The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.

According to my TI-83 calculator,

normalcdf(110,120, 100, 15) = 0.16, or 16%.

PLZZ HELP!! WILL MARK BRAINLIEST PLZZ!!!
grandymaker [24]

Answer:

see below

Step-by-step explanation:  7  1  16   33

  y  = x²   translated t the point (3, 2)         y = 0 when x = 0

  y =  (x - 3)²    moves the function three units to the right     y = 0 when x = -3

  y  = (x-3)² + 2  moves the function up 2 units      y = 2 when x = -3

  y = (x-3)² + 2

  y = x² - 6x + 9 + 2

  y = x² - 6x +11

graph the equations x²,  (x-3)² + 2,  and x² - 6x + 11   to verify (I did)

Help? I'm pretty confuse on both of these? Please explain?

35 is the first answer (BAE ~ DAC)
36. We must divide 20 by 2 to get 10 because all the other sides are 2x the size. 3x-5=10   (Add 5) 3x=15 (Divide by 3) x=5 so the last answer choice is correct.
