Answer:
The answer is D: To know on which book, number of words is more between, Computer Science and Math
Magdeline selects 25 pages from each book, then Calculates Mean, Median, Mean Absolute Deviation of number of words on each page.
Book Mean Median Mean Absolute Deviation
Computer science 48.7 40 9.4
Math 34.2 45 1.9
Observing what Magdeline has Done,
Mean is Sum of words on each page of 25 pages divided by 25.
1. Mean of Computer Science book is more than mean number of words on pages of math book.
2.And, Median means , computer science book has more pages which contains 40 words ,and Math book has more pages which contain 45 words.
3.Now,Coming to Mean Absolute Deviation, which measures the Variability from Mean.
In computer science book ,there is more Variability that is, 9.4 and 1.9 in math book.
So, just by claiming, that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page appears invalid Inference, because variability from mean in computer science book is more than variability from mean in Math book because Mean Absolute Deviation measures Variability fro mean.
A rectangle has its diagonal length increased from 5 cm to 25 cm. The new rectangle is similar to the original one. The original perimeter was 14 cm. What is the measure of the new perimeter?
Answer:
The measure of the new perimeter is 70cm.
Step-by-step explanation:
I thought putting up a picture would be easier than explaining it all. The picture is how you would write out the problem.
The original rectangle's measures were 5cm and 14cm. The new rectangles measures are 25 cm and X (We don't know yet.) So write it out. 5cm is to 14cm as 25cm is to X.
5cm/14cm = 25cm/X
Cross multiply. (The arrows I drew. Multiply diagonally.)
You should get
350 = 5X
We need to get X by itself, so divide both sides by 5.
5X/5 leaves X left
350/5 leaves 70
70 = X

Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more.
Dario and another person scuba diving. The other person is diving at negative thirty feet.
A number line from negative fifty to fifty by tens is shown.
After the descent, what was his elevation in relation to another diver at an elevation of −30 feet?
Do the equation
Answer:
keep reading
Step-by-step explanation:
Well... Dario is at -40 feet. So the difference would be 10 feet. I don't really know how you would write that equation. But I hope this helped.
The elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more. Another diver is diving at -30 feet.
The elevation will be calculated as below:-
Elevation = -30 - ( -40 )
Elevation = -30 + 40
Elevation = 10 feet
Therefore, the elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.

In a bag of gumballs, 50% of the gumballs are blue. There are 40 blue gumballs in the bag. How many total gumballs are in the bag?
80
58
200
42
Answer:
80
Step-by-step explanation:
40*2=80
Answer:
It is 80.
Step-by-step explanation:
50% is half and there are 40 blue gumballs in the bag. If you wanted to know the total, you would double 40 because 40 is 50% of the bag, so you are just adding half of it in to get the whole. When you double it, you get 80.

Step-by-step explanation:
Answer: F.) $404.17
Explanation: To solve this, first you'd need to subtract the payments people will be making towards the cost. Since the grandparents will be paying half, you need to divide the $19,700 ÷ 2. The quotient of this is $9,850. Because $9,850 is half of the total cost, we are now left with the other $9,850. Luckily, the student's athletic scholarship will be subtracting $5,000 from the total. And so, after subtracting $9,850 - $5,000, we get a difference of $4850. $4850 is the amount that the student pays over the course of 12 months. To calculate how much she needs to save every month, we will divide 4850 ÷ 12 and receive a quotient of 404.17. Therefore, the student will need to save $404.17 every month in order to pay off the remaining costs at the end of the 12 months.

Danielle makes $20 per week, and she already has $50. Write an equation to find y, the amount of money Danielle has after x weeks.
Answer:
50 + 20x = y
(you should get a second opinion)
Answer:
y=20x+50
Step-by-step explanation:
In slope-intercept form y=mx+b,
y is determined after the x value is plugged in
m is the slope (in this case it's 20)
x is the value you plugin
and b is the y-intercept; this value does not change
put it all together and you get y=20x+50
