Answer: they are parallel

Step-by-step explanation:

find slope of line m:

Use y2-y1/x2-x1

your m equation --> 9-15/10-3 which makes the slope of m = -6/7

find slope of line n:

Use y2-y1/x2-x1

your n equation --> 3-9/9-2 which makes the slope of n = -6/7

The slopes are the same, therefore line m and line n are parallel.

A random sample of 20 purchases showed the sample mean of $48.77 and the sample standard deviation s is $17.58. How large is the
laila [671]

Answer:

<h2>$5.03</h2>

Step-by-step explanation:

Given data          

Sample Mean (M):  $48.77  

Sample Size (n): 20

Standard Deviation (σ) :  $17.58

Confidence Level: 80%

 we know that z*-Values for 80% Confidence  Levels is 1.28

the expression for margin of error is given bellow\

MOE= z*σ/√n

We can now substitute into the expression and solve for the MOE as

MOE= 1.28*17.58/√20

MOE= 22.502/4.47

MOE= 22.502/4.47

MOE= 5.03

The margin of error for a 80 % confidence interval is $5.03

Pani-rosa [81]

Answer:

4. 34%

Step-by-step explanation:

By mixing 20% and 30%, it will be between 20 and 30, like 22, 24 or 28. You would need a higher concentration than 30 to mix in to get 34%.
