Step-by-step explanation:
Championship T-shirts sell for $22 each.
What point(s) MUST be on the graph for the quantities to be proportional to each other?
The points that must be on the graph for the quantities to be proportional to each other are (2, 44), (3, 66) and (4, 88)
How to determine the points that must be on the graph?From the question, we have the following parameters that can be used in our computation:
Championship T-shirts sell for $22 each.
The above parameter means that
The unit rate of a T-shirt = $22
This can be represented as
Unit rate = 22
The interpretation of the above rate is that:
The number of n T-shirts is the unit rate multiplied by n
So, we have the following equation
Cost of n shirts = Unit Rate * n
When the number of shirts is 2, we have
Cost of 2 shirts = 22 * 2
Cost of 2 shirts = 44
When the number of shirts is 3, we have
Cost of 3 shirts = 22 * 3
Cost of 3 shirts = 66
When the number of shirts is 4, we have
Cost of 8 shirts = 22 * 4
Cost of 4 shirts = 88
So, the points are (2, 44), (3, 66) and (4, 88)

A credit union client deposits $2,500 in an account earning 7% interest, compounded annually. What will the balance of the account be at the end of 21 years?
Enter the answer in dollars and cents, and round to the nearest cent, if needed. Do not include the dollar sign. For example, if the answer is $0.61, only the number 0.61 should be entered.
Balance ≈ $______________ after 21 years.
The balance of the account at the end of 21 years, given the deposit amount and the interest rate is $10, 351. 41
How to find the balance on the account?The balance on the account at the end of 21 years is the future value of the amount in the account today. This means that this balance can be found by the formula:
= Amount deposited x ( 1 + rate) ^ number of years
The balance on the Credit union client's account after 21 years is therefore:

198.02% of £83.02
83.02
Give your answer rounded to 2 DP
The value of 198.02 percent of £83.02 is £164.40
How to calculate the value?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
The value will be illustrated thus:
198.02% × £83.02
= 1.9802 × £83.02
= £164.3962
= £164.40

The probability that Jordan will win in three or fewer matches if they play 5 matches using binomial probability distribution is; 0.95636
How to solve Binomial probability distribution problems?The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability.
The general formula for binomial probability distribution is;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
where;
Px = the probability of exactly x events occurring
x = the number of expected successful outcomes
n = the number of trials you perform
nCx = the number of different combinations for x items you test in n trials
We are given probability that Jordan wins the match as 1/3. Thus;
p = 1/3 = 0.333
Thus, probability that Jordan will win in three or fewer matches if they play 5 matches is;
P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)
From online binomial probability calculator, we have;
P(X ≤ 3) = 0.95636

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=7000(1.97)
The given exponential function is increasing so it will be growth and the percentage increase is 97%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given function,
y = 7000(1.97)^x
As x increase the 1.97^x will be increased thus, y will be increased so it will be growth.
Suppose x = 0
y = 7000
Suppose x = 1
y = 1.97 x 7000
% increase = (1.97 x 7000 - 7000)/7000
% increase = 97 %
Hence "The given exponential function is increasing so it will be growth and the percentage increase is 97%".

The first guitar lesson will cost (E $80
How to know the cost of the first lesson'The cost of the first lesson is solved by comparing the costs
Since the cost of the first lesson is twice the cost of each additional lessons, double counting the first lesson makes the total number of lesson to be 9
if 9 lessons costs $360 then 1 lesson will cost
9 = 360
1 = ?
cross multiplying
8 * ? = 360 * 1

The nth term of a series is represented by an=4n/5^n+1 ⋅n.
Otto correctly applies the ratio test to determine whether the series converges or diverges.
Which statement reflects Otto's conclusion?
The nth term of the series is 0.8 < 1 so, the series converges. Therefore, option C is the correct answer.
Given that, the nth term of a series represented by [tex]a_n=\frac{4^n}{5^{n+1}.n}[/tex].
What is the series converges or diverges?A convergent series is a series whose partial sums tend to a specific number, also called a limit. A divergent series is a series whose partial sums, by contrast, don't approach a limit. Divergent series typically go to ∞, go to −∞, or don't approach one specific number.
Next term in the series is [tex]a_{n+1}=\frac{4^{n+1}}{5^{n+2}.(n+1)}[/tex]
Now, the ratio is [tex]|\frac{a_{n+1}}{a_n}| =|\frac{\frac{4^{n+1}}{5^{n+2}.(n+1)}}{\frac{4^n}{5^{n+1}.n}}}|[/tex]
⇒ [tex]\lim_{n \to \infty}| \frac{a_{n+1}}{a_n} |= \lim_{n \to \infty} | \frac{\frac{4^{n+1}}{5^{n+2}.(n+1)}}{\frac{4^n}{5^{n+1}.n}}}|[/tex]

Find the unit price for each brand. Then state which brand is the better buy based on the unit price.
Round your answers to the nearest cent.
The unit price for brand A is $0.0517 and the unit price for brand B is $0.0828. Based on the unit price Brand A is better to buy.
Given that, Brand A has a box of 42 forks for $2.17. Brand B has a box of 48 forks for $3.97.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here,
The cost of each fork of brand A
= 2.17/42
= $0.0517
The cost of each fork of brand B
= 3.97/48
= $0.0828

Complete parts a and b . Express the originall claim in symbolic form. Let the parameter represent a value with respect to homes that have only a landscape telephone and no wireless phone
a) The original claim expressed in symbolic form is; p > 0.032
b) The hypotheses are defined as;
Null hypothesis; H₀: p ≤ 0.032

How to define the hypotheses?A hypothesis is defined as an educated guess while using reasonable thinking, about the answer to a scientific question.
a) We are told that the claim is that more than 3.2% (0.032) of homes have only a landline telephone and no wireless phone. Thus, the original claim in symbolic form is; p > 0.032
b) From the sample survey that we see, it is clear that among 15800 homes, 5.81% had landline phones without wireless phones. This would be the sample proportion.
