The measure of the sides of the triangle is x = 15√3
Given data ,
We know that in the right triangle supplied, the bottom leg (adjacent side to the 30-degree angle) is "15" and the left leg (adjacent side to the 60-degree angle) is "x"
The ratio of the lengths of the side across from the angle and the side next to it is known as the tangent of an angle in a right triangle
From the trigonometric relations , we get
tan 60 = opposite side / adjacent side
tan(60°) = √3 = x/15
Multiply by 15 on both sides , we get
x = 15√3
Hence , the measure of side is x = 15√3

C) ΔFHG ≅ ΔPRQ by the AAS triangle congruence theorem----------------------
AAS congruence theorem states that:
If two angles and a non-included side of one triangle are congruent to two angles and a non-included side of another triangle, then the triangles are congruent.We can see two angles and the non-included side are marked as congruent:
∠R ≅ ∠H, ∠Q ≅ ∠G and PQ ≅ FG,Hence the triangles are congruent:
ΔFHG ≅ ΔPRQTherefore the correct choice is C.
4. Determine the z-score for each situation using a z-score table or a graphing calculator.
a:
35% of the data is to the left of the
Z-score.
b:
18% of the data is to the right of the
z-score.
The z-scores for each situation are given as follows:
a) 35% of the data is to the left: z = -0.385.
b) 18% of the data is to the right: z = 0.915.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.From the second bullet point, we have that the z-score for which 35% of the data is to the left of the Z-score is z with a p-value of z = 0.35, hence z = -0.385.
The z-score for which 18% of the data is to the right of the data-set, is z with a p-value of 1 - 0.18 = 0.18, hence it is z = 0.915.

The price of P , of a pizza varies directly as the square of its radius R. If a pizza with the diameter of 20cm cost $6.00 . What would a pizza with a radius of 12cm cost ?
Answer: $8.64.
Step-by-step explanation:
P = price of the pizza
R = radius of the pizza
We know that the price of the pizza varies directly as the square of its radius. This means that we can write the following equation:
P = kR^2
where k is a constant of proportionality.
We are given that a pizza with a diameter of 20 cm costs $6.00. This means that the radius of the pizza is 10 cm. We can use this information to find the value of k.
6 = k(10)^2
6 = 100k
k = 0.06
Now that we know the value of k, we can find the price of a pizza with a radius of 12 cm.
P = 0.06(12)^2
P = 0.06(144)
P = 8.64
Therefore, a pizza with a radius of 12 cm would cost $8.64.

a cab was involved in a hit-and-run accident at night. two cab companies green and blue operate 85% and 15% of the cabs in the city respectively. a witness identified the cab as blue. however, in a test only 80% of witnesses were able to correctly identify the cab color. given this what is the probability that the cab involved in the accident was blue?
From Bayes' Theorem, an event, the probability that the blue cab involved in accident as well as witness also identified it as blue cab is equals to the 0.41 or 41%.
Bayes' Theorem states that the conditional probability of an event, is based on the occurrence of another event, is equal to the like of the second event the first event multiplied by the probability of the first event. According to scenario, it is found that a cab was involved in a hit and run accident at night. Number of cab companies operates in city = 2 (blue and green)
Probability that green cab involved in accident, P(G) = 85% = 0.85
Probability that blue cab involved in accident, P(B) = 15% = 0.15
Now, the cab which is identified by witness was a blue cab. Here, probability that witness is correct to identification a blue cab = P(W/B) = 0.80
Probability that witness is wrong to identify the blue cab = P(W/G) = 0.20
Using the Baye's theorem, Probability that accident was caused by blue cab provided witness identifies is written as [tex]P(B/W) = \frac{ P(B ∩W) }{P(W)} = \frac{ P(B) P( W/B)}{W}[/tex]
Total Probability, [tex]P(W) = \frac{P(B)}{P(W/B)}+ \frac{P(G)}{P(W/G)}[/tex]

Raashan, sylvia, and ted play the following game. each starts with $1. a bell rings every 15 seconds, at which time each of the players who currently have money simultaneously chooses one of the other two players independently and at random and gives $1 to that player. what is the probability that after the bell has rung 2019 times, each player will have $1? (a) 1 7 (b) 1 4 (c) 1 3 (d) 1 2 (e) 2
The probability that each player will have $1 after 2019 rings of the bell is: (c) 1/3.
To solve this problem, we need to think about the possible outcomes of the game. Each time the bell rings, each player has a 1/2 probability of giving $1 to one of the other two players. This means that after one ring of the bell, there are 2^3 = 8 possible outcomes, as each player can either give or not give money to each of the other players.
After two rings of the bell, there are 2^8 = 256 possible outcomes. After three rings, there are 2^12 = 4,096 possible outcomes. And so on.
To find the probability that after 2019 rings of the bell, each player will have $1, we need to find the total number of possible outcomes and the number of outcomes in which each player has $1.
The total number of possible outcomes after 2019 rings of the bell is 2^(3*2019) = 2^6057.
To count the number of outcomes in which each player has $1, we can use a combinatorial argument. We need to distribute 2019 dollars among the three players in such a way that each player ends up with exactly $1. This is equivalent to choosing two numbers between 0 and 2019, inclusive, and giving the first player the smaller amount, the second player the difference between the larger and smaller amounts, and the third player the remaining amount.
The number of ways to choose two numbers between 0 and 2019 is (2019+2) choose 2 = 2036 choose 2 = 2,066,530.
Therefore, the probability that each player will have $1 after 2019 rings of the bell is:
2,066,530 / 2^6057 = 1/3
So the answer is (c) 1/3.
In the game where Raashan, Sylvia, and Ted each start with $1 and a bell rings every 15 seconds, the probability that after the bell has rung 2019 times, each player will have $1 is (a) 1/7.

The perimeter of the cross-section of the rectangular prism is 42 meters.
The cross-section formed by the plane that contains points D, E, K, and L is a trapezoid with bases DE and KL and height 5.
The length of DE can be found using the Pythagorean theorem: DE = √((EK - DK)² + (EL - DL)²) = √((12 - 4)² + (0 - 0)²) = 8 meters.
Similarly, the length of KL is also 8 meters.
Therefore, the perimeter of the cross-section is the sum of the lengths of the sides of the trapezoid, which is given by
perimeter = DE + KL + 2√((EK - DL)² + 5²)
perimeter = 8 + 8 + 2√((12 - 0)² + 5²)

n a group of 50 people, what is the expected number of days of the year which are one of their birthdays?
Answer: there's a 50-50 chance of at least two people having the same birthday.
In a group of 50 people, the expected number of days of the year which are one of their birthdays can be determined using the concept of probability which are one of their birthdays is approximately 194 days.
The expected number of days of the year which are one of their birthdays in a group of 50 people can be calculated using the formula E(X) = np, where n is the number of trials and p is the probability of success in each trial. In this case, there are 50 people and 365 days in a year, so each person has a probability of 1/365 of having their birthday on a particular day. Therefore, the expected number of people with a birthday on any given day is 50*(1/365) = 0.137. Since there are 365 possible days, we can multiply this by 365 to get the expected number of days with at least one birthday, which is approximately 50.034 days. So, the expected number of days of the year which are one of their birthdays in a group of 50 people is around 50.034.
In a group of 50 people, the expected number of days of the year which are one of their birthdays can be determined using the concept of probability.
Assuming that each person's birthday is equally likely to fall on any of the 365 days in a year (ignoring leap years), the probability of any particular day being a birthday is 1/365.
Now, the probability of a day not being a birthday for a single person is (364/365). For 50 people, the probability of a day not being any of their birthdays would be (364/365)^50.
To find the expected number of days with at least one birthday, we can calculate the probability of a day having at least one birthday, which is the complement of no birthdays on that day. This probability is:
1 - (364/365)^50
Now, we multiply this probability by the total number of days in a year to find the expected number of days with at least one birthday:
365 * (1 - (364/365)^50) ≈ 194.03
So, in a group of 50 people, the expected number of days of the year which are one of their birthdays is approximately 194 days.

The volume of the prism is 792 cubic feet.
To find the volume of a rectangular prism, we need to multiply its length, width, and height.
The three-dimensional solid object known as a prism has identical ends and flat sides. The shape of its ends—a rectangular prism or a triangular prism—gives the object its name.
The volume of a prism may be estimated by dividing the area of the base by the height.
Given the dimensions of the prism:
Length = 9 ft
Width = 8 ft
Height = 11 ft
Volume = Length x Width x Height
Volume = 9 ft x 8 ft x 11 ft
Volume = 792 cubic feet

Total amount = $700 + $40m + $50(m-4)
Condensing the phrase:
Total amount = $700 + $40m + $50m - $200
Total amount = $90m + $500
Therefore, the simplified expression for the amount of money Troy received m months after his mother started giving him money is $90m + $500.

I need some help with this.
The mean of the data set A is 6.5
And the mean of the data set B is 3
We know that the mean of the data set is nothing but the ratio of the sum of all data values to the total number of data values in the data set.
From the attached line plot, the data values of data set A would be,
4, 5, 5, 5, 6, 6, 7, 7, 8, 8, 8, 9
Using above definition of mean, the mean of data set A would be,
m₁ = (4 + 5 + 5 + 5 + 6 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 12
m₁ = 78/12
m₁ = 6.5
And the data values of data set B would be,
1,2, 2, 2, 3, 3,3, 4, 4, 4, 5
m₂ = 1 + 2 + 2 + 2 + 3 + 3 + 3 + 4 + 4 + 4 + 5
m₂ = 33/11
m₂ = 3

if you go three times faster than another car, then how many times longer will it take for you to stop the car? how do you know this?
If you go three times faster than another car, it will take nine times longer to stop your car than the other car.
To understand why, we need to consider the physics of stopping a car. The distance required to stop a car depends on the car's speed and braking ability.
Assuming the braking ability is the same for both cars, we can use the equation:
distance = (speed)² / (2 * deceleration)
where deceleration is the rate at which the car slows down.
Since we are assuming that the other car and your car have the same deceleration, we can write:
distance other car = (speed other car)² / (2 * deceleration)distance your car = (speed your car)² / (2 * deceleration)We know that your car is going three times faster than the other car, so:
speed your car = 3 * speed other car
Substituting this into the equation for the distance of your car, we get:
distance your car = (3 * speed other car)²/ (2 * deceleration)
distance your car = 9 * (speed other car)² / (2 * deceleration)
Therefore, the distance required to stop your car is nine times greater than the distance required to stop the other car. Since the time to stop is directly proportional to the distance required to stop, it will also take nine times longer to stop your car than the other car.
