60+72=(12x5) +(12x6)=12(5+6)
60=12x5
72=12x6
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:
length = 18 ft
Step-by-step explanation:
Let w = width
L = w+7
Area = l*w
198 = (w+7) (w)
Distribute
198 = w^2 +7w
Subtract 198 from each side
0 = w^2 +7w -198
Factor
What 2 numbers multiply to -198 and add to 7
18* -11 = -198
18+-11 = 7
0=(w+18) (w-11)
Using the zero product property
w+18 =0 w-11=0
w= -18 w=11
We cannot have negative width so w=11
We want the length
l = w+7
l = 11+7 = 18
Answer:
C) 113 m^2
Step-by-step explanation:
diameter/2 =radius = 12/2 = 6
area = 6^2(3.14) = 6x6x3.14 = 113 m^2
