Gary wanted to determine the average height of boys at the high school. His older brother is on the basketball team, so he asked

him to measure his teammates. After interpreting the results, Gary determined the average height of a high-school-aged boy to be 6 feet, 1 inch. HELP ASAPPPPP
Would you consider these results to be valid?

Yes, because only high-school boys were surveyed.

Yes, because the results were obtained randomly by measuring the boys basketball team.

No, because boys on the basketball team are likely to be taller than the average high school boy.

No, because there are no girls surveyed.

Given the piecewise function. Shown below
creativ13 [48]

Answer:

  (x, g(x)) = {(-2, -2), (0, 0), (2, 2), (4, -3), (6, -3)}

Step-by-step explanation:

The first three values of x in the table are all less than or equal to 2, so the first part of the function definition applies. The y-value is equal to the x-value. The ordered pairs are ...

  (-2, -2), (0, 0), (2, 2)

The last two values of x in the table are more than 2, so the last part of the function definition applies. For those values of x, the y-value is -3. The ordered pairs are ...

  (4, -3), (6, -3)

How do u solve 2x+15=1
pickupchik [31]
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7

A group of artists is selling small prints to raise money for charity. They sell p prints, and make a profit of f(p) on the sale
liraira [26]

The correct answer is is D) If the group sells 15 prints they will loose $85.

To figure out which statement is true, we have to evaluate the function ,

p(x)=17x-340 for all the values given in options (A)-(D).  A negative output represents a loss and  a positive output will represent a profit.

In A p=12 so f(12)=17\times 12-340=-136. In this case we gather that if they sell 12 prints, they will make a loss of $136. This tells us that option A is wrong.

In B, p=28 so f(28)=17\times 28-340=136. In this case we gather that if they sell 28 prints, they make a profit of $136. This tells us that option  B is wrong.

In C, p=35 so f(35)=17\times 35-340=225. In this case we gather that if they sell 35 prints, they make a profit of $225. This tells us that option  C is wrong.

Lastly, p=15 so f(15)=17\times 15-340=-85. In this case we gather that if they sell 28 prints, they make a loss of 85 dollars. From this we gather that D is the correct option.

PLEASE HELP!!
dangina [55]

Answer:

We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.

The excel output is attached here.

Therefore, the equation of the linear regression is:

\hat{y}=21.9028+1.5736x

Where:

21.9028 is the intercept and 1.5736 is the slope.
