The expected value of the game is $16.50.
How to find the expected value of the game?First we need to multiply the amount you can win by the probability of winning it, then add up all the products.
Let's call the expected value "E":
E = (0.20 x $60) + (0.15 x $30) + (0.25 x $0) + (0.40 x $0)
E = $12 + $4.50 + $0 + $0
E = $16.50
Therefore, the expected value of the game is $16.50.

JH is the geometric mean of which two segments?
Answer:
J is 90° while H is 180°
Answer the questions below.
(a) From the 12 albums released by a musician, the recording company wishes to release 9 in a boxed set. How many different boxed sets are possible?
(b) There are 14 European cities that Rashid would eventually like to visit. On his next vacation, though, he only has time to visit 3 of the cities: one on Monday, one on Tuesday, and one on Wednesday. He is now trying to make a schedule of which city he'll visit on which day. How many different schedules are possible? (Assume that he will not visit a city more than once.)
(a) There are 220 different boxed sets possible.
(b) here are 2184 different schedules possible for Rashid's vacation.
(a)
To calculate the number of different boxed sets possible, use the combination formula. In this case, choose 9 albums out of 12, and the order of the albums in the boxed set doesn't matter.
The number of combinations of n items taken r at a time is given by the formula:
C(n, r) = n! / (r! × (n - r)!)
In this case, to find C(12, 9):
C(12, 9) = 12! / (9! × (12 - 9)!)
C(12, 9) = 12! / (9! × 3!)
C(12, 9) = (12 × 11 × 10) / (3 × 2 × 1)
C(12, 9) = 220
(b)
To calculate the number of different schedules Rashid can make for his vacation, count the number of ways chosen 3 cities out of 14 for each day of the week.
For Monday, choose one city out of 14.
For Tuesday, choose one city out of the remaining 13 .
For Wednesday, choose one city out of the remaining 12 .
Total number of schedules = 14 × 13 × 12 = 2184
So, there are 220 different boxed sets possible and there are 2184 different schedules possible for Rashid's vacation.

Maria was paid $1854 for laying the Corbett's lawn. If she charged $135 plus 9.55 per square metre of lawn laid, find the area of the lawn.
Let's represent the area of the lawn with "x" (in square meters).
Maria charged $135 plus $9.55 per square meter, so her total earnings can be expressed as:
Total earnings = $135 + $9.55 x
We know that Maria was paid $1854, so we can set up an equation and solve for x:
$1854 = $135 + $9.55 x
Subtracting $135 from both sides:
$1719 = $9.55 x
Dividing both sides by $9.55:
x = 180
Therefore, the area of the lawn is 180 square meters.

How to convert 8 into cm
The value of length 8inch into cm is 20.32 cm.
8inch can be converted into centimeters (cm) using the conversion factor of 1 inch equals 2.54 centimeters. it's essential to use the appropriate conversion factor and ensure that the units cancel out correctly to arrive at the desired result.
Since 8 is a unit of inches, we can simply multiply 8 by the conversion factor of 2.54 cm/inch to get the equivalent measurement in centimeters.
So, the conversion can be done as follows:
8 inches x 2.54 cm/inch = 20.32 cm
Therefore, 8 inches is equal to 20.32 centimeters.

What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that;
You flip 3 coins 50 times.
And, Flipping 3 tails occurs 6 times and flipping 3 heads occurs 7 times.
Hence, The experimental probability that you flip 3 heads is,
⇒ 7 / 50
And, The experimental probability that you flip 3 tails is,
⇒ 6 / 50
And, Number of times to flip 3 tails out of 200 trials of flipping 3 coins is, x
Hence, We can formulate;
x = 3/25 × 200
x = 3 × 4
x = 12
Thus, There are 12 times to flip 3 tails out of 200 trials of flipping 3 coins.
Therefore, we get;
c) The experimental probability that you flip 3 heads is,
d) The experimental probability that you flip 3 tails is,

a small town in the UK has only 600 high school students. what is the largest possible sample you can take from this town and still be able to calculate the standard deviation of the sampling distribution of p-hat?
To calculate the standard deviation of the sampling distribution of p-hat, the answer will be 59 students.
By calculating,
600/10=60 and 59 students which is less than 10% of the population.
A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a given random-sample-based statistic. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.
Because they offer a significant simplification before drawing conclusions using statistics, sampling distributions are crucial in the field. They enable analytical decisions to be made based on the probability distribution of a statistic rather than the combined probability distribution of all the individual sample values

What is variance in statistics?
Variance in statistics is the squared difference between a random variable's expected value and its mean value.
Data points' variance from the mean is a measure of how they vary. A variance, according to Layman, is a measurement of how widely apart a set of data (numbers) are from their mean (average) value.
Finding the expected difference of deviation from the actual number is what is meant by variance. As a result, variance is influenced by the data set's standard deviation.
Data is more dispersed from its mean the higher the variance value, and less dispersed from mean if the variance value is low or minimal. As a result, it is referred to as a measure of data spread from mean.
