It can be deduced that the Venn diagram shows the relationship that exist between the light test and the brake test.

It should be noted that a Venn diagram simply means an illustration that uses circles to indicate the relationship among things.

From the information given, the lights test failed on 3 bicycles while 27 bicycles passed the test.

The brake test failed on 9 bicycles while 21 bicycles passed the test. This is depicted in the Venn diagram.

Because it is surface area it would be 800in^2

Using the binomial distribution, it is found that about 75 batteries each day are defective.

For each battery, there are only two possible outcomes, either it is defective, or it is not. The probability of a battery being defective is independent of any other battery, hence the binomial distribution is used to solve this question.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

In this problem:

Then:

[tex]E(X) = np = 500(0.15) = 75[/tex]

About 75 batteries each day are defective.

The marginal cost will most likely increase to $2.00

Marginal cost is the change in the production costs that would be required to make one extra unit of production.

The marginal costs will continue to rise, increasing the total cost, while the marginal revenue remains the same, decreasing the profit.

For example, if a company produces a cup for $5, and 10 cups would be $50, therefore, the marginal cost is the extra cost it would take to manufacture an additional cup.

Hence, the marginal cost will most likely increase to $2.00

To know while working with inequality equations:

- When multiplying or dividing by a negative, you want to flip the direction of the inequality sign. < becomes >, etc

- When graphing, if it is only less/greater than (< or >) the dot will be open

- When graphing, if it is less/greater than and equal too (≤ or ≥) the dot will be closed

- Then, if the x value is on the left side, the arrow will go in the direction of the inequality sign

[3] Divide both sides by -4, flip the sign

-4x ≥ -36

x ≤ 9

[4] Divide both sides by -0.4, flip the sign, and then I flipped the equation to make it easy to graph

3 > -0.4x

-7.5 < x

x > -7.5

[5] Divide both sides by -2.2, flip the sign

-2.2x ≤ -6.6

x ≥ 3

[6] Multiply both sides by -8, flip the sign

[tex]\frac{x}{-8}[/tex] > 2

x < -16

s (t) = 12 - 0.75t

Step-by-step explanation:

Given: The snow started melting at a rate of 0.75 inches per hour and it is known that 4 hours  after the storm ended, after the storm ended, the depth of snow was down to 9 inches.

Snow melted in 4 hours =

Initial depth of snow = 9 + 3 inches = 12 inches.

Now, depth of snow on Tristan's lawn = Initial depth -0.75(Number of hours)

Let S(t) be the depth of snow on Tristan's lawn, in inches, t hours after the snow stopped falling.

Answer:

a.) 10 months

b.) Kool Karate

c.) Karate Klub

Step-by-step explanation:

Karate Klub : y=25x+200

Kool Karate : y=35x+100

A.) First, set the equations equal to each other then solve for x. [tex]A.) 25x+200=35x+100\\\\[/tex]

take away 100 from both sides

[tex]25x+100=35x[/tex]

take away 25x from both sides

[tex]100=10x[/tex]

divide 10 from both sides so x can be by itself and equal to 1

[tex]10=x[/tex]

This means that at 10 months, the cost is the same for both.

B.) Substitute 6 for x in both equations

Karate Klub : [tex]y=25(6)+200\\y=350[/tex]

Kool Karate :[tex]y=35(6)+100\\y=310[/tex]

The cost for Kool Karate is cheaper, so that is what he should join.

C.)  Substitute 12 for x in both equations.

x=12 because there are 12 months in a year.

Karate Klub:[tex]y= 25(12)+200\\y=500[/tex]

Kool Karate:[tex]y=35(12)+100\\y=520[/tex]

The cost for Karate Klub is cheaper, so that is what he should join.

Answer:

x= 3

Step-by-step explanation: I'll assume the problems is

Cross multiply to get:

x2 - 1 = 2x + 2

x2 - 2x - 3 = 0

(x - 3)(x + 1) = 0

x = 3 and x = -1

Test (x = 3):

1/(2•3+2) = 1/(32 - 1)

1/8 = 1/8 true, so x = 3 is a valid solution

Test (for x = -1):

1/(2•(-1)+2) = 1/((-1)2 - 1)

1/0 = 1/0 not true since division by zero is undefined so x = -1 is not a solution (aka, it is extraneous).

To find solutions via graphing, graph y = 1/(2x + 2) and graph y = (x2 - 1) and find the points of intersection. Doing so confirms that the only solution is x = 3.
