True or false don’t lie

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.

Complete Question

The Henderson Hawks minor-league baseball team is giving away baseballs an

game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your

work or explain your reasoning.

Answer:

They should give away 100 balls and 100 towels

Step-by-step explanation:

Let the number of balls = x

Let the number of towels = y

x + y = 200........ Equation 1

y = 200 - x

$3 × x + $2 × y = $5000

3x + 2y = 5000...... Equation 2

3x + 2(200 - x)= 5000

3x + 400 - 2x = 5000

Collect like terms

3x - 2x = 500 - 400

x = 100

Number of balls to be given away = 100

Note:

y = 200 - x

y = 200 - 100

y = 100

Number of towels to be given away = 100

Therefore, they should give away 100 balls and 100 towels

Answer: 0.54

Step-by-step explanatio;

We would have three in common out of 4 characteristics (4 out of 4 is not possible). There are 4 possible ways to share 3 out of 4 characteristics.

Denoting the characteristics as {M,C,Si,Sh} so P(B2={1,1,1,0}|B1={1,1,1,0}) is the probability that box 2 shares its first three characteristics with box 1 given that box one has characteristics

We now have

P(B2 has 3 elements in common with B1)=P(B2={1,1,1,0}|B1={1,1,1,0})xP(B1={1,1,1,0})+P(B2={1,1,0,1}|B1={1,1,0,1})xP(B1={1,1,0,1})+P(B2={1,0,1,1}|B1={1,0,1,1})xP(B1={1,0,1,1})+P(B2={0,1,1,1}|B1={0,1,1,1})xP(B1={0,1,1,1})

P(B2 has 3 elements in common with B1)=(4x5x24+3x4x30+2x3x40+1x2x60)1120x119= 0.084

which is close enough to the value from the simulation code (modified to count the number of 3-ties)

Now, I use the same reasoning to compute:

P(B2 has 2 or more elements in common with B1)=(19x20x6+11x12x10+9x10x12+14x15x8+7x8x15+5x6x20)1120x119= 0.54

Equation: (2-1)((3-1)+(4-1)+(5-1)) + (2)((3)+(4)) + (12) = 35 with a total of 119 possibilities.

answer: 35/119

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.

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.

Answer:

2x-3

Step-by-step explanation:

Answer:

y = 2x + 3

Step-by-step explanation:

Parallel lines must have the same slope, in the given equation, the slope is 2, so the slope for the parallel line must also be 2, so that eliminates answer choices B and D.

Now to choose between answer choices A or C, you can just plot the given point (-3, -3) into each equation and see which one fits. Answer A seems to be the correct answer.

Hope this helps!

Answer: F(x) = x

Step-by-step explanation:

y = mx + b is the base equation

m = the slope slope equals the increase of y over x

b = the y intercept

y = 1/1 x + 0

so y = x

or f(x) = x

Answer:

The slope of the points (-3,2) (-5,-2) is 2

The slope of the points (7,1) (1,-7)​ is 4/3

Step-by-step explanation:

Use rise over run (y2 - y1) / (x2 - x1)

Plug in the points given and find the slopes:

(y2 - y1) / (x2 - x1)

(-2 - 2) / (-5 + 3)

-4/-2

= 2

Find the next slope:

(y2 - y1) / (x2 - x1)

(-7 - 1) / (1 - 7)

-8/-6

= 4/3

The slope of the points (-3,2) (-5,-2) is 2

The slope of the points (7,1) (1,-7)​ is 4/3

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.
