Answer:

106

Step-by-step explanation:

Substitute x = 3 into f(x) and evaluate , that is

f(3)

= 10(3)² + 6(3) - 2 = 10(9) + 18 - 2 = 90 + 18 - 2 = 106

The two box plots summarize the number of hours spent in the weight room for all the players on the football team
iragen [17]

Options:

A. Players at school 1 typically spent more time in the weight room than players at school 2.

B. The middle half of the data for school 1 has more variability than the middle half of the data for school 2.

C. The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both schools are equal.

D. The total number of hours spent in the weight room for players at school 2 is greater than the total number of hours for players at school 1.

(See attachment for the box plots)

Answer:

C. The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both schools are equal.

Step-by-step explanation:

The median for school 1 is the value at the vertical line that divides the box of the box plot display of for school 1, which is 8

School 2 has a median of 9.

As we can see, the median for school 1 is less than the median of school 2.

Interquartile range is the range of the box.

Interquartile range for school 1 = 10 - 4 = 6

Interquartile range for school 2 = 13 - 6 = 6

As we can also see, the interquartile range for school 1 and that of school 2 are equal.

Solve the equation, if possible. (If all real numbers are solutions, enter REALS. If there is no solution, enter NO SOLUTION.)
Masteriza [31]

Answer:

The equation x\left(x\:+\:6\right)\:=\:\left(x\:+\:3\right)^2 has NO SOLUTION, and is called contradiction.

Step-by-step explanation:

Given the equation

x\left(x\:+\:6\right)\:=\:\left(x\:+\:3\right)^2

\mathrm{Expand\:}x\left(x+6\right):\quad x^2+6x

\mathrm{Expand\:}\left(x+3\right)^2:\quad x^2+6x+9

so

x^2+6x=x^2+6x+9

\mathrm{Subtract\:}x^2+6x\mathrm{\:from\:both\:sides}

x^2+6x-\left(x^2+6x\right)=x^2+6x+9-\left(x^2+6x\right)

\mathrm{Simplify}

0=9

\mathrm{The\:sides\:are\:not\:equal}

Thus, there is NO SOLUTION.

  • We know that an equation that has no solution, such as x = x + 2, is called a contradiction.

Therefore, the equation x\left(x\:+\:6\right)\:=\:\left(x\:+\:3\right)^2 has NO SOLUTION, and is called contradiction.
