First you’d start off by finding the volume of the rectangular prism on the bottom. The formula for this is lwh or (length*width*height) so you’d plug in the numbers and get 4*4*5 which multiplies out to be 80inches cubed. Next you’d have to find the volume of the pyramid by using the formula lwh/3 or ((length*width*height)/3) so it would be ((4*4*6)/3) and that equals 32inches cubed. Finally, you add the 2 volumes together so 80inches cubed+32inches cubed and get 112inches cubed. Hope this helps

How to find the critical value ?

Critical probability (p*) = 1 - (Alpha / 2), where Alpha is equal to 1 - (the confidence level / 100), is the unit statisticians use to determine the margin of error within a set of data in statistics.

The critical value for α = 0.13 is $z_{c} = \frac{z_{1} - \alpha }{2}$

The corresponding confidence interval is computed as shown below

$CI = (X1_{1} - X_{2}- z_{c} \sqrt{\frac{a_{1}^{2}}{n_{1} } + \frac{a_{2}^{2}}{n_{2} }} , X1_{1} - X_{2}+z_{c} \sqrt{\frac{a_{1}^{2}}{n_{1} } + \frac{a_{2}^{2}}{n_{2} }} )$

$CI = (2.1 - 1.4- 1.514\sqrt{\frac{1^{2}}{37 } + \frac{0.5_{2}^{2}}{38 }} , 2.1 - 1.4 + 1.514 \sqrt{\frac{1^{2}}{37 } + \frac{0.5^{2}}{38 }} )$

CI = (0.422, 0.978)

0.422< mu1 - mu 2 < 0.978

The Cashier

Step-by-step explanation:

First you take off $2.00 of every $18.95 of the game and you get $16.95 you add 16.95 three times and after that you add 11.50 twice and then the sum of both the earbuds and the video games and you add both together and you get $73.85

1. Find four consecutive even integers such that the sum of the first and third is 6 less than the largest

KiRa [710]

1. Let the first integer be represented by: 2k

the second integer by: 2(k+1)

the third integer by: 2(k+2)

and the fourth by: 2(k+3)

Then, 2k + 2(k+2) = 2(k+3) - 6

2k + 2k + 4 = 2k + 6 - 6

4k + 4 = 2k

4 = -2k

-2 = k

Answer: -4, -2, 0, 2

******************************************************************

2. Let the first integer be represented by: 2k+1

the second integer by: 2k+3

the third integer by: 2k+5

and the fourth by: 2k+7

Then, 2k+7 = (2k+1) + (2k+3) + (2k+5) + 2

2k + 7 = 6k + 11

-4 = 4k

-1 = k

Answer: -1, 1, 3, 5
