Step-by-step explanation:

Volume of cylinder: pi × r² × h

1) 3.14 × 20² × 100

125,600 cm³

2) 3.14 × (118/2)² × 30

327,910.2 m²

Answer:

D.  127

Step-by-step explanation:

Because our spinner is split up evenly 8 ways, we a have a 1/8th chance of getting 6 with any given spin. We will want to pick the number that is the closest to one 1/8th of 1104 from our options at the right.

Let's check them one by one. Note that 1/8 as a decimal is .125, if you are using a calculator to do this problem, decimals will be fastest and we'll work with those here.

A) 291/1104 = .264

B) 117/1104 = .106

C) 209/1104 = .189

D) 127/ 1104 = .115

Our closest number to .125 (ie, 1/8th) is .115. or 127 out of 1,104 spins.

Answer:

D, 127

Step-by-step explanation:

it would be d because if the spinners each have equal spots then you can divide it by 8. which gets you 138, but that isn't an option and its probability so its always around a number. so the closest one is 127 or D

Answer:

f'(1) = 2

Step-by-step explanation:

f(x) = 2x^2 -2x +3

Take the derivative

f'(x) = 2 * 2x - 2 * 1

f'(x) = 4x -2

f'(1) = 4(1) -2

      =4-2

       =2

Answer:

Linda was 37.8 m away when the arrow hit the ground

Step-by-step explanation:

We are given that The arc of the arrow can be modeled by the equation :

[tex]y = -0.02x^2 + 0.65x + 4[/tex]

Where x is the horizontal distance (in meters) from Linda

y is the height (in meters) of the arrow.

Now we are supposed to find How far from Linda does the arrow hit the ground

So, y must be 0 when the arrow hits the ground

So, Substitute y = 0 in the equation :

[tex]y = -0.02x^2 + 0.65x + 4\\0 = -0.02x^2 + 0.65x + 4\\0.02x^2-0.65x-4=0\\0.02(x-37.79)(x+5.29)=0\\x=37.79,-5.29[/tex]

Since distance cannot be negative

So,Linda was 37.8 m away when the arrow hit the ground

Answer:

The answer is D.

Step-by-step explanation:

It have 5 different surface. I will name them as front, back, left, right and down. It's easier for you to see.

Front: 36*50= 1800

Back: 14*36=504

Left: 14*48/2=336

Right:14*48/2=336

Down:36*48=1728

Then, we add everything together and get the answer.

1800+504+336+336+1728=4702.

Answer:

960 cubes

Step-by-step explanation:

To find how many cubes of side 1 foot can be contained in the room, we have to find the volume of the storage room and then, divide by the volume of the cube.

The storage room is in the shape of a rectangular prism, hence, its volume is:

[tex]V = L * W * H[/tex]

where L = length

W = width

H = height

The dimensions of the storage room are:

10 feet wide, 12 feet long, and  8 feet high

Hence, its volume is:

[tex]V = 10 * 12 * 8 = 960 ft^3[/tex]

The volume of the cube of side 1 foot is:

[tex]V = S^3\\\\V = 1^3 = 1 ft^3[/tex]

Hence, the number of cubes that can be contained in the storage room is:

960 / 1 = 960 cubes

960 cubes can be stored in the storage room.

Final answer:

To find the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively, the GCD (greatest common divisor) can be used. The GCD between 60 and 8 is 4, and the GCD between 75 and 10 is 5. Thus, the largest number that satisfies the conditions is 4.

Explanation:

To find the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively, we can use the concept of the greatest common divisor (GCD). The GCD is the largest number that divides two or more numbers without leaving a remainder. To find the GCD, we can use the Euclidean algorithm.

First, we divide 60 by 8. The quotient is 7 and the remainder is 4. Then, we divide 8 by 4. The quotient is 2 and the remainder is 0. Since the remainder is 0, we stop here. Therefore, the GCD of 60 and 8 is 4.

Next, we divide 75 by 10. The quotient is 7 and the remainder is 5. Then, we divide 10 by 5. The quotient is 2 and the remainder is 0. Again, since the remainder is 0, we stop here. Therefore, the GCD of 75 and 10 is 5.

Therefore, the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively is 4.

Answer:

your answer is (1,-6)

Step-by-step explanation:

when a point is reflected in y-axis, then the y-co-ordinate remains same and then x-co-ordinate becomes the opposite of that number.

When you reflect a point across the y-axis, only the x-coordinate changes while the y-coordinate stays the same. For example:

(-x, -y) -> (x, -y)

So:

(-1, -6) -> (1, -6)

Answer:

Step-by-step explanation:

To solve the quadratic equation [tex]-x^2 + 8x = 7[/tex], we first convert it to standard form and identify the coefficients. Using the quadratic formula, we find the solutions to be x = -1 and x = 7.

To solve the given quadratic equation, [tex]-x^2 + 8x = 7[/tex], we first need to bring the equation to the standard form of a quadratic equation, which is [tex]ax^2 + bx + c = 0[/tex]. We can do this by subtracting 7 from both sides, resulting in [tex]-x^2 + 8x - 7 = 0[/tex].

Now the equation is in standard form, we identify the coefficients: a = -1, b = 8, and c = -7. Applying these to the quadratic formula, x = [-b ± [tex]\sqrt(b^2 - 4ac)[/tex]] / (2a), we get:

x = [-8 ± [tex]\sqrt((8)^2[/tex] - 4(-1)(-7))] / [2(-1)]

x = [-8 ± [tex]\sqrt(64 - 28)[/tex]] / -2

x = [-8 ± [tex]\sqrt(36)[/tex]] / -2

x = [-8 ± 6] / -2

Now, solving for x, we get two solutions:

x = (-8 + 6) / -2 = -1

x = (-8 - 6) / -2 = 7

Therefore, the solutions to the quadratic equation are x = -1 and x = 7.

Answer:

The mean of X, μₓ is 2

The standard deviation of X, σₓ is 1.3

Step-by-step explanation:

Here we have the expected value given by the following relation

Expected value = P(x) × n

Where:

P(x) = Probability that the event occurs

n = Number of times the event occurs

The probability of the dice showing 1  = 1/6

The number dice rolled = 12

Therefore, out of 12, the expected number of dice that show 1 in a turn = 12×1/6 = 2

The proportion, p of dice that show 1 = 1/6, hence the mean, μx = np

Standard deviation of a proportion,  [tex]\sigma _x =\sqrt{np{(1 - p)} }[/tex]

Where:

p = 1/6

n = 12

Hence;

μx = 12 × 1/6 = 2

[tex]\sigma _x =\sqrt{np{(1 - p)} } = \sqrt{12 \times \frac{1}{6} (1 - \frac{1}{6}) } = \sqrt{\frac{5}{3} } = 1.29099 \approx 1.3 \ to \ the \ nearest \ tenth[/tex]

Hence the mean and standard deviation of X are presented as follows;

The mean of X, μₓ = 2

The standard deviation of X, σₓ = 1.3.

Step-by-step explanation:

this is a trigonometry question, so we first draw a triangle with height 55 and angles 11.3 (degrees) and 78.7 (degrees). tan(11.3)=55/base, so the base would be 275.248 ft.

Answer:

D

Step-by-step explanation:

The outlier of 2 decreases the mean page count.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

If the outlier is included in the calculation of the median and mean, then it will affect the measures of central tendency.

However, if the outlier is excluded from the calculation, then it will not affect the measures of central tendency.

If the 2-page introduction chapter is an outlier on the higher side of the distribution, the outlier of 2 increases the mean page count more than the median page count.

If the 2-page introduction chapter is an outlier on the lower side of the distribution, the outlier of 2 decreases the mean page count more than the median page count.

therefore, The outlier of 2 decreases the mean page count.
