Adult panda weights are normally distributed with a mean of 200pounds and a standard deviation of 20 pounds. the largest pandas weigh over 250 pounds.

approximately what percent of the adult pandas weight over 250 pounds ?

0.62%

Step-by-step explanation:

Given: The means weight of the adult panda:

Standard deviation

Since,

For x = 250

Now, the probability of the adult pandas weight less than 250 pounds

Now, the probability of the adult pandas weight over than 250 pounds

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
