X-3y=12
3y=x-12
y=1/3x-4
parallel means same gradient, which is 1/3.
Use formula y-y1=m(x-x1), m=gradient and y1 is y coordinate of point and x1 is x coordinate of point.
y-4=1/3[x-(-3)]
y-4=x/3+1
y=x/3+5
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%

Answer:
(50,55,60,....)
Step-by-step explanation:
Given that a health insurance plan has a $50 enrollment fee and a copayment of $5 for each doctor visit.
The function f(x) = 5x + 50 gives the cost of x doctor visits
Here x is the no of visits.
No of visits is an independent variable while f(x) total cost is a dependent variable on x
slope = 5 which indicates for each visit extra, extra cost is 5 dollars
Enrollment fee = 50 = fixed cost
Hence domain would be
x =0,1,2,3.....
So range is
(50,55,60,....)
