K.Brew sells a wide variety of outdoor equipment and clothing. The company sells both through mail order and via the internet. R
Elan Coil [88]

Answer:

Step-by-step explanation:

The formula for determining the confidence interval for the difference of two population means is expressed as

Confidence interval = (x1 - x2) ± z√(s²/n1 + s2²/n2)

Where

x1 = mean sale amount for mail order sales = 82.70

x2 = mean sale amount for internet sales = 66.9

s1 = sample standard deviation for mail order sales = 16.25

s2 = sample standard deviation for internet sales = 20.25

n1 = number of mail order sales = 17

n2 = number of internet sales = 10

For a 99% confidence interval, we would determine the z score from the t distribution table because the number of samples are small

Degree of freedom =

(n1 - 1) + (n2 - 1) = (17 - 1) + (10 - 1) = 25

z = 2.787

Margin of error =

z√(s²/n1 + s2²/n2) = 2.787√(16.25²/17 + 20.25²/10) = 20.956190

Please Help What is the value of the expression? −34+(1/10÷2/5)
sweet-ann [11.9K]
Regarding your (1/10 divided by 2/5):  I'm going to regard this as

(1/10) divided by (2/5).  

First, write 

 1
---         
10

Invert the fraction 2/5 and then multiply 1/10 by 5/2:

1(5)
-------- = 1/4, after reducing  5/10.
10(2)

Thus, <span>−34+(1/10÷2/5) yields -34 + 1/4, or   -33 3/4.</span>
