If radius of circle is tripled then area of circle will be increased by:9 times.

If the radius of a circle is tripled, then the new radius is three times the original radius, or R' = 3R, where R is the original radius and R' is the new radius. The area of a circle is given by the formula A = πR^2, where A is the area and R is the radius.

Substituting R' = 3R into the formula for the area of a circle, we get:

A' = πR'^2

= π(3R)^2

= 9πR^2

Therefore, the new area A' is 9 times the original area A. In other words, if the radius of a circle is tripled, the area of the circle will be increased by a factor of 9. This is because the area of a circle is proportional to the square of its radius.

Step-by-step explanation: Because 1,007 squared is 1,014,049 and the sum of 911 squared is 829,921 and then 829 squared is 687,241 then add 829,921+687,241=1,517,162 when it should equal 1,014,049 which is the amount of 1,007 squared to make it a right triangle.

The solution is : no, it does not form a right triangle.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

Players A and B withdraw balls from the urn consecutively until a read ball is selected, the probability that player A selects the red ball is approximately 0.408.

To find the probability that player A selects the red ball, we can use the law of total probability and consider all the possible ways the game could end. A selects the red ball on the first draw. The probability of this is simply the proportion of red balls in the urn, which is 3/10.

A selects a black ball on the first draw, followed by B selecting a black ball on their turn, and so on, until A finally selects the red ball. The probability of this is:

(7/10) * (6/9) * (5/8) * ... * (1/4) * (3/7)

Notice that the probability of selecting a black ball decreases by one after each turn, since the total number of balls in the urn decreases by one and the number of black balls decreases by one.

The probability of selecting the red ball on the last turn (after all the black balls have been selected) is 3/3 = 1. We multiply all these probabilities together to get the total probability of this sequence of events.

A selects a black ball on the first draw, followed by B selecting a black ball on their turn, and so on, until B finally selects the red ball. The probability of this is:

(7/10) * (6/9) * (5/8) * ... * (2/4) * (3/6)

Notice that the probability of selecting a black ball decreases by one after each turn, just like in the previous case. However, the probability of B selecting the red ball on their turn is now 3/6, since there are only six balls left in the urn at this point. We multiply all these probabilities together to get the total probability of this sequence of events.

Adding up these three probabilities, we get:

The two numbers, then, are 86 and 61.The two numbers can be found by using basic algebra.

The two numbers can be found by using basic algebra. To solve for the two numbers, we can set up two equations, one for the sum and one for the difference. For the sum, we can set up the equation: x + y = 147. For the difference, we can set up the equation: x - y = 25. We can then solve for x by adding y to both sides of the equation for the difference, so x = 25 + y. We can then substitute this value for x in the equation for the sum, so 25 + y + y = 147, or 2y = 122, and y = 61. We can then substitute this value for y in the equation for x, so x = 25 + 61, or x = 86. The two numbers, then, are 86 and 61.

Answer:

Step-by-step explanation:

The interest rate of 1.25% compounded monthly means that the interest earned each month is 1.25% of the current balance. Here's how you can calculate the final balance in the account after 20 years:

First, calculate the interest earned each month: $200 * 1.25% = $2.50

Then, add the interest earned to the monthly deposit to get the new balance: $200 + $2.50 = $202.50

Repeat this process for 240 months (20 years x 12 months/year).

The final balance in the account after 20 years would be approximately $71,934.24.

To find the total money you will put into the account, simply multiply the monthly deposit by the number of months: $200 * 240 = $48,000.

To find the total interest earned, subtract the initial deposit from the final balance: $71,934.24 - $48,000 = $23,934.24

So, in 20 years, you will have put a total of $48,000 into the account, and you will have earned a total of $23,934.24 in interest.

What is word problem?

A word problem is a type of mathematical problem that is presented using words instead of or in addition to mathematical symbols and equations. Word problems often describe a real-world scenario or situation, and they require the solver to use math skills and critical thinking to identify the relevant information, determine the mathematical operation or operations required, and arrive at a solution to the problem.

Let's assume that the number of movies Uncle Harry rented is "m" and the number of games is "g". We want to find the values of "m" and "g".

From the problem statement, we know that:

The total number of movies and games rented is 12: m + g = 12

The cost of each movie is $3.99: 3.99m

The cost of each game is $4.50: 4.5g

The total cost before tax is $49.92: 3.99m + 4.5g = 49.92

We can use the first equation to express "m" in terms of "g":

m = 12 - g

Substituting this expression for "m" in the second equation, we get:

3.99(12 - g) + 4.5g = 49.92

Expanding the brackets and simplifying, we get:

47.88 - 3.99g + 4.5g = 49.92

0.51g = 2.04

g = 4

So Uncle Harry rented 4 games, and using the first equation, we find that he also rented 8 movies.

Therefore, the Lupine family has 8 horror movies and 4 gory games for their vacation.

The probability of an event happening is the measure of how likely that event is to occur.

In this case, we need to find the probability of selecting a jury of 12 women from a pool of 30 people. To calculate this probability, we can use the formula:

Probability = Number of favorable outcomes / Total number of outcomes

The total number of outcomes is the number of ways in which we can select 12 people from a pool of 30. We can calculate this number using the combination formula:

Total number of outcomes = C(30,12) = 30! / (12! * (30-12)!) = 28,238,760

Now, we need to calculate the number of favorable outcomes, which is the number of ways in which we can select 12 women from a pool of 18. We can calculate this number using the combination formula as well:

Number of favorable outcomes = C(18,12) = 18! / (12! * (18-12)!) = 18,564

Therefore, the probability of selecting a jury composed of 12 women is:

The expected value of the sample mean amount of money spent on books is equal to the population mean, which is $400.

This is a property of the sampling distribution of the sample mean, which states that the mean of all possible sample means is equal to the population mean.

In other words, if we take all possible random samples of size 100 from the population of undergraduate students, and calculate the mean amount of money spent on books for each sample, then the average of all these sample means will be $400.

The expected value of the sample mean amount of money spent on books can be calculated using the formula:

E(X) = μ

where X is the sample mean, and μ is the population mean.

In this case, the population mean is given as $400. Therefore, the expected value of the sample mean amount of money spent on books is also $400.

However, we can also calculate the standard error of the mean (SE) to get a measure of the variability of the sample mean. The formula for SE is:

[tex]SE = σ / sqrt(n)[/tex]

where σ is the population standard deviation, and n is the sample size.

Substituting the values, we get:

[tex]SE = 80 / sqrt(100) = 8[/tex]

This property is true regardless of the sample size, as long as the sample is randomly selected and independent. However, as the sample size increases, the sampling distribution of the sample mean becomes more normal and the standard error of the mean decreases, making the sample mean a more precise estimate of the population mean.
