A child's ticket cost is $12.50 and an adult's ticket cost $25.00.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Mr and Mrs Tan and their three children bought tickets for a 'Holiday- On-Ice' show.
Let x be the cost of a child's ticket, 2x be the cost of adult's ticket
The cost of all three children's tickets would be 3x and total cost of Mr. and Mrs. Tan's tickets would be 4x
So the total cost of all five tickets would be 3x + 4x = 7x.
We know that the total cost was $87.50
7x = 87.50
Divide both sides by 7
x = 87.50 / 7
x=12.50
Hence, a child's ticket cost is $12.50 and an adult's ticket cost $25.00.

suppose that you are awarded prize money if you match at least three of the winning numbers. the probability that you will win some prize money is .
The frequency of winning numbers you can match, determines your chance of winning a prize.
The likelihood of earning some money is one if you can match three or more of the winning numbers (certain). However, the probability of winning any prizes is zero if you can only match two or fewer of the winning numbers (impossible).
Probability distribution: The probability that a random variable will take on a specific value or range of values is expressed mathematically as a probability distribution. It is often referred to as a probability mass function or a probability density function (PDF) (PMF). Each result of a random event, such as the roll of a dice, the toss of a coin, or a stock market return, is given a probability by the probability distribution.

if the variance of the population a is 10 and the variance of the population b is 15, does it mean that population a has less variability than population b?
Yes, the given statement is true if the variance of the population 'a' is smaller than the variance of population 'b' it represents that population 'b' is more variable than 'a'.
Population variance represents the measurement of spread of group data points.It shows the average squared deviation from the given mean.Whenever data points are very near to the mean then the variance has smaller value.And when data points are far away to the mean then it has larger value of variance.Here variance of population 'a' is 10 which is smaller than the variance of population 'b' .It represents population 'a' is less variable than population 'b'.Therefore, the given statement is true for the variance of population 'a' and 'b'.

jill is taking 5 courses (or 15 credit hours). how many hours of homework should she expect each week in addition to her time spent inside the classroom?
Jill should expect an additional 30 to 45 hours of homework each week.
As a general rule of thumb, students can expect to spend 2-3 hours of homework for each hour spent in class. This means that for a 15 credit hour course load, Jill can expect to spend an additional 30 to 45 hours on homework each week.
However, this is just a rough estimate and the actual amount of time required will depend on the difficulty of the courses, the teaching style of the instructors, and the individual study habits and ability of the student.

Two boats were 400 miles apart at midnight and were both sailing to the same port on Honolulu. One boat was heading west and the other was heading east. If they both arrived at 8:00am, find the speed of each boat if one was 20MPH faster than the other.
The speed of the air or water increases and its pressure decreases as it circles the longer-path side of the sail or keel. The air or water will attempt to migrate from the side of high pressure to the side of low pressure as it moves along the sail or keel in response to the consequent pressure difference.
How is sailing speed determined?Theoretical displacement hull speed is determined by the following equation: velocity in knots = 1.35 x waterline length in feet squared.
Use x to symbolise the slower boat's speed.
Therefore, the faster boat's speed would be x + 20 mph.
They met for 8 hours, hence the distance they travelled overall during that period is depicted as
Distance: (x + 20) * 8 + x * 8
Thus, we have
Distance: 16x plus 160
At twilight, the two boats were separated by 400 kilometres.
The distance equation is as follows.
400 = 16x + 160
Analyze similar terms
16x = 240
multiply by 16
x = 15
Remember that
20 mph faster boat equals x.
Thus, we have
Speedier boat = 15 plus 20
Speedier boat = 35

which measure of center can you most accurately estimate from this information: Median
The median divides the data into equal-sized groups. So approximately 50% of the data is above the median and approximately 50% of the data is below the median.
Calculating the median
The median is the value in a data set, implying that half of data focuses have a value more modest or equivalent to the median and half of data focuses have a value higher or equivalent to the median.
For a little data set, you first count the quantity of data focuses (n) and organize the data focuses in expanding request. Assuming the quantity of data focuses is lopsided, you add 1 to the quantity of places and separation the outcomes by 2 to get the rank of the data point whose value is the median.

A correlational result can be used to infer causality, but only if the value of r is greater than 0.
What is infer causality?In statistics, a correlation coefficient is a measure of the strength and direction of the linear relationship between two variables. A positive correlation coefficient implies that two variables are related (as one variable increases, so does the other), whereas a negative correlation value shows that two variables are inversely related (as one variable increases, the other decreases).A correlation value of zero shows that no relationship exists between two variables. However, a correlation coefficient greater than 0 does not imply causality, meaning that it cannot be concluded that one variable causes changes in the other variable. Establishing causality requires additional evidence and methods such as experimental designs or causal inference techniques.To learn more about infer causality refers to:

the average area of a bedroom in a home is 219 square feet with a standard deviation of 32.5 square feet. what is the largest a bedroom can be and be among the smallest 20% of bedrooms in a home?
The largest a bedroom can be and still be among the smallest 20% of bedrooms in a home is around 271 square feet.
To understand this answer, we have to use the concept of standard deviation, which is a measure of how spread out the data is from the mean. In this case, the average area of a bedroom is 219 square feet, with a standard deviation of 32.5 square feet. To calculate the 20th percentile, we need to find the value of X such that P(X < x) = 0.20, where P(X < x) is the cumulative distribution function of X.
We can use a standard normal table to find the Z-score corresponding to 0.20 and then convert it back to the original scale. The Z-score for 0.20 is -0.84. Therefore, x = 219 + 32.5 * (-0.84) = 271, which is the largest a bedroom can be and still be among the smallest 20% of bedrooms in a home.

What is the percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
Given that,
The total number of students who prefer tennis is 20.
And the total number who prefer football is 14,
so the total number who prefer either tennis or football is
⇒ 20 + 14
⇒ 34
To find the percentage of students who prefer either tennis or football, we can divide the number of students who prefer either by the total number of students and multiply by 100:
(34 / 250) x 100 = 13.6%
So, approximately 13.6% of the 8th grade class prefer either tennis or football.

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the distance of Main Street be D
Now , let the triangle be represented as ΔABC
The base of the triangle BC = 300 feet
The hypotenuse of the triangle AC = distance between First avenue and Canal street
The measure of angle ∠BAC = 70°
From the trigonometric relations , we get
sin θ = opposite / hypotenuse
Substituting the values in the equation , we get
sin 70° = 300 / D
Multiply by D on both sides of the equation , we get
D ( sin 70° ) = 300
Divide by sin 70° on both sides , we get
D = 300 / ( sin 70° )
On further simplification , we get
D = 300 / 0.939692
D = 319.2535
D = 319.25 feet
