Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40


1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

Find x if f(x) = 2x + 7 and f(x) = -1.

Answers

Answer:  The required value of x is -4.

Step-by-step explanation:  We are given to find the value of x if :

f(x)=2x+7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\n\nf(x)=-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)

Since both the equations (i) and (ii) are the values of x, so comparing the equations, we get

2x+7=-1\n\n\Rightarrow 2x=-1-7\n\n\Rightarrow 2x=-8\n\n\Rightarrow x=-(8)/(2)\n\n\Rightarrow x=-4.

Thus, the required value of x is -4.

f(x) = 2x+7

-1 = 2x+7
-7        -7

-8 = 2x

-8/2 = 2x/2

-4 = x

x = -4

A container at a paper clip factory holds 2.1*10^3 pounds of paper clips. There are 9.6*10^5 paper clips in the container. Find the approximate weight of each paper clip in ounces. (1 pound= 16 ounces) Show Your Work.

Answers

Answer:

The approximate weight of each paper clip is 0.035 ounce.

Step-by-step explanation:

A container at a paper clip factory holds 2.1*10^3 pounds of paper clips.

= 2.1*1000=2100 pounds

There are 9.6*10^5 paper clips in the container.

= 9.6*100000=960000

Now we get that 960000 paper clips weigh 2100 pounds.

So, each paper clip will weigh = (2100)/(960000) = 0.0021875 pounds

And 1 pound = 16 ounces

0.0021875 pounds = 16*0.0021875 = 0.035 ounce

Hence, the approximate weight of each paper clip is 0.035 ounce.

Divide the total weight (2.1 * 10^3 lbs.) by the total quantity of things (9.6 * 10^5) to get the lbs./paperclip. 

Then, multiply that number by 16 to get ounces/paperclip.

The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations.What is the survey’s margin of error?

Answers

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The margin of error of the survey will be ±4%.

What is the margin of error?

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations. Therefore, the margin of error can be written as,

Margin of Error = (84%-76%)/2 = 8%/2 = ±4%

Hence, the margin of error of the survey will be ±4%.

Answer:

±4

Step-by-step explanation:

The margin of error in a confidence interval is half the range:

(84 - 76) / 2 = 4

So the margin of error is ±4.
