F(1)=8000x0.55x1=4400
f(2)=8000x0.55x2=8800
(8800-4400)/2=2200

Answer:

x = 63 y = 27

Step-by-step explanation:

The straight line is 180 degrees

subtract 117 from 180 to get 63

It says x+7= 90, so subtract x(63) from 90 to get 27

A computer generates 80 integers from 1 to 5 at random. The results are recorded in the table. What is the experimental probabil

matrenka [14]

The experimental probability of the computer generating a 2 is 20%.

<h3>What is the experimental probability?</h3>

The experimental probability determines the odds an event would happen based on the results of an experiment.

Experimental probability = ( number of times a 2 was generated / total number of numbers generated) x 100

(16 / 80) x 100 = 20%

Greetings!

Substitute:
$x+y=1000 \\ x=1000-y$
Now we can input this into the other equation so, we only have one variable.

Solve for y.
$0.05(1000-y)+0.06y=57$
Distribute the parenthesis.
$50-0.05y+0.06y=57$
Combine Like Terms.
$50-0.01y=57$
Add -50 to both sides.
$(50-0.01y)+(-50)=(57)+(-50)$
Simplify.
$0.01y=7$
Divide both sides by 0.01.
$(0.01y)/0.01=(7)/0.01$
Simplify.
$y=700$

Input this value into the other equation.
$x+700=1000$
Add -700 to both sides.
$(x+700)+(-700)=(1000)+(-700)$
Simplify.
$x=300$

The answer would be 300,700

Hope this helps.
