The correct answer for the question that is being presented above is this one: "B. 68%." The weights of a bat in a zoo are normally distributed with a mean of 2.2 pounds and a standard deviation of 0.3 pounds. The percent of the bats at the zoo that weigh 1.9 pound and 2.5 pounds is <span>B. 68%</span>
Answer:
0.1 , 0.2 , 0.05
Step-by-step explanation:
*each column adds to 1*
20 x 1/2 = 10
1/2 x 20 x 0.1 = 1
top left box = 0.1
; 5 x 2 x 0.1 = 1
1/2 x 10 = 5
; 0.2 x 1/2 x 10 = 1
bottom middle box = 0.2
; 5 x 1 x 0.2 = 1
; 2 x 10 x 0.05 = 1
middle right box = 0.05
; 20 x 1 x 0.05
96*72=6912
One ton is $72
You have 96 tons
So you take $72 96 times
