Answer:
0.7102
0.8943
0.3696
Step - by - Step Explanation :
A.) Between $1320 and $970
P(Z < 1300) - P(Z < 970)
find the Zscore of each scores and their corresponding probability uinag the standard distribution table :
P(Z < (x - μ) /σ) - P(Z < (x - μ) / σ))
P(Z < (1320 - 1250) /120) - P(Z < (970 - 1250) / 120))
P(Z < 0.5833) - P(Z < - 2.333)
0.7200 - 0.0098 = 0.7102 (Standard
=0.7102
B.)Under 1400
x = 1400
P(Z < 400)
P(Z < (x - μ) /σ)
P(Z < (1400 - 1250) /120)
P(Z < 1.25) = 0.8943
C.) Over 1290
P(Z > 1290)
P(Z < (x - μ) /σ)
P(Z > (1290 - 1250) /120 = 0.3333
P(Z > z) = 1 - P(Z < 0.3333) = P(Z < 0.3333) = 0.6304
P(Z > 0.3333) = 1 - 0.6304 = 0.3696
Answer:
The industrialization of the late nineteenth century brought on rapid urbanization. The increasing factory businesses created many job opportunities in cities, and people began to flock from rural, farm areas, to large urban locations. Minorities and immigrants added to these n
Answer:
Height = 13.86 cm
Step-by-step explanation:
1. Find the length of each side
48/3 = 16
2. cut the triangle in half.
Base = 8 Hypotenuse = 16
3. use the formula A^2 + B^2 = C^2
(16^2 - 8^2)^(1/2) = 13.86 cm
28% of x = 100.80
.28 × x = 100.80
.28x = 100.80
x = 100.80/.28
x = 360
