The graph shows the number of quarts picked and the amount of money the customer paid.

Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?

Answers

Answer:

$3.50 for 1 quart

Step-by-step explanation:

Point (n, a) on the graph represents the number of quarts and the Amount paid(in $).

What is the importance of graphs in our daily life?

Graphs are a popular tool for visually illuminating data relationships. A graph serves the objective of presenting data that are either too many or complex to be fully expressed in the text while taking up less room.

Given, The graph shows the number of quarts picked and the amount of money the customer paid. Another customer pays $8.75 for the strawberries she picks.

Slope of the given graph  = y₂ - y₁ / x₂ - x₁

Slope of the given graph  = 3.5-0 /1-0 = 3.5

As the Graph is passing through the origin point

Hence, the equation of the line will be y = mx

Where slope(m) = 3.5

thus the equation of the given graph  y = 3.5 x

For another customer given, y = 8.75

Hence x = 8.75/3.5

x = 2.5

Coordinates over the graph will be(2.5, 8.75)

Therefore, The number of quarts and the amount paid (in dollars) are represented by the graph's points (n, a).

The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.

How many gallons of water will the dishwasher use to wash 12 loads of dishes?

Answers

Answer:

I believe it 96.

Step-by-step explanation:

32÷4=8

4×8=32

12×8=96

Answer:

96 gallons

Step-by-step explanation:

So to wash 4 loads of dishes, you need 32 gallons.  If you divide 32 by 4 you get 8.  That means you need 8 gallons of water per load.  Since there are 12 loads and you need 8 gallons per load, if you multiply 8 X 12 you get 96.  This means you need 96 gallons of water for 12 loads of dishes.  Hope it helps!

Magdeline wants to know if the number of words on a page in her computer science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.

Book Mean Median Mean Absolute Deviation
Computer science 48.7 40 9.4
Math 34.2 45 1.9


She claims 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. Based on the data, is this a valid inference? (10 points)
Group of answer choices

Yes, because there is a lot of variability in the computer science book data

Yes, because the mean is larger in the computer science book

No, because the mean is larger in the computer science book

No, because there is a lot of variability in the computer science book data (brainliest if its right)

Answers

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.
