Ashipment of beach balls with a mean diameter of 28 cm and a standard deviation of 1.3 cm is normally distributed. by how many standard deviations does a beach ball with a diameter of 26.7 cm differ from the mean?
a. 1
b. 1.3
c. 2
d. 3

a. 1

Step-by-step explanation:

Given : Population mean :

Standard deviation :

Let n be the number of times  a beach ball with a diameter of 26.7 cm differ from the mean.

Then, we have

Hence, a beach ball with a diameter of 26.7 cm is 1 standard deviation differ from the mean.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

yes because they have the same amount of green and blur marbles.
