Answer:
Triangular pyramid and Rectangular prism
Step-by-step explanation:
There are several different uses of the formula V = BH. For example, we used the formula V = BH for a cylinder, a rectangular prism, and a triangular pyramid. But be careful! All of the elements in the formulas don't mean the same! I really hope this helps you a bit!
Volume of the Right triangular prism and rectangular prism can be found by using the formula V= B×h
What is Volume?Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface
What is Base area?It refers to the area of one of the bases of a solid figure.
Given,
Volume V= B×h
Where B is the Base area and h is the height
Volume of the Right triangular prism and rectangular prism can be found by using the given formula V = B×h. Because two identical shapes (base) facing each other with a height h
But we cannot find the volume of the Rectangular pyramid, triangular pyramid and mid by using the given equation because this formula is used to find the volume of a geometric prism or cylinder.
Hence, Volume of the Right triangular prism and rectangular prism can be found by using the formula V= B×h

What is assumed by the homogeneity of variance assumption?
a. The two samples have equal variances
b. The two sample variances are not equal.
c. The two populations have equal variances
d. The two population variances are not equal
Homogeneity of variance assumption assumes that the two populations have equal variances, so the correct answer is option c, "The two populations have equal variances.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The homogeneity of variance assumption assumes that the two populations have equal variances. Therefore, the correct answer is option c, "The two populations have equal variances."
This assumption is often made in statistical tests that compare the means of two groups, such as the t-test.
When the variances of the two populations are equal, it allows for more precise estimates of the standard error and can improve the accuracy of the test results.
However, if the variances are not equal, it can lead to biased and unreliable results.
In such cases, alternative methods, such as Welch's t-test or the Brown-Forsythe test, can be used to adjust for unequal variances.
Hence, homogeneity of variance assumption assumes that the two populations have equal variances, so the correct answer is option c, "The two populations have equal variances.

20 applicants from a pool of 90 applications will be hired. How many ways are there to select the applicants who will be hired?
The ways are the \(C_{20} ^{90}\) which are we there to select the applicants who will be hired with the help of combination.
According to the statement
we have to find that the number of ways are there to select the applicants who will be hired.
So, For this purpose, we know that the
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Here we use the combination.
And from the given information:
20 applicants from a pool of 90 applications will be hired.
And according to this the combination becomes:

Tisha earned $4,000.00 from a summer job and put it in a savings account that earns 10% interest compounded annually. When Tisha started college, she had $5,969.00 in the account which she used to pay for tuition. How long was the money in the account?
The money was in the account for approximately 4 years before Tisha used it to pay for tuition.
Let's use the terms provided and the formula for compound interest to find out how long the money was in the account.
The compound interest formula is: A = P(1 + r/n)^(nt)
Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the time the money is invested or borrowed for, in years
In your case, we have:
A = $5,969
P = $4,000
r = 10% = 0.10 (converted to decimal)
n = 1 (interest is compounded annually)
We need to find 't'. We can plug the values into the formula and solve for 't':
$5,969 = $4,000(1 + 0.10/1)(1*t)
Now, we can simplify and solve for 't':
Divide both sides by $4,000:
1.49225 = (1.10)t
Take the natural logarithm (ln) of both sides:
ln(1.49225) = ln((1.10)t)
Apply the power rule for logarithms:
ln(1.49225) = t * ln(1.10)
Solve for 't':
t = ln(1.49225) / ln(1.10)
t ≈ 4

asuming 14 people, 5 men and 9 women, how many ways can they sit in a circle such that every man is diametricaly opposite a woman
There are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.
In this problem, we want to find the number of ways to seat 14 people in a circle such that every man is diametrically opposite a woman.
Since every man must be diametrically opposite a woman, we can pair each man with one woman. There are 5 men and 9 women, so there are 5 pairs. We need to find the number of ways to seat these 5 pairs of people in a circle.
To do this, we can first seat one pair in any position. Then, we can seat the second pair anywhere but opposite the first pair. This gives us 11 positions for the second pair. Continuing in this way, we see that there are 11 * 6 * 5 * 4 * 3 = 7920 ways to seat the 5 pairs of people in a circle.
So, there are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

Alice has just discovered base 10 cake! She is delighted with how powerful it is. One day, after nibbling on the cake, Alice realizes she is 1 mile tall. Having her head in the sky makes her think about space travel. She decides she wants to visit the moon, which is about 239,000 miles from the earth. How many more ounces of base 10 cake should Alice eat so the top of her head just touches the moon? Give your answer to the nearest hundredth of an ounce.
Answer:
5.38 ounces
Step-by-step explanation:
Given that :
Alice height = 1 mile
Distance of earth to moon = 239000 miles
Number of base 10 cakes required so they Alice's head just touches the moon ;
Using the relation :
Distance = height per ounce * 10^number of ounces
Height per ounce = 1 mile ;
Let number of ounces = n
Hence,
239000 = 1 * 10^n
239000 = 10^n
Take log of both sides
Log(239000) = n
5.3783979 = n
5.3784 = n
Hence, Alice should take 5.38 ounces of base 10 cakes

In a scatter plot, if all data points were aligned along a 44º angle, the correlation would be_______. a) medium strength. b) low strength. c) high strength. d) 0
In a scatter plot, if all data points were aligned along a 44º angle, the correlation would be 0. The correct answer is D.
In a scatter plot, the correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 indicates no linear relationship.
When all data points are aligned along a 44º angle, it means that the points are distributed randomly and do not follow a clear linear pattern. There is no consistent increase or decrease in one variable as the other variable changes. Therefore, the correlation between the variables is 0, indicating no linear relationship or strength of association.
In other words, the angle of 44º suggests that the variables are unrelated and have no linear dependency on each other.

The sampling technique used in the given scenario is Systematic sampling technique.
Systematic sampling technique
Systematic sampling is a probability sampling technique in which researchers randomly choose individuals of a population at regular intervals. The sampling interval, or fixed periodic interval, is calculated by dividing the population size by the required sample size.
Types of Systematic sampling technique
A systematic sample can be generated in three ways:
Systematic random sampling: The most common type of systematic sampling in which the subject is chosen at a predefined interval.
Linear systematic sampling: Instead of picking the sample interval at random, a skip pattern is constructed by following a linear path.
Circular systematic sampling: It occurs when a sample begins from the same spot where it ends.

Full question:
Heng was trying to factor 10x²+5x. She found that the greatest common factor of these terms was 5x and made an area model: What is the width of Heng's area model?
Answer:
The width of the area model is 2x + 1
Step-by-step explanation:
Given
Expression: 10x² + 5x
Factor: 5x
Required
Width of the Area Model
To solve this, I'll assume the area model is Length * Width
Provided that we're to solve for the width of the model.
This implies that; Length = 5x
Area = Length * Width
And
Area = 10x² + 5x
Equate these two
Length * Width = 10x² + 5x
Factorize express on the right hand side
Length * Width = 5x(2x + 1)
Substitute 5x for Length
5x * Width = 5x(2x + 1)
Divide both sides by 5x
Width = 2x + 1
Hence, the width of the area model is 2x + 1

Use a linear approximation of f(x)=x√ 3 about the value x=64 to estimate √65.3 . Round your answer to four decimal places, if necessary.
Using linear approximation, we estimate that √65.3 ≈ 47.822, rounded to four decimal places.
To use linear approximation, we need to find the equation of the tangent line to the function f(x) at x=64. Then, we can use this tangent line to approximate the value of f(x) near x=64.
First, let's find the equation of the tangent line to f(x) at x=64. The slope of the tangent line is given by the derivative of f(x) at x=64:
f'(x) = √3/2x^(1/2)
f'(64) = √3/2(64)^(1/2) = √3/2 * 8 = 4√3
Equation of tangent line f(x) at x=64:
y - f(64) = f'(64)(x - 64)
y - 64√3 = 4√3(x - 64)
y = 4√3x - 128√3
Now, we can use this tangent line to approximate f(x) near x=64. We want to estimate √65.3, which is close to x=64. Let's substitute x=65.3 into the equation of the tangent line:
y = 4√3(65.3) - 128√3 ≈ 47.822
Therefore, using linear approximation, we estimate that √65.3 ≈ 47.822, rounded to four decimal places.

A father is 4 times as old as his son. In 20 years the father will be twice as old as his son.. Find their present ages
x = the age of his son now, then the age of the father is 4x.
In 20 years,
son's age = x + 20
father's age = 4x + 20
solve the equation for x:
4x + 20 = 2(x + 20)
4x + 20 = 2x + 40
2x = 20
x = 10
So the age of his son now is 10, and the age of the the father now is 40.

Find the product of 32 and 46. Now reverse the digits and find the product of 23 and 64. The products are the same!
Does this happen with any pair of two-digit numbers? Find two other pairs of two-digit numbers that have this property.
Is there a way to tell (without doing the arithmetic) if a given pair of two-digit numbers will have this property?
Let's calculate the products and check if they indeed have the same value:
Product of 32 and 46:
32 * 46 = 1,472
Reverse the digits of 23 and 64:
23 * 64 = 1,472
As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.
To find two other pairs of two-digit numbers that have this property, we can explore a few examples:
Product of 13 and 62:
13 * 62 = 806
Reversed digits: 31 * 26 = 806
Product of 17 and 83:
17 * 83 = 1,411
Reversed digits: 71 * 38 = 1,411
As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.
For example, let's consider the pair 25 and 79:
A = 2, B = 5, C = 7, D = 9
The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.
Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.

A rectangular advertisement is 144 inches wide and 42 inches long. A media company wants to create a billboard advertisement using the scale factor of 4. Part A. What are dimensions of the bill board in feet. Show every step of your work
Using the scale factor of 4, the dimensions of the billboard advertisement are 48 feet x 14 feet.
The problem can be solved using dilation concept.
The scale factor in a dilation is the ratio of the lengths of any two corresponding sides of the original figure and its image after dilation.
The dimensions of the billboard advertisement can be found by multiplying the original dimensions by the scale factor of 4.
Step 1: Multiply the width by the scale factor: 144 inches x 4 = 576 inches
Step 2: Multiply the length by the scale factor: 42 inches x 4 = 168 inches
Step 3: Convert the dimensions from inches to feet: 576 inches ÷ 12 = 48 feet, 168 inches ÷ 12 = 14 feet
Hence, the dimensions of the billboard advertisement in feet are 48 feet wide and 14 feet long.
