There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.

The area of the third side of the triangle is either 20 square unit or 12 square units.

Triangle:

in math, triangle refers a simple closed curve made of three line segments and it has three vertices, three sides and three angles.

Given,

Two sides of a right triangle measure 2 units and 4  units.

And we need to find the area of the square that shares a side with the third side of the triangle  ​

Let us consider is  Two sides of a right triangle measure 2 units and 4  units.

Here if sides are perpendicular sides, then by using Pythagorean theorem

=> third side² = 2² + 4²

When we simplify this one, then we get,

=> third side² = 4 + 16

So, the  third side² = 20

Then the area of the square that shares a side with the third side of the triangle =  third side² = 20 sq units

Similarly, if 4  units is hypotenuse side, then by using Pythagorean theorem, the third side is calculated as,

=> third side² = 4² - 2²

And when we simplify this one, then we get,

=> third side² = 16 - 4

Therefore, the third side² = 12

And the area of the square that shares a side with the third side of the triangle =  third side² = 12 sq units

The proababilities are: i) P(Aᶜ) = 0.6, ii) P(Bᶜ) = 0.4

iii) Probability that exactly one of the events A, B occurs = 0.7

Let A and B be any two disjoint events such that P(A) = 0.4 and P(A ∪ B) = 0.7. We need to find the following probabilities:

i) P(Aᶜ): This is the probability of the complement of event A, which represents the probability of not A occurring. Since A and B are disjoint, Aᶜ and B are mutually exclusive and their union covers the entire sample space.

Therefore, P(Aᶜ) = P(B) = 1 - P(A) = 1 - 0.4 = 0.6.

ii) P(Bᶜ): This is the probability of the complement of event B, which represents the probability of not B occurring. Since A and B are disjoint, Bᶜ and A are mutually exclusive and their union covers the entire sample space.

Therefore, P(Bᶜ) = P(A) = 0.4.

iii) Probability that exactly one of the events A, B occurs: This can be calculated by subtracting the probability of both events occurring (P(A ∩ B)) from the probability of their union (P(A ∪ B)).

Since A and B are disjoint, P(A ∩ B) = 0.

Therefore, the probability that exactly one of the events A, B occurs is P(A ∪ B) - P(A ∩ B) = P(A ∪ B) = 0.7.

To summarize:

i) P(Aᶜ) = 0.6

ii) P(Bᶜ) = 0.4

iii) Probability that exactly one of the events A, B occurs = 0.7

Note: The provided values of P(A), P(A ∪ B), and the disjoint nature of A and B are used to derive the above probabilities.

Aaron's taxable income is negative (-$10,100), it means that he does not have any taxable income.

To determine the amount of taxable income for Aaron Rentz in 2020, we need to consider his wages, interest income, and any deductions or credits he may be eligible for.

From the given information, Aaron has $900 of wages and $1,400 of interest income.

In 2020, the standard deduction for a single individual was $12,400. Since Aaron is a qualifying child of his parents, he may not be able to claim his own personal exemption.

To calculate Aaron's taxable income, we subtract the standard deduction from his total income:

Taxable Income = Total Income - Standard Deduction

Taxable Income = $900 + $1,400 - $12,400

Taxable Income = $2,300 - $12,400

Taxable Income = -$10,100

Since Aaron's taxable income is negative (-$10,100), it means that he does not have any taxable income.

While a high p-value indicates that there is not enough evidence to suggest a significant difference.

To determine whether there is a significant difference between how the boys and girls scored, Matt can use a statistical measure called a "p-value." The p-value is a number that indicates the probability of obtaining a difference as large as or larger than the one observed, assuming that there is no actual difference between the two groups being compared.

In this case, Matt can calculate the p-value by performing a statistical test, such as a t-test or an analysis of variance (ANOVA), on the scores of the boys and girls. The test will compare the means of the two groups and determine whether the difference between them is statistically significant or just due to chance.

If the p-value is less than a predetermined level of significance (usually 0.05 or 0.01), then Matt can conclude that there is a significant difference between how the boys and girls scored. This means that it is unlikely that the observed difference is due to chance, and that there is likely a real difference between the two groups.

On the other hand, if the p-value is greater than the level of significance, Matt cannot conclude that there is a significant difference between the two groups. This means that it is likely that the observed difference is due to chance, and that there is not enough evidence to suggest that there is a real difference between the two groups.

In summary, Matt can use a p-value calculated from a statistical test to determine whether there is a significant difference between how the boys and girls scored. A low p-value indicates a significant difference, while a high p-value indicates that there is not enough evidence to suggest a significant difference.

The probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is 2/3, in simplest form.

The table shows the information about the gym membership and lunch habits of 100 physical therapists.

Given that a physical therapist brings their lunch to work, we can use the information in the table to calculate the probability that they do not use the gym membership. To do this, we'll use the formula:

P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch)

We can use the information in the table to find the values of P(not using gym membership and brings lunch) and P(brings lunch).

P(not using gym membership and brings lunch) = 40/100 = 2/5

P(brings lunch) = 60/100 = 3/5

So, the probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is:

P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch) = (2/5) / (3/5) = 2/3

Therefore, the probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is 2/3, in simplest form.

Step-by-step explanation:

Ak is the event that the sum of the dots facing up is k, Bk is the event that the sum is greater than or equal to k, E is the event that the sum is even, and O is the event that the sum is odd. The total number of outcomes, which is 36.

a) To find P[Ak], we need to count the number of ways we can obtain a sum of k and divide by the total number of possible outcomes. This gives P[Ak] = (number of ways to obtain k)/(total number of outcomes) = (number of ways to obtain k)/36. Similarly, P[BX] is the probability of obtaining a sum greater than or equal to X, which is the same as the probability of obtaining a sum of X or more, so we can use the same approach as for P[Ak].

b) P[O|B8] is the probability that the sum is odd given that it is greater than or equal to 8. To find this, we can use Bayes' theorem: P[O|B8] = P[O and B8]/P[B8]. We can calculate P[O and B8] by counting the number of outcomes where the sum is odd and greater than or equal to 8, which is 10 (9, 11, ..., 19), and divide by the total number of outcomes that satisfy B8, which is 25 (8, 9, ..., 12). Therefore, P[O and B8] = 10/36 and P[B8] = 25/36, so P[O|B8] = (10/36)/(25/36) = 2/5.

c) P[A U A11\B8] is the probability that the sum is either 2, 3, ..., 11 or 12, but not 8. To find this, we can add the probabilities of the individual events and subtract the probability of their intersection: P[A U A11\B8] = P[A2] + P[A3] + ... + P[A11] + P[A12] - P[B8]. Note that P[B8] is the probability that the sum is 8 or more, so we can use our previous calculation to find this.

d) P[B80] is the probability that the sum is 8 or more. We can count the number of outcomes where the sum is 8 or more, which is 25 (8, 9, ..., 12), and divide by the total number of outcomes, which is 36.

e) P[B:|B-] is the probability that the sum is even given that it is odd. To find this, we can use Bayes' theorem: P[B:|B-] = P[B: and B-]/P[B-]. We can count the number of outcomes where the sum is even and odd, which is 18, and divide by the total number of outcomes where the sum is odd, which is 18 (1, 3, ..., 11), so P[B: and B-] = 18/36 = 1/2. We can also count the number of outcomes where the sum is odd, which is 18, and divide by the total number of outcomes, which is 36, to find P[B-].

f) P[E|B8] is the probability that the sum is even given that it is greater than or equal to 8. To find this, we can use Bayes' theorem: P[E|B8] = P[E and B.

Answer:

kinetic energy body when it hits the ground is 98000 joule

1000joule = 1 kilojoule

, kinetic energy body when it hits the ground is 98  kilo-joule

Step-by-step explanation:

conservation of energy states that total energy of a system remains constant.

Potential energy of body = mgh

m = mass

g = gravitational pull = 9/8 m/s^2

h = height

kinetic energy = 1/2 mv^2

where v is the velocity of body

________________________________________

Total energy for this at any point is sum of potential energy and kinetic energy

total energy at height h

v= 0

PE = 250*9.8*40= 98,000

KE = 1/2 m0^2  = 0

total energy at when ball hits the ground

h=0

PE = 250*9.8*0 =

KE = 1/2 mv^2  

_______________________________________\

Applying conservation of energy

Total energy at height h = total energy at ground

98000 = KE

Thus, kinetic energy body when it hits the ground is 98000 joule

1000joule = 1 kilojoule

, kinetic energy body when it hits the ground is 98  kilo-joule
