Answer:

The mean is equal to 4.

Step-by-step explanation:

To find the mean of any set of numbers, you have to add all of those numbers and divide the result by however many numbers their are.

For example, the mean of 2,5,6, and 7 would be the following: 2+5+6+7/4

The mean of 5,3,6,8,1, and 1 is the following: 5+3+6+8+1+1/6=24/6=4

The mean is equal to 4.

Which equation can be used to find the length of Line segment A C? Triangle A B C is shown. Angle A C B is 90 degrees and angle
taurus [48]

<u><em>Answer:</em></u>

AC = 10sin(40°)

<u><em>Explanation:</em></u>

The diagram representing the question is shown in the attached image

Since the given triangle is a right-angled triangle, we can apply the special trig functions

<u>These functions are as follows:</u>

sin(θ) = opposite / hypotenuse

cos(θ) = adjacent / hypotenuse

tan(θ) = opposite / adjacent

<u>Now, in the given diagram:</u>

θ = 40°

AC is the side opposite to θ

AB = 10 in is the hypotenuse

<u>Based on these givens</u>, we will use the sin(θ) function

<u>Therefore:</u>

sin(40) = \frac{AC}{10}\\ \\AC = 10sin(40)

Fifteen percent of the pigment in paint color A is black. Sixty percent of the pigment in paint color B is black. An unknown amo
Vitek1552 [10]

Answer: 0.15(40) + 0.6(x – 40) = 0.25(x)

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:  

Fifteen percent of the pigment in paint color A is black

15% = 15/100 = 0.15 (decimal form)

0.15 A

Sixty percent of the pigment in paint color B is black

0.6 B

An unknown amount of paint color B is mixed with 40 ml of paint color A,

SO:

0.15 (0.40)  

0.6 (x-0.40)

x = total amount of paint in the mixture of the two colors

The result is a paint that contains 25% (0.25 in decimal form)black pigment (x)

0.15(40) + 0.6(x – 40) = 0.25(x)

Feel free to ask for more if needed or if you did not understand something.
