The managers of 21 supermarkets counted the number of cars in their parking lots at noon on the same day. The results are shown in the list. 98, 100, 101, 102, 108, 109, 111, 118, 129, 132, 133, 135, 135, 145, 146, 146, 156, 170, 176, 180, 180 Suppose the number of cars in one of the parking lots with 180 cars is changed to 160 cars. Which statement about the median and interquartile range after this change is true?

A. The median and the interquartile range do not change.
B. The median and the interquartile range both decrease.
C. The median decreases, and the interquartile range does not change.
D. The median does not change, and the interquartile range decreases.​

answer: idk

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
