Divide:

Divide, in its simplest form, means to divide into two or more equivalent portions, spaces, groups, or divisions. Divide, in plain English, means to provide the entire thing to a group in equal portions or to divide it into equal pieces. Let's say a square is divided into two triangles with equal areas by a diagonal. A division operation may or may not provide an integer as the outcome. The outcome may occasionally take the form of decimal numbers.

Answer: $3.75

Step-by-step explanation:

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.

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

∠E is 74° because it is alternate to the given angle of 74°.

∠E is and the 74° angle are alternate interior angles. Alternate interior angles are a pair of angles on the inner side of two parallel lines. But the angles should be on the opposite sides of the transversal. A transversal line is a straight line that intersects two or more parallel lines.

So here, ∠E and 74° lie on the inner sides of two parallel lines on the opposite sides of the transversal.

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.

Therefore, there are 3060 number of elements in the sample space for this experiment.

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

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:

1) b = 17/4

2) x = -3/5

Step-by-step explanation (question one):

Step 1: Simplify both sides of the equation.

3b +9 + −5b + 3 = −14 +6b +−8

(3b +−5b) +(9 +3)=(6b) +(−14 + −8) (Combine Like Terms)

−2b +12 = 6b −22

Step 2: Subtract 6b from both sides.

−2b +12 −6b = 6b −22 −6b

−8b +12 = −22

Step 3: Subtract 12 from both sides.

−8b +12 −12 = −22 −12

−8b = −34

Step 4: Divide both sides by -8.

(-8b/-8) = (-34/-8)

Step 5: Get your Answer

b = 17/4

Step-by-step explanation (question two):

Step 1: Simplify both sides of the equation.

2x +5 + −4x +8 = (5)(5) +(5)(6x) + −12x (Distribute)

2x +5 + −4x +8 = 25 +30x + −12x

(2x+−4x) + (5+8) = (30x +−12x) +(25) (Combine Like Terms)

−2x +13 = 18x +25

Step 2: Subtract 18x from both sides.

−2x +13 −18x= 18x +25 −18x

−20x +13 = 25

Step 3: Subtract 13 from both sides.

−20x +13 −13 = 25 −13

−20x=12

Step 4: Divide both sides by -20.

(-20x/-20) = (12/-20)

Step 5: Get your Answer

x = -3/5

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. The area of  a rectangle A = L×W

Where,

A = Area of the rectangle which is 7y^2 - 3y

L = Length  which is unknown

W = Width of the rectangle which is y

Substituting,

7y^2 - 3y = L × y

divide through by y

(7y^2 - 3y)/y = L
