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

Answer:

To complete the table for the function:

y = 3*x - 1

We just need to replace the values of x, and that will give use the correspondent value of y.

when x = -2, we have:

y = 3*(-2) - 1 = -6 - 1 = -7

when x = 0, we have:

y = 3*(0) - 1 = -1

when x = 1 we have:

y = 3*(1) -1 = 3 - 1 = 2

when x = 3 we have:

y = 3*(3) - 1 = 9 - 1 = 8

Then the table is:

x   -2    -1    0    1    2    3

y   -7    -4   -1    2   5    8

Now, to graph the line, we just need to find those points in the grid, and then draw a line that passes through all of them, the line will be something like the one in the image below.

Now, to estimate the value of y when x = 2.5

We first need to locate x = 2.5 in the horizontal grid, now let's do a vertical line upwards. When this vertical line touches the line of the graph, we see which value of y (the vertical axis) corresponds with that.

In this case, when x = 2.5, y = 6.5

Answer:

$45000 should be invested in stocks

Step-by-step explanation:

Given

Represent Bonds with B and stocks with S

\(S + B = 72000\)

\(5B = 3S\)

Required

Determine the values of S

Solve for B in \(5B = 3S\)

\(B = \frac{3}{5}S\)

Substitute \(\frac{3}{5}S\) for B in \(S + B = 72000\)

\(S + \frac{3}{5}S = 72000\)

\(\frac{5+3}{5}S = 72000\)

\(\frac{8}{5}S = 72000\)

Solve for S

\(S = 72000 * \frac{5}{8}\)

\(S = \frac{72000 * 5}{8}\)

\(S = \frac{360000}{8}\)

\(S = 45000\)

Hence: $45000 should be invested in stocks

The nearest Whole percent, the percent increase of women students is approximately 21%.

The percent increase of women students, we need to compare the number of women students in 2005 and 2006.

In 2005, the number of women students was 123.

In 2006, the number of women students was 149.

To find the increase, we subtract the initial value (2005) from the final value (2006):

Increase = Final Value - Initial Value

Increase = 149 - 123

Increase = 26

Next, we need to calculate the percent increase. The percent increase is given by the formula:

Percent Increase = (Increase / Initial Value) * 100

Plugging in the values:

Percent Increase = (26 / 123) * 100

Calculating the percent increase:

Percent Increase ≈ 21.14%

Rounding to the nearest whole percent, the percent increase of women students is approximately 21%.

Answer:

Step-by-step explanation:

310 is the answer.

Answer:

84

Step-by-step explanation:

Let's call the father's present age "F" and the son's present age "S".

Five years ago, the father's age was F - 5 and the son's age was S - 5.

According to the first statement, F - 5 = 6(S - 5), so F = 6S - 35.

Two years in the future, the father's age will be F + 2 and the son's age will be S + 2.

According to the second statement, F + 2 = 3(S + 2) + 1, so F = 3S + 7.

We can now substitute the first equation into the second:

3S + 7 = 6S - 28,

3S - 6S = -35 - 7 = -42,

-3S = -42,

S = 14.

Finally, the father's present age is F = 6S - 35 = 84.

Answer:

The dad is 35 and the son is 10

Step-by-step explanation:

Let f =  the father's age

let s - the son's age

In the equations f-5 and s-5 represents the father and son's ages 5 years ago.   f + 2 and s +2 represent the father and son's ages two years in the future.

To calculate the amount of money in the account after 1 year, we can use the following formula:

A = P(1 + r/n)^nt

Where:

Plugging in the given values, we get:

A = 500(1 + 0.05/4)^4*1

A = 500(1.0125)^4

A = $515.63

Therefore, after 1 year, the account will have $515.63.

According to the unitary method,

A) The time taken for Peter to finish the job alone is 4 hours, 48 minutes.

B) The time taken for Emily and Peter to finish the job together is 2 hours, 36 minutes.

Unitary method:

In math, unitary method refers the process of finding the value of a single unit, and based on this value.

Given,

Emily, Ashley and Peter can clean a warehouse in 2 hours. If Emily does the job alone, she can finish it in 6 hours. If Ashley does the job alone she can finish it in 8 hours.

Here we need to find the following:

A) The time take for Peter to finish the job alone

B) The time taken for Emily and Peter to finish the job together

Let us consider x be the time taken for Peter to finish the job alone.

So, based on the given question we can write it as,

=> 1/6 + 1/8 + 1/x = 1/2

=> (8 + 6)/48 + 1/x = 1/2

=> 14/48 + 1/x = 1/2

=> 7/24 + 1/x = 1/2

=> 1/x = 1/2 - 7/24

=> 1/x = 12 -7/24

=> 1/x = 5/24

=> x = 24/5

=> x = 4.8

So, the time taken for Peter to finish the job alone is 4 hours, 48 minutes.

Then the time taken for Emily and Peter to finish the job together is calculated as,

=> 5/24 + 1/6

=> 5 + 4/ 24

=> 9/24

=> 3/8

Therefore, the time taken for Emily and Peter to finish the job together 2 hours, 36 minutes.

The answer would be A

Step-by-step explanation:

If you were to divide 36 by 5 you would be finding how many calories are in 1/5 of a bar.

You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.

When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.

A cuboid has six faces, but each face has a pair that is identical in size and shape.

Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.

To find the surface area of a cuboid, you can add up the areas of all its faces.

However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:

(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.

By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.

Essentially, you are considering one face from each pair and then summing their areas.

Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.

When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.

Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.

Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.
