Answer:
3√512 = 8
Step-by-step explanation:
Step 1: Find the prime factors of 512
512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
Step 2: Pair the factors of 512 in a group of three, such that they form cubes.
512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)
512 = 23 × 23 × 23
Using the law of exponent, we get;
512 = 29 [am.an = (a)m+n]
Or
512 = (23)3 [(am)n = amn]
512 = 83
Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.
3√512 = 3√(83)
So, here the cube root is eliminated by the cube of 8.
Hence, 3√512 = 8

if my y-int is (5,0) and my x-int is (0,80) what is my vertex??
PLEASE HELP ME
The vertex of the Quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).
The vertex of a quadratic function given the y-intercept and x-intercept, we need to determine the axis of symmetry, which is the line that passes through the vertex. The x-coordinate of the vertex will be the midpoint between the x-intercepts, while the y-coordinate will be the same as the y-intercept.
Given that the y-intercept is (5, 0) and the x-intercept is (0, 80), we can determine the x-coordinate of the vertex by finding the midpoint of the x-intercepts. The x-coordinate of the midpoint is simply the average of the x-values:
x-coordinate of vertex = (0 + 0) / 2 = 0 / 2 = 0
Since the y-coordinate of the vertex is the same as the y-intercept, the vertex will have the coordinates (0, 0).
Therefore, the vertex of the quadratic function is (0, 0).
In conclusion, the vertex of the quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

Some tennis player's believe they have a better chance of winning the point if they are the one serving for the point. Suppose that in a particular match, Samson wins 46 of the 62 points when he's serving but only 23 of the 52 points when his opponent is serving. Does this data give convincing evidence that Samson plays better when serving? a) How much better did Samson perform when serving? Calculate the difference in the percentage of points won (the test statistic). Show work. b) State the hypotheses we are interested in testing. c) Suppose that the results of a simulation gave a p-value of 0.24, interpret this value. d) What conclusion would you make based on the p-value from part d? e) If your conclusion from part d was in error, what type of error did you commit? Explain. f) Describe this type of error in context. 9) Describe how to reduce the likelihood of this error occurring. h) If we concluded that Samson's ability to win points when serving is lower than his ability to win points when his opponent is serving, can we conclude that his serving is the cause of the difference?
(A) Total number of points served by Samson and multiply by 100 (B) Null hypothesis(H0) and Alternative hypothesis (Ha) (C) there would be a 24% chance of observing a difference in performance as extreme as the one observed in the data.
(D) Based on the p-value of 0.24, we do not have strong evidence to reject the null hypothesis. (E) it would be a Type II error. (F) Type II error would mean that we concluded there is no difference in Samson's performance when serving and when his opponent is serving, but in reality, there is a difference. (G) To reduce the likelihood of a Type II error occurring, we can increase the sample size (H) No, we cannot conclude that Samson's serving is the cause of the difference in his ability to win points when serving compared to when his opponent is serving
a) The difference in the percentage of points won when serving and when the opponent is serving can be calculated by subtracting the percentage of points won when the opponent is serving from the percentage of points won when serving. To find the percentage of points won when serving, we divide the number of points won when serving by the total number of points served by Samson and multiply by 100. Similarly, to find the percentage of points won when the opponent is serving, we divide the number of points won when the opponent is serving by the total number of points served by the opponent and multiply by 100.
b) The hypotheses we are interested in testing are:
- Null hypothesis (H0): There is no difference in Samson's performance when serving and when his opponent is serving.
- Alternative hypothesis (Ha): Samson performs better when serving compared to when his opponent is serving.
c) A p-value of 0.24 indicates that if the null hypothesis were true, there would be a 24% chance of observing a difference in performance as extreme as the one observed in the data. In other words, the p-value represents the probability of obtaining the observed difference in performance or a more extreme difference, assuming that there is no actual difference in Samson's performance when serving.
d) Based on the p-value of 0.24, we do not have strong evidence to reject the null hypothesis. This means that the data does not provide convincing evidence that Samson plays better when serving compared to when his opponent is serving.
e) If our conclusion from part d was in error, it would be a Type II error. This occurs when we fail to reject the null hypothesis even though it is false. In this case, it would mean that there is a difference in Samson's performance when serving, but we failed to detect it.
f) In the context of this question, a Type II error would mean that we concluded there is no difference in Samson's performance when serving and when his opponent is serving, but in reality, there is a difference. This could potentially lead to underestimating Samson's ability to perform better when serving.
g) To reduce the likelihood of a Type II error occurring, we can increase the sample size. By collecting more data, we can increase the power of our test and improve our ability to detect a difference in performance if it truly exists. Additionally, we can also adjust the significance level of our test (e.g., from 0.05 to 0.01) to make it more likely to detect smaller differences.
h) No, we cannot conclude that Samson's serving is the cause of the difference in his ability to win points when serving compared to when his opponent is serving. The data provided only shows an association between serving and winning points, but it does not establish a causal relationship. Other factors, such as skill, strategy, or the opponent's performance, could also contribute to the difference observed. To establish causality, further investigation and controlled experiments would be needed.

consider an undirected graph that has 100 vertices. for any pair of vertices, only 1 edge can connect them. in other words, you cannot have 2 edges connecting vertex a directly to vertex b. also assume that there are no self-loops, i.e. an edge that goes from vertex a to vertex a. what is the maximum number of edges that can be in this specific graph?
So the maximum number of edges in an undirected graph with 100 vertices is 4950.
In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.
In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:
n * (n-1) / 2
Substituting n = 100, we get:
100 * 99 / 2 = 4950

80 pupils in a sports centre are surveyed. The pupils can only use the swimming pool and the gym. 26 pupils use the swimming pool and the gym. 56 pupils use the swimming pool. 45 pupils use the gym. Find the probability to select a pupil that uses the gym but not the swimming pool.
The probability of selecting a pupil who uses the gym but not the swimming pool is approximately 0.2375 or 23.75%.
To find the probability of selecting a pupil who uses the gym but not the swimming pool, we need to determine the number of pupils who fall into that category and divide it by the total number of pupils surveyed.
Given information:
Total number of pupils surveyed: 80
Number of pupils who use both the swimming pool and the gym: 26
Number of pupils who use the swimming pool: 56
Number of pupils who use the gym: 45
To find the number of pupils who use the gym but not the swimming pool, we can subtract the number of pupils who use both from the total number of pupils who use the gym:
Number of pupils using gym only = Total number of gym users - Number of pupils using both = 45 - 26 = 19.
Therefore, there are 19 pupils who use the gym but not the swimming pool.
To find the probability, we divide the number of pupils who use the gym only by the total number of pupils surveyed:
Probability = Number of pupils using gym only / Total number of pupils surveyed = 19 / 80 = 0.2375.

Please help!!! Angles!
Answer:
m∠JKM = 63°
m∠MKL = 27°
Step-by-step explanation:
Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.
\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)
Solve the equation for x:
\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)
We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,
m∠JKM = 12(5) + 3 = 60 - 3 = 63°
m∠MKL = 6(5) - 3 = 30 - 3 = 27°

If the consumption function for Australia in 2021 is given as = 0.0052 + 0.3 + 20 where: C = total consumption of Australia in the year 2021 Y = total income of Australia in the year 2021 Calculate the marginal propensities to consume (MPC = ) and save when Y = 10. Assume that Australians cannot borrow, therefore total consumption + total savings = total income. Expert Answer
The marginal propensity to consume (MPC) for Australia in 2021, when total income (Y) is 10, is 0.3.
The consumption function for Australia in 2021 is given as C = 0.0052 + 0.3Y + 20, where C represents the total consumption and Y represents the total income. To calculate the MPC, we need to determine how much of an increase in income is consumed rather than saved. In this case, when Y = 10, we substitute the value into the consumption function:
C = 0.0052 + 0.3(10) + 20
C = 0.0052 + 3 + 20
C = 23.0052
Next, we calculate the consumption when income increases by a small amount, let's say ΔY. So, when Y increases to Y + ΔY, the consumption function becomes:
C' = 0.0052 + 0.3(Y + ΔY) + 20
C' = 0.0052 + 0.3Y + 0.3ΔY + 20
To find the MPC, we subtract the initial consumption (C) from the new consumption (C') and divide it by the change in income (ΔY):
MPC = (C' - C) / ΔY
MPC = (0.0052 + 0.3Y + 0.3ΔY + 20 - 23.0052) / ΔY
Simplifying the equation, we can cancel out the terms that don't involve ΔY:
MPC = (0.3ΔY) / ΔY
MPC = 0.3

Boots and Dora are getting aloo parates for their iftaari party. If they paid $75 for 15 aloo parates, what is the unit rate of one aloo parate
Answer:
To find the unit rate of one aloo parate, we need to divide the total cost of 15 aloo parates by the number of aloo parates.
The cost per aloo parate can be calculated by dividing $75 by 15 as follows:
Cost per aloo parate = $75 ÷ 15 = $5

3 is the minimum number of guesses required to guarantee that you know the number.
If we use a binary search approach, we can guess the number in a minimum number of steps.
First, we guess the middle number, which is 8. If the answer is higher, we can eliminate all the numbers from 1 to 8, because they are lower than the answer.
Then we guess the middle number of the remaining numbers, which is 12. If the answer is lower, we can eliminate all the numbers from 12 to 15, because they are higher than the answer.
We have now eliminated half of the remaining numbers, and we are left with 6 and 7. We can guess either of these numbers, and we will know the answer with a total of three guesses.
