A student bought a piece of hard candy that is in the shape of a sphere. The candy has a radius of 3 centimeters.
​Which of the following is closest to the volume of the piece of candy?
​ (Use 3.14 for π.)

Answer:

Step-by-step explanation:

The set of values are 2, 4, 7, 8, 9.

The mean of these values are [tex]\frac{2 + 4 + 7 + 8 + 9}{5} = \frac{30}{5} = 6[/tex].

The mean of the squares of the differences of these numbers and the mean is [tex]\frac{(6 - 2)^{2} + (6 - 4)^{2} + (6 - 7)^{2} + (6 - 8)^{2} + (6 - 9)^{2}}{5} = \frac{(4)^{2} + (2)^{2} + (-1)^{2} + (-2)^{2} + (-3)^{2}}{5} = \frac{34}{5} = 6.8[/tex].

In order to get the value of the standard deviation, we need to square-root the value of 6.8.

Hence, the standard deviation of the data set is [tex]\sqrt{6.8} = 2.607680962081[/tex] ≅2.6076809621.

Answer:

Correct answer is 2.9.

Took the test.

Answer:

Part A:  For no solution ⇒ 3x + 9 + 4x + x = 8x + 0

Part B:  For one solution ⇒ 3x + 9 + 4x + x = 0 * x + 1

Part C:  For infinitely many solutions ⇒ 3x + 9 + 4x + x = 8x + 9

====================================

Step-by-step explanation:

Part A:

3x + 9 + 4x + x = 8x

8x + 9 = 8x ⇒ Subtract 6x from both sides,

9 = 0 which is absurd and hence the equation has no solution.

=====================================

Part B:

3x + 9 + 4x + x = 0 * x + 1

∴ 3x + 9 + 4x + x = 1

8x + 9 = 1 ⇒ Subtract 9 from both sides.

8x = 1 - 9 = -8 ⇒ Divide both sides by 8.

x = -1      ⇒ this is the only solution.

======================================

Part C:

3x + 9 + 4x + x = 8x + 9

8x + 9 = 8x + 9

Subtract 8x from both sides,

9 = 9, both sides are balanced which means, the equation has infinitely many solutions.

Answer:

y=2.5x+3650

Step-by-step explanation:

since you don't know the amount of units sold you make that x

you do know that the company has to pay a set amount each month for utilities and salaries. 350+3300

put this together, and you get the equation:

y=2.5x+3650

y=total expenses

2.5= price per unit

x= total units sold

3650=amount payed each month for utilities, and salaries

Final answer:

The hockey player must score 20 goals to make the same money as the first contract.

Explanation:

In order to make the same amount of money as the first contract, the hockey player must calculate the number of goals required. Let's assume the player needs to score 'x' goals.

For the first contract, the total salary would be 50000 + 1000x. For the second contract, the total salary would be 40000 + 1500x.

Equating the two salaries, we get:

50000 + 1000x = 40000 + 1500x

Subtracting 1000x from both sides, we get:

50000 = 40000 + 500x

Subtracting 40000 from both sides, we get:

10000 = 500x

Dividing both sides by 500, we get:

x = 20

So, in order to make the same money as the first contract, the player must score 20 goals.

Answer:

This is true

Step-by-step explanation:

When looking at x itself it is just ONE x. 1x=x, the 1x isn't necessary to have so it is shown as x. So looking at x/3 you could say it is also 1x/3 which would still be the same if it were 1/3x. Both would still be considered one-third OF x.

The answer is "[tex]3x=3x[/tex]"

Equating:

[tex]\to \frac{x}{3} = \frac{1}{3}x\\\\x=?[/tex]

Cross multiplying the given expression:

[tex]\to \frac{x}{3} = \frac{1}{3}x\\\\\to 3x=3x[/tex]

Therefore, the given statement is "True"

To find the number of non-soda cans collected by Miguel, subtract the number of soda cans from the total number of cans he collected.

Miguel collected a total of 150 aluminum cans for recycling. The question asks how many of these cans were not soda cans.

So, the number of non-soda cans would be 150 - x.

Answer:

C

Step-by-step explanation:

The equation of the function g(x) after the transformation is g(x) = kn(x - 3).

A vertical asymptote of a function is the vertical line x = c such that the function tends to approach to infinity as the value of x approaches c.

Given a function f(x) = = ln (x).

The vertical asymptote of the logarithmic function is x = 0.

If the vertical asymptote of the new function is x = 3, this means that the function is shifted to the right by 3 units.

When f(x) is shifted to right by k units, new function is f(x - k).

So the function g(x) is,

g(x) = f(x - 3) = ln (x - 3).

Hence the correct option is C.

Answer:

16 cups

Step-by-step explanation:

64 × .25=16

When the total amount of ice cream, 64 cups, is divided by the scoop size, which is 1/4 cup, it gives us 256. Therefore, Jerry can get 256 scoops of ice cream from each bucket.

The amount of ice cream in each bucket is given as 64 cups. Jerry's scoop holds 1/4 cup of ice cream. In order to figure out how many scoops Jerry can get from one bucket, we need to divide the total amount of ice cream (64 cups) by the amount Jerry's scoop holds (1/4 cup).

To carry out this operation, we divide 64 by 1/4 which is equivalent to multiplying 64 by the reciprocal of 1/4 (i.e., 4/1 or simply 4). This results in 64 * 4 = 256. So, Jerry can get 256 scoops of ice cream out of each bucket.

Answer:

P(red marble) = 6÷15

Step-by-step explanation:

First, we add all of it we get 15.

Now the probability of getting a red marble will be = number of favorable outcomes ÷ total out comes.

Here the favorable outcomes to red is 6,and the total outcome is 15.

So it is 6÷15.

Now we took one marble. And kept it away.

Now the total number of outcomes are 15-1=14

Now the favorable outcomes for green is 7,snd total outcomes are 14.

So the probability is 7÷14.

Remember don't subtract the one marble u took in every similar question. Do it only if it is told to keep away the first marble you took.

i believe it is this

Final answer:

The original price of the motorbike is calculated by dividing the final price of $2160 by 0.9, which represents the 90% price paid after a 10% discount. The original price of the motorbike was $2400 before the discount was applied.

Explanation:

The question asked us to calculate the original price of a motorbike before a 10% discount was applied and the final price came down to $2160. To do this, we recognize that the final price ($2160) is 90% of the original price because a 10% discount was given. Thus, if we let the original price be 100%, we can find it by dividing the final price by 0.9 (which represents 90%).

Here's the step-by-step calculation:

Express the discount as a decimal: 10% = 0.1.

Determine the percentage of the original price paid: 100% - 10% = 90% = 0.9.

Calculate the original price: Original Price = Final Price / 0.9.

Substitute the known value: Original Price = $2160 / 0.9.

Perform the division to find the original price: Original Price = $2400.

The original price of the motorbike was therefore $2400 before the discount.

k = -3/2

Step-by-step explanation:

Write the equation of the line.

Replace x and y with the x- and y-coordinates, respectively, of the point.

Solve for k.

y = kx + 5

Replace x with -6. Replace y with 14.

14 = k(-6) + 5

Solve for k.

14 = -6k + 5

9 = -6k

k = -9/6

k = -3/2

Answer:

-7/6

Step-by-step explanation:

You know that x = -6 and y = 14 so you can plug them into your equation like this:

12= k(-6) + 5

Then solve for k

12-5 = 7

k = -7/6

  (x -a)^2 + y^2 = 2a^2

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

Here r^2 is the square of the distance between the center and the point on the circle. That can be found using the distance formula:

  d^2 = r^2 = (x2-x1)^2 +(y2 -y1)^2 = (0-a)^2 +(-a-0)^2 = 2a^2

Filling in the above formula with (h, k) = (a, 0) and r^2 = 2a^2, we find the equation to be ...

  (x -a)^2 +y^2 = 2a^2

To calculate the location of the diver after 12 1/2 seconds, use the formula: location = initial location - (rate of descent * time). The location of the diver after 12 1/2 seconds is -28.

To calculate the location of the diver after 12 1/2 seconds, we can use the formula: location = initial location - (rate of descent * time). Since the diver is descending at a rate of 2 1/4 per second, we can plug in the values to calculate their location after 12 1/2 seconds.

Initial location: 0 (surface of the water)

Rate of descent: 2 1/4 per second

Time: 12 1/2 seconds

Using the formula, we have: location = 0 - (2 1/4 * 12 1/2)

Calculating the expression, we find that the location of the diver after 12 1/2 seconds is -28.

Option 1: 6a = 420 requires division property of equality to be solved

We will see all the options one by one.

Option 1:

[tex]6a = 420[/tex]

In this option, 6 is multiplied with the variable so we have to divide the whole equation by 6 to find the value of a.

So we will use "Division property of Equality"

Dividing both sides by 6

[tex]\frac{6a}{6} = \frac{420}{6}\\a=70[/tex]
