Alexa drew AB on a piece of a paper, and then folded the paper so that Point A was on Point B. She claims the crease forms right angles with AB. In two or more complete sentences, explain why Alexa is correct.

Answer:

Proved

Step-by-step explanation:

Given that Alexa drew AB on a piece of a paper, and then folded the paper so that Point A was on Point B.

When Alexa folds the paper the line along the folding forms the line of reflection of A on B.

Now we have AB passing through the line of reflection such that AB cuts the folding line at mid point say C

AC=BC

And also C is right angled by the property of transformation of reflection on a line.

Hence Alexa is correct

She would be right because if you look at it she folded the paper in half, so A was on top of B. And yes it does form right angle it's a lot easier to see if you do it is a little hard to explain~ Sorry

WILL GIVE BRAINLIEST AND 50 POINTS Robin’s scores: 99, 108, 102, 107, 119

Mean = 107; MAD = 5.2

Evelyn’s scores: 125, 137, 138, 145, 145

Mean = 138; MAD = 5.6

Explain what the mean absolute deviation is in general. Explain what the MAD means in the context of Robin and Evelyn’s data.

Answer:

sample response - The MAD describes the average distance from a data point to the mean. It measures variability. For this data, it shows that Evelyn’s scores varied slightly more than Robin’s

Step-by-step explanation:

i took it and hopefully i’ve helped you luvv and stay safe !!! > corona virus

Answer:

Hello, I only know the first part of the question.

Explain what the mean absolute deviation is in general.

The mean absolute deviation of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. In general the mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Hope this helps some :)

rachel , shen & pablo have a total of $63 in their wallets. shen has $5 more than rachel. pablo has 2 times what shen has. how much do they have in their wallets.

Rachel has $12 in wallet

Shen has $17 in wallet

Pablo has $ 34 in wallet

Solution:

Let "r" be the amount in Rachel wallet

Let "s" be the amount in Shen wallet

Let "p" be the amount in Pablo wallet

Given that Rachel and Shen and Pablo have a total of $ 63 in their wallets

We can frame a equation as:

amount in Rachel wallet + amount in Shen wallet + amount in Pablo wallet = $63

r + s + p = 63 ----- eqn 1

Shen has $5 more than Rachel

amount in Shen wallet = 5 + amount in Rachel wallet

s = 5 + r ----- eqn 2

Pablo has 2 times what Shen has

Amount in Pablo wallet = 2 x amount in Shen wallet

p = 2s ---- eqn 3

Let us solve eqn 1 and eqn 2 and eqn 3 to find values of "s" "r" and "p"

From eqn 2,

r = s - 5 ----- eqn 4

Substitute eqn 4, eqn 3 in eqn 1

s - 5 + s + 2s = 63

4s - 5 = 63

4s = 68

s = 17Substitute s = 17 in eqn 4

r = s - 5 = 17 - 5 = 12

r = 12Substitute s = 17 in eqn 3

p = 2(17) = 34

p = 34Thus we have:

Rachel has $12 in wallet

Shen has $17 in wallet

Pablo has $ 34 in wallet
