One year Terry had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of 2.85 . Also, Karla had the lowest ERA of any female pitcher at the school with an ERA of 2.95 . For the males, the mean ERA was 4.893 and the standard deviation was 0.949 . For the females, the mean ERA was 4.348 and the standard deviation was 0.997 . Find their respective z-scores. Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)
Answers
Answer:
Their respective z-scores are:
Thomas : -2.15279
Karla : -1.40221
Which player had the better year relative to their peers, Terry or Karla ?
Terry had a better year because he had a lower Era and he was a better pitcher.
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
any male pitcher at his school,
For Thomas:
z = (x-μ)/σ
x = 2.85 μ = 4.893 σ = 0.949.
z = 2.85 - 4.893/0.949
z = -2.15279
For Karla
z = (x-μ)/σ
x = 2.95 μ = 4.348 σ = 0.997.
z = (2.95 - 4.348) /0
z = -1.40221
Their respective z-scores are:
Thomas : -2.15279
Karla : -1.40221
Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)
Terry had a better year because he had a lower Era and he was a better pitcher.
Enter the missing values in the area model to find 8(8k + 9)
Answers
The area of a rectangular model is 64k²+72.
Given that, the length of a rectangle = 8k+9 units and the width of a rectangle = 8 units.
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Now area of a model is
(8k+9)×8
= 8×8k+8×9
= 64k²+72
Therefore, the area of a rectangular model is 64k²+72.

Kiaya has to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now. Each week, she makes a $25 withdrawal. For how many weeks can she make this withdrawal and avoid a fee?
Answers
Answer:
11 weeks
Step-by-step explanation:
Kiaya has $376 but can only withdraw $276 before being charged by the bank.
First I subtracted the $100 she can't spend from $376.
-She has a total of $276 she can spend without being charged.
Next, I divided $276 by $25 (the amount she withdraws every week)
- The total is 11.04
This means she has 11 Weeks before she will have to pay the fee.

EF = 11
JK = 32
Step-by-step explanation:
Because the average of 10 and 12 is 11, therefore that would be the answer, since EF has a slite angle, finding the average of the largest side length and the opposite side would be the best way to find it.
Because the average of 28 and 36 is 32 your answer would be 32, this is from adding both lengths on LJ, which is 12 and 24, I added them to get 36, then found the average, the average was 36, meaning that this was your answer.

A store owner wants to develop a new snack mix by mixing banana chips and raisins. How many pounds of banana chips costing $7.70 per pound should be mixed with 18 pounds of raisins costing $4.30 per pound to create a mixture worth $5.73 per pound?
Answers
The weight of the snack mix is c + 13.
16.2c + 4.1(13) = 9.65(c + 13)
16.2c + 53.3 = 9.65c + 125.45
6.55c = 72.15
c = 11 lbs
Find the area, in square units, of triangle ABC plotted below.
Answers
Answer:
Area of ΔABC = 10 square units
Step-by-step explanation:
Distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is represented by,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Length of AB = [tex]\sqrt{(-4-2)^2+(-6+8)^2}[/tex]
= [tex]\sqrt{36+4}[/tex]
= [tex]2\sqrt{10}[/tex]
Length of CD = [tex]\sqrt{(-6+7)^2+(-2+5)^2}[/tex]
= [tex]\sqrt{1+9}[/tex]
= [tex]\sqrt{10}[/tex]
Area of a triangle ABC will be represented by the formula,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(AB)(CD)[/tex]

The function yields the average cost in dollars for a company to produce x copies of a comic book. Which statement best fits the situation modeled by the function? The company earns 20% of the issue price as profit from each copy sold. The company earns 20 cents as profit from each copy sold. The company spends 20% of the issue price on materials to produce each copy. The company spends 20 cents on materials to produce each copy.
Answers
Answer: 20cents
Step-by-step explanation;
Company spends 20 cents on materials to produce each copy
f(x) represents the average cost in dollars for a company
x represents the number of copies of comic produced by company.
Total cost in dollars for a company = 80,000 + 0.2x
Since, x is the number of copies of comic produced ,
0.2x indicates that it spends $0.2 on material to produce each copy.
Use conversion:
1 dollars = 100 cents
0.2 dollars = 20 cents.
Answer:
The correct option is D the company spends 20 cents on materials to make each copy

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The third one down.
32.1y+3.1+2.4y-8.2=34.5y-5.1
Combine like terms
34.5y + 3.1 - 8.2 = 34.5y - 5.1
34.5y - 5.1 = 34.5y - 5.1 y can be anything
===========================
Remove the brackets from D
11y + 17 = 5y - 10 + 6y
11y + 17 = 11y - 10
This gives 17 = - 10 which of course is nonsense.
D has no solution.
