Answer:

third choice

Step-by-step explanation:

commutative property of addition

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.

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 $).

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).

Answer:

Thus the answer is 127

Step-by-step explanation:

4 feet = 48 inches. 2.54 = 1 inch.

It is found that Joan's  height is 127 centimetres.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Joan is 4 feet 2 inches tall and we need to change to centimeters .

First we change her height to inches;

1 Foot = 12 Inches

Therefore, 4 Feet = 4 x 12 = 48 inches

The Total height in inches =48 inches + 2 Inches = 50 inches

Now, we have gotten her height in inches, change  to centimetres.

We have that;

1  inch =2.54 centimeters

50inches = 50 x 2.54 cm

=127 centmeters.

Hence, Joan's height is 127 centimetres.

Answer:

These ratios are not equivalent.

Step-by-step explanation:

If you get 5 pairs of socks for $15, that means that each pair of socks are $3. If you buy 10 pairs of socks for $25, you are spending $12.50 for each pair. If you double the 5 pairs of socks for 10 pairs of socks, you will be spending $30 because you have to add another $15.

So between 10 pairs of socks for $30 (5 pairs of socks for $15) and 10 pairs of socks for $25, you will be spending more on the 5 pairs of socks.

You are spending more money on the 5 pairs of socks for $15.

(b) x = 13/3

Step-by-step explanation:

Step 1: Define

f(x) = 3x + 2

(a) f(7) is x = 7

(b) f(x) = 15

Step 2: Substitute and Evaluate

(a) f(7) = 3(7) + 2

f(7) = 21 + 2

f(7) = 23

(b) 15 = 3x + 2

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!
