Chicken eggs can be categorized as large if they weigh at least 2 ounces. Clare weighs 48 large eggs and finds that they have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces. Interpret 0.08 ounces in this situation.

Answers

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

A ball is thrown vertically upward. After t seconds, its height h, in feet, is given by the function LaTeX: h\left(t\right)=-16t^2+64th ( t ) = − 16 t 2 + 64 t. How many seconds will it take the ball to reach its maximum height?

Answers

Answer:

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.

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.

Answers

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.

Answers

Answer:

B: 4,599 inches

Step-by-step explanation:

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

What is a Cylinder?

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

A jar contains 10 red marbles, 8 green marbles, 5 blue marbles, and 6 white marbles. What is the probability that a randomly selected marble is not green?

Answers

Answer:

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 next model sports car will cost 5.2% more than the current model. The current model costs $55,000. How much will the price increase in dollars? What will be the price of the next model?

Answers

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.
