A doctor is using a growth chart for baby girls that indicates a 12-month-old baby girl has a mean weight of 21.1 pounds with a standard deviation of about 2.21 pounds. Assume that the weights are approximately normally distributed.

a) What is the probability that a randomly chosen 12-month-old baby girl weighs less than 20.13 pounds?

b) What is the probability that a randomly chosen 12-month-old baby girl weighs more than 23.84 pounds?

c) What proportion of 12-month-old baby girls weigh between 19.6 and 22.15 pounds?

its d. the first coordintaes are 10,32

step-by-step explanation:

its adding 5.5 each time

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
