A survey asked 30 people what their favorite genre of television broadcasting was, and the results were tabulated above. Find the probability that a person chosen at random was female, given that they like comedy. Round the answer to the nearest hundredth.
The probability that a person chosen at random is female, given they like comedy, is approximately 0.53 or 53% .
First, let's find the total number of females who like comedy. In the Venn diagram, there are 8 females who like comedy. There are also 7 males who like comedy. So, there are 15 people who like comedy in total.
Next, we need to determine the total number of females. There are 16 females who like drama, and 4 females who like sports. Adding these together, we get 20 females in total.
Now, we can calculate the conditional probability that a female likes comedy given that she was chosen at random. The formula for conditional probability is P(A|B) = P(AnB) / P(B). In this case, event A is "being female" and event B is "liking comedy."
P(A|B) = (Number of females who like comedy) / (Total number of people who like comedy)
P(A|B) = 8 / 15
To express this as a percentage, multiply by 100:
P(A|B) * 100 ≈ 0.5333
Rounded to the nearest hundredth, the probability is 0.53 or 53%.

The graph represents function 1 and the equation represents function 2:
Function 2
y = 3x + 1
How much more is the rate of change of function 2 than the rate of change of function 1?
1
2
3
4
The rate of change of function 2 is 3 times greater than the rate of change of function 1.
Explanation:The rate of change of a function measures how much the output of the function changes when the input changes by 1 unit. In function 1, since the graph is a straight line, the rate of change is constant. We can find the rate of change of function 1 by finding the slope of the line, which represents the rate of change. In function 2, the equation is y = 3x + 1, so the rate of change is 3. Therefore, the rate of change of function 2 is 3 times greater than the rate of change of function 1.

8x^3 is common in the numerator, and on taking it out, we will get

How can x2 = x2 + 2x + 9 be set up as a system of equations?
Final answer:
To set up x^2 = x^2 + 2x + 9 as a system of equations, we would have x^2 = x^2 + 2x + 9 and x = -4.5.
Explanation:
To set up x2 = x2 + 2x + 9 as a system of equations, we can separate it into two separate equations:
Equation 1: x2 = x2 + 2x + 9
Equation 2: 0 = 2x + 9
By rearranging Equation 2, we can rewrite it as:
x = -4.5
Therefore, the system of equations for x2 = x2 + 2x + 9 is: x2 = x2 + 2x + 9 and x = -4.5.

There are 26.2 in a marathon .Write the number of miles using a fraction.
What is the slope of the line shown below?
Answer:
correct option is B) 2
Step-by-step explanation:
Slope of line is calculated by formula :-
Suppose two points on line are [tex](x_1, y_1) and (x_2 ,y_2)[/tex] then slope 'm' is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
We can see two points on line of graph are :- (-1, -4) and (2,2)
then slope will be calculated as,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
since [tex]x_1 = -1, x_2 =2, y_1=-4\;and\; y_2=2[/tex]
now, put in formula
[tex]m=\frac{2-(-4)}{2-(-1)}[/tex]
[tex]m=\frac{2+4}{2+1}[/tex]
[tex]m=\frac{6}{3}[/tex]
[tex]m=2[/tex]
Hence, slope is 2 of the provided graph.
Therefore, correct option is B) 2

if two triangles share a common side what else must be true for the SAS triangle congruence theorem to apply
The conditions to be added are:
The two triangles have congruent angles between the sides that are not the common side.
The two triangles have congruent lengths for the sides adjacent to the congruent angles.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The SAS (Side-Angle-Side) triangle congruence theorem states that if two triangles have two sides and the included angle of one triangle is congruent to two sides and the included angle of the other triangle, then the two triangles are congruent.
Therefore, in addition to sharing a common side, the two triangles must have congruent angles between the sides that are not the common side. Specifically, the angle opposite the common side must be congruent in both triangles.
To summarize, for the SAS triangle congruence theorem to apply, the following conditions must be met:
The two triangles share a common side.
The two triangles have congruent angles between the sides that are not the common side.
The two triangles have congruent lengths for the sides adjacent to the congruent angles (the "included" side).
Thus,
The conditions to be added are:
The two triangles have congruent angles between the sides that are not the common side.
The two triangles have congruent lengths for the sides adjacent to the congruent angles.

The area of a certain rectangle is 288 yd2. the perimeter is 68 yd. what are the dimensions of the rectangle?
The dimensions of the rectangle are a length of 16 yds and a width of 18 yds.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
Given that the perimeter is 68 yd
We know that the perimeter of a rectangle is:
P = 2(L + W)
∴ P = 68
68 = 2(L + W)
68/2 = L + W
34 = L + W
34 - L = W ....(i)
The area of a rectangle is:
A = L × W ....(ii)
∴ A = 288
Substitute the value W = 34 - L in equation (ii), and solve for L
288 = L(34 - L)
288 = 34L - L²
L² - 34L + 288 = 0
(L - 16)(L - 18)
L - 16 = 0 and L - 18 = 0
L = 16 and L = 18
Take L = 16 and substitute the value in the equation (i)
So, W = 34 - 16 = 18
Therefore, the rectangle's length is 16 yds and its width is 18 yds.

Suppose you toss a coin 100 times and get 76 heads and 24 tails. based on these results, what is the probability that the next flip results in a head?
The probability that the next flip results in a head is 50% or 0.5.
We have,
Total number of coins tossed = 100
Number of heads outcome = 76
Number of tails outcome = 24
Now,
The probability of getting heads in the tossing of coins 100 times.
= 76/100
= 0.76
= 76%
Now,
Generally for an unbiased coin.
The probability of getting a head in tossing a coin is 50%.
So,
Based on the results of the first 100 coin tosses, even if the probability of getting a head is 76% the probability that the next flip results in a head is still 50%.
Thus,
The probability that the next flip results in a head is 50% or 0.5.
