Answer:

The x and y are not proportional.

2 | $\frac{5}{2}$

3 | $\frac{5}{2}$

6 | $\frac{5}{2}$

Step-by-step explanation:

The equation has a 0 slope, so the y-value is always 5/2.

Answer:

The correct answer would be C

Step-by-step explanation:

Looking at the data, you can tell that the first two are going to be wrong. The minimum is 1, and the maximum is 5.

A mode, by definition, is the number that appears most in the data. According to answer D, 3 appears 3 times in the data. That is incorrect, as 3 only appears twice in the data.

This leaves only answer C. We need to make sure it's correct. The answer mentions the mean as a value between 2 and 3. Mean is the average. To find the average, you must add all the values together first.

1 + 2 + 5 + 3 + 2 + 2 + 5 + 3 = 23

Then, you must divide the value by the number of data given. There are 8 numbers here, so you must divide 23 by 8.

23/8 = 2.875

2.875 is between the numbers 2 and 3 like answer C said, so C is correct.

John typed a 48 word paragraph in 2/3 minute. What is the typing speed in words per minute

serg [7]

Answer: The answer is: " 72 words per minute. "

___________________________

Step-by-step explanation:

___________________________

This is a "unit rate" problem.

We want to solve for/ find the number of words PER single minute.

___________________________

Given 48 words per (2/3) minute;

How many words per (one) minute?

__________________________

The answer is {48 ÷ (2/3) } words per minute:

Note: dividing by a number is the same as multiplying by the reciprocal (inverse) of that particular number:

Hence:

__________________________

The answer is {48 * (3/2) } words per minute:

__________________________

Write as:

" $\frac{48}{1} *\frac{3}{2}$ " ;

__________________________

The "48" can be changed to "24" ; and the "2" can be changed to "1" ;

→ {Since: "48 ÷ 2 = 24 "} ;

___________________________

And we have:

___________________________

" $\frac{24}{1} *\frac{3}{1} = 24 * 3 = 72$ " ;

___________________________

The answer is: " 72 words per minute ."

___________________________

Hope this is helpful to you!

A snail crawls 2 3/4 inches in one minute . How far can it travel in 3 1/2 minutes?

Luden [163]

Answer: 5/6 inch/minute

Whenever you are working with a question of rate where two different quantities are being compared, the required units will indicate which quantity is to be divided by which.

In this case you want to know inches per minute.Therefore:

inches

minute

←

multiply by the reciprocal

The system of inequalities is:

y ≤ -0.05*x^2 + 6x

y > 1.5x + 45

(30, 90) is not a solution of that system, while (60, 160) is a solution.

<h3>How to get the system of inequalities?</h3>

We know that the revenue y is given by:

y ≤ -0.05x^2 + 6x

And we know that the costs are 1.5x + 45, and the revenue must be larger than that, so we also have the inequality:

y > 1.5x + 45

So the system is:

y ≤ -0.05*x^2 + 6x

y > 1.5x + 45

Now, the point (30, 90) means that we need to replace x by 30 and y by 90, replacing that in the second inequality, we will get:

90 > 1.5*30 + 45 = 90

90 > 90

This is false, so the point is not a solution of this inequality, meaning that the point is not a solution of the system.

For the second point we do the same: x= 60, y = 160, replacing that in the second inequality we get:

160 > 1.5*60 + 45 = 135

160 > 135

This is true, now we need to check with the other inequality.

160 ≤ -0.05*60^2 + 6*60 = 180

This is also true.

So the point (60, 160) is a solution to the system.
