Answer:

x = 7

Step-by-step explanation:

<u>Distribute </u>-

12x − 66 + 15 = 3x + 12

<u>Combine Numbers and Variables</u> -

12x - 51 = 3x +12

<u>Get x on one side (isolate x)</u> -

9x - 51 = 12

9x = 63

<u>Divide 9</u> -

x =7

Which of the following statements must be true about the diagram? Check all that apply.
Ray Of Light [21]

Answer:

x + y = w

w > x

w > y

Step-by-step explanation:

x and y are interior angles of a triangle.

w is the exterior angle ( opposite to angles x and y ) of a triangle.

There is a formula that exterior angle of a triangle is equal to sum of two interior angles of a triangle.

So,

x + y = w

If x + y = w,

Then,

w > x

w > y

Lincoln told his mother that 4 5/10
Sveta_85 [38]

Answer:

4.5

Step-by-step explanation:

In order to find the answer to this question you will first need to convert Lincolns height into a improper fraction and then convert the improper fraction into a decimal number.

L =4\frac{5}{10}

Convert into improper fraction

4\frac{5}{10} =10 \times4=40+5=45=\frac{45}{10}

Convert into decimal by dividing the numerator by the denominator:

45\div10=4.5

L=4.5

Hope this helps.

<h3>Answer: B)  2.9  approximately</h3>

==================================================

Explanation:

The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the (x-\overline{x})^2 terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so \sum(x-\overline{x})^2 = 34

From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list

So,

s = \sqrt{\frac{1}{n-1}\sum(x-\overline{x})^2} \\\\s = \sqrt{\frac{1}{5-1}*34} \\\\s = \sqrt{\frac{1}{4}*34} \\\\s = \sqrt{0.25*34} \\\\s = \sqrt{8.5} \\\\s \approx 2.91547594742266 \\\\s \approx 2.9 \\\\

This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.
