The bottom square portion would be 10 x 10 = 100 square inches.
The area of the triangle would be 1/2 x base x height.
The base is 10 - 6 = 4 inches.
The height is 16 -10 = 6 inches.
Area = 1/2 x 4 x 6 = 12 square inches.
Total area = 100 + 12 = 112 square inches.
as a decimal is <span>0.385</span>
First we calculate how many ways you can choose four books from a set of eight.
We use the formula n! / [r! * (n-r)!]
8! / [4! * 4!]
= 8*7*6*5 / 4*3*2*1 = 70 ways
Then we have to calculate how many permutations can be made from 4 objects which equals 4*3*2*1 = 24
So, the TOTAL number of ways = 70 * 24 = 1,680
Answer:
difference in the proportion = 0.0452
Step-by-step explanation:
x1 = 27, n1 = 193,
p1 = 27/193
p1 = 0.1399
x2 = 16, n2 = 169,
p2 = 16/169
p2 = 0.0947
a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.
p1 - p2 = 0.1399 - 0.0947
p1 - p2 = 0.0452
The probability that Alexa spins an orange is zero. Since there is no orange on the spinner, there is no way for her to get an orange. Hope this helped!
