The probability that an event will occur is determined by the likelihood of each possible outcome and the number of possible outcomes.

In this scenario, the binomial variable is the number of wins for the two people with equal skills playing a game for 50 days.

The probability of success (a win) is the same for each game, and the number of trials is fixed at 50, making this a binomial experiment.

Probability is the measure of how likely it is that an event or outcome will occur. It is usually expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that it is certain to occur. The probability that an event will occur is determined by the likelihood of each possible outcome and the number of possible outcomes.

The total amount earned by Kedar is $2285.1.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Kedar's salary is $2200. The commission amount is 3.7%. The total earnings will be calculated as:-

Total earning = 2200 + ( 4500 - 2200 ) x 0.037

Total earning = 2200 + 85.1

Total earning = $2285.1

Therefore, the total amount earned by Kedar is $2285.1.

Answer:

To find the measures of each angle, we first need to determine the total measure of all three angles in the triangle. Since the sum of the measures of the angles in any triangle is 180 degrees, we can find the total measure of all three angles by multiplying the ratio 2:5:3 by 180.

We can find the total measure of all three angles by using the rule of three.

2/5+5/3+3/2 = 180/x

Solving for x:

x = 1802532/ (2+5+3) = 180*60/10 = 1080

So, the total measure of all three angles is 1080 degrees.

Then, we can find the measure of each angle by multiplying the fraction of the ratio that represents that angle by the total measure of all three angles.

The measure of the first angle is: 2/10 * 1080 = 216 degrees

The measure of the second angle is: 5/10 * 1080 = 540 degrees

The measure of the third angle is: 3/10 * 1080 = 324 degrees

Saving enhances emotions of stability and peace of mind and offers a financial "backstop" for life's uncertainties. Savings can serve as the "seed money" for higher-yielding assets like stocks, bonds, and mutual funds if an appropriate emergency fund has been developed.

This calculation can be used to determine the payback period

Payback of month = [tex]\frac{cost of invesment}{Saving during the year}[/tex] × months in year

= [tex]\frac{35000}{40000}[/tex] × 12

The vertex shows that the overall value of home in 21 years after 2020,i.e., in 2041 is 125210 dollars.

What is quadratic equation in math?

A polynomial equation of the second degree, or a quadratic, must contain at least one squared term to be considered a quadratic.            

                         Equations with quadratic terms are another name for them. The quadratic equation is expressed in its general form as ax2 + bx + c = 0. When the numerical coefficients a, b, and c are present and x is an unknown variable.

The overall value of a home is modeled by

v(x) = 210x²-4400x+125000

This is a quadratic function which is of the form ax²+bx+c ⇒ x²+(b/a)x+(c/a)

The vertex of a quadratic function is the point where the rate of change of function is zero.

x-coordinate of the vertex is given by (-b/2a) and the y-coordinate is the corresponding y-value to the x-coordinate of the vertex.

Hence here, x-coordinate = -(-4400/210) = 20.95 ≈ 21

y-coordinate = 210 x 21²-4400 x 21+125000 = 125210

The vertex is (21, 125210).

Answer: 5,211 dollars

Step-by-step explanation: Our first approch to this is to find the number of Gala and Honeycrisp(HC) Trees are there.

We are given the number of total trees (81 trees) and the ratio between Gala and HC trees  (5 to 4). This means for every set of 9 trees, 5 will be Gala and 4 will be HC. We can create the equation

9x = 81

5x = number of gala trees

4x = number of HC trees

x represents the number of sets of 9 trees so in this case, there will be 9 sets if you solve for x.

9x = 81

divide both sides by 9

x = 9

We can plug this back into the 2 other equations that represent the number of each tree so

5(9) = 45 gala trees,

4(9) = 36 HC trees

This makes sense since 45+36 = 81 so it adds up

Now to find the amount of money just take the amount of each trees we have and multiply it by the pounds each tree made then multiply it by the price each pound makes.

45 gala trees * 25 pounds * 1.52 dollars = 1,710 dollars

and

36 HC trees * 25 pounds * 3.89 dollars = 3,501 dollars

Finally, add both of them up to get the total profit

1,710 + 3,501 = 5211 dollars

The correctly expresses that algorithm in pseudocode

numFreezing ← 0

numDays ← 0

FOR EACH temp IN temps

IF (temp ≤ 32)

{numFreezing ← numFreezing + 1}

{numDays ← numDays + 1}

For this situation, Pseudocode B would be appropriate. Two variables are created by this code for the overall number of days (numDays) and the number of freezing days (nonfreezing). Then, it does a loop over the complete collection of data to determine whether each temperature is less than or equal to 32 degrees.

If so, it adds it to nonfreezing; otherwise, it skips the step while still increasing the number of days after each loop by 1. Contrary to answer A, which prints the ratio after each loop iteration, this answer only prints the ratio once the loop has been completed.

Their algorithm will operate on a list of temperatures for each day in the month. It must keep track of how many temperatures are below or equal to 32. Once it's done processing the list, it must display the ratio of freezing days over total days.

For $25,000, a brand-new car is bought. The automobile loses 14% of its value annually.

x=6.3.

Using the conditions stated, come up with:

20500 . 1 - 14% x 7900

Determine the difference or total:

First, we convert R percent to r a decimal,

which is 14%/100, which is 0.14 each year. Next, we solve for t by using the ratio

(1/0.14)(20500/7900) - 1),

which gives us 11.39 years.

At a basic interest rate of 14% per year, it will take 11.39 years to accumulate a total of $20,500.00 from the principle and interest on a $7,900.00 starting point (about 11 years 5 months).

The situations described are A : subjective, B : classical, C : empirical, D : subjective and E : empirical.

In Classical probability, probability of an event is found using the basic probability formula assuming the outcomes in a sample space are equally likely.

In Empirical probability, experiment is actually done and record the outcomes.

In subjective probability, probability is based completely on the intuition or guess.

A : Recruiters are making a wild guess that there is an 80% chance that remote hiring will increase in 2023. This is a subjective probability.

B : This is classical probability because the probability is found by the basic formula, Number of nurses divided by total number of medical employees = 10/20 = 0.50.

C : This is an empirical probability because the experiment of survey is already done to find that there is a 73% chance that a randomly selected adult will say that he/she is playing games on mobile phones.
