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

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:

The answer is 95

Step-by-step explanation:

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:

f(8) = 195

Step-by-step explanation:

When the x if f(x) is replaced with an 8, this just means that it is the eighth term. All you really have to do is replace every X in the function to find the answer.

f(8) = 3 + 3(8)²

f(8) = 3 + 3(64)

f(8) = 3 + 192

f(8) = 195

Diego's bounce = 2x

If Diego's bounce = 8

Then ;

2x = 8

x = 8/2

x = 4

Ben's bounce = x + 8

Answer:

  y-intercept (0, -6)

  x-intercept (-8, 0)

Step-by-step explanation:

You're writing the coordinates of the points where the line crosses the axes.

The y-intercept is where the line crosses the y-axis. The y-coordinate there is -6. Because it is the y-axis, the x-coordinate is 0. Written as an ordered pair, the y-intercept is (0, -6).

The x-intercept is where the line crosses the x-axis. The x-coordinate there is -8. Because it is the x-axis, the y-coordinate is 0. Written as an ordered pair, the x-intercept is (-8, 0).

here's the solution,

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

                                         = 157 unit³

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.

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]
