The average commute for 95% of the students is between 19.0 and 4.2 miles.
The average distance is 19 miles.
Therefore, the standard deviation is 4.2 miles.
A) 2.7 = 19 - a(4.2)
where;
a deviates from the mean by a certain number of standard deviations. Thus;
a = (19 - 2.7) ÷ 4.2
a = 3
In a normal distribution, 3 standard deviations from the mean indicate that 95% of the data falls within that range.
B) The data are 2 standard deviations apart from the mean at the 95% confidence level. Thus;
CI = 19 ± 2(4.2)
CI = (18 - 10.2) OR (18 + 10.2)
CI = (7.8, 28.2)

Answer: Look at explanation
Step-by-step explanation:
32 = 2 x 2 x 2 x 2 x 2
27 = 3 x 3 x 3
16 = 2 x 2 x 2 x 2
No as 32 can be broken down to 8 and 4 and not just pime and not prime
Answer:
B. Area = 256pi & Circumference = 32pi
Step-by-step explanation:
Area = pi r^2
A = pi (16)^2
A = 256pi
Circumference = 2pi r
C = 2(pi)(16)
C = 32pi
because a midpoint mean middle so A----------M----------B
AM is 1/2 of AB as well as BM is 1/2 of AB
4------------5----------6 if 5 is the midpoint how much is between 4 and 5 and 5 and 6
Answer:
B) In Quadrant IV
Step-by-step explanation:
You move 7 units to the right on the x-axis. Then you move 10 units down the y-axis. The point will then land on quadrant IV.
