The probability of the coin being the weighted one given that it returned heads is 0.8.
P(Weighted | Heads) = ( P(Heads | Weighted) * P(Weighted) ) / P(Heads)
= ( 0.8 * 0.5 ) / 0.5
= 0.8
The probability of the coin being the weighted one given that it returned heads can be calculated using Baye's Theorem. This theorem states that the probability of an event given a condition is equal to the probability of the condition given the event multiplied by the probability of the event divided by the probability of the condition. In this case, the event is the coin being weighted, the condition is the coin returning heads. Therefore, the probability of the coin being the weighted one given that it returned heads is equal to the probability of the coin returning heads given that it is weighted multiplied by the probability of the coin being weighted divided by the probability of the coin returning heads. The probability of the coin returning heads given that it is weighted is 0.8, the probability of the coin being weighted is 0.5, and the probability of the coin returning heads is 0.5. Thus, the probability of the coin being the weighted one given that it returned heads is 0.8.

What algebraic expression could represent the average of 2x, 3 + x and 6x?
The algebraic expression in simplified form representing the average is 3x + 1.
To solve this question, one must know the formula of average. It is as follows -
Average = sum of the numbers / quantity of numbers
Now, we see that there are 3 expressions in the question. Hence, quantity of numbers will be 3.
Sum of the numbers = 2x + 3 + x + 6x
So, keep the values in formula to find the expression -
Average = 2x + 3 + x + 6x/ 3
Simplifying the expression to find average
Average = 9x + 3/3

At the start of a party, a drink dispenser contains 912 quarts of iced tea. After the party only 7 cups of tea remain. How many cups of iced tea did people drink during the party?
Amount of iced-tea consumed during party was 92 cups, which is equivalent to 23 quarts. It's important to note difference between volume units such as cups and quarts, and the conversion factor between them.
To determine the number of cups of iced-tea that were consumed during the party, we need to subtract the amount that remained from the total amount that was in the drink dispenser at the start of the party.
One cup of iced tea is equal to 1/16 of a quart, so 7 cups is equal to
7 * (1/16) = 7/16 quarts.
Thus, the total amount of iced tea that was consumed during the party is 912 quarts -
7/16 quarts = 912 - 7/16
= 912 - 7 * (1/16)
= (912 * 16 - 7 * 1) / 16
= 1476 / 16
= 92.25 cups, rounded down to the nearest whole number, which is 92 cups.
It is important to note that the answer is given in cups and not quarts. Quarts is a unit of volume and cups is a unit of volume as well, but they are not equivalent. 1 quart is equal to 4 cups. If we wanted to express the amount of iced tea consumed in quarts, we would multiply the answer by 1/4.
In conclusion, the number of cups of iced tea consumed during the party is 92 cups, and if we express this in quarts it is equivalent to
92 * (1/4) = 23 quarts.

The first day after the autumn equinox that the solar panel generates 8400 kJ is approximately 39.2 days, or 0.107 radians, after the equinox.
To find the first day after the autumn equinox that the solar panel generates 8400 kJ, we need to solve the equation:
624sin(2π/365)t + 8736 = 8400
Simplifying the equation, we get:
sin(2π/365)t = 0.958
Taking the inverse sine of both sides, we get:
(2π/365)t = 1.296 or (2π/365)t = 3.846
Solving for t in each equation, we get:
t ≈ 78.97 or t ≈ 235.62
Since t is measured in radians, we need to convert it to days by dividing by 2π/365:
t ≈ 78.97 / (2π/365) ≈ 86.75 or t ≈ 235.62 / (2π/365) ≈ 256.73
Therefore, the first day after the autumn equinox that the solar panel generates 8400 kJ is either day 87 or day 257.

Gina wilson all things algebra unit 4: congruent triangles homework 7: proofs review: all methods page 1
In geometry, two triangles are said to be congruent if they are the same size and shape. This means that all corresponding angles and sides are equal.
To prove that two triangles are congruent, we must use one of the five congruency tests: Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), and Hypotenuse-Leg (HL).The SSS test states that if all three sides of two triangles are equal, then the triangles are congruent. The SAS test states that if two sides and the included angle of two triangles are equal, then the triangles are congruent. The ASA test states that if two angles and the included side of two triangles are equal, then the triangles are congruent. The AAS test states that if two angles and a non-included side of two triangles are equal, then the triangles are congruent. Lastly, the HL test states that if the hypotenuse and a leg of a right triangle are equal to the hypotenuse and a leg of another right triangle, then the triangles are congruent.In order to prove that two triangles are congruent, we must show that one of the five congruency tests is true. To do this, we can use techniques such as the Reflexive Property, the Symmetric Property, and the Transitive Property. We can also use logical reasoning, such as if two angles are equal and their corresponding sides are proportional, then the triangles must be congruent.

Can someone explain this
Step-by-step explanation:
This is a family of curves represented by the equation:
y = a (x + 4) (x − 2)
Different values of the a coefficient result in different quadratic functions.
The vertex of the parabolas is halfway between the zeros, at x = -1.
y = a (-1 + 4) (-1 − 2)
y = -9a
So to find the value of a, divide the y-coordinate of the vertex by -9. For example, curve A has a vertex at (-1, -3), so the value of the a coefficient is -3 / -9 = ⅓.
A. y = ⅓ (x + 4) (x − 2)
B. y = (x + 4) (x − 2)

a gambler has a fair coin and a two-headed coin in his pocket. he selects one of the coins at random; when he flips it, it shows heads. what is the probability that it is the fair coin?
The probability of selecting the fair coin when a gambler has both a fair coin and a two-headed coin in his pocket is 50%.
This is because, when he selects one of the coins at random, it is equally likely that he has chosen either the fair coin or the two-headed coin. If he flips the coin and it shows heads, then the probability that it is the fair coin is still 50%, because either coin could have been selected and both would show heads.This is an example of a classical probability problem, which is based on the law of equal chances. This law states that when an event has multiple possible outcomes, each of those outcomes is equally likely to occur. In this case, there are two possible coins that could have been chosen, so each coin has a 50% chance of being selected. This means that the probability of selecting the fair coin is 50%.This also applies to events that have multiple outcomes which are not equally likely. For example, if a gambler has a fair coin, a two-headed coin, and a three-headed coin in his pocket, the probability of selecting the fair coin is still 50%. This is because the gambler has an equal chance of selecting any of the coins, regardless.

pounds of fruit to a fruit basket. Her son took 2 3/8 pounds
of fruit out of the basket. What was the total change in pounds of fruit in the

Answer: To find the total change in pounds of fruit in the basket, we need to subtract the amount taken out from the amount added.
First, let's convert all the fractions to decimals:
1 1/4 = 1.25
2 3/8 = 2.375
Now, we can subtract:
1.25 - 2.375 = -1.125
So, the total change in the fruit basket was -1.125 pounds, meaning the basket had 1.125 pounds less fruit after the removal.
