Can someone help please? Fill in the missing number √□=14

Elena-2011 [213]

For the square root of a number to be a whole number, we would need to have a perfect square. 14 is given to us, so to find the missing number, all we have to do is square 14 (or multiply it by itself).

14 x 14 = 196

The missing number is 196.

Hope this helps! :)

You have a job filling cylinder-shaped tubes with flavored sugar. Your boss asks you to find the volume of a tube that is 21 inc

Finger [1]

To find the volume of the tube you will use the formula for finding the volume of a cylinder.

V = pi x r^2 x h
3.14 x 0.5^2 x 21
V = 16.485 cubic inches

The approximate volume of the tube is 16.49 cubic inches.

Suppose that we have collected a sample of 8 observations with values 12.6, 12.9, 13.4, 12.3, 13.6, 13.5, 12.6, and 13.1. What a

Korolek [52]

Answer:

The sample mean is 13.

The sample variance is 0.2286.

The sample standard deviation is 0.4781.

Step-by-step explanation:

The sample is:

S = {12.6, 12.9, 13.4, 12.3, 13.6, 13.5, 12.6, 13.1}

The sample is of size n = 8.

The formula to compute the sample mean, sample variance and sample standard deviation are:

$\bar x=\frac{1}{n} \sum x$

$s^{2}=\frac{1}{n}\sum (x-\bar x)^{2} \\s=\sqrt{\frac{1}{n}\sum (x-\bar x)^{2} }\\$

Compute the sample mean as follows:

$\bar x=\frac{1}{n} \sum x\\=\frac{1}{8}(12.6+ 12.9+ 13.4+ 12.3+ 13.6+ 13.5+ 12.6+ 13.1)\\=\frac{104}{8}\\ =13$

The sample mean is 13.

Compute the sample variance as follows:

$s^{2}=\frac{1}{n-1}\sum (x-\bar x)^{2} \\=\frac{1}{8-1}[(12.6-13)^{2}+(12.9-13)^{2}+(13.4-13)^{2}+...+(13.1-13)^{2}] \\=\frac{1}{7}\times1.6\\=0.2286$

The sample variance is 0.2286.

Compute the sample standard deviation as follows:

$s=\sqrt{s^{2}}\\=\sqrt{0.2286}\\=0.4781$

The sample standard deviation is 0.4781.

Solve for x; x: 6 = 54: 162 A. 1 B. 2 C. 3 D. 4 find x

Gemiola [76]

Answer:

x = 2

Step-by-step explanation:

x:6 = 54:162

What is 54 to 162?

162/54 = 3.

So x times 3 should equal 6.

6/3 = 2.

x = 2

Let's confirm,

2:6 = 54:162
