Question
If n(A) = 14, n(B) = 51, and n(An B) = 12, then what is n(A U B)?
Answers
The value of n(AUB) i.e. union of A and B is 53.
What are Intersections and Unions in Probablity?
The union of two sets results in a new set that contains all of the items from both sets. The union is abbreviated as A∪B or "A or B." The intersection of two sets yields a new set containing all of the members from both sets. The junction is denoted by the letters A∩B or "A and B."
Solution:
Given that,
n(A) = 14
n(B) = 51
n(A∩B) = 12
We know that thee formula is n(AUB) = n(A) + n(B) - n(A∩B)
Putting the values,
n(AUB) = 14 + 51 - 12 = 53
So, the answer for the value of n(AUB) = 53

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 1600 miles. What warranty should the company use if they want 94% of the tires to outlast the warranty?
Answers
Answer:
The warranty the company should use is of 57,520 mile.
Step-by-step explanation:
Let X denote the tread life of a particular brand of tire.
It is provided that, \(X\sim N(60,000, 1600^{2})\).
Also provided that the company wants 94% of the tires to outlast the warranty.
Let x denote the warranty .
That is, P (X > x) = 0.94.
⇒ P (X < x) = 0.06
⇒ P (Z < z) = 0.06
The corresponding value of z is -1.55.
*Use a z-table.
Compute the value of x as follows:
\(z=\frac{X-\mu}{\sigma}\\\\-1.55=\frac{x-60000}{1600}\\\\x=60000-(1.55\times 1600)\\\\x=57520\)
Thus, the warranty the company should use is of 57,520 mile.

The ESS Ravens bought pizza for $900 to sell at the football game. They kept 10 pizzas to feed the players after the game and sold the rest for $1040. There were 8 slices in each pizza. Their profit was 50 cents a slice.
a) How many pizzas were in the original order?
Answers
Answer: 45
Step-by-step explanation:
The total profit in all was \(1040-900=\$ 140\).
The total profit per pizza was \((0.50)(8)=\$4\).
This means they sold \(\frac{140}{4}=35\) pizzas.
Adding this to the 10 pizzas held back, there were \(35+10=45\) pizzas in the original order.

7. Choose the graph below that best represents the equation: x-y = -2
Answers
Answer: B
Step-by-step explanation:
First, we will turn this equation into slope-intercept form as it is easier to view in terms of a graph.
Given:
x - y = 2
Add y and subtract 2 from both sides of the equation:
y = x - 2
We can see that this equation has a y-intercept of -2, so it must intercept the graph at (0, -2). The answer option that meets these requirements is B.
Answer: it is graph A
Step-by-step explanation:
It is pretty easy to tell when x-y= -2
Let's say x is 0 then we have left is -y=-2
So y= 2
And we have [0,2] so graph A is correct

he temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 925 and a standard deviation of 60 degrees. If bricks are fired at a temperature above 1150, they will crack and must be disposed of. If the bricks are placed randomly throughout the kiln, the proportion of bricks that crack during the firing process is closest to
Answers
Answer:
The proportion of bricks that crack during the firing process is 0.0001 = 0.01%.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean of 925 and a standard deviation of 60 degrees.
This means that \(\mu = 925, \sigma = 60\)
The proportion of bricks that crack during the firing process is closest to
This is 1 subtracted by the pvalue of Z when X = 1150. So
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{1150 - 925}{60}\)
\(Z = 3.75\)
\(Z = 3.75\) has a pvalue of 0.9999
1 - 0.9999 = 0.0001
The proportion of bricks that crack during the firing process is 0.0001 = 0.01%.

Determine the open intervals on which the function is increasing, decreasing, or constant. (Enter your answers using interval notation.)
t + 2, t<0
F(t) = 2, 0 ≤ t ≤ 2
-t + 4, t > 2
increasing: ____________
decreasing: ___________
constant: ______________
Answers
The Function is increasing (-∞, 0), decreasing (2, ∞), and constant [0, 2].
The intervals on which the function is increasing, decreasing, or constant, we need to analyze the behavior of the function in each interval.
1. Interval t < 0:
In this interval, the function is given by f(t) = t + 2. Since the coefficient of t is positive (1), the function is increasing. Therefore, the interval t < 0 is an interval of increasing values.
2. Interval 0 ≤ t ≤ 2:
In this interval, the function is constant and given by f(t) = 2. The value of the function remains constant at 2 for all values of t in this interval.
3. Interval t > 2:
In this interval, the function is given by f(t) = -t + 4. Since the coefficient of t is negative (-1), the function is decreasing. Therefore, the interval t > 2 is an interval of decreasing values.
To summarize:
Increasing interval: t < 0
Decreasing interval: t > 2
Constant interval: 0 ≤ t ≤ 2
Using interval notation, we can express the intervals as follows:
Increasing interval: (-∞, 0)
Decreasing interval: (2, ∞)
Constant interval: [0, 2]
In interval notation, (a, b) denotes an open interval, which means it includes all values between a and b, but excludes the endpoints. [c, d] denotes a closed interval, which includes both endpoints c and d.
Therefore, the function is increasing on the interval (-∞, 0), decreasing on the interval (2, ∞), and constant on the interval [0, 2].

Find the Surface Area of a cone that has a slant height of 14 in and a diameter of 6 in. Remember to use the symbol when you plug it into your calculator. Round the answers to the nearest tenth.
Surface Area = ___ in2
Answers
The surafce area of the cone with a slant height of 14 in and a diameter of 6 in is 160.2 in².
What is the surface area of the cone?A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The surface area of a cone can be expressed as;
SA = πrl + πr²
Where r is radius of the base, l is the slant height of the cone and π is constant pi.
Given that:
Slant height l = 14 in
Diameter d = 6 in
Radius r = diameter/2 = 6/2 = 3in
S.A = ?
Plug the given values into the above formula and solve for the surface area.
SA = πrl + πr²
SA = ( π × 3in × 14in ) + ( π × (3in)² )
SA = 160.2 in²
Therefore, the surface area is 160.2 in².
