Knowing that the final course grade is determined in the manner described above, Kyra can figure out what grade she needs to earn on the final exam to earn at least a 90% for her final course grade. These are her other grades she has earned so far: Q1 = 92%, Q2 = 85%, Q3 = 88%, Q4 = 84%, and mid-term exam = 89%. What is the least whole percent she must earn on the final exam?
Answers
Answer: Kyra must earn at least 100% on the final exam.
Step-by-step explanation: Kyra's scores have been accumulating from Q1 to Q4 and then the mid term exam. Her scores are outlined as follows;
Q1 = 92, Q2 = 85, Q3 = 88, Q4 = 84, mid-term = 89.
Observe carefully that the data set (number of observed data) is 5.
What she needs now is a final average score of at least 90% after her final exam. She can use this to determine what she needs to score in her final exam. In other words, now that she has a average score, all she needs is a total of all her scores up till her final exam. Note that after writing her final exam, the data set would be six and no longer five.
Before writing her final exam, Kyra's average score was calculated as;
Average = (92 + 85 + 88 + 84 + 89)/5
However after she must have written her final exam, her average would be calculated as;
Average = (92 + 85 + 88 + 84 + 89 + x)/6
Where average is given as 90 and x is the final exam score, you now have
90 = (438 +x)/6
90*6 = 438 + x
540 = 438 + x
Subtract 438 from both sides of the equation
102 = x
Therefore from the results shown, Kyra must score up to 102% in her final exam. However, knowing that she cannot obtain a score higher than 100%, we can conclude that she must score nothing less than 100% (a hundred percent) in her final exam.

Megan wants to know if the number of words on a page in her English book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
She claims that because the mean number of words on each page in the English book is greater than the mean number of words on each page in the math book, the English book has more words per page. Based on the data, is this a valid inference? (1 point)
Group of answer choices
A) Yes, because the mean is larger in the English book.
B) No, because the mean is larger in the English book.

If a value of 98° is added to the data, how does the mean change?
A. The mean increases by 8.2°.
B. The mean decreases by 8.2°.
C. The mean increases by 1.4°.
D. The mean decreases by 1.4°.
Answers
Answer:
C. The mean increases by 1.4°.
Step-by-step explanation:
if you count the number of numbers in the set {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57} it is 12 numbers.
The formula for mean is, \(mean=\frac{sum- of- the- terms}{number-of-terms}\)
so if you add all the numbers here →, {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57} you get a sum of 965.
Now 965 ➗12= 80.4166666667
If 98 is added we add 98 to 965 and get 1063.
That also means an additional number is being added so 12+1 = 13.
Now, 1063➗13= 81.7692307692
Ok now we approximate, 80.4166666667 is about 80.4 and 81.7692307692 is about 81.8.
Now we subtract 81.8-80.4 and get 1.4.
It was an increase of 1.4 in the mean so the answer is C.

Step-by-step explanation:
You can use simple logic in order to solve this equation.
An equation that has infinitely many solutions will have the same exact numbers on both sides
Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true
The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

If x and y vary directly and y is 6 when x is 8, find y when x is 12.
Answers
Answer:
If x and y vary directly and y is 6 when x is 8, y is 9 when x is 12.
Step-by-step explanation:
In the given problem, it is known that when x is 8, y is 6, so the constant of proportionality in this case is k = y/x = 6/8 = 3/4. This means that the relationship between x and y can be written as y = (3/4)x.
To find the value of y when x is 12, we can plug this value into the equation to get y = (3/4) * 12 = 9. Therefore, if x and y vary directly and y is 6 when x is 8, y is 9 when x is 12.
Answer:
y is 9 when x is 12
Step-by-step explanation:
the ratio of x to y is 4:3
Write and solve a real-world problem involving a percent of increase with decimals.
Please help and thank you in advance! =)
Answers
Step-by-step explanation:
Here's a real-world problem involving a percent increase with decimals:
Suppose you have a savings account with a balance of $500. The bank offers an interest rate of 2.5% per year. How much will your balance increase after one year, including the interest earned?
To solve this problem, we can use the formula for percent increase:
Percent increase = (new value - old value) / old value x 100%
Let x be the amount of interest earned after one year. Then, the new value of the savings account after one year is:
New value = old value + interest earned
New value = $500 + x
The percent increase is given as 2.5%, which can be written as a decimal as 0.025. Using the formula above, we can write:
0.025 = (New value - $500) / $500 x 100%
Simplifying this equation, we get:
New value - $500 = $500 x 0.025
New value - $500 = $12.50
New value = $512.50
Therefore, the balance of the savings account will increase by $12.50 after one year, which represents a 2.5% increase from the original balance of $500. The new balance will be $512.50.

Answers
Answer:
question 2 is A; 15%
Step-by-step explanation:
the change in price is $18; 18 is 15% of 120
The old fare of a Airlines ticket from New Orleans to Boston is 18333 cents. and the change in price is 15% of 120
Find out the old fare to the nearest cent?Let the old price of the ticket = $100
Price is increased by 30%
We can write it as;
New price = $100+ $ 30
New price = $130
We know that 30% = $550
then 100% = $550 × 100 / 30
So the old fare = $550,00 / 30
=$ 1833.3
1 dollars = 100 cents
$ 1833.3 = 18333 cents
Hence , the old fare of a Airlines ticket from New Orleans to Boston is 18333 cents.
Then the change in price is 15% of 120

Three kids,Nicole,oluwatomi and muna shared 500 in the ratio of 3:2:x respectively.If nicole share is 150,find the value of x
Answers
Answer: X= 5
Step-by-step explanation:
The ratio 3:2:x may also be written as Nicole:oluwatomi:muna which means that Nicole is 3y olwatomi is 2y and muna is xy. We also know that all their values together add up to 500
Using the information above we can set up an equation:
3y+2y+xy=500. If’s you simplify this equation you get 5y+xy=500
Going onto the next step we know that Nicole’s share is 150. We can set up an equation using this information:
150=3y. After simplifying we know that y=50
So if we go back to our first equation: 5y+xy=500 we can substitute y with 50.
5*50+x*50=500 after we solve this equation we can get the result X=5
