a. The probability that the 3 counters each have a different color is: 1/2 * 7/12 * 2/5 = 7/100b. Work out how many blue counters there are in the jar: There are a total of 3 colors. Therefore, it is given that: Blue + Red + Green = 15Let the number of blue counters be B. Therefore, the number of red counters = R and the number of green counters = G. Thus, B + R + G = 15
(i)Now, the probability that the 3 counters each have a different color is given as follows: P(BRG) = P(B) * P(R) * P(G/B and R)There are 3 ways in which we can have a jar with different colored balls: Blue, Red and Green; Red, Blue and Green; Green, Red and Blue. In each of these cases, there will be the same probability that each one of these cases would occur. Hence we need to multiply the probability of one of them by 3.Below is the probability distribution of selecting 1 counter from the bag at random: Blue = 3/12 = 1/4Red = 4/12 = 1/3Green = 5/12
Let us consider the case of selecting 1 counter from the bag at random with all colors having a different number of counters. There is a 1/4 chance of selecting a blue counter. Once a blue counter has been chosen, there will be 2 blue counters left in the jar. Hence, there will be 11 counters left in the jar of which 4 will be red. There is a 4/11 chance of selecting a red counter. Once a red counter has been chosen, there will be 3 red counters left in the jar. Hence, there will be 10 counters left in the jar of which 5 will be green.
There is a 5/10 chance of selecting a green counter. The probability that the 3 counters each have a different color is: P(BRG) = 1/4 * 4/11 * 1/2 = 1/22The probability that any 2 colors will be present will be the sum of the probability that BRG and that the probability that RGB will be drawn. P(BRG, BRG) = 1/22P(BRG, RGB) = 1/22P(RBG, RGB) = 1/22The probability that any 2 of the three colors will be present = 1/22 + 1/22 + 1/22 = 3/22
The probability that all 3 counters will have the same color is: P(BBB) = 3/12 * 2/11 * 1/10 = 1/220P(GGG) = 5/12 * 4/11 * 3/10 = 6/220P(RRR) = 4/12 * 3/11 * 2/10 = 1/55The total probability of getting the same color = 1/220 + 6/220 + 1/55 = 1/20The probability that the 3 counters each have a different color is: 1/22The probability that any 2 of the three colors will be present = 3/22 The probability that the 3 counters each have the same color is: 1/20 Given that there are 15 counters in the jar, then: B + R + G = 15
(i)Also, it is given that there are 12 counters in the bag. Therefore: B + R + G = 12We can subtract equation (i) from equation (ii) to obtain:0B + 0R + 0G = -3Thus, the equation is inconsistent and there are no solutions. Therefore, there are no blue counters in the jar.

The Σx = 68, y = 79, xy = 1200 x² = 600 and N = 12 determine the equation of the least square line. Leave answer in 2 decimal places.
To determine the equation of the least squares line, we need to find the slope (m) and the y-intercept (b) using the given data. The formula for the least squares line is:
y = mx + b
where:
m is the slope of the line
b is the y-intercept of the line
We can use the following formulas to calculate the slope and y-intercept:
m = (NΣxy - ΣxΣy) / (NΣx² - (Σx)²)
b = (Σy - mΣx) / N
Given the values:
Σx = 68
Σy = 79
Σxy = 1200
Σx² = 600
N = 12
Let's substitute these values into the formulas:
m = (12 * 1200 - 68 * 79) / (12 * 600 - (68)²)
b = (79 - m * 68) / 12
Calculating the values:
m = (14400 - 5372) / (7200 - 4624)
m = 9028 / 2576
m ≈ 3.5039
b = (79 - 3.5039 * 68) / 12
b = (79 - 238.2752) / 12
b ≈ -13.2738

To determine the equation of the least squares line, we need to find the slope (b) and y-intercept (a) using the following formulas:
b = (NΣxy - ΣxΣy) / (NΣx² - (Σx)²)
a = (Σy - bΣx) / N
Given the following values:
Σx = 68
Σy = 79

N = 12
Let's calculate the slope (b) first:
b = (12 × 1200 - 68×79) / (12×600 - 68²)
b ≈ 1.25
Now we can calculate the y-intercept (a):
a = (79 - 1.25×68) / 12
a = 10.75

A survey of 150 college students was done to find out what elective course they were taking Lot A the set of those taking ort, B the set of those taking basketweaving, and C - the set of those taking canoeing. The study revealed the following information A-45 IAN B = 12 181 55 ANC-15 C-40 BC-2 Anno 2
Based on the given information, we can calculate the number of students who were not taking any of the elective courses.
Let's break down the information provided:
A: The set of students taking Art elective = 45
B: The set of students taking Basket weaving elective = 12
C: The set of students taking Canoeing elective = 40
A ∩ B: The set of students taking both Art and Basket weaving electives = 2
A ∩ C: The set of students taking both Art and Canoeing electives = 15
B ∩ C: The set of students taking both Basket weaving and Canoeing electives = 0 (not specified)
A ∩ B ∩ C: The set of students taking all three electives = 2
To find the number of students who were not taking any of these electives, we need to subtract the total number of students taking at least one elective from the total number of students surveyed.
Total students surveyed = 150
Students taking at least one elective = A ∪ B ∪ C
Students taking at least one elective = A + B + C - (A ∩ B) - (A ∩ C) - (B ∩ C) + (A ∩ B ∩ C)
Students taking at least one elective = 45 + 12 + 40 - 2 - 15 - 0 + 2
Students taking at least one elective = 82
Students not taking any of these electives = Total students surveyed - Students taking at least one elective
Students not taking any of these electives = 150 - 82
Students not taking any of these electives = 68
Therefore, there were 68 students who were not taking any of the elective courses using set theory.

Let R be the binary relation defined on a set of all integers Z as follows: for all integers m and n, mRn m’ – n’ is divisible by 6. a) Is R an equivalence relation? Check the conditions. b) What is the equivalence class of -17?
Previous question
The required solutions are:
a) Yes, the relation R is an equivalence relation.
b)The equivalence class of -17 is {-17, -23, -29, -35, ...}.
a) In order to determine whether R is an equivalence relation or not, we need to check if it satisfies the following three conditions:
Reflexibility: For all integers m, mRm should hold. In the given case, if we take m=n, we have m-n=n-m=0, which is divisible by 6. So, we can see that the reflexibility is satisfied.Transitivity: For all integers m, n, and p, if mRn and nRp hold, then mRp should also hold. Assume mRn and nRp, which means m-n, and n-p are both divisible by 6. To check transitivity, we need to check if m - p is divisible by 6. By adding the two previous conditions, we have (m-n) + (n-p) = m-p, which is also divisible by 6. Therefore, transitivity is satisfied.Symmetry: For all integers m and n, if mRn holds, then nRm should also hold. If mRn, it means m-n is divisible by 6. In order to check the symmetry, we need to check if n - m is divisible by 6. We can use the fact that a-b = -(b-a), we can rewrite n - m as -(m - n), which is divisible by 6. So, we can say that symmetry is satisfied.We can see that the relation 'R' satisfies all the conditions ( reflexibility, symmetry, and transitivity), so R is an equivalence relation.
b) In order to find the equivalence class of -17, we need to find all integers that are related to -17 under the relation R.
We can rewrite the relation as mRn if and only if m' - n' = 6k for some integer k.
In this case, -17Rn if and only if (-17)' - n' = -17 - n = 6k for some integer k.
To find all integers n that satisfy this equation, we can rearrange it as n = -17 - 6k.
By putting in different values of k, we can find all the integers n that are in the equivalence class of -17.
For example, when k = 0, n = -17 - 6(0) = -17. So, -17 is in the equivalence class of -17.
We can also see that when k = 1, n = -17 - 6(1) = -23. So, -23 is also in the equivalence class of -17.
The equivalence class of -17 consists of all integers that can be obtained by subtracting multiples of 6 from -17. So, the equivalence class of -17 is {-17, -23, -29, -35, ...}.

simplify your answer and write it as a proper fraction, mixed number, or whole numer.
___ classrooms per minute
Given,A school janitor has mopped 1/3 of a classroom in 5 minutes.We have to find the rate at which he is mopping.Using the concept of unitary method,Rate of mopping 1 classroom in 5 × 3 = 15 minutes= 1/15 of a classroom in 1 minute.Rate of mopping 1/3 classroom in 5 minutes = (1/3) ÷ 5= 1/15 classroom per minuteHence, the required rate at which he is mopping is 1/15 classroom per minute.
Answer: 1/15.
To determine the rate at which the janitor is mopping, we can calculate the fraction of the classroom mopped per minute.
Given that the janitor mopped 1/3 of the classroom in 5 minutes, we can express this as:
(1/3) classroom / 5 minutes
To simplify this fraction, we divide the numerator and denominator by the greatest common divisor, which is 1:
(1/3) classroom / (5/1) minutes = (1/3) classroom × (1/5) minutes
Multiplying the numerators and the denominators gives us:
1 classroom × 1 minute / 3 × 5
Simplifying further:
1 classroom × 1 minute / 15
Therefore, the rate at which the janitor is mopping is 1/15 classrooms per minute.

The following data are cost (in cents) per ounce for nine different brands of sliced Swiss cheese (www .consumerreports.org):
29 62 37 41 70 82 47 52 49
a. Compute the variance and standard deviation for this data set. s2 = 279.111; s = 16.707
b. If a very expensive cheese with a cost per slice of 150 cents was added to the data set, how would the values of the mean and standard deviation change?
a. The variance of the data set is 279.111 and the standard deviation is 16.707.
b. Adding an expensive cheese increases the mean to 55.9 and the standard deviation to 48.53.
a. To compute the variance and standard deviation for the given data set, we can use the following formulas:
Variance (s²) = [(Σx²) - (Σx)² / n] - 1
Standard Deviation (s) = √(Variance)
Using the given data set: 29, 62, 37, 41, 70, 82, 47, 52, 49
Step 1: Calculate the mean (x) of the data set.
Mean (x) = (Σx) / n
Σx = 29 + 62 + 37 + 41 + 70 + 82 + 47 + 52 + 49 = 409
n = 9 (number of data points)
Mean (x) = 409 / 9 = 45.44 (rounded to two decimal places)
Step 2: Calculate the sum of squares (Σx²) for the data set.
Σx² = 29² + 62² + 37² + 41² + 70² + 82² + 47² + 52² + 49² = 151509
Step 3: Substitute the values into the variance formula and calculate the variance.
Variance (s²) = [(Σx²) - (Σx)² / n] - 1
Variance (s²) = (151509 - (409)² / 9) / (9 - 1) = 279.111 (rounded to three decimal places)
Step 4: Calculate the standard deviation by taking the square root of the variance.
Standard Deviation (s) = √(Variance)
Standard Deviation (s) = √279.111 = 16.707 (rounded to three decimal places)
b. If a very expensive cheese with a cost per slice of 150 cents was added to the data set, the values of the mean and standard deviation would change. To find the new mean and standard deviation, we need to incorporate the additional data point and recalculate.
New Σx = Σx + 150 = 409 + 150 = 559 (updated sum of the data points)
New n = n + 1 = 9 + 1 = 10 (updated number of data points)
New Mean (x) = New Σx / New n = 559 / 10 = 55.9 (rounded to one decimal place)
The addition of the expensive cheese increased the mean.
To calculate the new variance and standard deviation, we follow the same steps as in part a using the updated Σx and n values:
New Σx² = Σx² + (150)² = 151509 + 22500 = 174009
New Variance (s²) = [(New Σx²) - (New Σx)² / New n] - 1 = (174009 - (559)² / 10) / (10 - 1) = 2355 (rounded to three decimal places)
New Standard Deviation (s) = √New Variance = √2355 = 48.53 (rounded to two decimal places)
Therefore, the addition of the expensive cheese increased both the mean and the standard deviation of the data set.

If you roll a six sided die, what is the probability that you do not roll a one or two?
Answer:
66.6%
Step-by-step explanation:
You have a 1/6 chance to roll any number. That is a 16.6% chance per number.
So, that means you have a 4/6 (2/3 simplified) probability of not rolling a one or two. That is a 66.6% chance.
[NOTE: The '6' at the end of '16.6%' and '66.6%' is a repeating decimal]

Angle ∠B is a right-angle then the measure of angle ∠A is 43.6 degrees and the measure of angle ∠C is 46.4 degrees.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
The triangle ΔABC is given.
The angle ∠B is a 90°.
Then the value of the angle ∠C will be
[tex]\rm C = \sin ^{-1} \dfrac{21}{29}\\\\C = 46.40^o[/tex]
Then the value of the angle ∠A will be
∠A + ∠C = 90°
∠A + 46.40° = 90°
∠A = 43.6°

If p is prime, then there exists a field of order p². O True False
The statement "If p is prime, then there exists a field of order p²" is true. For any prime number p, there exists a finite field of order p².
Is it true that if p is prime, there exists a field of order p²?Yes, it is true that if p is a prime number, then there exists a field of order p². In mathematics, a field is a specific type of algebraic structure with two operations, addition and multiplication, that satisfy certain properties. The order of a field refers to the number of elements in the field. For any prime number p, there exists a unique finite field of order p², often denoted as GF(p²) or Fp². This field consists of p² elements and is crucial in various areas of mathematics, such as number theory, cryptography, and coding theory.
