Answer:

Step-by-step explanation:

Part 1

P(z < -1.45)

Using the z score table

P =

Part 2

We solve using z score formula

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

a) P(X >52)

x = 52

Mean = 60

Standard deviation = 8

z = 52 - 60/8

z = -1

P-value from Z-Table:

P(x<52) = 0.15866

P(x>52) = 1 - P(x<52) = 0.84134

b) P(48 < x < 64)

Anthony's weight is nine pounds more than twice his brothers weight. Anthony's weighs 59 pounds. how much does his brother weigh
ahrayia [7]
A = Anthony's weight
B = Anthony's brother's weight

  A = 2B + 9   Plug in Anthony's weight
59 = 2B + 9   Subtract 9 from both sides
50 = 2B   DIvide both sides by B
25 = B   Switch the sides to make it easier to read
  B = 25

Anthony's brother weighs 25 pounds.
