Answer:
Jessica has 400 cm^3 of material. She uses 35cm^3 to make a right triangular prism. She wants to make a second prism that is a dilation of the first prism with a scale factor of 2.5.
The volume of the first prism is 35 cm^3. Since the second prism is a dilation of the first prism with a scale factor of 2.5, its volume will be (2.5)^3 = 15.625 times greater than that of the first prism. Therefore, the volume of the second prism will be 35 x 15.625 = 546.875 cm^3.
To make the second prism, Jessica needs an additional material of 546.875 - 35 = 511.875 cm^3.
So Jessica needs an additional material of 511.875 cm^3 to make the second prism.

Find the probability of exactly three
successes in five trials of a binomial
experiment in which the probability of
Success is 90%.
P = [?]%
Round to the nearest tenth of a percent.
The probability of exactly three successes in five trials of a binomial experiment with a 90% probability of success is 0.0729 or about 7.29%.
What is the probability where the P(success) is 90%?To find the probability of exactly three successes in five trials of a binomial experiment with a 90% probability of success, we can use the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
Plugging in the values, we get:
P(X = 3) = (5 choose 3) * (0.9)^3 * (1 - 0.9)^(5 - 3)
= 10 * (0.9)^3 * (0.1)^2
= 0.0729

Select one or more expressions that together represent all solutions to the
equation. Your answer should be in radians.
Assume n is any integer.
-4 cos(5x)+1=1
The solutions for the given equation be written as: x = (2n + 1)π/10, where n is any integer.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It usually contains one or more variables and may involve mathematical operations such as addition, subtraction, multiplication, division, or exponentiation.
According to given information:Starting from the given equation:
-4cos(5x) + 1 = 1
Simplifying the equation, we get:
-4cos(5x) = 0
Dividing both sides by -4, we get:
cos(5x) = 0
Now, we need to find the values of x that satisfy this equation. Recall that the cosine function is equal to 0 at odd multiples of π/2, i.e.,
cos(θ) = 0 for θ = (2n + 1)π/2, where n is an integer.
So, substituting θ = 5x, we get:
cos(5x) = 0 for 5x = (2n + 1)π/2
Dividing both sides by 5, we get:
x = (2n + 1)π/10
So, the solutions for the given equation are:
x = π/10, 3π/10, 5π/10, 7π/10, 9π/10, 11π/10, 13π/10, 15π/10, 17π/10, ...
which can be written as:
x = (2n + 1)π/10, where n is any integer.

Approximately 304,657,600 Americans were there in July 2009 based on the estimated 2008 growth rate of 0.88%.
To find the approximate US population in July 2009, we need to apply the growth rate of 0.88% to the initial population in July 2008.
Convert the growth rate from percentage to decimal:
0.88% = 0.0088
Calculate the number of people added to the population in 2008: 302,000,000 * 0.0088 = 2,657,600
Add this number to the initial population to find the population in July 2009:

(A.) dilation
(B.) horizontal stretch
(C.) reflection
(D.) rotation
(E.) translation
(C.) reflection and (D.) rotation produce congruent images.
What three transformations are congruent?
We can generate congruent shapes by combining the three types of transformations: rotations, reflections, and translations. Actually, using a combination of one or more of these three transformations, any pairs of congruent shapes can be matched to one another.
(A) Dilation, (B) horizontal stretch, and (E) translation do not produce congruent images because they change the size, shape, and/or orientation of the original object.
(C) Reflection produces congruent images because the resulting image is a mirror image of the original object, and therefore has the same size and shape.
(D) Rotation produces congruent images because the resulting image is the same shape and size as the original object, just rotated to a different orientation.

A line of best fit was drawn for 16 data points. What is the maximum number of these data points that mav not actually be on the line?
O A. 15
O B. 16
O C. 14
O D. 13
Answer:
The maximum number of data points that may not actually be on the line of best fit for 16 data points is 15 (Option A). This is because a line of best fit is an approximation of the relationship between the variables being studied, and it is unlikely that all data points will fall exactly on the line.
Step-by-step explanation:
To determine the line of best fit, a regression analysis can be performed. This involves finding the equation of the line that best represents the relationship between the variables. The line of best fit minimizes the distance between each data point and the line.
However, even with a perfect line of best fit, there may still be some data points that do not fall exactly on the line. This is due to natural variability in the data and measurement error.
Therefore, it is possible for all 16 data points to fall on the line of best fit, but it is more likely that some points will deviate slightly from the line. The maximum number of data points that may not actually be on the line is 15.

fP=\ (x, y) : y = 3x-1, x ≤ 4, xe N}, find P * 1 State the elements of the following relations: (b) y = 4x (d) x + y >= 20 y = x (a) (c) x + y
Answer:
Step-by-step explanation:
To find P * 1, we need to find all pairs of elements in P that have a difference of 1. Let's start by listing the elements of P:
P = {(1, 2), (2, 5), (3, 8), (4, 11)}
Now, we can find all pairs of elements in P that have a difference of 1:
(1, 2), (2, 5) -> (1, 5)
(2, 5), (3, 8) -> (1, 3)
(3, 8), (4, 11) -> (1, 3)
Therefore, P * 1 = {(1, 5), (1, 3), (1, 3)} = {(1, 5), (1, 3)} (since the last pair is a duplicate).
(b) The given relation is: y = 4x
The elements of this relation are all pairs (x, y) such that y = 4x. For example, (1, 4), (2, 8), (3, 12), etc.
(c) The given relation is: x + y ≥ 20
The elements of this relation are all pairs (x, y) such that x + y is greater than or equal to 20. For example, (1, 19), (2, 18), (3, 17), etc.
(d) The given relation is: y = x
The elements of this relation are all pairs (x, y) such that y = x. For example, (1, 1), (2, 2), (3, 3), etc.
order the measurements from greatest to least 45 inches, 6 yards, and 2 and1/4 feet
Answer:
2.25 feet, 45 inches, and 6 yards
Step-by-step explanation:
first, convert all to the same unit of measurement
I will use inches
45 inches = 45 inches
6 yards, 1 yard = 3 feet so 6 yards are equal to 18 feet and 1 foot is equal to 12 inches so 12*18 is 216 inches so 6 yards = 216 inches
Next 1 foot equals 12 inches so 2.25 * 12 = 27 so 2.25 feet = 27 inches.
Now let's look at the complete conversion
45 inches
6 yards = 216 inches
2.25 feet = 27 inches
looking at the inches we can see that 27 is the least then 45 then 216 therefore
2.25 feet < 45 inches < 6 yards so the order is
2.25 feet, 45 inches, and 6 yards

a bin of 10 light bulbs contains 4 that are defective, if 3 bulbs are chosen with replacement from the bin, what is the chane that exactly 2 fo bulbs in the sample are defective
The probability of exactly 2 defective bulbs in a sample of 3 bulbs chosen with replacement from the bin is 0.288 or approximately 28.8%.
To solve this problem, we can use the binomial probability distribution formula:
P(X=k) = (n choose k) * p^k * (1-p)^(n-k)
Where P(X=k) is the probability of getting exactly k successes, n is the total number of trials, p is the probability of success in each trial, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.
In this case, n = 3 (because we are choosing 3 bulbs), p = 4/10 = 0.4 (because the probability of choosing a defective bulb is 4 out of 10), and we want to find P(X=2) (the probability of getting exactly 2 defective bulbs).
Substituting these values into the formula gives:\
P(X=2) = (3 choose 2) * 0.4^2 * (1-0.4)^(3-2)
= 3 * 0.16 * 0.6
= 0.288

A percent is a way of a expressing a part out of 100. Remember learning about ratios and how they compare quantities? A part-to-whole ratio is a ratio that compares a part of a whole to another part of a whole. A percent is a part-to-whole ratio where the whole is 100. 40%, or 40 out of 100, is a ratio that compares 40, the part, to 100, the whole.
Which of these could you express as a percent?

a newsletter publisher believes that more than 51% of their readers own a personal computer. is there sufficient evidence at the 0.05 level to substantiate the publisher's claim? state the null and alternative hypotheses for the above scenario.
Answer: The null hypothesis for this scenario is that the proportion of readers who own a personal computer is 0.51 or less:
H0: p <= 0.51
The alternative hypothesis is that the proportion of readers who own a personal computer is greater than 0.51:
Ha: p > 0.51
To test this hypothesis, we would need to collect a random sample of readers and determine the proportion of readers who own a personal computer in the sample. We could then use a one-sample proportion test to determine whether the proportion in the sample is significantly different from the null hypothesis value of 0.51. If the p-value is less than 0.05, we would reject the null hypothesis and conclude that there is sufficient evidence to substantiate the publisher's claim that more than 51% of their readers own a personal computer. If the p-value is greater than or equal to 0.05, we would fail to reject the null hypothesis and conclude that there is not sufficient evidence to substantiate the publisher's claim.

Find the discriminate y=-x^2-6x19
Answer: 112
Step-by-step explanation:
To find the discriminant of a quadratic equation in the form of y = ax^2 + bx + c, where a, b, and c are constants, we can use the formula:
Discriminant = b^2 - 4ac
In this case, the quadratic equation is y = -x^2 - 6x + 19. So, we can identify the coefficients:
a = -1
b = -6
c = 19
Then, we can substitute these values into the formula for the discriminant:
Discriminant = b^2 - 4ac
= (-6)^2 - 4(-1)(19)
= 36 + 76
= 112
Therefore, the discriminant of the quadratic equation y = -x^2 - 6x + 19 is 112.

Answer:
Step-by-step explanation:
To find out how many weeks it will take to fill the high school's order, we need to solve the equation for the number of weeks (x). We can start by plugging in the given value of 104 for y since y represents the number of cabinets, and then solving for x:
y = 8x + 40
104 = 8x + 40

Calculate the size of angle edc
Answer:
64 degrees
Step-by-step explanation:
Corresponding angles are equal so angle BAF = 133 degrees. Supplementary angles add to 180 degrees so angle AFC = 47 degrees.
Angles on a straight line add to 180 degrees so angle CFE = 180 - 47 = 133 degrees.
Angles in a quadrilateral add to 360 degrees so angle EDC = 360 - (133 + 101 + 62) = 64 degrees.
Therefore angle EDC = 64 degrees
What is ¨the amount of space in a gift box for earrings¨ unit of measurement
A - Square meters
B - Yards
C - Cubic inches
D - Cubic feet
E - Square centimeters
The amount of space in a gift box for earrings would typically be measured in cubic inches (C).
how to solve the question?
Cubic inches is a unit of volume that is commonly used to measure the capacity of small, enclosed spaces like boxes, containers, and packaging. It is defined as the volume of a cube that measures one inch on each side.
For a gift box designed to hold earrings, the volume of the box would need to be sufficient to accommodate the size of the earrings and any additional padding or decorative elements. Since earrings are small, the gift box would likely have a small volume, measured in cubic inches.
Other units of measurement, like square meters or yards, are used to measure the area of two-dimensional surfaces like floors, walls, or yards. Square centimeters are also a unit of area measurement, but they are much smaller than square meters or yards, and may be used to measure the surface area of small objects.
Cubic feet is a larger unit of volume measurement that may be used for larger boxes or containers, like shipping crates or storage bins. However, for a gift box designed specifically for earrings, cubic inches is likely the most appropriate unit of measurement.
