Answer:
a) 0.383
b) 0.375
Step-by-step explanation:
a) Calculate each z-score.
z = (x − μ) / σ
z₁ = (112 − 118) / 12 = -0.5
z₂ = (124 − 118) / 12 = 0.5
Use a calculator or z-score table to find the probability.
P(-0.5 < Z < 0.5) = 0.6915 − 0.3085 = 0.383
b) 0.383 × 16 ≈ 6. So the expected proportion would be 6/16 = 0.375.
Multiplication property of equality
Answer:
they said If any two lines intersect several parallel lines, their segments
determined on one of the lines are proportional to the segments
corresponding in the other.
Step-by-step explanation:
I think they said that
For the equation f(x)=-2/3x+290, the y-int is 290 so you would plot that down on for positive 290 and from there rise upwards two times and run left 3 times for -2/3 is your slope.
