Find the greatest common factor of 36 and 54

8090 [49]

Hey there!

To find the greatest common factor you will need to find all the factors of 36 and 54. (A factor is a number that can be divided into another number).

54 - 1, 2, 3, 6, 9, 18, 27.

36 - 1, 2, 3, 4, 6, 9, 12, 18.

As you can see here, the factor that is the greatest is 18. Therefore, that is your answer.

Hope this helps! :)

What is the volume of this container?

Keith_Richards [23]

Answer:

The volume of the container is $56\ in^{3}$

Step-by-step explanation:

we know that

The volume of the figure is equal to

$V=Bh$

where

B is the area of the base

h is the height of the figure

Let

$h=4\ in$

Find the area of the base B

$B=(4*4)-(1*2)=14\ in^{2}$

substitute

$V=14*4=56\ in^{3}$

slavikrds [6]

Answer:

21

Step-by-step explanation:

Using<em> Simple Random Sampling</em>, we can estimate the sample size by the formula

$\bf n=\frac{Z^2S^2}{e^2}$

where

n = sample size

Z = the z-score corresponding to the confidence level 99.5%

S = the assumed standard deviation = 3 seconds

e = margin of error = 2 seconds

<em>It is worth noticing that the higher the confidence level, the larger the sample should be. </em>

The z-score corresponding to a confidence level of 99.5% can be obtained either with a table or the computer and equals

Z = 3.023

Replacing the values in our formula

$\bf n=\frac{(3.023)^23^2}{2^2}=20.5616\approx 21$

So the size of the sample should be at least 21.

yulyashka [42]

Answer:

B and E

Step-by-step explanation:

A. -7 ÷ (-4) = -7/-4 = 7/4 = 1.75

B. -(3 ÷ 2) = -(1.5) = -1.5

C. -8/5 * (-5/8) = (8/5) * (5/8) = 1

D. -5/-3 = 5/3 ≈ 1.667

E. -9 ÷ 6 = -9/6 = -1.5
