After four years of higher education, Danielle just graduated with a Bachelor's degree in Legal Studies from Georgetown where the annual cost of tuition was $26,000. She paid for college by earning $12,000 annually through the work study program and receiving an annual scholarship. She covered the remainder of the costs by taking out $0 in student loans. If she didn't fund her education with savings or grant money, what was the amount of Danielle's annual academic scholarship?
The amount of Danielle's annual scholarship is $14,000.
What is the value of the annual scholarship?
Subtraction is an arithmetic operation that is used to determine the difference between two or more numbers. The sign used to represent subtraction is -.
annual scholarship = annual tuition - annual earning
$26,000 - $12,000 = $14,000

A small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream. Find the rate of the current. (Hint: 8+x= rate going downstream and 8−x= rate going upstream.)(Round your answer to the nearest tenth.)
The rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
Let's suppose the rate of the current = r
The time it takes to go downstream + 4 hours = time to go upstream
As we know the:
[tex]\rm Time = \dfrac{Distance}{ Rate }[/tex]
Now,
[tex]\rm \dfrac{44}{ (8 + r)} + 3 = \dfrac{44}{ (8 - r)}[/tex]
After solving:
[tex]\rm \dfrac{44}{ (8 - r)}-\dfrac{44}{ (8 + r)} =3[/tex]
After cross multiplication
44(8+r) - 44(8-r) = 3(8+r)(8-r)
88r = 3(64 - r²)
3r² + 88r - 192 = 0
After solving the above quadratic equation, we get:
r = 2.03 or
r=−31.37 (reject as it is negative)
So, the r =2.03 mph
Thus, the rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.

An art museum has 20 large cylindrical columns in its lobby. Each column has a height of 22 feet from
the floor to the ceiling and a diameter of 2.5 feet. If a gallon of paint covers 350 square feet, how
many gallons of paint must be purchased to paint the lateral surface area of all of the columns?
A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The amount of paint needed to paint 20 pillars is 9.874 gallons.
What is a cylinder?A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.
The curved surface area of a single-cylinder with a diameter of 2.5 feet and a height of 22 feet will be,
Curved surface area = πDh = π × 2.5 × 22 = 172.7875 ft²
The total area of 20 pillar = 20 × 172.7875 ft² = 3,455.75191 ft²
Since a gallon of paint can cover only 350 ft², therefore, the amount of paint that will be needed to paint 3,455.75191 ft² can be written as,
[tex]\text{Amount of paint needed} = \dfrac{3,455.75191\rm\ ft^2}{350\rm\ ft^2} = 9.874\rm\ gallons[/tex]
Hence, the amount of paint needed to paint 20 pillars is 9.874 gallons.

The maximum number of tourists in the third week will be maximum in the numberville city.The solution of f(x)=h(x) will be x(5,2).
What are equations?The equation is actually a relationship between the numbers and the variables.
To calculate the number of the tourists in the third week we will put the value 3 in every function:
[tex]f(x)=x^2+5x+10=(3)^2+(3\times 3)+10=29\\\\\\g(x)=3^x=3^3=27\\\\\\h(x)=10x=10\times 3=30[/tex]
So we can see that the function third h(x) numberville city is having a maximum number of tourists.
The solution of f(x)=h(x) will be calculated as:
[tex]x^2-3x+10=10x\\\\\\x^2-7x+10=0\\\\\\x^2-5x-2x+10=0\\\\\\x(x-5)-2(x-5)=0\\\\\\x=5,2[/tex]
Hence the solution of f(x)=h(x) will be x(5,2).

The owner of a local movie theater keeps track of the number of tickets sold in each purchase. The owner determines the probabilities based on these records. Let X represent the number of tickets bought in one purchase. The distribution for X is given in the table. A 2-column table with 5 rows. Column 1 is labeled number of tickets with entries 1, 2, 3, 4, 5. Column 2 is labeled Probability with entries 0.17, 0.55, 0.20, 0.06, 0.02. What is the probability that a randomly selected purchase has less than two tickets? 0.17 0.55 0.72 0.83
Answer:
0.17
Step-by-step explanation:
The probability for purchasing 2 tickets at a time can be given as 0.17. The correct option is (A).
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
Suppose X be the event to represent the number of tickets in purchase.
Then, as per the question distribution table can be formed as follows,
The number of tickets (X) P(X) Probability
1 0.17
2 0.55
3 0.20
4 0.06
5 0.02
Thus, the probability of selecting less than two tickets can be obtained as,
P(X < 2) = P(X = 1)
⇒ 0.17
Hence, the probability for a purchase to have less than two tickets is given as 0.17.

Using the dot plot concept, it is found that the left plot on the bottom row shows an unfair data-generating process.
What does a dot plot show?The dot plot shows the number of times each measure appears in the data-set.
In this problem, each trial has 5 possible outcomes and there are 20 trials, hence each number should appear 20/5 = 4 times.
On the left plot of the bottom row, outcomes 1 and 5 appear 7 times, while outcomes 2, 3 and 4 appear 2 times, which are the furthest values from 5, hence it is an unfair data-generating process.

0.62
0.30
0.68
0.32
Using the discrete distribution, it is found that the probability that it offers an even number of honors classes is of 0.68.
What is the discrete probability distribution?The distribution for the number of honors classes the school offers is given by:
P(X = 0) = 0.38P(X = 1) = 0.12.P(X = 2) = 0.25.P(X = 3) = 0.2.P(X = 4) = 0.05.Hence the probability of an even number is given by:
P(even) = P(X = 0) + P(X = 2) + P(X = 4) = 0.38 + 0.25 + 0.05 = 0.68.
