Answer:
104
Step-by-step explanation:
Let's say that the numbers are x and y. So, we know that....
x+y=186
y-x=22
Now we can use the substitution method to find the numbers. y-x=22 turns into y=22+x. And now we can substitute to the second equation into the first equation.
x+22+x=186
2x=164
x=82
y=22+82
y=104
Our numbers are 82 and 104 and the larger integer is 104, so that's the answer.
Answer:
I believe the answer is 104.
Step-by-step explanation:
Because 186 - 104 = 82 and 104 - 22 = 82.
Ellie read an article claiming that 10% of people in her county were senior citizens, and she thought that it may be higher for residents in her city. She took a random sample of 225 people from her city and found that 36 of them were senior citizens. She wants to test H0:p=0.10 versus Ha:p > 0.10, where p is the proportion of people in her city that are senior citizens. Assuming that the conditions for inference have been met.
Required:
Calculate the test statistic for Ellie's significance test.
Answer:
The value is \(z = 3\)
Step-by-step explanation:
From the question we are told that
The population proportion of senior citizens is \(p = 0.10\)
The sample size is \(n = 225\)
The number of senior citizens is k = 36
The null hypothesis is \(H_o : p = 0.10\)
The alternative hypothesis is \(H_a : p > 0.10\)
Generally the sample proportion is mathematically represented as
\(\^{p} = \frac{k}{n}\)
=> \(\^{p} = \frac{ 36 }{225}\)
=> \(\^{p} =0.16\)
Generally the test statistics is mathematically represented as
\(z = \frac{\^{p} - p }{\sqrt{\frac{p(1 -p )}{n} } }\)
=> \(z = \frac{0.16 - 0.10 }{\sqrt{\frac{p(1 -0.10)}{225} } }\)
=> \(z = 3\)

If LN = 6x - 5, LM = x + 7, and MN = 3x + 20, find MN.
A.68
B.16
C.23
D.18
Answer : The correct option is (A) 68.
Step-by-step explanation :
As we are given that:
LN = 6x - 5
LM = x + 7
MN = 3x + 20
Now we have to determine the value of MN.
According to the question:
LN = LM + MN
Now putting all the given values in this expression, we get:
6x - 5 = (x + 7) + (3x + 20)
6x - 5 = 4x + 27
6x - 4x = 27 + 5
2x = 32
x = 16
The value of MN = 3x + 20 = 3(16) + 20 = 48 + 20 = 68
Therefore, the value of MN is 68.
Your friend has a bag of yellow and purple candy. He wants to use them to play a game with you.
Purple is worth 2 points and yellow is worth three points. Pick 9 candies from the bag
Create a system of equations where the combination of the candies gives you a total of 22 points. Make sure you label and define your variables.
The system of equations where the combination of the candies gives you a total of 22 points are:
x + y = 9
2x + 3y = 22
How can we create system of equations?To create the equations, we shall first define the variables:
x = the number of purple candies
y = the number of yellow candies
Next, we shall use the given information that purple candies are worth 2 points and yellow candies are worth 3 points.
Then, we would make sure that the total number of candies selected is 9.
The first equation represents the total number of candies selected:
x + y = 9
The second equation represents the total number of points obtained:
2x + 3y = 22
Therefore, the system of equations is:
x + y = 9
2x + 3y = 22
This is a system of linear equations.

Tell whether each triangle with the given side lengths is a right triangle. Explain your answer by showing your solution when the side lengths are applied to the Pythagorean Theorem. 11cm, 60cm 61cm Answer: Solution:
Answer: yes
Solution: 3721 = 3721
Explanation:To determine if the lengths of a triangle is a right angle, it must satisfy the pythagoras' theorem:
Hypotenuse² = opposite² + adjacent²
hypotenuse = longest side = 61 cm
In this case, any of the other two sides can be represented by adjacent and opposite
opposite = 60cm
adjacent = 11 cm
Inserting into the formula:
61² = 60² + 11²
3721 = 3600 + 121
3721 = 3721
Since the left hand side of the equation is equal to the right hand side of the equation, the side lengths given is a right triangle.
Answer: yes
Solution: 3721 = 3721

Find the measure of arc BC.
Answer: A 129
Step-by-step explanation:
Because the 2 chords are the same (lines in the circle), the 2 arcs are the same create an equation that makes them equal
3x+24 = 4x -11 >bring x to one side by subtracting both sides by 3x
24 = x -11 > add both sides by 11
35 = x
Now that we have solved for x you need to plug that back into the equation for BC
BC= 4x-11
BC = 4(35) - 11
BC = 140 - 11
BC = 129 >A

Your original grades on your exams were: 75, 85, 90, 90, 100, 75, 80, 100, 90. You retake the exams and now your scores are: 85, 85, 100, 90, 100, 85, 80, 100, 90. By how many percentage points did you improve your average score? Hint: Find the mean of both sets of data. Then find the difference between the two. Round to the nearest %.
Based on your original grades in your exams and the scores after you retake your exams, the percentage points you improved your average score by is 3.83%
How to find the percentage improvement?To find the percentage that you improved by, the first thing to do is to find your average score in the first exam:
= (75 + 85 + 90 + 90 + 100 + 75 + 80 + 100 + 90) / 9
= 785 / 9
= 87.22
The average score after the exam was retaken was:
= (85 + 85 + 100 + 90 + 100 + 85 + 80 + 100 + 90) / 9
= 815 / 9
= 90.56
The percentage increase is:
= (90.56 - 87.22) / 87.22 x 100%
= 0.0382939692731024994267369869296 x 100%

Hope this helped :)
Answer:
A. 6/4
Step-by-step explanation:
B, C, and D are all equal to the ratio 2:3.
On the other hand, A is not equivalent to the other 3.
If we simplify A, it gets us the ratio 3:2, instead of 2:3
So, A is the ratio that is not equivalent to the others.
Los dueños de un restaurante exitoso quieren un préstamo de $50,000 para renovar la cocina y ampliar el comedor. Esperan que las mesas extra agreguen entre $2,000 y $5,000 a los ingresos mensuales del restaurante. El banco está dispuesto a permitir que la empresa tenga un préstamo a plazo intermedio de $50 000 durante cinco años a una tasa de interés del 6,5 por ciento. Calcule el pago mensual y explique si tomar este préstamo es una decisión comercial inteligente.
The monthly Payment for the loan is approximately $271.24.
To calculate the monthly payment for the loan, we can use the formula for calculating the monthly payment on an intermediate-term loan. The formula is:
Monthly Payment = (Loan Amount * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Months))
Given:
Loan Amount = $50,000
Interest Rate = 6.5% per year
Number of Years = 5
First, we need to convert the annual interest rate to a monthly interest rate. Since there are 12 months in a year, the monthly interest rate is:
Monthly Interest Rate = (6.5% / 100) / 12 = 0.00541667
Plugging in the values into the formula, we get:
Monthly Payment = ($50,000 * 0.00541667) / (1 - (1 + 0.00541667)^(-5 * 12))
= $271.24
Therefore, the monthly payment for the loan is approximately $271.24.
The owners of the restaurant want to use the loan to renovate the kitchen and expand the dining room, which they expect will generate additional monthly revenue between $2,000 and $5,000.
If we assume a conservative estimate of $2,000 per month in additional revenue, the loan payment of $271.24 represents approximately 13.56% of the additional revenue. This means that the owners would still have a significant portion of the additional revenue available for other expenses or profit.
On the other hand, if we consider the higher estimate of $5,000 per month in additional revenue, the loan payment would represent only about 5.42% of the additional revenue, leaving a substantial amount of money for other purposes.
Considering these calculations, it appears that taking this loan is a smart business decision. The monthly payment is manageable and leaves a significant portion of the additional revenue for the restaurant's operation and potential profit. However, it is essential for the owners to ensure that the projected additional revenue is realistic and sustainable to cover the loan payment and other business expenses.

Answer in fraction form: 297/20
Step-by-step explanation:
If f (x) = 2x2 – 5for - ♾ < x < 0,what is f-?(-2)?
To find the inverse, we:
• change f(x) to y
,• interchange x and y
,• solve for y
Thus,
\(\begin{gathered} f(x)=2x^2-5 \\ y=2x^2-5 \\ x=2y^2-5 \\ 2y^2=x+5 \\ y^2=\frac{x+5}{2} \\ y=\pm\sqrt[]{\frac{x+5}{2}} \\ f^{-1}(x)=-\sqrt[]{\frac{x+5}{2}} \end{gathered}\)We take the "negative" part of the function since it is defined for - ♾ < x < 0.
We found inverse of f.
Now, to find f^(-1) (-2), we put -2 into the inverse and evaluate.
\(\begin{gathered} f^{-1}(x)=-\sqrt[]{\frac{x+5}{2}} \\ f^{-1}(-2)=-\sqrt[]{\frac{-2+5}{2}} \\ =-\sqrt[]{\frac{3}{2}} \end{gathered}\)When simplifying an algebraic expression, we are allowed to combine "like terms.” How do we know when two or more terms are “like”?
