Answer:

g = \(\frac{4}{3}\)

Step-by-step explanation:

4 - \(\frac{1}{12}\) g - 2 = \(\frac{3}{2}\) g + 1 - \(\frac{5}{6}\) g

multiply through by 12 ( the LCM of 12, 2 and 6 ) to clear the fractions

48 - g - 24 = 18g + 12 - 10g

- g + 24 = 8g + 12 ( subtract 8g from both sides )

- 9g + 24 = 12 ( subtract 24 from both sides )

- 9g = - 12 ( divide both sides by - 9 )

g = \(\frac{-12}{-9}\) = \(\frac{12}{9}\) = \(\frac{4}{3}\)

The probability that the other child is also a girl, given that one of them is a girl, is 2/3 or approximately 0.6667.

To determine the probability that the other child is also a girl given that one of them is a girl, we need to consider the possibilities of the gender combinations for Alice's two children.

Let's denote the gender of the first child as G (girl) and B (boy), and the gender of the second child as G' and B'.

There are four possible combinations for the gender of the two children: GG, GB, BG, and BB.

However, we are given that one of the children is a girl. This eliminates the BB combination since we know both children cannot be boys.

Thus, we are left with three possible combinations: GG, GB, and BG.

Out of these three combinations, two of them involve at least one girl: GG and GB. This means there is a 2 out of 3 chance that the other child is a girl.

Therefore, the probability that the other child is also a girl, given that one of them is a girl, is 2/3 or approximately 0.6667.

The area of the table is approximately 651 square inches.

What is Area ?

Area is a measure of the size of a two-dimensional shape or surface, such as a rectangle, circle, or triangle. It is expressed in square units, such as square inches, square feet, or square meters.

Let's use the Pythagorean theorem to find the length of the table top:

Substituting the given values, we get:

40*40 = \(length^{2}\) + 21*21

Simplifying and solving for length, we get:

\(length^{2}\)= 1600 - 441

\(length^{2}\) = 961

length = 31 inches (rounded to the nearest inch)

Now that we know the length and width of the table, we can find the area by multiplying them together:

area = length x width

area = 31 x 21

area = 651 square inches (rounded to the nearest inch)

Therefore, the area of the table is approximately 651 square inches.

Answer:

Part A

The first thing we must do for this case is to rewrite both expressions.

We have then:

1/2 (7x + 48) = (7/2) x + 24

- [1 / 2x - 3] + 4 (x + 5) = - (1/2) x + 3 + 4x + 20 = (7/2) x + 23

Answer:

We note that the first expression is greater than the second for all values of x.

Part B:

A new expression that is greater than both written expressions is:

(7/2) x + 25

For all values of x, this expression is always greater.

Answer:

(7/2) x + 25

Step-by-step explanation:

To solve this problem, we can use the binomial distribution formula, which calculates the probability of a certain number of successes (in this case, business travelers who say their reason for the trip was an internal company visit) out of a given number of trials (950 business travelers). The formula is:
P(x) = (n choose x) * p^x * (1-p)^(n-x)

Where:
- P(x) is the probability of getting x successes
- n is the number of trials (950 business travelers)
- x is the number of successes we're interested in (between 133 and 171)
- p is the probability of success (19% or 0.19)

To find the probability that between 133 and 171 business travelers say their reason for the trip was an internal company visit, we need to calculate the sum of the probabilities of getting 133, 134, 135,..., 170, 171 successes. This can be quite tedious to do by hand, but fortunately, we can use a calculator or a statistical software program to do it for us.

Assuming that we use a calculator or software, we can find that the probability of getting between 133 and 171 business travelers who say their reason for the trip was an internal company visit is approximately 0.919. This means that out of three random paragraphs of this length, it's likely that one would show the probability of the business travelers who say their reason for the trip was an internal company visit to be between 133 and 171.

The 98% confidence interval for the average age of all students at this college is an option (C) which is (24.301, 25.699)

Confidence interval:

A range of values such that the population parameter can be expected to contain for the given confidence level is termed the confidence interval. In other words, it can be defined as an interval estimate of the population parameter which is calculated for the given data based on a point estimate and for the given confidence level.

Moreover, the confidence level indicates the possibility that the confidence interval can contain the population parameter. Usually, the confidence level is denoted by . The value is chosen by the researcher. Some of the most common confidence levels are 90%, 95%, and 99%.

The Confidence interval for the mean is:

x ± \(z_{a/2}\) (s/√n)

Step: 1

Here, the confidence level is 0.98.

For (1-α) = 0.98

α = 0.02

From the Standard Normal Table, the required

\(Z_{0.02}\)

The value is obtained below:

That is,

P(Z≤z) = 0.02

The procedure for finding the z-value is listed below:

Considering the definition of zeros of a function, the zeros of the function f(t)= (t-5)² - 9 are 2 and 8.

The points where a polynomial function crosses the axis of the independent term (x) represent the so-called zeros of the function.

That is, the zeros of a function are those values ​​of x for which the expression is equal to 0. Graphically, the roots correspond to the abscissa of the points where the parabola intersects the x-axis.

Considering the function f(t)= (t-5)² - 9, if the zeros of a function are those values ​​of x for which the expression is equal to 0, you get:

(t-5)² - 9= 0

Solving:

(t-5)² = 9

t-5 = √9

t-5= ±3

Then:

t-5= 3

t= 3 +5

t= 8

and

t-5= -3

t= -3 +5

t= 2

There are two distinct sets of all four quantum numbers with n = 4 and ml = -2:

(n = 4, l = 2, ml = -2, ms = +1/2)

(n = 4, l = 2, ml = -2, ms = -1/2)

To determine the number of distinct sets of all four quantum numbers (n, l, ml, and ms) with n = 4 and ml = -2, we need to consider the allowed values for each quantum number based on their respective rules.

The four quantum numbers are as follows:

Principal quantum number (n): Represents the energy level or shell of the electron. It must be a positive integer (n = 1, 2, 3, ...).

Azimuthal quantum number (l): Determines the shape of the orbital. It can take integer values from 0 to (n-1).

Magnetic quantum number (ml): Specifies the orientation of the orbital in space. It can take integer values from -l to +l.

Spin quantum number (ms): Describes the spin of the electron within the orbital. It can have two values: +1/2 (spin-up) or -1/2 (spin-down).

Given:

n = 4

ml = -2

For n = 4, l can take values from 0 to (n-1), which means l can be 0, 1, 2, or 3.

For ml = -2, the allowed values for l are 2 and -2.

Now, let's find all possible combinations of (n, l, ml, ms) that satisfy the given conditions:

n = 4, l = 2, ml = -2, ms can be +1/2 or -1/2

n = 4, l = 2, ml = 2, ms can be +1/2 or -1/2

The probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918

We can solve this problem by using the Central Limit Theorem, which states that the sample mean of a sufficiently large sample size will be normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In this case, we are given that the population mean is 11 inches and the population standard deviation is 3 inches. We are also given that we have a sample size of 4.

First, we need to calculate the standard error of the mean (SE) using the formula

SE = σ / sqrt(n)

where σ is the population standard deviation and n is the sample size.

SE = 3 / sqrt(4) = 1.5

Next, we need to standardize the sample mean using the formula

z = (x - μ) / SE

where x is the sample mean, μ is the population mean, and SE is the standard error of the mean.

z = (13 - 11) / 1.5 = 1.33

Finally, we can use a standard normal distribution table or calculator to find the probability that a standard normal variable is greater than 1.33. The probability is approximately 0.0918.

In the given word problem, the rate of change is the change in the cost of the ice cream concerning the change in the number of scoops.

That is, the rate of change is the ratio of the change in the cost of ice cream and the change in the number of scoops. Let's first calculate the initial rate of change or slope of the given deal: When we buy a waffle cone, the cost is $3, and we can buy one scoop of ice cream for $1.50.So, for one scoop of ice cream, the total cost would be 3 + 1.50 = $4.50.

We can represent the cost of one scoop of ice cream with the help of a linear equation: y = mx + b. Here, the slope or the rate of change, m = Change in cost of ice cream/ Change in the number of scoops= 1.5/1= 1.5Therefore, the rate of change of the ice cream with respect to the number of scoops is $1.50/scoop.

Between 20 and 40 units per hour, the long-run average cost curve exhibits constant returns to scale. The statement that indicates between 20 and 40 units per hour, the long-run average cost curve exhibits constant returns to scale. This is option B.

In microeconomics, the long-run average cost (LRAC) is a method of showing the average expense per unit for a given level of production input. It is the cost of producing goods per unit using a specified number of inputs, such as labor and capital.

Long-run average cost is the average cost per unit of production after the company has adapted its production scale fully. As a result, the term "long-run" denotes a period in which all of the firm's inputs are variable.

The cost structure's shape is represented by the long-run average cost curve. The curve is determined by dividing the cost of producing goods by the number of goods produced. It aids in identifying the production rate at which a firm may generate the most output at the lowest cost.The long-run average cost curve depicts how the average cost of production varies with scale.

The curve might be downward-sloping, indicating economies of scale, flat, implying constant returns to scale, or upward-sloping, indicating diseconomies of scale, based on the company's production methods.

Hence, the answer is B.
