The box plot for the data is attached in the image.

A box plot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.

The term "box plot" comes from the fact that the graph looks like a rectangle with lines extending from the top and bottom.

The minimum is the lowest number in the data set.

18

The median is the middle number.

27

The first quartile (Q1) is the median of the lower half of data which lies at 25% of the data.

The third quartile (Q3) is the median of the upper half of data which lies at 75% of the data.

The maximum is the highest number in the data set; it is 38

This is what a typical box plot looks like and it is attached in the image.

The volume of the cylinder is 157 unit³.

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Given: B= 25π, h= 2 units

Base area= 25π

πr²=  25π

r²=25

r=±5 units

Now, Volume of cylinder= πr²h

                                         = 3.14* 5* 5* 2

Answer:

B. About 2% of the boys are eligible to be a small forward on the team

Step-by-step explanation:

Recall : 1 feets = 12 inches

Point guard = 6’2" – 6’6" tall = 74 - 78 inches

Mean = 70 ; Standard deviation = 4

Z = (x - mean) / standard

P(x < 74) = (74 - 70) / 4 = 1

P(x < 78) = (78 - 70) / 4 = 2

0.97725 - 0.84134 = 0.13591

Small forward : 6'6" = 78 inches

P(x ≥ 78) = (78 - 70) / 4 = 2

P(z ≥ 2) = 0.02275 = 2.275% about 2%

Centre : 6'8" = 80

P(x ≥ 80) = (80 - 70) / 4 = 2.5

P(z ≥ 2.5) = 0.0062097 = 0.62%

About 2% of the boys are eligible to be a small forward on the team. Then the correct option is B.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

A high school basketball coach is selecting his team.

The minimum and maximum height requirements are as follows:

Point Guard: Small Forward: Center:

6’2" – 6’6" tall at least 6’6" tall at least 6’8" tall

The heights of the Lincoln High School boys have a normal distribution with a mean height of 70 inches and a standard deviation of 4 inches.

The value of the z-score will be

[tex]z = \dfrac{x - \mu }{\sigma}[/tex]

[tex]P(x < 74) = \dfrac{74-70}{4} = 1 \\\\P(x < 78) = \dfrac{78-70}{4} = 2[/tex]

0.97725 - 0.84134 = 0.13591

Small forward: 6'6" = 78 inches

[tex]P(x \geq 78) = \dfrac{78- 70 }{4} 2\\\\\\P(z \geq 2) = 0.02275 = 2.275 \%[/tex]

Centre: 6'8" = 80 inches

[tex]P(x \geq 80) = \dfrac{80- 70 }{4} 2\\\\\\P(z \geq 2.5) = 0.0062097= 0.62 \%[/tex]

Answer:

1/125, -1/125, -125, 1

Step-by-step explanation:

1. 5^-3 = 1/5^3 = 1/125

2. -5^-3 = 1/-5^3 = -1/125

3. Take the answer above, its the first part of the question; (-1/125)^-1 = -125

4. Any real number raised to the 0th power is one.

Answer:

See below

Step-by-step explanation:

[tex]5^{-3}[/tex] - When you are raising a number to a negative power, it is the same as dividing 1 by that power when it is positive. So, [tex]5^{-3}[/tex] can be written as: [tex]\frac{1}{5^{3}}[/tex].

[tex]5^3[/tex] is 125, so we can substitute that in to get: [tex]\frac{1}{125}[/tex]

[tex]-5^{-3}[/tex] - This expression is the same as the one before, but it is negative. This means we can say [tex]-5^{-3} = -\frac{1}{125}[/tex]

[tex](-5^{-3})^{-1}[/tex] - We can start by writing [tex]-5^{-3}[/tex] as [tex]-1 * 5^{-3}[/tex]. Now, we can distribute the exponent -1, and simplify. Remember when raising a power in parenthesis to another power, you multiply them:

[tex](-1 * 5^{-3})^{-1}\\(-1)^{-1} * (5^{-3})^{-1}\\-1*5^3\\-1*125\\-125[/tex]

[tex](-5^{-3})^0[/tex] - We can start by writing [tex]-5^{-3}[/tex] as [tex]-1 * 5^{-3}[/tex]. Now, we can distribute the exponent 0, and simplify:

[tex](-1*5^{-3})^0\\(-1)^0 * (5^{-3})^0\\1 * 1\\1[/tex]

Step-by-step explanation:

The values shown are ...

  8/3 ≈ 2.67

  √5 -5 ≈ -2.76

  -π ≈ -3.14

Answer:

x=1

Step-by-step explanation:

6x+2=9x-1

You first want to isolate the variable to one side, so subtract 6x and 9x

2=9x-1

-6x

2=3x-1

Now you want to get rid of the constant, so add 1 to the other side

2=3x

+1

3=3x

Now divide both sides by 3 to remove the 3 from x.

3/3=3x/3

1=x

Answer:

x = [tex]3\sqrt{13}[/tex] = 10.8

Step-by-step explanation:

Both problems are done the same way.  I will do the first one and you do the second one.  OK?

Move the radius x to make a right triangle.  The 6 unit segment bisects the chord.  So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle.   Now,

[tex]6^{2} + 9^{2} = x^{2}[/tex]

[tex]x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}[/tex]= 10.8

None of the answer choices are to the nearest tenth.  So, I am confused about that.

In  the second problem, the answer should be 11.2

Answer: 9/2

Answer:

shen's new area will be 1200 ft ^ 2

It will be 2 times the original

Donna should increase the length by 5 times

Step-by-step explanation:

Original length = 40

New length = 30 x 4 = 120

Original width = 20

New width = 20 x 5 = 100

120 x 100 = 12000 ft^2

12000/600 = 20

It will be 20 times larger

For Donna:

ex:

length = 1

width = 2

Area = 2

He wants it to be 15 times 2

Lisa says increase 4 times

2 x 3 = 6

30/6 = 5
