A random sample of 108 customers was taken in a shopping mall. The mean number of items purchased by the customers in the sample was 3.9 with a standard deviation of 1. The median was 4.4, and the mode was 4. A graph shows that the distribution of the data is highly skewed to the left. A store manager wants to calculate the probability that a customer will purchase at least 4 items. Which statement is true?

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
