Given polynomial

           p(x)=7x³ -6x²+39x-104

Put x=-1

          p (-1)    = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104

                     = - 7 - 6 - 39 - 104

A theater is filled with 84 females and 132 males. What percent of the people in the theater are female?

Answers

Answer:

look at how I rounded them and put in the answer it says to round to

Step-by-step explanation:

84 + 132 = 216

84 / 216 = 38.88%

rounded to the nearest hundredth = 38.89%

rounded to the nearest tenth = 38.9%

rounded to the nearest whole number = 39%

The percent of the people in the theater are female will be 38.89%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A theater is filled with 84 females and 132 males.

Now,

Since, A theater is filled with 84 females and 132 males.

Hence, Total number of peoples = 84 + 132

                                                   = 216

Thus, The percent of the people in the theater are female will be;

Percent = 84 x 100 / 216

            = 38.89%

Therefore, The percent of the people in the theater are female will be 38.89%.

2.1      Solve :    -9   =  0

This equation has no solution.

The best player on a basketball team makes 95​% of all free throws. The​ second-best player makes 90​% of all free throws. The​ third-best player makes 80​% of all free throws. Based on their experimental​ probabilities, estimate the number of free throws each player will make in his or her next 40 attempts. Explain.

Answers

Answer: See explanation

Step-by-step explanation:

The best player on a basketball team makes 95​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 95% × 40

= 95/100 × 40

= 0.95 × 40

= 38

The​ second-best player makes 90​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 90% × 40

= 90/100 × 40

= 0.90 × 40

= 36

The​ third-best player makes 80​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 80% × 40

= 80/100 × 40

= 0.80 × 40

= 32

Answer:

RS = 11

Step-by-step explanation:

well from the mid-point theorem we have that

[tex]\triangle PRS \sim \triangle PNQ[/tex]

by a ratio of

[tex]1:2[/tex]

so

[tex]\frac{RS}{NQ}=\frac{1}{2}\\\\2[\frac{RS}{NQ}]=2[\frac{1}{2}]\\\\\frac{2RS}{NQ}=1\\\\NQ[\frac{2RS}{NQ}]=NQ[1]\\\\2RS=NQ[/tex]

and now we plug in

[tex]RS = 5x-39\\\\NQ = 4x-18[/tex]

[tex]2[5x-39]=4x-18\\\\10x-78=4x-18\\\\10x-4x=-18+78\\\\6x=60\\\\x=10[/tex]

so the length of RS is

[tex]RS = 5x-39\\\\RS = 5(10)-39\\\\RS=50-39\\\\RS=11[/tex]

A regular m-gon has 3 times as many sides as a regular k-gon.
The measure of an interior angle of the regular m-gon is 14/3 times
the measure of an exterior angle of the regular k-gon.
Algebraically find the values of k and m.

Answers

9514 1404 393

Answer:

k = 10m = 30

Step-by-step explanation:

The interior angle of the m-gon is ...

  m-interior = 180 -360/m

The exterior angle of the k-gon is ...

  k-exterior = 360/k

The required relationships are ...

  m = 3k

  m-interior = 14/3(k-exterior)

Substituting for m, we can write the latter relation as ...

  (180 -360/(3k)) = 14/3(360/k)

Multiplying by 3k/180, we have ...

  3k -2 = 28

  k = (28 +2)/3 = 10

The values of k and m are 10 and 30, respectively.

_____

Check

The interior angle of the m-gon is 180 -360/30 = 168 degrees.

The exterior angle of the k-gon is 360/10 = 36 degrees.

The angle ratio is 168/36 = 14/3 as required.
