What is the IQR?
Serga [27]
From my understanding and calculations the IQR would be 30
Answer
A. 196,608
Step-by-step explanation:
-12/3 = -4
48 / -12 = -4 and -192 / 48 = -4
This is a geometric sequence with common ratio -4.
an = a1 r^(n -1) so:-
9th term (a9) = 3*(-4)^(9-1)
= 196,608
Answer:
91% of the time the auto will get less than 26 mpg
Step-by-step explanation:
Think of (or draw) the standard normal curve. Mark the mean (22.0). Then one standard deviation above the mean would be 22.0 + 3.0, or 25.0. Two would be 22.0 + 2(3.0), or 28.0. Finallyl, draw a vertical line at 26.0.
Our task is to determine the area under the curve to the left of 26.0.
Using a basic calculator with built-in statistical functions, we find this area as follows:
normcdf(-100, 26.0, 22.0, 3.0) = 0.9088, which is the desired probability: 91% of the time the auto will get less than 26 mpg.
