Luden [163]

Answer:

25%

Step-by-step explanation:

There is 20 men total, at least 5 will say no .

So you get a fraction : 5/20.

You  divide both the nominator and denominator by 5 (bc 5 goes into 20).

So you end up with 1/4.

Convert 1/4 to a percent and you get .25 or 25%.

Hope this helps ((:

Solve the system of equations.
REY [17]

Answer:

D

Step-by-step explanation:     Time Stamp (6  9  10  32)

Easiest way is to graph both equation and look for the intersections  see attached sreen shot

or  solve by substitution

y = 2x

y = x²- 8

2x = x²- 8                  solve for x

0  = x² - 2x - 8          factor

0 = (x - 4)(x + 2)

0 = 0   when x = 4 and -2      

calculate the y values

y = 2x      x = 4

y = 8                              (4, 8)

y = 2x      x = -2

y = -4                            (-2, -4)

Question 1(Multiple Choice Worth 3 points)
KonstantinChe [14]

Answer:

O The value of x is less than 16.

Step-by-step explanation:

Do the actual work:  solve for x:

Divide both sides by 107.06:

          16

x < -------------- = 0.149    This does not agree well with any of your answer

       107.06                     choices.  If I had to choose one answer, it'd be the                  

                                        first one, since "the value of x is less than 16" is

                                        certainly true.
