The ages (in years) and heights (in Inches) of all pitchers for a baseball team are listed. Find the coefficient of variation for each of the two data sets. Then compare the
results.
***data set in picture attached***

CV heights= __% (Round to one decimal place as needed.)

Answer:

B

Step-by-step explanation:

2x+8=9

you want to isolate the variable so you subract 8 from both sides

2x=1

now you want x by itself so you divide by 2 on both sides

x=1/2 or x=0.5

Answer: y= -1x - 5  

Step-by-step explanation:

The equation has to be in slope-intercept form which uses the formula

y=mx+b   where m is the slope and b is the y-intercept.

So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.

the x coordinate is -7  and the y coordinate  is 2

2 = -1(-7) + b    

2 = 7  + b  

-7   -7

b = -5  the y intercept is -5

Now the equation will be y= -1x - 5

The length  of the missing side is 7 yards

Hope this helps! Plz award Brainliest : )

The answer is 7yd.

I got this answer by simply looking at the line parallel to it, which would be 16yd. I subtracted 16yd - 9yd = 7yd.

Answer:

k = - 11, 5

Step-by-step explanation:

By distance formula:

[tex] \sqrt{ \{ {k - ( - 3) \}}^{2} + \{5 - ( - 1) \}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(5 + 1)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(6)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + 36 } = 10 \\ \\ (k + 3)^{2} + 36 = {10}^{2} \\ ..(squaring \: both \: sides) \\ {k}^{2} + 6k + 9 + 36 = 100 \\ {k}^{2} + 6k + 45 - 100 = 0 \\ {k}^{2} + 6k - 55 = 0 \\ {k}^{2} + 11k - 5k - 55 = 0 \\ k(k + 11) - 5(k + 11) = 0 \\ (k + 11)(k - 5) = 0 \\ k + 11 = 0 \: or \: k - 5 = 0 \\ k = - 11 \: or \: k = 5 \\ \\ \huge \red { \boxed{k = \{ - 11, \: 5\}}}[/tex]

There are two solutions for [tex]k[/tex]: 5 and -11.

In this case, we must use the Length Equation for Line Segment to solve for [tex]k[/tex], whose formula is described below:

[tex]l = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex] (1)

Where:

[tex](x_{A}, y_{A})[/tex] - Coordinates of the initial endpoint.

[tex](x_{B}, y_{B})[/tex] - Coordinates of the final endpoint.

[tex]l[/tex] - Length of the line segment.

If we know that [tex](x_{A}, y_{A}) = (-3, -1)[/tex], [tex](x_{B}, y_{B}) = (k, 5)[/tex] and [tex]l = 10[/tex], then the equation is expanded into this form:

[tex](k+3)^{2}+[5-(-1)]^{2} = 100[/tex]

[tex]k^{2}+6\cdot k + 9 + 36 = 100[/tex]

[tex]k^{2} + 6\cdot k -55 = 0[/tex]

The roots of this Second Order Polynomial are determined by Quadratic Formula:

[tex]k = 5[/tex] or [tex]k = -11[/tex].

There are two solutions for [tex]k[/tex]: 5 and -11.

Answer:

The probability of an event occurring depends on the sample space and the frequency of the event

permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6

Step-by-step explanation:

The probability of an event occurring depends on the sample space and the frequency of the event

The  total outcomes of rolling a pair of fair dice would be = ( total outcome of  single dice A * total outcome of  single Dice B ) = 6 * 6 = 36. and this is because the Two dice are independent of each other. hence there is a higher variability in the determining the possibility of a particular number ( 1,2,3,4,5,6) showing up when a pair of dice is rolled due to the larger sample space. permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6

Answer:

Entonces la proporción es 1/2

Step-by-step explanation:

Aquí, en esta pregunta, queremos encontrar la razón que divide al segmento AB en la razón (0,5 / 3).

Usamos la fórmula de división interna para esto;

Sea la relación m / n Matemáticamente, la fórmula de división que da lugar a (0,5 / 3) es la siguiente;

(x, y) = mx2 + nx1 / (m + n), my2 + ny1 / (m + n)

En este caso particular;

(x1, y1) = (-2,3)

(x2, y2) = (4, -1)

(x, y) = (0,5 / 3).

Así que hagamos las sustituciones; (0,5 / 3) = m (4) + n (-2) / (m + n), m (-1) + n (3) / (m + n)

(0,5 / 3) = (4m -2n) / (m + n), (-m + 3n) / m + n.

Por tanto, equiparemos términos;

4m-2n / (m + n) = 0

4m -2n = 0

4m = 2n

n = 4 m / 2

n = 2 millones •••••••• (i)

(3n -m) / (m + n) = 5/3

3 (3n -m) = 5 (m + n)

9n - 3m = 5m + 5n

9n -5n = 3m + 5m

4n = 8m

n = 8 m / 4 n = 2m ••••••• (ii)

Podemos ver que ambos son iguales;

n = 2 m 1 = 2m / n

divide ambos lados por 2

m / n = 1/2.

1. get the gcf of 3 and 8

3×8=24

2.the new equation would be this:

3. the value of x would be 6 because 3×6=18.

3×5=15 wouldnt make sense because it is is smaller than 16.

Step-by-step explanation:

It is given that,

6.3% of the 6,540,000 Indiana residents were listed as Hispanic or Latino in 2012. We need to find the no of people for this.

Using the concept of percentage as follows :

[tex]\dfrac{6.3}{100}\times 6540000 =412020[/tex]

Hence, there would be 412020 people.

Hey there! I'm happy to help!

These are corresponding angles since they both connect a parallel line and the transversal. This means they are congruent and have the same value. So, we can set up the following equation.

8x-8=5x+25

Subtract 5x from both sides.

3x-8=25

Add 8 to both sides.

3x=33

Divide both sides by 3.

x=11.

Answer:

x = 11

∠B = 80

Step-by-step explanation:

∠A = ∠B

where

∠A = 8x - 8°

∠B = 5x + 25°

8x - 8° = 5x + 25°

8x - 5x = 25 + 8

3x = 33

x = 33/3

x = 11

plugin x into ∠B = 5x + 25°

∠B = 5x + 25°

∠B = 5(11) + 25°

∠B = 80

Answer:

  (-2, 3)

Step-by-step explanation:

You can divide the inequality by 2:

  -4 < x -2 < 1

And add 2.

  -2 < x < 3

Expressed in interval notation, this is (-2, 3).

Answer:

The coordinates of point B are : (-1, 1)

Step-by-step explanation:

[tex]\frac{-7+x^{2} }{2} = -4\\\frac{1+y^{2} }{2} =1[/tex] You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.

Then you create the equations [tex]-7 + x^{2} = -8\\1 + y^{2} = 2[/tex] you substitute -7 for +7 and add 7 to -8 which gives -1 ([tex]x^{2}[/tex]) and subtract 1 from 2 which gives you 1 ([tex]y^{2}[/tex])

To check your answer use the midpoint formula [tex]\frac{-7+-1}{2} =\frac{-8}{2} =-4\\\frac{1+1}{2} =\frac{2}{2} =1[/tex] which gives you your midpoint (-4,1)

Answer: Lin is the most consistent and I would want to have them on my team.

Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since

range = max - min

So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.

Answer:

Normally Distributed.

Explanation:

After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" not an answer. "correlated with a second set of data" is also wrong since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.
