When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select and test 42 batteries and determine whether each is within specifications. The entire shipment is accepted if at most 2 batteries do not meet specifications. A shipment contains 7000 batteries, and 2% of them do not meet specifications. What is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected? The probability that this whole shipment will be accepted is (Round to four decimal places as needed.) The company will accept % of the shipments and will reject % of the shipments, so (Round to two decimal places as needed.)
Answers
Solution
Here, we would calculate the probability that one is defective, two are defective, three are defective and the probability that none are defective and sum them together.
The probability that any individual battery is not defective = 1 - 2% = 0.98
We need 42 of them,
Therefore, P(that none are defective) = (0.98)^42 = 0.4281
The probability that a specific battery will be the only defective battery is (0.02)*(0.98)^41
Since we have 42 of them, ((0.02)*(0.98)^41)*42 = 0.367
Note that
[tex]42C2=\frac{42!}{(42-2)!2!}=861[/tex]=> ((0.02)^2*(0.98)^40)*861 = 0.1535
Therefore, 0.4281 + 0.367 + 0.1535 = 0.9486
The probability shows that about 94.86% of all shipments will be accepted

Slope for (16, -10) and (16, 15) is undefined, slope for (-19, -6) and (15, 16) is 11/17, slope for (19, -2) and (-11, 10) is -2/5, and slope for (12, -18) and (-15, 18) is -4/3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
For (16, -10) and (16, 15)
m=15-(-10)/16-16=15+10/0=25/0=undefined
For (-19, -6) and (15, 16)
m=16-(-6)/15-(-19)
=22/34=11/17
For (19, -2) and (-11, 10)
m=10-(-2)/-11-19
=10+2/-30
=-12/30=-2/5
For (12, -18) and (-15, 18)
m=18-(-18)/-15-12
=36/-27
=-12/9
=-4/3
Hence slope for (16, -10) and (16, 15) is undefined, slope for (-19, -6) and (15, 16) is 11/17, slope for (19, -2) and (-11, 10) is -2/5, and slope for (12, -18) and (-15, 18) is -4/3.

Write the equation to solve and then find the measure of each acute angle(3x + 8° (2x + 12)°
Answers
We have here a right triangle, and that is why we have two acute angles (that is, the measure of each of them is less than 90 degrees).
We also know that the sum of the inner angles of a triangle is 180 degrees.
Having this information at hand, we can proceed as follows:
[tex](3x+8)+(2x+12)+90=180[/tex]This is the equation. Now, we need to solve this equation to find x, and then we need to use the algebraical equations to find each of the acute angles.
Solving the equation
1. Sum the like terms (like terms have the same variable or they are constants.)
[tex]3x+2x+8+12+90=180[/tex]Then, we have:
[tex]5x+110=180\Rightarrow5x=180-110\Rightarrow5x=70[/tex]2. We need to divide each side of the equation by 5 to isolate x:
[tex]\frac{5x}{5}=\frac{70}{5}\Rightarrow x=14[/tex]Now, we have x = 14. Therefore, the values for each of the acute angles are (we need to substitute the value of x in each equation):
a. 3x + 8 ---> 3 * (14) +8 = 42 + 8 =50. Hence, one acute angle measures 50 degrees.
b. 2x + 12 ---> 2 * (14) + 12 = 28 + 12 = 40 degrees. Therefore, the other acute angle measures 40 degrees.
In summary, the equation to solve is:
[tex](3x+8)+(2x+12)+90=180[/tex]And the values for each of the acute angles are 50 and 40 degrees.

A small town has two local high schools. High School A currently has 900 students and is projected to grow by 50 students each year. High School B currently has 500 students and is projected to grow by 100 students each year.

Graph each function and determine which high school is projected to have more students in 4 years.
Answers
ANSWER
Red line: function A(t)
Blue line: function B(t)
High school A is projected to have more students in 4 years.
EXPLANATION
We have,
• A: number of students in school A after t years
,• B: number of students in school B after t years
School A is projected to have 50 more students each year, while school B is projected to have 100 more students each year. Thus, both functions are linear.
High school A starts with 900 students and each year it will have 50 more,
[tex]A(t)=900+50t[/tex]On the other hand, high school B starts with 500 students and each year will have 100 more,
[tex]B(t)=500+100t[/tex]In 4 years each school will have,
[tex]A(4)=900+50\cdot4=900+200=1100[/tex][tex]B(4)=500+100\cdot4=500+400=900[/tex]The graphs of each function are lines. The graph of A is a line passing through points (0, 900) - which is the y-intercept, and (4, 1100).
The graph of B is a line passing through points (0, 500) and (4, 900).
From these calculations and from the graph, we can see that function A has a higher value than function B at t = 4. Hence High School A is projected to have more students in 4 years.

The events A and B are dependent events. This is because unlike the red area, event A means green given that blue has already occured. Event A includes blue and green and then event B includes green and yellow. Therefore event B cannot take place unless event A (which includes green area) has already taken place. Same goes for event A, it cannot take place unless event B has occured because the green area occurs in event B. Both events are dependent events. The result of one will influence the result of the other on.

[tex]\begin{gathered} R(2.04)=-240(2.04)^2+980(2.04)\Rightarrow R(2.04)=1000.416... \\ \\ \Rightarrow R(2.04)\approx1000.42 \end{gathered}[/tex]So, the maximum revenue is approximately $1000.42.
Consider the function f(x) = 22 - 102 – 24. Given that one of the solutions of thefunction is r = -2 , what is the other solution of the function?
Answers
The initial function is:
[tex]f(x)=x^2-10x-24[/tex]And we know that one solution is r=-2
Find the volume of a road construction marker, a cone with height 2 ft and base radius 1/5 ft. Use 3.14 as an approximation for π.The volume of the cone is __. (ft^2, ft^3, ft)(Simplify your answer. Type an integer or decimal rounded go the nearest hundredth as needed.)
Answers
Remember that
The volume of a cone is equal to
[tex]V=\frac{1}{3}\cdot\pi\cdot r^2\cdot h[/tex]we have
r=1/5 ft
pi=3.14
h=2 ft
substitute given values
[tex]\begin{gathered} V=\frac{1}{3}\cdot3.14\cdot(\frac{1}{5})^2\cdot2 \\ V=0.08\text{ ft3} \end{gathered}[/tex]the answer is 0.08 ft^3Cindy read a total of 8 books over 2 months. If Cindy has read 20 books so far, how many

Use the protractor to find the measure of ABC. Then classify the angle.
Answers
We are asked to find the measure of angle ABC and classify the angle.
As you can see from the figure, vertex A is at 30° and vertex C is at 155°
So, the angle ABC is
[tex]\angle ABC=155\degree-30\degree=125\degree[/tex]So, the angle ABC is 125°
Now recall that an obtuse angle is greater than 90° and less than 180°
Since 125° is between 90° and 180°, therefore, the angle ABC is an obtuse angle.
