Factor out the greatest common factor of Given the expression: 4x^10 − 64x^2
Part A
4x10 – 64x2
= 4x2 * x8 – 4x2 * 16
= 4x2 * (x8 – 16) by distributive property
Part B
x8 is (x4)2 and 16 = 42 so a difference of squares is seen in the parentheses. The pattern a2 – b2 = (a + b)(a – b) can be used.
4x2 * (x8 – 16)
= 4x2 * (x4 + 4) * (x4 – 4)
x4 = (x2)2 and 4 = 22 so there is another difference of squares in the last factor. Use the pattern again.
= 4x2 * (x4 + 4) * (x2 + 2) * (x2 – 2)
Answer:
Below.
Step-by-step explanation:
The GCF = 4x^2
So its 4x^2(x^8 - 16)
This can be further factored
= 4x^2(x^4 - 4)(x^4 + 4)
= 4x^2(x^2 - 2)(x^2 + 2)(x^4 + 4)
In a game, you can get 20 points, 10 points, 2 points. You calculated the expected value of the game; expected value = 5.6. If you play the game many times, how many points can you get on average?
On average, you can expect to get about 4.24 points per game if you play many times.
How to calculate how many points can you get on averageTo find the average number of points you can get by playing the game many times, you can use the expected value as a guide.
The expected value of the game is calculated as follows:
(20 points x probability of getting 20) + (10 points x probability of getting 10) + (2 points x probability of getting 2) = 5.6
Let's use the variables p20, p10, and p2 to represent the probabilities of getting 20 points, 10 points, and 2 points, respectively. Then we can set up the equation:
(20p20) + (10p10) + (2p2) = 5.6
We also know that the sum of the probabilities must equal 1:
p20 + p10 + p2 = 1
Now we have two equations and three variables. We need one more equation to solve for the variables. One way to do this is to assume that the probabilities of getting 20 points, 10 points, and 2 points are proportional to the point values themselves.
In other words, let's assume that:
p20 : p10 : p2 = 20 : 10 : 2
We can then use this proportion to write p20 and p2 in terms of p10:
p20 = 2p10
p2 = 4p10
Now we can substitute these expressions into the two equations we have:
(20p20) + (10p10) + (2p2) = 5.6
p20 + p10 + p2 = 1
Substituting the first equation gives:
(20(2p10)) + (10p10) + (2(4p10)) = 5.6
Simplifying:
80p10 + 10p10 = 5.6
90p10 = 5.6
p10 = 5.6/90
p10 = 0.062
Now we can use the proportions to find p20 and p2:
p20 = 2p10 = 2(0.062) = 0.124
p2 = 4p10 = 4(0.062) = 0.248
Finally, we can calculate the average number of points:
(20 points x 0.124) + (10 points x 0.062) + (2 points x 0.248) = 3.12 + 0.62 + 0.496 = 4.236
So, on average, you can expect to get about 4.24 points per game if you play many times.

HELP I will give brainliest to make the perfect shade of orange cake frosting, Mya needs 8 drops of yellow food coloring for every 12 drops of red food coloring. If she adds 32 drops of yellow food coloring to her frosting, how many drops of red food coloring should she add
Answer: 48 red drops
Step-by-step explanation:
ratio of yellow food drops to red food drops is 8:12
8:12 simplifies to 2:3
2:3 = 2/5:3/5
2x/5 = 32 = # of yellow drops (where x is the total # of drops)
2x/5 = 32
2x = 160
x = 80
Since there are 80 total drops and 32 yellow drops, there must be 48 red drops (80-32=48)

5x+y=9
10x-7y=-18
What is the solution? and show how u got it.
Step-by-step explanation:
To solve the system of equations:
5x + y = 9
10x - 7y = -18
We can use the elimination method by multiplying the first equation by 7 and subtracting it from the second equation:
35x + 7y = 63 (multiplying first equation by 7)
10x - 7y = -18
45x = 45
Dividing both sides by 45, we get:
x = 1
Substituting x = 1 into the first equation:
5(1) + y = 9
Simplifying, we get:
y = 4
Therefore, the solution to the system of equations is x = 1 and y = 4.

384.75 as a fraction
Answer:
1539/4 (improper fraction) or 384 3/4 (simplified fraction)
Step-by-step explanation:
To find the improper fraction, write 384.75 as a fraction:
384.75/1
Then, since you have 2 decimal places after the ., multiply the entire fraction by 100:
38475/100
Next, find the GCF, which is 25, and simplify this fraction to find the final improper fraction:
1539/4
To find the simplified fraction, we already have the whole number, 384, so we have to convert 0.75 to a fraction which is 3/4, because 0.75 is 3/4 of 100:
384 3/4

A report states that of home owners have a vegetable garden. How large a sample is needed to estimate the true proportion of home owners who have vegetable gardens to within 6 percentage points with confidence
To estimate the true proportion of home owners who have vegetable gardens to within 6 percentage points with confidence, a sample size of 384 would be needed.
How big of a sample is required to confidently estimate the true percentage of homeowners having vegetable gardens to within 6 percentage points?This can be calculated using a sample size calculator and the given margin of error and desired confidence level.The size of the sample needed can be calculated using the formula n = (z2 * p * (1-p)) / e2, where n is the size of the sample, z is the z-score associated with the desired confidence level (1.96 for 95% confidence), p is the estimated proportion of home owners having a vegetable garden, and e is the margin of error (6 percentage points).Assuming a conservative estimate of p = 0.50, the sample size needed to estimate the true proportion of home owners having a vegetable garden to within 6 percentage points with 95% confidence is:n = (1.962 * 0.50 * 0.50) / (0.06)2 = 384.9 ≈ 385Therefore, a sample size of 385 home owners is needed to estimate the true proportion of home owners having a vegetable garden to within 6 percentage points with 95% confidence.The equation is: n = (z_alpha/2)^2 * (p*(1-p)) / e^2 Where n is the sample size, z_alpha/2 is the z-score for the desired confidence level (e.g., z = 1.96 for a 95% confidence level), p is the estimated population proportion, and e is the margin of error. For this example, we can assume a 95% confidence level (z = 1.96), a population size of N = 100,000, and a margin of error of 6 percentage points (e = 0.06). Plugging these values into the sample size equation, the required sample size is n = (1.96/2)^2 * (0.5*(1-0.5)) / 0.06^2 This gives us a sample size of n = 384.To learn more about the Theory of Confidence Intervals refer to:

What do you mean by recursion?
Recursion is a programming concept where a function calls itself in order to solve a problem. recursion is a technique for solving problems by breaking them down into smaller subproblems and calling the same function to solve each subproblem until the base case is reached.
It can be a very useful tool when used correctly, but it is important to be aware of the potential pitfalls when implementing it in a program.
To understand recursion, let's consider an example. Let's say you have a stack of boxes and you want to find the box at the bottom of the stack. A simple approach would be to take each box from the top one by one until you reach the bottom.
This approach can be implemented in a program by calling a function that removes the top box and repeats the process until there are no more boxes. This is an example of recursion.

On a chemistry quiz, there are 5 multiple choice questions with 4 choices each. What is the probability that you get a 100% if you strictly guess.
Answer:
0.097%
Step-by-step explanation:
Since this is a series of events probability question, in order to calculate the probability you need to first find the probability of getting each individual answer right and then multiplying those probabilities together. This will give you the probability of getting 100% on the entire test. Since the questions are multiple-choice with 4 choices and only 1 correct choice then the probability of getting one right is 1/4 or 25%. Now that we have that probability we simply need to multiply it 5 times for each individual question.
1/4 * 1/4 * 1/4 * 1/4 * 1/4 = 1/1024 or 0.0009765 or 0.097%

Miguel ran 2 9 10 miles on Monday. On Friday, Miguel ran 5 times as far as he did on Monday. How much farther did Miguel run on Friday than he did on Monday? Miguel ran miles farther on Friday
Answer:
\(11\dfrac{3}{5}$ miles\)
Step-by-step explanation:
Miguel ran \(2\dfrac{9}{10}\) miles on Monday.
On Friday, he ran 5 times as far as he did on Monday.
Miles run on Friday
\(=5 X 2\dfrac{9}{10}\)
\(=5 X \dfrac{29}{10}\\=\dfrac{29}{2}$ miles\)
Difference in Number of Miles Run
\(=\dfrac{29}{2}-\dfrac{29}{10}\\=\dfrac{145-29}{10}\\=\dfrac{116}{10}\\=11\dfrac{3}{5}$ miles\)
Therefore, Miguel ran \(11\dfrac{3}{5}$ miles\) farther on Friday.

the data are normally distributed with a mean of 74.674.6 hours and a standard deviation of 9.19.1 hours. So 10.2% of gadgets were powered by batteries for fewer than 63 hours.
Given that,
Data have a mean of 74.6 hours and a standard deviation of 9.1 hours, and they are regularly distributed.
The standard deviation is defined as ?
The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.
\(p(X\leq 63) = p(Z\leq 63-74.6/9.1)\)
From standard deviation,
\(p(X\leq 63) = p(Z\leq -1.279)= 0.1061\)
a certain percentage of gadgets have battery life of less than 63 hours.
X= 63 hours
Percentage of devices ran on the batteries for fewer than 63 hours = 10.2%
