Answer:

512

Step-by-step explanation:

To determine how many 1" x 1" x 1" cubes can fit into an 8" x 8" x 8" box, we need to calculate the volume of the box and then divide it by the volume of a single cube.

The volume of the box is calculated by multiplying its length, width, and height:

Volume of the box = 8" x 8" x 8" = 512 cubic inches.

The volume of a single cube is 1" x 1" x 1" = 1 cubic inch.

To find out how many cubes can fit, we divide the volume of the box by the volume of a single cube:

Number of cubes = Volume of the box / Volume of a single cube

Number of cubes = 512 cubic inches / 1 cubic inch

Number of cubes = 512

Therefore, 512 cubes that are 1" x 1" x 1" can fit into an 8" x 8" x 8" box.

The probability p that the perdimos is also a female is 17/120

Conditional Probability is the possibility or likelihood of an event or outcome happening, based on the existence of a previous event or outcome.

How to determine this

When there were 17 females in class

And 20 male in class

When randomly selected, the female are 52

And males are 68

To calculate the selected volunteer is a student of the class.

= 20 + 17/52 + 68

= 37/120

To calculate the probability that the selected student is female.

= 17/52 + 68

Domain:  {-24, -12, -8, 9, 14, 50}

Range:  {23, 69, 83, 92, 97, 32}

Step-by-step explanation:

For a function like f(x), each coordinate is in the form (x, f(x)) aka (x, y)

Since our x-coordinates are -24, -12, -8, 9, 14, and 50, the domain of f(x) is {-24, -12, -8, 9, 14, 50}

Since our f(x) or y-coordinates are 23, 69, 83, 92, 97, and 32, the range is {23, 69, 83, 92, 97, 32}

The greatest common factor of two terms given as 21x⁴ and 49x³ is equal to  7x³.

To find the greatest common factor (GCF) of two terms, we need to find the highest factor that is common to both terms. In this case, we have 21x⁴ and 49x³.

To find the factors, we can break each term down into its prime factors:

21x⁴ = 3 * 7 * x * x * x * x

49x³ = 7 * 7 * x * x * x

The common factors are 7 and x³. To find the GCF, we multiply these common factors together:

GCF = 7  * x³

GCF = 7x³

Segment BF is 36 will be the accurate statement.

A triangle known to be similar if the ratio of similar sides of the triangle is equal to a constant.

From the given triangle, the following expression is true:

EC/FC = AC/BF+FC

Substitute the given parameters into the formula to have:

20/30 = 24+20/BF+30

20/30 = 44/BF+30

2/3 = 44/BF + 30

2(BF+30) = 132

2BF + 60 = 132

2BF = 132 - 60

2BF = 72

The estimated error in the calculated area is approximately 3.2ft²

To estimate the error in the calculated area of a square, use linear approximation or differentials.

The area of a square is given by the formula A = s², where s represents the length of a side.

Calculate the area of the square using the given side length of 16 ft:

A = (16 ft)²

A = 256 ft²

Now, let's consider the possible error in the side length, which is ±0.1 ft. Treat this error as a change in the side length (Δs) and use linear approximation or differentials to estimate the corresponding change in the area (ΔA).

Using linear approximation, express the change in the area as:

ΔA ≈ 2s Δs

Substituting the values:

ΔA ≈ 2(16 ft)(0.1 ft)

ΔA ≈ 3.2 ft²

Therefore, the estimated error in the calculated area is approximately 3.2ft².

The z- score of a person who scored 280 on the exam can be found to be - 0. 5.

A z-score indicates how many standard deviations an element is from the mean.

The formula is:

Z = ( X - μ ) / σ

The details here are:

X = 280, μ = 300, and σ = 40

The z - score is therefore :

Z = (280 - 300) / 40

= -20 / 40

= -0.5

In conclusion, the z - score of a person who scored 280 on the exam is -0.5. This means that their score is half a standard deviation below the mean.

The probability that it is raining if the flight has been delayed is 0.07, or 7%.

We can use the following formula to calculate the probability that it is raining if the flight has been delayed:

P(Rain|Delayed) = P(Rain and Delayed) / P(Delayed)

We are given that P(Rain) = 0.07 and P(Delayed) = 0.18. We can also use the fact that P(Rain and Delayed) = P(Rain) * P(Delayed):

= 0.07 * 0.18

= 0.0126.

Substituting these values into the formula, we get:

P(Rain|Delayed) = 0.0126 / 0.18 = 0.07
