<span>Mean absolute deviation around the mean

</span>Mean for set 1 equals:  (20+24+40+63+76+89)/6 = 312/6 = 52
Mean for set 2 equals:  (41+50+58+62+72+83)/6 = 366/6 = 61

Mean absolute deviation around the mean for set 1 equals:
( |20 - 52| + |24 - 52| + |40 - 52| + |63 - 52| + |76 - 52| + |89 - 52| )/6 = (32 + 28 + 12 + 11 + 24 + 37)/6 = 144/6 = 24

Mean absolute deviation around the mean for set 2 equals:<span>
</span>( |41 - 61| + |50 - 61| + |58 - 61| + |62 - 61| + |72 - 61| + |83 - 61| )/6 = (20 + 11 + 3 + 1 + 11 + 22)/6 = 68/6 = 11,334

Triangle LMN is a right triangle, and angles L and N are equal. What is the measure of angle L?​
Lilit [14]

Answer:

45 degrees

Step-by-step explanation:

OK so

is L and N are equal you can represent that as 2x

the remaining angle should be 90 because right triangles always have a 90 degrees angle somewhere

you know that all three angles of a triangle add up to 180 so that's what the total is

2x+90=180

subtract 90 from both sides

2x=90

divide both sides by 2

x=45

Lisa and Bill made 60 magnets for a craft fair. They sold about 55% of the magnets. Lisa says they sold about 30 magnets. Bill s
koban [17]

Answer:

Step-by-step explanation:

The total number of magnets that Lisa and Bill made for the craft fair is 60.

They sold about 55% of the magnets. The number of magnets that they sold would be about

55/100 × 60 = 0.55 × 60 = 33

If Lisa says that they sold about 30 magnets, she is correct because if we round off 33 to the nearest ten, it would be 30 magnets.

If Bill says that they sold about 36 magnets, he is wrong because if we round off 36 to the nearest ten, it would be 40 magnets.

41 + 26 + 9 + 14 + 10

67 + 9 + 14 + 10

76 + 14 + 10

What is the meaning of an absolute value
storchak [24]

Answer:

"Absolute value" is the non-negative value of a number, disregarding whether or not it has a sign.

Step-by-step explanation:

"Absolute value" is the non-negative value of a number, disregarding whether or not it has a sign. It can be thought of as how far it is away from the number of 0, whether it's to the left or right. Absolute value of a number is written as |x|, where x = any number. Let's say x was -1. |-1| would be 1 because it's 1 away from 0. If x was just 1, then the number would stay the same.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
