Answer:

Probability

Step-by-step explanation:

Answer: Hi!

To solve this equation, we need to isolate the x. To do this, we will use inverse operations.

The inverse operation for multiplication is division (3 is being multiplied by x,) so we will divide 3 on both sides:

3x/3 = x

21/3 = 7

Our equation now looks like this:

x = 7

You have nothing left to simplify, so you're done!

Hope this helps!

Answer:

7

Step-by-step explanation:

Divide each term in  3 x  =  21  by  3 .  

21/3 = 7

Answer:

The numbers would be placed inside of natural numbers

Step-by-step explanation:

Such number would be placed inside natural numbers.

Integers are whole numbers and their opposites. This means that an integer can be a negative number.

Whole numbers are counting numbers, including Zero and excluding negative numbers. Therefore whole numbers are greater than or equal to 0

Natural numbers are counting numbers excluding Zero and Negative numbers.

From the above definitions, we can agree that natural numbers exists in whole numbers and also exists in integers, but neither of the two exists in natural numbers.

We can then say that

Natural numbers is a subset of whole numbers which is a subset of integers.

Natural numbers < Whole numbers < Integers.

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

4x + 5 = 25

Subtract 5 from each side

4x + 5-5 = 25-5

4x = 20

Answer:

y = (2 x)/3 + 1/4

Step-by-step explanation:

Solve for y:

Divide both sides by -12:

Answer: y = (2 x)/3 + 1/4

Answer:

0.08 ounces is interpreted as the Mean Absolute Deviation and this means that

the various weights of each of the 48 eggs deviates from the mean of the egg (2.1 ounces)by 0.08 ounces.

Step-by-step explanation:

Mean Absolute Deviation of a data set is defined as the distance or the deviation between a given data set and the calculated mean.

Mean Absolute Deviation tells us about how much a data set varies from it's mean.

From the above question, we are told that after weighing 48 eggs we have a mean of 2.1 ounces and mean deviation of 0.08 ounces

Therefore this means that the various weights of each of the 48 eggs deviates from the mean of the egg (2.1 ounces)by 0.08 ounces

Answer:

-15 ft or 15 ft below sea level

Step-by-step explanation:

He started at +8 ft.

Then he went 23 ft down, that is -23 ft.

8 ft + (-23 ft) = 8 ft - 23 ft = -15 ft

Answer: -15 ft

We're adding n and m onto k to get P. Undo these operations to isolate k. So we subtract m from both sides

P = k+n+m

P-m = k+n+m-m

P-m = k+n

and we subtract n from both sides

P-m = k+n

P-m-n = k+n-n

P-m-n = k

Answer: Hi!

So, to find the answer to this question, we would substitute the variables in the equation with the x, y coordinated of the solution.

x = 2 and 4 = y

Our equation now looks like this:

4 = 17(2) - 12

4 = 34 - 12

4 = 22

This is not a true statement! Therefore, the point (2,4) cannot be a solution for this equation.

Answer: The price increase = $2,860.

The price of the next model will be $57,860.

Step-by-step explanation:

Given: The next model sports car will cost 5.2% more than the current model.

Current model costs $55,000.

Price increase = 5.2%  of (Cost of current model)

= (0.052) x ($55000)

= $ 2860

So, the price increase = $2860.

Price of the next model = Cost of current model +  price increase

= $(55000+2860)

= $ 57,860

Hence, the price of the next model will be $57,860.

Answer:

B: 4,599 inches

Step-by-step explanation:

The volume of the empty space in cylindrical container is V = 4,599 inches³

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the radius of the sphere be r₁ = 13 inches

So , the volume of the sphere V₁ = ( 4/3 )πr³

V₁ = ( 4/3 ) ( 3.14 ) ( 13 )³

V₁ = 9,198.106 inches³

Let the radius of the cylinder be r₂ = 13 inches

Let the height of the cylinder be h = 26 inches

So , Volume of Cylinder = πr²h

V₂ = 3.14 ( 13 )² x 26

V₂ = 13,797.16 inches³

So , the volume of the empty space V = V₂ - V₁

V = 13,797.16 inches³ - 9,198.106 inches³

V = 4,599 inches³

Hence , the volume of empty space is 4,599 inches³

Probability (not green) = 21 / 29

Step-by-step explanation:

Given:

Number of red marble = 10

Number of green marble = 8

Number of blue marble = 5

Number of white marble = 6

Find:

Probability (not green)

Computation:

Total marble = 10 + 8 + 5 + 6

Total marble = 29

Probability (not green) = 1 - (Probability of green marble))

Probability (not green) = 1 - (8 / 29)

Probability (not green) = 21 / 29

The expression that has a value of 10 is (10 + 10) divide (5 - 3)

To do this, we simply test the options

We have:

Option (A)

(10 + 10) divide (5 - 3)

Evaluate the sum and the difference

(10 + 10) divide (5 - 3) = 20 divide 2

Evaluate the quotient

(10 + 10) divide (5 - 3) = 10

Hence, the expression that has a value of 10 is (10 + 10) divide (5 - 3)

Answer/Step-by-step Explanation:

a. Order the marks scored by James from the least to the largest:

11, 12, 13, 13, 16, 17, 17, 18, 19, 19, 20

To find the interquartile range for James Marks, first find the median, Q1, and then Q3.

The median is the middle value, which is the 6th value in the data set.

11, 12, 13, 13, 16, [17], 17, 18, 19, 19, 20

The median = 17

The Q1 is the middle value from the median to your left, while Q3 is the middle value from the median to the right.

11, 12, (13), 13, 16, [17], 17, 18, (19), 19, 20

Q1 = 13

Q3 = 19

Interquartile range (IQR) = [tex] Q_3 - Q_1 = 19 - 13 = 6 [/tex]

b. Sunil has a median score of 17, which is the same has that of James, however, the interquartile range value for that of Sunil is higher (8) than that of James (6).

The higher the interquartile range, the much variation there is in a set of data. Which can imply inconsistency.

Therefore, James has more consistent marks because his marks has lesser variation.

c. The new marks of the tests which are 16, 20, 18, and 10, would not change the initial median score. This is because, 10 and 16 would fall under the initial median value of 17, while 18 and 20 would fall above the median value of 17. The data set would still be divided into 2, with 17 still being the median.

Therefore, the new median is 17.

The time it will take for the ball to reach maximum height of 64 feet is 2 seconds

Step-by-step explanation:

The given equation for the height, h, in feet the ball reaches is given by the function;

h(t) = -16·t² + 64·t

To reach maximum height, [tex]h_{max}[/tex], we have;

At [tex]h_{max}[/tex], we have;

[tex]\dfrac{\mathrm{d} h}{\mathrm{d} t} = 0[/tex]

[tex]\dfrac{\mathrm{d} \left (-16\cdot t^{2} + 64\cdot t \right )}{\mathrm{d} t} = 0[/tex]

Which gives;

64 -32·t = 0

64 = 32·t

t = 64/32 = 2 seconds

Therefore, it will take 2 seconds for the ball to reach maximum height

The maximum height reached is given as follows;

h(2) = -16×2² + 64×2 = 64 feet

The time it will take for the ball to reach maximum height of 64 feet is 2 seconds.
