Using the binomial distribution, it is found that there is a 4% probability of Anne winning two matches.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
She plays two matches, hence n = 2.She wins a match 20% of the time, hence p = 0.2.The probability that he wins two matches is P(X = 2), hence:
[tex]P(X = 2) = C_{2,2}.(0.2)^{2}.(0.8)^{0} = 0.04[/tex]

The point (-5, 6) is on a circle with a center (-1, 3).
Find the radius of the circle.
Write the standard equation of the circle.
Graph the circle.
Step-by-step explanation:
The distance from the radius to a point on the circle is equal to the radius. After using the distance formula, we get that the radius is 5.
Using the fact that the circle with center (h,k) and radius r is (x-h)^2 + (y-k)^2 = r^2, we get that the equation is:
(x+5)^2 + (y-6)^2 = 25
Harold randomly selected one square tile and one round tile from the sets shown below. what is the probability that harold selected a pink square tile, and either a red or a blue round tile? square tiles: 20 green, 16 pink, 9 red, 10 yellow, 5 blue.round tiles: 5 black, 4 pink, 9 red, 6 blue, 3 yellow, 8 green, 1 white. a. 3/5 b. 14/60 c. 1/9 d. 4/45
The probability that Harold selected a pink square tile, and either a red or a blue round tile is 1/9.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
Considering the selections are independent, their combined probability is the product of the probabilities of the individual events.
P(pink square) = (pink squares) / (squares) = 16/60 = 4/15
P(red or blue round) = (red or blue rounds) / ( rounds) = 15/36
Then, the Total probability
P(E) = (4/15)(15/36)
P(E) = 4/36
P(E) = 1/9
So, the probability that Harold selected a pink square tile, and either a red or a blue round tile is 1/9.

In computer science, functions are collections of code that can be used and re-utilised in greater codes. Functions are formed by inputs, a procedure and an output.
In this question we must analyze a recursive function, recursive functions are functions that creates a loop with the function itself, that is, the function uses itself as an output, until desired output is done.
After performing desktop testing, we conclude that the result of the recursive function mystery (m) is k. [tex]\blacksquare[/tex]

The maximum angle of elevation for a ramp designed to be safe for a motorized wheelchair is 7.1°.
Is the ramp at the local library safe for motorized wheelchairs? Explain your answer.
Answer: Not safe
Step-by-step explanation:
Let the angle of elevation of the ramp be θ, then:
[tex]\begin{aligned}&\sin \theta=\frac{1.5}{10}=0.15 \\&\theta=\sin ^{-1}(0.15) \approx 8.63^{\circ}\end{aligned}[/tex]
But the maximum angle for the ramp cannot exceed 7.1°. The calculated angle of elevation will make it difficult, if not impossible, for motorized wheelchairs to get up the ramp.
Therefore, the ramp at the local library is not safe for motorized wheelchairs

- 3x + 4y = 12
2.x + 2y = -22
Answer:
x = -8
y = -3
Step-by-step explanation:
So first you're going to want to get x or y by itself using elimination or substitution. I used elimination to get x by itself.
You can multiply the second equation (2x + 2y = -22) by -2 so you can eliminate the y's. When you multiply it, you get -4x - 4y = 44
Then, you can add -3x + 4y = 12 and -4x - 4y = 44. The y's cancel out to leave -7x = 56. Divide both sides by -7 to get x = -8.
Now, you can plug in -8 for x in either one of the equations. I plugged it into the second equation to make it 2(-8) + 2y = -22.
2 · -8 = -16.
-16 + 2y = -22. Add 16 to both sides to get 2y = -6. Divide both sides by to get y = -3.

For the first question it's 52.99 cm^3 because the formula for volume of a cylinder is V=πr^2h.
The second question is 722.57 or 722 cm^2 because the formula for surface area is A=2πrh+2πr^2.
hope it helps!
Answer:
For question 3: 52.9875 cm^3 or 52.99 cm^3.
For question 4: 1,413 cm^3.
Step-by-step explanation: To find the volume of a cylinder, you need the area of the base times the height. We don't have the area of the base, but we can find out by using the formula 3.14 x r^2 where r is the radius, which is 1.5 for question 3 and 5 for question 4. It should look like this:
For question 3: 3.14 x 1.5^2 = 7.065.
For question 4: 3.14 x 5^2 = 78.5.
When you find the area of the base, you multiply it by the height, which is 7.5 for question 3 and 18 for question 4. It should look like this:
For question 3: 7.065 x 7.5 = 52.9875 or 52.99.
For question 4: 78.5 x 18 = 1,413.
Therefore, 52.9875 cm^3 or 52.99 cm^3 is your answer for question 3 and 1,413 cm^3 is your answer for question 4.

Billy invested $1000.00 into a savings account on the day his daughter was born. The money is being saved for her college tuition. Billy leaves the money in a savings account until his daughter's 18th birthday. The account earned a simple interest rate of 6.925%. What is the total amount in the account?
Answer:
Let the amount invested at 3% = x
Let the amount invested at 6% = y.
From the total amount invested, we get this equation.
x + y = 18
Now we look at the interest earned.
The 3% account earns 0.03x
The 6% account earns 0.06y
5% on the entire amount is 0.05 * 18 = 0.9
This gives us the second equation.
0.03x + 0.06y = 0.9
Now we have a system of 2 equations in 2 unknowns.
x + y = 18
0.03x + 0.06y = 0.9
Solve the first equation for y:
y = 18 - x
Replace 18 - x for y in the second equation.
0.03x + 0.06y = 0.9
0.03x + 0.06(18 - x) = 0.9
0.03x + 1.08 - 0.06x = 0.9
-0.03x + 1.08 = 0.9
-0.03x = -0.18
x = 6

The scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.
What is the dilation of the figure?Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.
Point c is the center of dilation. Line segment BA is dilated to create line segment b prime, a prime. The image of the given problem is attached below. The length of CA is 4.
