48 cubes takes to fill the given prism. This can be solved using the concept of multiplication.
What is prism?Identical at both ends, a prism is a three-dimensional solid object. It is a result of the elements of flat sides, similar bases, and equal cross-sections. Parallelograms or rectangles without bases make up the prism's faces. A three-dimensional structure with flat sides is known as a prism. Two identically shaped and sized ends are present (and look like a 2D shape). If you cut through it, you would see the identical 2D form on both ends since it has the same cross-section all the way down the shape.
Given that,
the length of the prism is \(\frac{8}{3}\) cm, and it is made up of eight \(\frac{1}{3}\) cm cubes
The width is \(\frac{3}{3}\) cm, so it is made up 3 rows of \(\frac{1}{3}\) cm cubes
That means the bottom layer of cubes is made up of 3 rows of 8 cubes = 3 × 8 = 24
∴ the bottom layer is made of 24 cubes
The height is \(\frac{2}{3}\) cm, so it is made up of 2 layers of \(\frac{1}{3}\) cm cubes.
So, there are 2 layers of 24 cubes
∴ 48 cubes takes to fill the given prism.

for k> 1, chebyshev’s theorem is useful in estimating the proportion of observations that fall within __________.
For k > 1, Chebyshev's theorem is useful in estimating the proportion of observations that fall within k standard deviations of the mean.
Specifically, Chebyshev's theorem states that for any distribution (regardless of shape), at least (1 - 1/k^2) of the observations fall within k standard deviations of the mean.
For example, if we use k = 2, then at least 75% of the observations will fall within 2 standard deviations of the mean (because 1 - 1/2^2 = 0.75).
If we use k = 3, then at least 88.9% of the observations will fall within 3 standard deviations of the mean (because 1 - 1/3^2 = 0.8889).
However, it's important to note that Chebyshev's theorem gives only a lower bound on the proportion of observations that fall within k standard deviations of the mean, and the actual proportion can be much higher in many cases, especially for distributions that are close to normal.

Answer and Step-by-step explanation:
We are given:
\(\frac{2y-1}{-3} = 5\)
First, we multiply both sides by -3.
2y - 1 = 15
Now we add 1 to both sides.
2y = 16
Finally, we divide by 2 to each side.
y = 8
We are given:
2x + 30 = -4(5x -2)
First we distribute the -4 to 5x and -2.
2x + 30 = -20x + 8
Now we subtract 8 from both sides.
2x + 22 = -20x

Norma makes bags.
She makes 17 bags an hour.
Norma works for 6 hours each day, 5 days a week.
Each bag is checked.
If the bag is perfect, it is put in a box.
When there are 12 bags in a box it is full.
One week 90% of the bags Norma made were perfect.
Work out the number of boxes completely filled with bags made by Norma.
Answer:
38
Step-by-step explanation:
She makes 17 bags an hour. Multiply 17 bags by each hour. Additionally, multiply that by 5 for each day worked. The total number is 510.
Out of 510 bags made in that week, only 90% are perfect. 90% of 510 is 459.
If there are 459 bags, and each box can hold 12, how many boxes will be full? Keep adding bags into boxes until you reach 0 bags. The equation you'll want is 459/12.
38 boxes will be full, with 3 remainder bags.

In BINGO, a $5\times5$ card is filled by marking the middle square as WILD and placing 24 other numbers in the remaining 24 squares. Specifically a card is made by placing 5 numbers from the set $1-15$ in the first column, 5 numbers from $16-30$ in the second column, 4 numbers $31-45$ in the third column (skipping the WILD square in the middle), 5 numbers from $46-60$ in the fourth column and 5 numbers from $61-75$ in the last column. One possible BINGO card is: To play BINGO, someone names numbers, chosen at random, and players mark those numbers on their cards. A player wins when he marks 5 in a row, horizontally, vertically, or diagonally. How many distinct possibilities are there for the values in the diagonal going from top left to the bottom right of a BINGO card, in order?

1 20 31 50 71
There are a total of $15^5 = 759,375$ distinct possibilities for the values in the diagonal going from top left to the bottom right of a BINGO card, in order.
To find the number of distinct possibilities for the values in the diagonal going from top left to the bottom right of a BINGO card, we need to consider the range of numbers that can be placed in the diagonal.
In the given BINGO card, the diagonal starts with the number 5 in the top left corner and ends with the number 71 in the bottom right corner. We can see that the numbers in the diagonal follow a pattern:
5, 17, 32, 49, 71
We can analyze this pattern to find the number of distinct possibilities.
- The first number, 5, can be any number from the set $1-15$.
- The second number, 17, can be any number from the set $16-30$.
- The third number, 32, can be any number from the set $31-45$.
- The fourth number, 49, can be any number from the set $46-60$.
- The fifth number, 71, can be any number from the set $61-75$.
To find the number of distinct possibilities, we multiply the number of choices for each position:
15 choices for the first number × 15 choices for the second number × 15 choices for the third number × 15 choices for the fourth number × 15 choices for the fifth number

(a) why does the mean accurately summarize a normal distribution? (b) why does the mean inaccurately summarize a skewed distribution?
The mean accurately summarize a normal distribution because it is the center point. While the mean inaccurately summarize a skewed distribution because the mean is meant to balance the distribution with a tail, it is pulled to a tail and therefore the mean would not be in the center.
The mean is the mathematical average and it is probably the measure of central tendency that is most familiar. One can calculate the mean by adding all the values and dividing it with the total number of observations in a set of data. The normal distribution of mean is observed when the distribution of data near the mean are more frequent in occurrence than data far from the mean, it is also referred as Gaussian distribution. Skewed distribution is not symmetrical nor equal, it is deviated in one or the other side of the graph.

Step-by-step explanation:
assume that each of the n trials is independent and that p is the probability of success on a given trial. use the binomial probability formula to find p(x). n=5, x=3, p=0.3
The probability of getting exactly 3 successes (p(x)) in 5 independent trials, each with a probability of success (p) of 0.3, is approximately 0.1323, or 13.23%.
To find the probability of getting exactly x successes (p(x)) in n independent trials, each with a probability of success (p) using the binomial probability formula, we can follow these steps:
Step 1: Identify the values:
n = 5 (number of trials)
x = 3 (number of successes)
p = 0.3 (probability of success on a given trial)
Step 2: Apply the binomial probability formula:
The binomial probability formula is given by:
p(x) = (nCx) * (p^x) * ((1 - p)^(n - x))
Step 3: Calculate the values:
nCx represents the number of ways to choose x successes from n trials and can be calculated using the combination formula:
nCx = n! / (x! * (n - x)!)
In our case, n = 5 and x = 3, so:
nC3 = 5! / (3! * (5 - 3)!)
= 5! / (3! * 2!)
= (5 * 4 * 3!) / (3! * 2 * 1)
= (5 * 4) / (2 * 1)
= 10
Now we can substitute the values into the binomial probability formula:
p(3) = (10) * (0.3^3) * ((1 - 0.3)^(5 - 3))
= 10 * (0.3^3) * (0.7^2)
= 10 * (0.027) * (0.49)
= 0.1323
Step 4: Final Answer:
Therefore, the probability of getting exactly 3 successes (p(x)) in 5 independent trials, each with a probability of success of 0.3, is 0.1323, or approximately 13.23%.

Find the intercept of the parabola
y=x^2-3x+7/4
The x-intercepts of the parabola are approximately (0.8, 0) and (2.2, 0).
A parabola is a symmetrical curve with a U- or smile-shaped shape. It is a particular kind of conic section, a shape created by cutting a cone with a plane.
The set of all points in a plane that are equally distant from a fixed point (referred to as the focus) and a fixed line is known as a parabola (called the directrix).
To find the y-intercept of a parabola, we can set x=0 and solve for y.
y = x² - 3x + 7/4
When x=0:
y = (0)² - 3(0) + 7/4 = 7/4
So the y-intercept of the parabola is (0, 7/4).
To find the x-intercepts, we can set y=0 and solve for x:
0 = x² - 3x + 7/4
We can solve this quadratic equation using the quadratic formula:
\(x = \dfrac{[ -(-3) \pm\sqrt{( (-3^2- 4(1)(\dfrac{7}{4})} ) ]} { (2x_1)}\)
\(x = \dfrac{[ 3 \pm \sqrt{( 9 - 7 )} ]} {2}\)
\(x =\dfrac{ [ 3 \pm \sqrt{(2)} ]} { 2}\)
So the x-intercepts of the parabola are approximately (0.8, 0) and (2.2, 0).

Step-by-step explanation:
we first need to find out how many words typed per minute so we divide 75 by 3 (3 divided by 3 is 1 and what we do to one side must be done to the other)
75 ÷ 3 = 25
25 word per 1 minute
now we need to multiply the minute by 25 to get the number of words typed
25(words) x 1(minute) = 25 words in 1 minute(so A is correct)
25(words) x 2(minute) = 50 words in 2 minutes(so B is correct)
25(words) x 4(minute) = 100 words in 4 minutes (so C is correct)
25(words) x 5(minute) = 125 words in 5 minutes(so D is incorrect)

By using Fundamental Theorem of Calculus, we find the derivative of the function g(x) = In { sqrt( t + t^3)dt } limit from x to 0 is ln(sqrt(x + x^3)). The derivative of the function g(x) = { In (1+t^2) dt} where limit are from x to 1 is ln(1 + x^2).
The Fundamental Theorem of Calculus, which states that if a function is defined as the definite integral of another function, then its derivative is equal to the integrand evaluated at the upper limit of integration.
So, applying this theorem, we have:
g'(x) = d/dx [∫x_0 ln(sqrt(t + t^3)) dt]
= ln(sqrt(x + x^3)) * d/dx (x) - ln(sqrt(0 + 0^3)) * d/dx (0)
= ln(sqrt(x + x^3))
Therefore, g'(x) = ln(sqrt(x + x^3)).
Using the Fundamental Theorem of Calculus, we have:
g'(x) = d/dx [∫1_x ln(1 + t^2) dt]
= ln(1 + x^2) * d/dx (x) - ln(1 + 1^2) * d/dx (1)
= ln(1 + x^2)
Therefore, g'(x) = ln(1 + x^2).

A rectangular solid with a square base has a volume of 4096 cubic inches - determine the dimensions that yield the minimum surface area
Answer:
side of base, a = 10.1 inches, height, h = 40.1 inches
Step-by-step explanation:
Volume of rectangular solid, V = 4096 cubic inches
Let the side of base is a and the height is h.
\(V = a^2h\\\\4096 = a^2 h ..... (1)\)
surface area of the solid
\(S = 2a^2 + 4 ah \\\\S = 2a^2 + 4 \times a \times \frac{4096}{a^2} from (1)\\\S = 2a^2 + \frac{4096}{a}\\\\\frac{dS}{da}= 4 a - \frac{4096}{a^2}\\\\4 a - \frac{4096}{a^2} = 0 \\\\a^3 = 1024\\\\a =10.1 inches\)
So, h = 40.2 inches

It could be slightly lower or higher, but we can be confident that it falls somewhere between 0.32 minutes and 1.47 minutes.
The most accurate interpretation of the given confidence interval is as follows:
We are 95% confident that the true difference in mean wait time between Facility A and Facility B falls within the range of 0.32 minutes to 1.47 minutes.
This means that if we were to repeat the study multiple times and calculate a new confidence interval each time, we would expect that approximately 95% of those intervals would contain the true difference in mean wait time between the two facilities.
Furthermore, based on the observed data and the calculated confidence interval, we can conclude that the difference in mean wait time between Facility A and Facility B is likely to be positive, with Facility B having a higher mean wait time than Facility A. However, we cannot say with certainty that the true difference is exactly within this specific range; it could be slightly lower or higher, but we can be confident that it falls somewhere between 0.32 minutes and 1.47 minutes.
