The volume of the rectangular prism is 31.5 in³.

From the diagram, we know that the height of the rectangular prism is 9 cubes. We can see the length is 7 cubes and the width is 4 cubes. Each cube is half an inch. Therefore we multiply every side by 1/2.

Height = 9 × (1/2)

Height = 4.5 inches

Length = 7 × (1/2)

Length = 3.5 inches

Width = 4 × (1/2)

Width = 2 inches

Volume = L × W × H

Volume = 3.5 × 2 × 4.5

Volume = 31.5 inches³

Answer:B

Step-by-step explanation:

a) The sample space for four flights selected at random, with arrival status "O" for on-time and "L" for late, is given as {OOOO, OOOL, OOLO, OOLL, OLOO,  OLOL, OLLO, OLLL, LOOO, LOOL, LLOO, LLOL, LLLO, LLLL}.

b) The probability that a randomly selected flight is from Airline A and on-time, denoted as P(A), is calculated by multiplying the probability of being on-time for Airline A (75/100) with the proportion of flights operated by Airline A out of the total (320/1000), resulting in P(A) = 24/100.

c) The probability that a randomly selected flight is either from Airline C or on-time, denoted as P(C), is obtained by dividing the sum of flights on-time (700) and flights operated by Airline C (240) by the total number of flights (1000), giving P(C) = 94/100.

d) The probability that a flight is from Airline B given that it is late, denoted as P(B | L), is computed by multiplying the proportion of late flights (300/1000) with the probability of being from Airline B (35/100), resulting in P(B | L) = 77/300.

e) The probability that a flight is late given that it is from Airline A, denoted as P(L | A), is calculated by multiplying the proportion of flights on-time for Airline A (25/100) with the proportion of flights operated by Airline A (320/1000), resulting in P(L and A) = 8/100. Therefore, P(L | A) = 1 - P(A | L) = 11/15.

Answer:

Step-by-step explanation:

All these amount of money are based on Dan's initial amount, which is x. Ben had 7 more than Dan, so Ben's amount of money is x + 7. Kaden has 4 more than Ben, so Kaden's amount of money is 4 + (x + 7) which is x + 11. So here's the breakdown so far:

Dan: x

Ben: x + 7

Kaden: x + 11

Now it looks like Kaden is the favorite and got another 20 from his mom, so his amount became x + 31. After Dan spends a dollar, making his amount x - 1, Kaden had 9 times what Dan had. Now we have finally:

x + 31 = 9(x - 1) and

x + 31 = 9x - 9 and

40 = 8x so

x = 5.

Dan originally had $5, Ben originally had $12, and Kaden originally had $16

The required arc length of sector VW is 8\(\pi\).

Given that, in a circle U, radius  UV = 9 and  central angle of sector m∠VUW = 160°.

Answer:

83,900

Step-by-step explanation:

100/33560 = 250/x

There are 2 options to solve. You can cross multiply:

100x = 33560*250

100x = 8,390,000 Divide by 100

x = 83,900

I also see that you start with 100 naira and want to see the value at 250 naira.

250 is 2.5 times 100. If you take the original 33560 fr and multiply that by 2.5, you will get 83,900.

The figure can be divided into a triangle and a rectangle.

The area of a triangle is 10 sq inches.

The area of a rectangle is 80 sq inches.

The total area of the figure is 90 sq inches.

The area of a rectangle is the product of its length and width.

The perimeter of a rectangle is the sum of the lengths of all the sides.

The figure can be divided into a triangle and a rectangle.

The height of the triangle is 2 inches and the base is 10 inches.

We know the area of a triangle is (1/2)×base×heiht.

The distribution of the given function is a uniform distribution.

A strictly increasing function is the one which increases continuously in a given interval. If f-1(u) is a strictly increasing function of u, then the distribution of f-1(u) is the same as that of u. This is because a strictly increasing function preserves the rank ordering of its input, so if u-1 and u-2 are two random variables with a uniform distribution on the interval (0,1), then the rank order of f-1(u-1) and f-1(u-2) will be the same as the rank order of u-1 and u-2. Since the uniform distribution is defined by the rank order of its values, this means that the distribution of f-1(u) is also uniform on the interval (0,1).

The quality control specialist should use a t-distribution for estimating the mean clarity rating of the new batch of glass sheets being produced using a sample of 18 sheets of glass.

The quality control specialist at a plate glass factory must estimate the mean clarity rating of a new batch of glass sheets being produced using a sample of 18 sheets of glass.

Since the actual distribution of this batch is unknown, but preliminary investigations show that a normal approximation is reasonable, the specialist should use a t-distribution.
1. The sample size (n) is 18, which is relatively small.
2. The population standard deviation (σ) is unknown.
In such cases, the t-distribution is more appropriate than the z-distribution, chi-square distribution, or f distribution.

The t-distribution is a statistical distribution that is used when the sample size is small, and the population standard deviation is unknown.
The z-distribution is used when the population standard deviation is known, and the sample size is large enough (typically, n > 30).
The chi-square distribution is used for testing the goodness-of-fit of a distribution or for testing the independence between two categorical variables.
The f distribution is used for comparing the variances of two populations.

It is not suitable for estimating the mean clarity rating in this case.
In conclusion, the quality control specialist should use a t-distribution for estimating the mean clarity rating of the new batch of glass sheets being produced using a sample of 18 sheets of glass.

The conclusion about p using an absolute value inequality would be that |p - 72| ≤ 4. This means that the difference between the true proportion p and the estimated proportion 72% is no more than 4%.

In other words, p is most likely to fall within the range of 68% to 76%, as determined by the margin of error in the statistical polling calculation. This emphasizes the importance of recognizing and accounting for the potential for error and uncertainty in estimating percentages and proportions in various fields, including politics and marketing.
To describe the conclusion about the percentage (p) in statistical polling using an absolute value inequality, you can use the margin of error (4% in this example) as a way to create the inequality.
In this case, we have a poll result of 72% and a margin of error of 4%. So, the absolute value inequality would be:
|p - 72%| ≤ 4%
This inequality shows that the difference between the true percentage (p) and the poll result (72%) should be less than or equal to the margin of error (4%). In other words, the true percentage (p) is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%).

The volume of a cone with 4 faces, which is a square with side length a and height h, can be calculated using the formula V = (π * a^2 * h) / 12.

To find the volume of a cone with 4 faces, which is essentially a square with side length a and height h, we can follow these steps:

1. The volume of a cone is given by the formula V = (1/3) * π * r^2 * h, where r is the radius of the circular base and h is the height.

2. In this case, the base of the cone is a square with side length a. Since all sides of a square are equal, the radius of the circular base is half of the side length, which is a/2.

3. Therefore, we can substitute the values in the formula: V = (1/3) * π * (a/2)^2 * h.

4. Simplifying further, we get V = (1/3) * π * (a^2/4) * h.

5. Multiplying the terms, we have V = (π * a^2 * h) / 12.

In step 1, we used the formula for the volume of a cone.

In step 2, we determined the radius of the circular base of the cone.

In step 3, we substituted the values in the formula.

In step 4, we simplified the expression.

In step 5, we multiplied the terms to obtain the final volume formula.

The phrase "number of values for which a certain condition holds" is referred to as multiplicity. The phrase, for instance, can be used to describe the magnitude of the totient valence function or the frequency with which a given polynomial equation has a root at a specific location.

Let z_0 be a root of a function f, and let n be the least positive integer n such that f^((n))(z_0)!=0. Then the power series of f about z_0 begins with the nth term,

f(z)=sum_(j=n)^infty1/(j!)(partial^jf)/(partialz^j)|_(z=z_0)(z-z_0)^j,

and f is said to have a root of multiplicity (or "order") n. If n=1, the root is called a simple root '

The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.

It's crucial to understand the concept of multiplicity in order to correctly count without mentioning exceptions (for example, double roots counted twice). Thus, "counted with multiplicity" is used.

This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.

Hence ,Multiplicity means the quality or state of being multiple or various. and

the number of components in a system (such as a multiplet or a group of energy levels)

The equation of line whose x-intercepts is 12 and y- intercept is 4 is

3x + y = 36.

According to the given question.

We have a equation of line.

ax + by = c.

Also, x-intercept is 12 and y intercept is 4.

As we know that,the x-intercept for any curve is the value of the x coordinate of the point where the graph cuts the x-axis and y coordinate is zero.

And, the y-intercept is the point where the graph intersects the y-axis and the x-coordinate is zero.

Therefore, we have two points (12, 0) and (0, 4).

So, the equation of line from the two point s(12, 0) and (0, 4) is given by

(  y - 0) = (4 - 0/0 - 12)(x -12)

⇒ y = 4/-12(x -12)

⇒ y = -3(x -12)

⇒ y = -3x + 36

⇒ 3x + y = 36

By comparing the given equation of line ax + by = c with the above equation we get

a = 3, b = 1 and c = 36.

Hnce, the equation of line whose x-intercepts is 12 and y- intercept is 4 is 3x + y = 36.

The statement that when algebraic or numerical fractions are added or subtracted, the result is a single fraction is True.

For addition or subtraction of algebraic or numerical fractions, the denominator has to be the same for all terms in the equation.

For common denominator,

Suppose 2 numerical fractions are being added which have a common denominator: 3/5 + 1/5

The resultant fraction will be 4/5, which is a single fraction

For algebraic fractions, considering the denominators are common, such as 3x/5 + 4x/5 = 7x/5

The result is also a single fraction.

For different denominators,

Suppose 2 numerical fractions are being subtracted which have different denominators such as, 5/9 – 3/7

In this case, the least common multiple for the denominators are calculated: 9*7= 63, and the opposite numerators are multiplied to the opposite denominators

Therefore, (5*7 – 3*9)/63 = (35 – 27)/63 = 8/63, which gives us a single fraction.

The process is same for algebraic fractions, for example,

4x/7 – 3x/5 = (4x*5 – 3x*7)/35 = (20x – 21x)/35 = -x/35, which is also a single fraction.
