A company produces computer batteries. Everyday, the company produces exactly 500 batteries. To keep track of how many batteries are defective, a
worker tested a box of batteries. The results are in the table below.
Working Batteries Defective Batteries Total
17
20
Using these results, about how many batteries each day are defective?
O 3
O 25
O75
O425
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.
What is the binomial probability distribution?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:
3 out of 20 batteries are defective, hence p = 3/20 = 0.15.Each day, 500 batteries are produced, hence n = 500.Then:
[tex]E(X) = np = 500(0.15) = 75[/tex]
About 75 batteries each day are defective.

What most likely will happen if the pie maker bakes a seventh pie? The marginal cost will most likely decrease to $1. 00 The marginal cost will most likely increase to $2. 00 The marginal revenue will most likely decrease to $8. 0. The marginal revenue will most likely increase to $12. 0.
The marginal cost will most likely increase to $2.00
What is the marginal cost?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

One day at football practice, Darrell, the kicker, punted the ball so that its height in feet above the ground was given by the following function, where t is the number of seconds since the ball was punted.
[tex]h(t)=-16t^{2} +75[/tex]
When will the football be 81 feet high?
When the football is 81 feet high, it will be √ 3 / 8 seconds
FunctionFunction relates input to output. Therefore,
h(t) = - 16t² + 75Therefore,
t = number of seconds
h(t) = - 16t² + 75
h(t) = 81 ft
Therefore,
81 = - 16t² + 75
- 16t² = 81 - 75
- 16t² = 6
divide both sides by -16
t² = 6 / -16
t² = - 3 / 8
square root both sides
t = √ 3 / 8 seconds

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

At the end of a snow storm, Gavin saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 0.5 inches per hour. Make a table of values and then write an equation for S,S, in terms of t,t, representing the depth of snow on Gavin's lawn, in inches, tt hours after the snow stopped falling.
Answer:
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.
