Two dice are rolled. Let X and Y denote, respectively, the largest and the smallest values obtained a. Compute the conditional probability mass function of Y-i given X-1, for i-1,2, ..., 6 b. Are X and Y independent? Why or why not?
Answers
The conditional PMF of Y=i given X=1 is 1 if i=1 and 0 otherwise and X and Y are not independent because the value of X affects the possible range of values for Y.
a. To compute the conditional probability mass function (PMF) of Y=i given X=1, we need to find the probability of Y=i when X=1. Since X=1, the only possible outcome is (1,1), and Y can only be 1. Hence, the conditional PMF of Y=i given X=1 is:
P(Y=i | X=1) = 1, if i=1; 0, otherwise.
b. X and Y are not independent. If they were independent, the outcome of one die roll would not provide any information about the other die roll. However, given that X is the largest value and Y is the smallest value, we can see that X directly affects the possible range of values for Y. If X is 6, then Y cannot be greater than 6. Therefore, the values of X and Y are dependent on each other, and they are not independent.
Therefore, The conditional PMF of Y=i given X=1 is 1 if i=1 and 0 otherwise and X and Y are not independent because the value of X affects the possible range of values for Y.

11. angle MLN and angle JLK are complementary, m angle MLN=7x-1 and m angle JLK=4x+3 . a. Solve for x b. Find m angle MLN and m angle JKL .
Answers
a. Solve for x
Since angle MLN and angle JKL are complementary, the value of x = 8
Since angle MLN and angle JKL are complementary, their sum equal 90°.
Since angle MLN = 7x - 1 and angle JKL = 4x + 3, we have that
7x - 1 + 4x + 3 = 90
Collecting like terms, we have
7x + 4x - 1 + 3 = 90
Simplifying, we have
11x + 2 = 90
Subtracting 2 from both sides, we have
11x = 90 - 2
11x = 88
Dividing through by 11, we have
x = 88/11
x = 8
So, Since angle MLN and angle JKL are complementary, the value of x = 8
b. Find m angle MLN and m angle JKL .
Since angle MLN=7x-1 and angle JLK=4x+3 thus, angle MLN = 55° and angle JKL = 35°
Since angle MLN = 7x - 1 and x = 8, we have
angle MLN = 7x - 1
angle MLN = 7(8) - 1
angle MLN = 56 - 1
angle MLN = 55°
Since angle JKL = 4x + 3 and x = 8, we have
angle JKL = 4x + 3
angle JKL = 4(8) + 3
angle JKL = 32 + 3
angle JKL = 35°
So, Since angle MLN=7x-1 and angle JLK=4x+3 thus, angle MLN = 55° and angle JKL = 35°

(2 points) • For parts c-e, calculations are not necessary. c. Suppose the standard deviation of the tests had been 42.8 instead of 21.4.

If the sample size was increased to 75 subjects, will the interval be wider or narrower? (1 point)
Answers
a) Entering this into a calculator gives us:CI = (63.876, 88.524) b) test for the population is between 63.876 and 88.524 c) If the standard deviation of the test scores had been 42.8 instead of 21.4, the width of the confidence interval would increase. d) . If the confidence level were reduced to 90%, the interval would be narrower. e) If the sample size was increased to 75 subjects, the interval would be narrower.
a. To find a 95% confidence interval for the mean score on the test, we can use the formula:
To find the confidence interval, we need to estimate the population standard deviation with the sample standard deviation. So:
CI = 76.2 ± 1.96 * (21.4/√27)
Entering this into a calculator gives us:
CI = (63.876, 88.524)
b. The confidence interval we found tells us that we are 95% confident that the true mean score on the test for the population is between 63.876 and 88.524. In other words, if we were to take many random samples of 27 people and compute a 95% confidence interval for each one, then about 95% of those intervals would contain the true population mean.
c. If the standard deviation of the test scores had been 42.8 instead of 21.4, the width of the confidence interval would increase. This is because a larger standard deviation means that the data are more spread out, which makes it more difficult to estimate the population mean accurately.
d. If the confidence level were reduced to 90%, the interval would be narrower. This is because a higher confidence level requires a larger z-score, which widens the interval. Conversely, a lower confidence level requires a smaller z-score, which narrows the interval.
e. If the sample size was increased to 75 subjects, the interval would be narrower. This is because a larger sample size decreases the standard error (σ/√n), which makes it easier to estimate the population mean accurately and results in a narrower confidence interval.

if the major arc is 218 degrees, what is the measurement of the minor arc
Answers
To answer this question, we must be familiar with the relationship between a major and minor arc in a circle.
In a circle, if the measure of the major arc is known, the measurement of the minor arc can be found by subtracting the major arc from 360°.For example, given a major arc measuring 218°, the minor arc would be 360° - 218°.
Therefore, the measurement of the minor arc would be 142°.Hence, the correct option is A) 142 degrees.

The greatest possible value of abc, given that a³b³ = c³ and a, b, and c are integers between -10 and 10 inclusive, is 1.
If a, b, and c are integers between -10 and 10 inclusive such that a³b³ = c³, then what is the maximum possible value of abc?We will start with listing the cubes of numbers between -10 and 10. Below is the table of cubes of numbers between -10 and 10 inclusive.
{-1000, -729, -512, -343, -216, -125, -64, -27, -8, -1, 0, 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000}In the table above, the only numbers that occur thrice are 1, -1, and 0.
All the other numbers are either negative or positive and occur once.So, this means that a, b, and c must be either 1, -1, or 0. This is because if a, b, and c are any other numbers, the left side of the equation, a³b³ = c³, is going to be a cube of some number between -10 and 10 inclusive which is not in the table above.
Hence, this would mean that a³b³ ≠ c³. Therefore, a, b, and c must be either 1, -1, or 0.Now, we can determine the largest possible product of abc: abc = (1)(1)(1) = 1 or (1)(1)(0) = 0 or (-1)(-1)(1) = -1. In conclusion, the greatest possible value of abc is 1.
The greatest possible value of abc, given that a³b³ = c³ and a, b, and c are integers between -10 and 10 inclusive, is 1.

The fraction that would make the equation true is 2/3.
We are given the equation 4 × ? ? = 6 2 3 2 3 3 3 5 3. To solve the equation 4 × ? ? = 6, we need to find the value of the missing fraction. We can rewrite the equation as 4 × x = 6, where x represents the missing fraction.
To isolate x, we divide both sides of the equation by 4, resulting in x = 6/4. Simplifying the fraction gives x = 3/2. Therefore, the missing fraction that makes the equation true is 3/2, which can also be written as 2/3 in simplified form.
