What is the equation of a line, in Slope Intercept Form, with a slope of 1/3 and passes through the point (9, 7)?
levacccp [35]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m=\dfrac{1}{3}\to y=\dfrac{1}{3}x+b

and point (9, 7). Substitute:

7=\dfrac{1}{3}(9)+b

7=3+b      <em>subtract 3 from both sides</em>

4=b\to b=4

Answer: y=\dfrac{1}{3}x+4

A normally distributed population has a mean of 250 pounds
Dima020 [189]

Answer: 0.9746

Step-by-step explanation:

Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.

i.e. \mu=250 \sigma=10

Sample size : n= 20

Let \overline{x} sample mean values.

Then, the probability that this sample will have a mean value between 245  and 255 be

P(245

Hence , the probability that this sample will have a mean value between 245  and 255 is 0.9746 .
