We know that a line of best fit is a straight line drawn for a given data which may or may not pass through data points.

It is given that the line is drawn for 7 data points. Hence, the line may or may not pass through all these 7 points.

Therefore, the maximum number of data points that may not actually be on the line is 7.

Answer:

20 + 2x = 4x

Step-by-step explanation:

So you are setting the two expressions equal to each other.

buying a membership card  and paying each time looks like this: 20 + 2x where x is the number of times you go to the gym.  20 dollars base then 2 each time you go.

4 each time you go is just 4x

so just set the two equal to each other.

20 + 2x = 4x

If you solve it you will get x = something, which would be the number of times to make the two equal.

The radius of a circle is 15 inches. A chord is drawn 4 inches from the center of the circle. How long is the chord?
Alex73 [517]

Let X represent the length of the chord.

By using Pythagoras' Theorem:

4^2 + (X/2)^2 = 15^2

(X^2)/4 = 209

X^2 = 836

X = 28.91

a taco stand sells tacos for $3.25 each. the stand's expenses for the day are $210. definec your variables and write an inequali
AlekseyPX

Okay, we know that the expenses for the day is 210.

Knowing this, and the price of the taco, we write the inequality:

3.25t > 210

t = number of tacos

Now divide both sides by 3.25:

t > 64.62 (rounded)

Because a taco stand can't sell a fraction of a taco, we know that the taco stand has to sell more than 65 tacos for a profit.
