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.)
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.

Write the equation of a line that includes the point (1, 5) and has a slope of 3 in slope-intercept form
Answer:
y=3x+2
Step-by-step explanation:
y=mx+b
We have our m, which is slope, but we need our y intercept, b.
Substitute your slope, x, and y into the formula and solve for b.
5=3(1)+b
5=3+b
-3 -3
2=b
Now we can plug into equation.
y=3x+2

Combine like terms

h(x)=2x+5 k(x)=x+3 find (h(k(x)))
Answer:
h(k(x)) = 2x + 11
Step-by-step explanation:
Step 1: Define
h(x) = 2x + 5
k(x) = x + 3
h(k(x))
Step 2: Substitute and Evaluate
k(x) = x + 3 = x
h(k(x)) = 2(x + 3) + 5
h(k(x)) = 2x + 6 + 5
h(k(x)) = 2x + 11

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)
Answer:
25811Step-by-step explanation:
We are given the rule [ f(n) = 3n - 1 ] and n represents the term.
First term:
f(n) = 3n - 1
f(1) = 3(1) - 1
f(1) = 3 - 1
f(-1) = 2
Second term:
f(n) = 3n - 1
f(2) = 3(2) - 1
f(2) = 6 - 1
f(2) = 5
Third term:
f(n) = 3n - 1
f(3) = 3(3) - 1
f(3) = 9 - 1
f(3) = 8
Fourth term:
f(n) = 3n - 1
f(4) = 3(4) - 1
f(4) = 12 - 1
f(4) = 11
As you can see, the common difference is 3.
Best of Luck!
Answer:
2,5,8,11
Step-by-step explanation:
If n=1, 3n-1 =3*1-1 =3-1 =2
If n=2, 3n-1 =3*2-1 =6-1 =5
If n=3, 3n-1 =3*3-1 =9-1 =8
If n=4, 3n-1 =3*4-1 =12-1 =11
Susan buys a new computer 1200 dollars.Sales tax is 11%. How much does Susan actually have to pay?
The amount that Susan actually have to pay should be considered as the $1,332.
Calculation of the amount:
Since the purchase price of the computer is $1,200
And, the sales tax rate is 11%
So here the total amount be like
= $1,200 + 11% of $1,200
= $1,200 + $132
= $1,332
hence, The amount that Susan actually have to pay should be considered as the $1,332.

the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average
Answer:
They need more than 2.5 inches.
Step-by-step explanation:
average = 5.3
June: 6.3
July: 7.1
August: x
The average of the amounts for June, July, and August is
(6.3 + 7.1 + x)/3
To exceed the average, the average must be greater than 5.3.
(6.3 + 7.1 + x)/3 > 5.3
Multiply both sides by 3.
6.3 + 7.1 + x > 15.9
x + 13.4 > 15.9
Subtract 13.4 from both sides.
x > 2.5
Answer: They need more than 2.5 inches.

what does i2x + 3(x - 5) = 20 equal
Answer:
x=7
Step-by-step explanation:
2x+3(x-5)=20
2x+3x-15=20
5x-15=20
5x=35
x=7
Answer:
x = 5
Step-by-step explanation:
2x + 3(x - 5) = 20
simplify
5x - 5 = 20
get the variable and the number on different sides
5x - 5 + 5 = 5x
20 + 5 = 25
5x = 25
now divide each side by 5
5x / 5 = x
25 / 5 = 5
x = 5
