Answer:

  C.  6 times as many as c is 72

Step-by-step explanation:

You want to know if c = 12, which statement is true.

We can substitute 12 for c in each expression and write it as a math equation. That makes it easier to see if it is true.

  12 = 5×4

  12 = 20 . . . . . false

  27 = 12×3

  27 = 36 . . . . . false

  6×12 = 72 . . . . . TRUE

  8 + 12 = 15

  20 = 15 . . . . . false

Each board must be within how many inches of 15 is l' actual = (15±0.03) inch, l" actual = (15±0.03) inch.

The number of unit cubes it would take to completely fill the prism with no gaps between unit cubes is 72

From the question, we are to determine how many unit cubes it would take to completely fill the prism with no gaps between unit cubes.

To do this, we will calculate the volume of rectangular prism

Assuming each cube is 1 cubic unit

Then,

From the top view,

The length of the rectangular prism = 9 units

The width of the rectangular prism = 2 units

From the Right-side view,

The height of the rectangular prism = 4 units

Thus,

The volume of the rectangular prism = 9 × 2 × 4

Volume of the rectangular prism = 72 cubic units

Now,

Number of cubes required to fill the rectangular prism = Volume of the prism / Volume of the cubes

Number of cubes required to fill the rectangular prims = 72 / 1

Number of cubes required to fill the rectangular prims = 72

Hence, the number of unit cubes it would take is 72

According to the combination method, the number of elements in the sample space for this experiment is 3060

Combination method:

Basically, the mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter

Given,

A person eating at a cafeteria must choose 4 of the 18 vegetables on offer.

Here we have to calculate the number of elements in the sample space for this experiment.

While we looking into the given question, we have identified the following things,

They are

Total number of available vegetables = 18

Number of choices we have made = 4

Therefore, here the value of n = 18 and the value of x = 4,

Therefore, according to the ncx formula, it can be written as,

=> ¹⁸n₄ = 18! / 4! (18 - 4)!

=> ¹⁸n₄ = 18! / 4! (14)!

=> ¹⁸n₄ = 3060.

This is what i put for the hw and i got 100% on it. If you want you can just write a bunch of random equations that look like they relate to the question and then just write and circle the answer, which is exactly what i did

Answer:

Step-by-step explanation:

1) 3b + 9 - 5b + 3 = -14 + 6b - 8, for b?

→ 3b + 9 - 5b + 3 = -14 + 6b - 8

→ -2b + 12 = 6b - 22

→ -2b - 6b = -22 - 12

→ -8b = -34

→ b = -34/-8

→ [ b = 17/4 ]

Hence, the value of b is 17/4.

2) 2x + 5 - 4x + 8 = 5(5 + 6x) - 12x, for x?

→ 2x + 5 - 4x + 8 = 5(5 + 6x) - 12x

→ -2x + 13 = 25 + 30x - 12x

→ -2x - 18x = 25 - 13

→ -20x = 12

→ x = 12/-20

→ [ x = -3/5 ]

Hence, the value of x is -3/5.

Answer:

y = 2x + 5

Step-by-step explanation:

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sinθ

sec θ = 1/cosθ

cot θ = 1/tanθ

Given data ,

Let the triangle be ΔABC and ∠B = 90°

The angle ∠A = 21°

θ = 21°

The value of the hypotenuse = 22

The value adjacent to the right angle is BC = x

From the trigonometric functions , we know that

sin θ = opposite / hypotenuse

So ,

sin θ = x / 22

Answer:

The cost of 6 cans of soup is 3.75

Step-by-step explanation:

12 = 7.50

1 can = x

12x = 7.50

We need to find the cost of 1 can. So we divide 7.50 by 12.

x = 0.625

Then multiply by 6.

0.625 x 6 = 3.75

As a result the cost of 6 cans of sup is $3.75

"95% confidence interval" means that there is a 95% chance that the true fraction falls within the computed confidence interval.

Confidence Intervals: Confidence intervals are the range of estimates for unknown parameters.

Confidence intervals are more than just a range of estimated values. It also tells you how stable the estimates are. A stable estimate is an estimate that has approximately the same value if the study is repeated. An unstable estimate is one that would vary from one sample to another.

The confidence interval determines the range that one can be certain that contains the true mean of the population.

This means that, The 95% confidence means, there is a 95% chance that the true proportion will be in the calculated confidence interval or 95 percent confidence interval, you have a 5 percent chance of being wrong.

Hence, the true statement that represents "95% confidence interval" is chance of true fraction of sucess.

For the given graph, the gradient of the given blue line in the graph is equal to 2.

As given in the question,

For the given graph,

Consider two pairs of coordinates on the blue line of the given graph,

( x₁ , y₁ ) = ( 2, 2 )

( x₂ , y₂ ) = ( 3, 4 )

Gradient is nothing but slope of the line

Formula to calculate the gradient of the given blue line of the graph is given by:

Gradient = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substitute the value in the formula we get,

Gradient = ( 4 - 2 ) / ( 3 - 2 )

              = 2 / 1

              = 2

Binomial probability distribution = 0.0231

The following is the probability using the binomial distribution:

P(X = 24) = 0.0231.

In terms of the normal approximation to the binomial, it is discovered that:

Part 2: C. Yes, because np(1-p)≥10, the normal distribution can be used.

Part 3: The likelihood is: 0.0227.

Part 4: The distinction is: 0.0004.

Binomial probability distribution

The following is the mass function for the probability of exactly x successes:

P(X = x) = [tex]C_{n,x}[/tex].[tex]P^{x}[/tex].[tex](1-P)^{n-x}[/tex]

[tex]C_{n,x}[/tex] = [tex]\frac{n!}{x!(n-x)!}[/tex]

In which the following parameters are defined:

The number of trials in the experiment is n.

The probability of success on a single trial of the experiment is given by p.

The values of these parameters are given in the context of this problem as follows:

n = 59, p = 0.3, X = 24.

Hence the probability is:

P(X = x) = [tex]C_{n,x}[/tex].[tex]P^{x}[/tex].[tex](1-P)^{n-x}[/tex]

P(X=24) = [tex]C_{59,24}[/tex].[tex](0.3)^{24}[/tex].[tex](0.7)^{35}[/tex] = 0.0231

In the context of this problem, the condition for the approximation is verified as follows:

np = 59 x 0.3 = 17.7 ≥ 10.

n(1 - p) = 59 x 0.7 = 41.3 ≥ 10.

Step-by-step explanation:

This graph is in terms of x.

By solving a linear equation, we will see that the value of the greater integer is 12.

Let's define x as the smaller integer, then the greater integer is:

x + 2

(is +2 because is the next consecutive even integer)

We know the sum of an integer and 4 times the next consecutive even integer is 58.

So we can write the linear equation:

x + 4*(x + 2) = 58

x + 4x + 8 = 58

5x = 58 - 8

5x = 50

x = 50/5

x = 10

Then the greater integer is x + 2 = 10 + 2 = 12
