Answer:
Mean: 1.5
Standard Deviation: 0.9
Step-by-step explanation:
2/3 of the pages have diagrams, and N is the number of pages Harlee reads to reach a page with a diagram. In order to find the mean, divide 1/(2/3) to get 1.5 as your mean, and then divide sqrt(1-(2/3))/2/3 to get .8660, which rounds to .9.
Answer:
3/4
Step-by-step explanation:
1/4 + 2/4 = 3/4
5 + 10 = 15
The first one is -4 and the second one is 6.
It should be 3 because you are going to be using the formation of 3√ 3•3•3
.
2 times 2.5 times 1.5 times 10 equals to 75 square meters.
