c) We have to find the probability that a new patient will be assigned to a male doctor.
In this case, we have 3 male doctors out of 7, so the probability can be expressed as 3/7.
We can find the probability as a percentage as:
\(\begin{gathered} P(m)=\frac{3}{7}*100\% \\ P(m)=0.429*100\% \\ P(m)=42.9\% \end{gathered}\)Answer: c) the probability is 3/7 or, expressed as percentage, 42.9%.

Step-by-step explanation:
If you do 15x12 which is the formula for area for a rectangle, you get 180. That's only the area of one rectangle but if you multiply it by 3 you get 540 for the areas added together.
Answer:

Shireen decided to deposit her graduation gift money in two different savings accounts. Account X has an interest rate of .5% and Account Y has an interest rate of .25%. Altogether, she received $5000 from graduation. If after the first year Her interest earned was $21.25, how much was deposited into each account?a. Define your variables by assigning them to the real-world quantities in the problem.b. Write a system of equations in standard form you can use to solve for those quantities.c. Calculate the x and y intercepts for both equations.d. How much was deposited in each account? Use whatever method you want to solve thesystem of equations.
Answers
Let x= be the amount in the account with .5%
Let y be the amount in the account with .25%
We know that interest is
I = PRT
I = 21.25 and time is 1 year so t=1
I = x(.005)(1) + y (.0025)
We also know that the amount invested is 5000
x+y = 5000
The system of equations is
21.25 = .005x + .0025y
x+y = 5000
21.25 = .005x+.0025y
Let x = 0
21.25 = .0025y
21.25/.0025 =y
The y intercept is 8500
Let y =0
21.25 = .005x
21.25/.005 =x
The x intercept is 4250
x+y = 5000
Let x = 0
The y intercept is 5000
Let y =0
The x intercept is 5000
Using substitution
x = 5000-y
21.25 = .005(5000-y) + .0025y
21.25 = 25 - .005y +.0025y
21.25-25 = -.0025y
-3.75 = -.0025y
-3.75/-.0025 = y
1500 = y
Now find x
x+y = 5000
x+1500=5000
x = 5000-1500
x = 3500
The diameter of the moon is
3,474,000 meters. Which is the
best estimate of the diameter of the
moon?
Answers
The best estimate of the diameter of the moon is 3.474×10⁶.
The best estimate of the diameter will be calculated by converting the number into scientific notation. To convert the number into scientific notation it is broken into two parts.
First number is coefficient which has to range between 1 and 10. So, as per the digits, 3.474 will be the coefficient.
The 10 will be written along with exponent. There are three digits after the decimal followed by three zeroes. Therefore, the 10 and exponent will be written as 10⁶.
So, the complete number estimating the diameter of moon is 3.474×10⁶.

Yvonne wants to use a dissection argument to justify the formula for the area of a circle. She dissects the circle into congruent sectors and reassembles the sectors as a parallelogram-like figure. The diagram below shows the arrangement for a circle dissected into 8 sectors. M Height Base Yvonne knows that as the number of sectors of the circle increases, the reassembled figure becomes closer and closer to an actual parallelogram so that it can be used to determine the area of the circle. Determine the value of each characteristic of the parallelogram in the table below. Select the best value for each characteristic.base of the parallelogram height of the parallelogram area of the parallelogram
Answers
Each sector is formed like a triangle with a circle base. The sum of all the bases should be equal to half the length of the circle's circumference, this is calculated with the following expression:
\(\text{base}=\frac{2\pi r}{2}=\pi r\)This is the base of the parallelogram.
The height of each triangle is the radius of the circle, therefore:
\(\text{height}=r\)The area of the parallelogram is the product of the base and the height.
\(\text{Area =}\pi r^2\)So the base is pi*r;
The height is r;
The area is pi*r².

Part 3 of 4 (c) Find the probability that or more of the flights were on time. The probability that or more of the flights were on time is . Part 4 of 4 (d) Would it be unusual for or more of the flights to be on time
Answers
Answer:
a) \(P(X = n) = (0.85)^{n}\)
b) \(P(X = x) = C_{n,x}.(0.85)^{x}.(0.15)^{n-x}\)
c)
\(P(X \geq x) = P(X = x) + P(X = x+1) + ... + P(X = n)\)
For each value, we use
\(P(X = x) = C_{n,x}.(0.85)^{x}.(0.15)^{n-x}\)
d) If \(x > E(X) + \sqrt{V(X)}\), yes, otherwise no
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it arrived on time, or it did not. Flights are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
And p is the probability of X happening.
The expected value of the binomial distribution is:
\(E(X) = np\)
The standard deviation of the binomial distribution is:
\(\sqrt{V(X)} = \sqrt{np(1-p)}\)
A measure is said to unusual if it is more than 2.5 standard deviations from the mean.
85% of recent flights have arrived on time.
This means that \(p = 0.85\)
(a) Find the probability that all of the flights were on time.
This is \(P(X = n)\), in which n is the size of the sample studied.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = n) = C_{n,n}.(0.85)^{n}.(0.15)^{n-n}\)
\(P(X = n) = (0.85)^{n}\)
(b) Find the probability that exactly x of the flights were on time.
Exactly x of the flights: So
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = x) = C_{n,x}.(0.85)^{x}.(0.15)^{n-x}\)
(c) Find the probability that x or more of the flights were on time.
This is
\(P(X \geq x) = P(X = x) + P(X = x+1) + ... + P(X = n)\)
For each value, we use
\(P(X = x) = C_{n,x}.(0.85)^{x}.(0.15)^{n-x}\)
(d) Would it be unusual for x or more of the flights to be on time?
If \(x > E(X) + \sqrt{V(X)}\), yes, otherwise no

The solution that can be used to fill in location A is 45%.
In this case, Rena is trying to make a 45% solution. The alligation diagram shows two solutions with concentrations of 20% and 45%. The concentration at location A represents the concentration of the final mixture.
To determine the concentration at location A, we can visually observe the positioning of the concentrations on the diagram. The closer a concentration is to location A, the more it contributes to the final mixture.
In this case, the concentration of 45% is closer to location A than the concentration of 20%.
This means that more of the 45% solution should be used in the mixture to achieve a 45% concentration.
Therefore, the solution that can be used to fill in location A is 45%.

which statement best describes the end behavior of the following function? F(x)=2x^4-x^3+5x-9
Answers
Here we have a polynomial of even degree with positive leading coefficient, so the end behavior is:
as x → ∞, f(x) → ∞
as x → -∞, f(x) → ∞
How is the end behavior of F(x)?
Here we have the function:
F(x) = 2x^4 - x^3 + 5x - 9
For any polynomial of even degree, we will have the same end behavior in both ends of the domain.
If the leading coefficient is positive, in both ends the function will tend to infinity.
If the leading coefficient is negative, in both ends the function will tend to negative infinity.
In the case of our function:
F(x) = 2*x^4 - x^3 + 5x - 9
We can see that the leading coefficient is 2, so it is positive, which means that the end behavior is:
