A poll was conducted in states A, B, and C to determine which candidate voters would most likely vote for. The results are displayed in the table below:
What is P(conservative | State B)?
State A State B State C Total
Liberal 17 20 12 49
Conservative 23 15 13 51
Total 40 35 25 100
Answers
Answer:
15/35 = 3/7 = 0.428571
Explanation:
We are asked to find the probability that a given voter is conservative given they are in State B.
Going to the State B column, we see that there are 15 conservatives. This is out of a total of 35 voters in state B; this makes the probability 15/35.
Probability helps us to know the chances of an event occurring. The probability that a voter from State B is supporting Conservative is 0.4285.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
We're supposed to figure out how likely it is that a specific voter in State B is a conservative.
There are 15 conservatives in State B, according to the column. This is based on a total of 35 voters in state B, resulting in a 15/35 probability. Therefore,
P(conservative | State B) = 15/35 = 3/7 = 0.4285
Hence, the probability that a voter from State B is supporting Conservative is 0.4285.

John wants to buy a new game for his computer. He can save $12 a week if he mows his neighbor's lawn and $10 a week if he babysits his nephew. How many weeks will it take John to save enough money to buy the computer game?
A.
total amount John can save in 1 week
B.

C.
amount John earns per hour babysitting
Answers
The answer is B.
the cost of the game.
We need to know the cost of the game in order to find out how many weeks John has to save money. If we don't know this price, we'll never know whether John has saved enough money.
We can find out the total amount of money John can save in 1 week (so A. is not the answer). The amount of money John earns per hour doesn't matter to answer the question (so C. is wrong).

We have,
To calculate Henry's annual retirement benefit, we need to find 2.5% of his average salary over the last five years.
First, let's calculate 2.5% of $95,000:
2.5% = 2.5/100 = 0.025
Annual benefit = 0.025 * $95,000
Annual benefit = $2,375
Therefore,

Which expression is equivalent to 4 sqrt 16x^11y^8/81x^7y^6
Answers
The given expression 4 sqrt(16x^11y^8/81x^7y^6) simplifies to (4/9) * x^2 * y by taking the square root of each term separately and then simplifying the powers of x and y.
Explanation:The expression given is 4 sqrt(16x^11y^8/81x^7y^6). To simplify this expression, we need to apply the square root to both the numerator and the denominator separately and simplify any like terms, as well as using the property of exponents to simplify the powers of x and y.
We start by simplifying the square root of each component:
Square root of 16 is 4.x^11 under the square root becomes x^(11/2).Similarly, y^8 under the square root becomes y^(8/2), which is y^4.The square root of 81 is 9.x^7 under the square root becomes x^(7/2).y^6 under the square root becomes y^(6/2), which is y^3.Now, divide and simplify:
(4 * x^(11/2) * y^4) / (9 * x^(7/2) * y^3) = (4/9) * x^((11/2) - (7/2)) * y^(4 - 3)
Therefore, we get:
(4/9) * x^2 * y

Answers
Applying Pythagorean Identity, the original equation sin² theta +cos theta = 2 can be altered by substituting sin² theta with 1 - cos² theta. This forms a quadratic equation: cos² theta - cos theta - 1 = 0, which can be solved using the quadratic formula to find the possible values of cos theta.
Explanation:To solve the equation sin² theta +cos theta = 2 by using the Pythagorean identity sin² theta +cos² theta =1, we can substitute sin² theta in the original equation with 1 - cos² theta.
Step-by-step solution:
We start by replacing sin² theta in the equation with 1 - cos² theta. So, the equation becomes 1 - cos² theta + cos theta - 2 = 0.This can be rearranged to form a quadratic equation as cos² theta - cos theta - 1 = 0.We can solve this quadratic equation using the quadratic formula cos theta = [- (-1) ± √{(-1)²-4(1)(-1)} ] /2(1).Computing the values, we get the two possible values of cos theta.Learn more about Pythagorean Identity here:https://brainly.com/question/24287773

The probability of event A is .43, the probability of event B is .32, and the probability of event C is .66. What is the probability of all three events occurring at the same time?
Answers
= 0.43*0.32*0.66 = 0.0908 Answer
Final answer:
The probability of independent events A, B, and C all occurring together is found by multiplying their individual probabilities: P(A AND B AND C) = P(A) × P(B) × P(C) = 0.090528.
Explanation:
The question involves calculating the probability of all three independent events happening simultaneously. To find the combined probability of independent events A, B, and C occurring at the same time, we use the multiplication rule of probability.
This rule states that if the events are independent, the probability of all events occurring is the product of their individual probabilities.
Here are the probabilities for each event:
Probability of event A (P(A)) = 0.43
Probability of event B (P(B)) = 0.32
Probability of event C (P(C)) = 0.66
The probability of events A, B, and C all occurring together is:
P(A AND B AND C) = P(A) × P(B) × P(C) = (0.43) × (0.32) × (0.66) = 0.090528

Answers
The correct linear system for the student's question is D. x + 3y \<= 38, x + y \<= 12, which matches the conditions of Lewis's situation for acquiring baseball cards.
The student is looking to match a situation with a linear system. The situation is that Lewis wants at most 12 packages of baseball cards, some containing 4 rookie cards and others 3 rookie cards, with a total of 38 rookie cards at most.
To match the situation with the correct linear system, we must set up two inequalities: one for the number of packages and another for the number of rookie cards.
Let x represent the number of packages with 4 rookie cards and y represent the number of packages with 3 rookie cards.
The first condition is that Lewis can have at most 12 packages, which gives us the inequality x + y \<= 12. The second condition is that the total number of rookie cards is at most 38, which gives us the inequality 4x + 3y \<= 38.
Considering these conditions, the correct answer is: D. x + 3y \<= 38, x + y \<= 12.
A trapezoid with an area of 166.75 in has bases that measure 21 in and 8 in find the height of the trapezoid
Answers
The required height of the trapezoid is 11.5 inches.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
The formula for the area of a trapezoid is:
A = (b₁ + b₂) * h / 2
where A is the area, b1 and b2 are the lengths of the two bases, and h is the height.
We are given that the area of the trapezoid is 166.75 in² and the lengths of the two bases are 21 in and 8 in. So we can plug these values into the formula and solve for h:
166.75 = (21 + 8) * h / 2
Simplifying the expression on the right side:
166.75 = 29 * h / 2
Multiplying both sides by 2:
333.5 = 29 * h
Dividing both sides by 29:
h = 11.5
So the height of the trapezoid is 11.5 inches.

Final answer:
To find the height of a trapezoid given its area (166.75 sq in) and bases (21 in and 8 in), you use the formula-
[tex]A = \frac{1}{2} h(b_1 + b_2)[/tex]
By rearranging to solve for h, you find that the height is 11.5 inches.
Explanation:
The question asks to find the height of a trapezoid given its area and bases. The area of a trapezoid is calculated using the formula A = [tex]\(\frac{1}{2}\)h(b_1 + b_2)[/tex], where A represents the area, h the height, and [tex]b_1[/tex] and [tex]b_2[/tex] the lengths of the two bases. In this case, the area is 166.75 square inches, and the bases measure 21 inches and 8 inches.
To find the height, we can rearrange the formula to-
h = [tex]\(\frac{2A}{b1 + b2}\)[/tex]
Plugging in the given values gives us-
h = [tex]\(\frac{2 \times 166.75}{21 + 8}\)[/tex]
which simplifies to-
h = [tex]\(\frac{333.5}{29}\)[/tex]
Therefore, the height of the trapezoid is 11.5 inches.

Answer:
Lateral area=100 square inches
Step-by-step explanation:
It is given that the perimeter of the base of a pentagonal prism is 25 inches, therefore each sides of the pentagon will be of 5 inches.
Also, one of its lateral edge is 4 inches, therefore each lateral face has area which will be equal to=[tex]5{\times}4[/tex]=[tex]20[/tex]square inches.
Since, there are 5 lateral faces of the pentagonal prism, therefore the lateral area of the prism will be: [tex]5{\times}20[/tex]
