The volume of the cylinder will be 138.2 inches³

From the information, the shape has a height 3 in more than 4 times the radius of the cylinder's base.

The volume of a cylinder is equal to V = πr²h

where

r is the radius of the base

h is the height

In the problem, h = 3 + 4r

r = 2 inches

To calculate h, h = 3 + 4 × 2

h = 11 inches

The volume of a cylinder is equal to:

v = πr²h

v = π × 2² × 11

v = 44π inches³

V = 138.2 inches³

The bearing from point point A to point B is given as follows:

57º.

From the text in this problem, the bearing from point B to point A is given as follows:

237º.

To obtain the inverse bearing, that is, the bearing from point A to point B, we must subtract the bearing from point B to point A given in this problem by 180º, as follows:

237 - 180 = 57º.

Hence the bearing from point point A to point B is of 57º.

The missing expense values are given as follows:

The missing expenses are obtained applying the proportions in the context of this problem.

The rent expense of $2,400 is 40% of the total expenses, hence the total expenses are given as follows:

0.4x = 2400

x = 2400/0.4

x = $6000.

The utilities expenses are 5% of that, hence:

0.05 x 6000 = $300.

The labor expenses are 15% of the total, hence:

0.15 x 6000 = $900.

The supplies expenses are 30% of the total, hence:

The point slope form of the equation of the line through the given point with the given slope is y - 4 = -2(x + 1).

The equation in slope intercept form is y = -2x + 2.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

At data point (-1, 4), a linear equation of this line can be calculated in point-slope form as follows:

y - y₁ = m(x - x₁)

y - 4 = -2(x - (-1))

y - 4 = -2(x + 1)

Next, we would rewrite the equation in slope-intercept form as follows;

The length of the sides of the original square is -2.1 unit²

An equation is a mathematical expression that contains two or more numbers and variables linked together by mathematical operations such as exponents, multiplication, division, addition, subtraction and so on.

Let l represent the original side and A represent the original area. Hence:

Area = length * length

A = l * l

A = l²

The side of a square is increased by 5 units, the area is increased by 4 square units. Hence:

A + 4 = (l + 5) * (l + 5)

A + 4 = l² + 10l + 25

If 84% of products come off the line ready to ship to distributors, then the probability of a product being within specifications is 0.84.

Since we are selecting 12 products randomly from the line each hour, the number of products within specifications (x) follows a binomial distribution with parameters n = 12 and p = 0.84.

Using a binomial cumulative distribution function (CDF), we can calculate the probability that x is less than a certain value. For example, if x is less than 7, the probability of this outcome would be considered unusual and the production line should be repaired.

A skewed distribution is one in which the data deviates from the normal distribution and has a longer tail on one side. In the case of the number of siblings, the distribution is skewed to the right, meaning that there are more students with higher numbers of siblings. The mean of 1.8 siblings and standard deviation of 0.7 sibling indicate the average and spread of the number of siblings in the entire student population of the high school.

Answer: .

Step-by-step explanation:

With equal probability and flip it, given that the flip was heads, the probability that I flipped the two-headed coin is: 0.6667

Let's call the event of flipping the fair coin "F" and the event of flipping the two-headed coin "T".

The probability of flipping heads given that we flipped the fair coin is 1/2, so P(heads | F) = 1/2.

The probability of flipping heads given that we flipped the two-headed coin is 1, so P(heads | T) = 1.

The probability of flipping the fair coin is 1/2 and the probability of flipping the two-headed coin is 1/2, so P(F) = P(T) = 1/2.

Using Bayes' Theorem, we can find the probability that we flipped the two-headed coin given that the flip was heads:

Plugging in the values, we get:

So the probability that we flipped the two-headed coin given that the flip was heads is 2/3, or approximately 0.6667.
