Two of Mr. Barnaby's cats just had kittens. The line plot shows the weights of the 8 kittens at 3 weeks old. What is the average weight, in kilograms, among all of the kittens?
Answer:
\(\text{Average Weight}=\frac{1}{8}\sum\limits^{8}_{i=1}{X_{i}}\)
Step-by-step explanation:
The average value of a data set is the representation of the central tendency of the data set, i.e. the average of a set is the measure of center.
The formula to compute the average of a data set is:
\(\text{Average}=\frac{1}{N}\sum\limits^{N}_{i=1}{X_{i}}\)
Here,
N = number of observation in the data set
\(\sum\limits^{N}_{i=1}{X_{i}}\) = sum of all the observations
It is provided that the line plot shows the weights of the 8 kittens at 3 weeks old.
So, there are a total of N = 8 kittens.
The formula to compute the average weight is:
\(\text{Average Weight}=\frac{1}{8}\sum\limits^{8}_{i=1}{X_{i}}\)

Sonya surveyed 550 people on their favorite sport. 46% of people like soccer, 24% of people like baseball, and the rest like football. What PERCENTAGE of people like football?
Answer:
the percentage of people who likes football is 30%
Step-by-step explanation:
The computation of the percentage of people who likes football is shown below:
Let us suppose the total people like sport be 100
Now the percentage of people who like football is
= Total people - soccer people - baseball
= 100% - 46% - 24%
= 30%
Hence, the percentage of people who likes football is 30%
a boy has 2 red , 2 yellow and 5 green marbles. in how many ways can the boy arrange the marbles in a line if all 9 marbles have different sizes?
By using the concept of permutation, it can be calculated that
Number of ways in which the marbles of different sizes can be arranged in a line = 362880
What is permutation?
The technique which is used to determine the possible arrangements that can be made among the members of the set when the order of arrangement is taken into account
Here the concept of permutation is used
Number of red marbles = 2
Number of yellow marbles = 2
Number of green marbles = 5
Total number of marbles = 2 + 2 + 5 = 9
Here, the marbles are of different sizes
So the first marble have 9 choices, second marble have 8 choices and so on
Number of ways in which the marbles of different sizes can be arranged in a line = 9 \(\times\) 8 \(\times\) 7 \(\times\) .... \(\times\) 1
= 9!
= 362880

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
3 / 4 y = 9
Step 1: Multiply both sides by 4/3.
(4 / 3 ) * ( 3 / 4 y ) = ( 4 / 3 ) * ( 9 )
y = 12

var(x)=e(x^2)-e(x)^2 proof
We have proved that the expression \(Var(x) = E(x^2) - [E(x)]^2.\)
How to prove the equation?To prove that \(Var(x) = E(x^2) - [E(x)]^2\), where \(Var(x)\) represents the variance of a random variable x and E(x) represents the expected value of x, we can start by using the definition of variance:
\(Var(x) = E[(x - E(x))^2]\)
Expanding the square:
\(Var(x) = E[x^2 - 2x*E(x) + [E(x)]^2]\)
Using linearity of expectations, we distribute the expectation operator:
\(Var(x) = E(x^2) - 2E(x*E(x)) + E([E(x)]^2)\)
Now, let's focus on the term E(x*E(x)). Since E(x) is a constant with respect to the inner expectation operator, we can take it out:
\(E(x*E(x)) = E(x) * E(E(x))\)
The inner expectation, E(E(x)), is just the expected value of a constant, which is equal to that constant:
\(E(E(x)) = E(x)\)
Substituting this back into the equation, we have:
\(Var(x) = E(x^2) - 2E(x*E(x)) + E([E(x)]^2)\)
\(= E(x^2) - 2E(x*E(x)) + E(x^2)\)
Now, consider the term \(E(x*E(x))\). This can be written as:
\(E(x*E(x)) = E(E(x^2|x))\)
This is the conditional expectation of \(x^2\) given x. However, when we take the unconditional expectation E, the conditional expectation collapses to the unconditional expectation of \(x^2\):
\(E(x*E(x)) = E(x^2)\)
Substituting this back into the equation, we get:
\(Var(x) = E(x^2) - 2E(x*E(x)) + E(x^2)\)
\(= E(x^2) - 2E(x^2) + E(x^2)\)
\(= E(x^2) - E(x^2)\)
\(= E(x^2) - [E(x)]^2\)
Hence, we have proved that \(Var(x) = E(x^2) - [E(x)]^2.\)

a loan payment of $1000 was due 60 days ago and another payment of $1200 is due in 30 days. what's the single payment 90 days from now is required to pay off the two obligations if interest is to be 12% and agreed focal date is on 90 days from now?
Present value of Loan payment 1 = \($1000 / (1 + (0.12/365))^{60\)
Present value of Loan payment 2 = \($1200 / (1 + (0.12/365))^{(-30)\)
The single payment required 90 days from now to pay off the two obligations would be the total present value calculated in Step 3.
To calculate the single payment required to pay off the two obligations with a 12% interest rate, we can use the concept of present value. Present value is the current worth of a future payment, taking into account the interest rate and time.
Let's break down the given information:
Loan payment 1: $1000 due 60 days ago
Loan payment 2: $1200 due in 30 days
To find the single payment required 90 days from now, we need to calculate the present value of each payment and then add them together.
Step 1: Calculate the present value of Loan payment 1.
The time period for Loan payment 1 is 60 days ago.
To bring it to the present, we need to calculate the interest accrued for 60 days at a 12% annual interest rate.
Step 2: Calculate the present value of Loan payment 2.
The time period for Loan payment 2 is 30 days in the future.
To bring it to the present, we need to calculate the interest accrued for 30 days at a 12% annual interest rate.
Step 3: Add the present values of Loan payment 1 and Loan payment 2.
Total present value = Present value of Loan payment 1 + Present value of Loan payment 2

You have round tables each seating 6 people. As your guests sit at the table, how many degrees must you rotate to look from the guest to their left to the guest to their right? (Hint: The interior angles of regular polygon measure ((n - 2) x 180) / n where n is the number of sides.)
To look from the guest to their left to the guest to their right at a round table seating 6 people, you need to rotate by 60 degrees.
For a regular polygon with n sides, the sum of its interior angles is given by ((n - 2) × 180) degrees. In the case of a round table seating 6 people, the table can be considered as a hexagon, which has 6 sides. Using the formula, we can calculate the sum of the interior angles:
((6 - 2) × 180) / 6 = (4 × 180) / 6 = 720 / 6 = 120 degrees
Since the table forms a complete circle, the sum of the interior angles is divided equally among the guests. Therefore, each guest sits at an angle of 120 degrees. To look from the guest to their left to the guest to their right, you need to rotate by the angle between adjacent guests, which is half of the angle they sit at:
120 / 2 = 60 degrees
Thus, to look from the guest to their left to the guest to their right at a round table seating 6 people, you need to rotate by 60 degrees.

which of the following is not a part of the business cycles that occur in economies over time?
The business cycle is a recurring pattern of economic expansion and contraction that occurs in economies over time. Each business cycle typically consists of four phases: expansion, peak, contraction, and trough.
The peak is the highest point of economic activity within a business cycle. It marks the end of the expansion phase and the beginning of the contraction phase. During this phase, economic indicators, such as GDP, employment, and consumer spending, reach their highest levels.
The peak is indeed a part of the business cycle. It represents the phase of maximum economic activity and is characterized by various indicators reaching their highest points. This phase is followed by the contraction phase, where economic activity slows down. Therefore, the peak is a crucial element in understanding and analyzing business cycles.
