Answer:
A. The mean will increase.
Step-by-step explanation:
The mean is the average of the numbers. You just add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
84 + 75 + 76 + 80 + 48 + 75 = 438
438 / 6 = 73
mean = 73
The outlier is 48, so when you remove it, there will now be only five numbers in the set, and the mean will increase in size.
84 + 75 + 76 + 80 + 75 = 390
390 / 5 = 78
NEW mean (without the outlier) : 78
<u>Answer: </u><em><u>h=80 is the final answer. *The answer must be have a positive sign.*</u></em>
Explanation:
<em><u>Switch sides of an equation.</u></em>
<em><u>3/4h=60</u></em>
<em><u>multiply by 4 both sides of an equation.</u></em>
<em><u>4*3/4h=60*4</u></em>
<em><u>simplify.</u></em>
<em><u>3h=240</u></em>
<em><u>divide by 3 both sides of an equation.</u></em>
<em><u>3h/3=240/3</u></em>
<em><u>simplify.</u></em>
<em><u>240/3=80</u></em>
<em><u>80*3=240</u></em>
<em><u>3*80=240</u></em>
<em><u>240/80=3</u></em>
<em><u>h=80</u></em>
<em><u>Hope this helps!</u></em>
<em><u>Thanks!</u></em>
<em><u>Have a great day!</u></em>
Answer:
33
Step-by-step explanation:
So the angle of 40 is a vertical angle with the one opposite of it, meaning that the triangle on the left would have two values of 40 and 41, to find the value of the 3rd angle of the left triangle, you can subtract 40 and 41 from 180 which is the total number of degrees in a triangle to get 99, then you can find the degrees of the triangle on the right's bottom angle by subtracting 99 from 180, meaning the bottom left angle would be 81, then you can do the same to find the other angle by subtracting 114 from 180 to get 66. Lastly you can add 81 and 66 to get 147, then subtracting 147 from 180 you would get x=33
