up to 90 degrees so you would just subtract 72 from 90 to get your answer :)
If the initial time was 60 seconds and 18 seconds have passed,

There would be 42 seconds left.
