explanation:
h(x)= -x-4
h(-6) = -(-6)-4
h(-6) = 6-4
h(-6) = 2
The answer for this question is 12 56
Answer:
84.134%
Step-by-step explanation:
We solve this question using the z score formula.
The formula for calculating a z-score is z = (x-μ)/σ
where
x is the raw score
μ is the population mean
σ is the population standard deviation.
We are were asked in the question that:
Suppose that adult women in China have heights that are normally distributed with a
mean = 155 centimeters
standard deviation = 8 centimeters. Of the Chinese women, what percent are shorter than 163cm?
Using the z score formula
z = (x-μ)/σ
z = (163 - 155)/8
z = 8/8
z = 1
Determining the Probability value from Z-Table:
P(x ≤ 163) = P(x < 163)
= 0.84134
Converting to percentage
= 0.84134 × 100%
= 84.134%
The percent of Chinese women that are shorter than 163cm is 84.134%

umm im sorry but there is no graph
Answer:
Step-by-step explanation:
The scale factor is 2/3
2/3=2*2/2*3=4/6
2/3=2*3/3*3=6/9
