Answer:

Step-by-step explanation:

Given

8 - 2x + 6x = 24 , that is

8 + 4x = 24 ( subtract 8 from both sides )

4x = 16 ( divide both sides by 4 )

x = 4 → A

First, let's find out how much the 6 boxes weigh. If one box of clay weighs 17.4 ounces, then how much does 6 boxes weigh? Well, let's multiply.

17.4 × 6 = 104.4

Next, let's find out how much clay each student get. Since there are 18 students and only 6 boxes, let's find this out by dividing the ounces.

104.4 ÷ 18 = 5.8

So, each student gets 5.8 ounces of clay. I hope this helps!

Correct answers:

$\left(241.42,\ 262.14\right)$

A 95% confidence interval for μ is (x¯−zα/2σn‾√,x¯+zα/2σn‾√). Here, α=0.05, σ=37, and n=49. Use Excel to calculate the 95% confidence interval.

1. Open Excel, enter the given data in column A, and find the sample mean, x¯, using the AVERAGE function. Thus, the sample mean, rounded to two decimal places, is x¯=251.78.

2. Click on any empty cell, enter =CONFIDENCE.NORM(0.05,37,49), and press ENTER.

3. The margin of error, rounded to two decimal places, is zα/2σn‾√≈10.36. The confidence interval for the population mean has a lower limit of 251.78−10.36=241.42 and an upper limit of 251.78+10.36=262.14.

Thus, the 95% confidence interval for μ is (241.42, 262.14).

Please solve quickly

Step-by-step explanation:

first you need to find the height

V = L×W×H

the volume your given is 880mm³

length is 22mm

width is 8mm

height is unknown

furthermore

V=L×W×H

880mm³= 22mm×8mm×H

880mm³= 176mm²×H

880mm³/176mm²=176mm²/176mm²×H

5mm=H

H=5mm

<h3>Surface Area= S.A</h3>

therefore S.A=2(L×W+ W×H +L×H)

=2(22mm×8mm+8mm×5mm+22mm×5mm)

=2(176mm²+40mm²+ 110mm²)

=352mm²+80mm²+220mm²

=652mm²

What is the area of this figure?

scoundrel [369]

The answer would be <u>189 cm²</u>. Multiply the legs of the triangle (12 x 9), and keep that answer. Usually, to measure the area of a triangle, you would multiply the legs and divide by 2, but since there are two congruent triangles in the same shape here, you don't have to. Next step would be to add the area of the square in the middle (9 x 9). Add 12x9 to 9x9 (108 + 81) to get 189.

Hope this helps! If it did, would my mind marking my answer as Brainliest? Thanks :D
