Step-by-step explanation:
Let 
The slope of the line through these two points is
So the slope-intercept form of the line passing through the two points is
To find b, we use either point into our equation. Let's use (-1, -8):
Therefore, the slope-intercept form of the equation for the line is
The standard form of the equation can be written as

Set up your problem like this x/500 and 70/100. 500 x 70 / 100= 350 350 millimeters would be your answer
Answer:
27
Step-by-step explanation:
To evaluate f(8) substitute x = 8 into f(x)
f(8) = 
× 8² - (
× 8 + 3)
= × 64 - (2 + 3)
= 32 - 5
= 27
Answer:
90% confidence interval for the population mean is between a lower limit of $92.18 and an upper limit of $107.82.
Step-by-step explanation:
Confidence interval for a population mean is given as mean +/- margin of error (E)
mean = $100
sd = $25.20
n = 30
degree of freedom = n-1 = 30-1 = 29
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 29 degrees of freedom and 10% significance level is 1.699
E = t×sd/√n = 1.699×25.20/√30 = $7.82
Lower limit of population mean = mean - E = 100 - 7.82 = $92.18
Upper limit of population mean = mean + E = 100 + 7.82 = $107.82
90% confidence interval is ($92.18, $107.82)
