What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the cost of one game ticket and y be the cost of one ride ticket.
From the table, we can form two linear equations regarding the total amount spent by Erica and Penny.
10x + 5y = 10
15x + 10y = 16.25
Multiplying the first equation throughout with 2,
20x + 10y = 20
Subtracting 15x + 10y = 16.25 from the above equation,
(20x + 10y) - (15x + 10y) = 20 - 16.25
5x = 3.75
x = 0.75
Substituting x = 0.75 in 10x + 5y = 10,
7.5 + 5y = 10
5y = 2.5
y = 0.5
Cost of a game ticket is $0.75 and cost of a ride ticket is $0.50.
Total cost by Edgar = (12 × 0.75) + (12 × 0.5) = $15
Hence the total money spent by Edgar for both game and ride tickets is $15.

What is the linear equations?
A linear equation is a mathematical equation that represents a straight line when graphed on a coordinate plane. It has the form of ax + b = y, where a and b are constants and x and y are variables. The coefficient "a" determines the slope of the line, and the constant "b" determines the y-intercept.
The elimination method is a method of solving a system of linear equations by adding or subtracting the equations to eliminate one of the variables.
Here is the solution for the system of equations 2x - 2y = 2 and 5x + 2y = 12 using the elimination method:
Multiply the first equation by 5: 10x - 10y = 10
Add the two equations: 15x - 8y = 22
Solve for x by dividing both sides of the equation by 15: x = 22/15 = 11/5
Substitute the value of x back into one of the original equations to solve for y:
2x - 2y = 2
2(11/5) - 2y = 2
22/5 - 2y = 2
22/5 - 2y = 2
22/5 = 2 + 2y
22/5 - 2 = 2y
20/5 = 2y
10/5 = y
The solution to the system of equations is (x, y) = (11/5, 10/5) = (11/5, 2).

Round your final

The probability that the mean of a sample of 40 families will be between 17.1 and 18.1 pounds is given as follows:
0.5874 = 58.74%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule 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, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 17.2, \sigma = 2.5, n = 40, s = \frac{2.5}{\sqrt{40}} = 0.3953[/tex]
The probability that the mean of a sample of 40 families will be between 17.1 and 18.1 pounds is the p-value of Z when X = 18.1 subtracted by the p-value of Z when X = 17.1, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (18.1 - 17.2)/0.3953
Z = 2.28
Z = 2.28 has a p-value of 0.9887.
Z = (17.1 - 17.2)/0.3953
Z = -0.25
Z = -0.25 has a p-value of 0.4013.
Hence:
0.9887 - 0.4013 = 0.5874 = 58.74%.

Answers
The total value of the nickels is 0.05n, and the total value of the dimes is 0.10(n + 5).
We know the total value of the coins is $1.70, so we can set up the following equation:
0.05n + 0.10(n + 5) = 1.70
Expanding the expression for the dimes:
0.05n + 0.10n + 0.50 = 1.70
Combining like terms:
0.15n + 0.50 = 1.70
Subtracting 0.50 from both sides:
0.15n = 1.20
Dividing both sides by 0.15:
n = 8

What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
Given that,
Principal amount, P = $3000
Rate of interest, r = 7% = 0.07
Number of years, n = 25
The final amount in a compound interest where the interest is compounded annually is,
A = P (1 + r)ⁿ
Substituting the given values,
A = 3000 (1 + 0.07)²⁵
= 3000 (1.07)²⁵

What is proportionality?the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given, Yuki and Roman are photographers for the yearbook. Yuki starts with 20 photos. She then takes 60 photos each week. Roman starts with 110 photos. He then takes 35 photos each week.
Let "w" the number of weeks they collected the pictures
For Yuki,
The total picture he has after 0 weeks = is 20
The total picture he has after 1 week = 20 + 60
The total picture he has after 2 weeks = 20 + 60*2
The total picture he has after w weeks = 20 + 60*w
For Roman,
The total picture he has after 0 weeks = is 110
The total picture he has after 1 week = 110 + 35
The total picture he has after 2 weeks =110 + 35*2
The total picture he has after w weeks = 110 + 35*w
To calculate the number of weeks when they have equals pictures:
20 + 60*w = 110 + 35*w
25w = 90
w = 3 3/5
Therefore, After 3 3/5 weeks, they will have the same number of pictures.

Answer:
1) 9
2) 27
3) Read explanation below!
Step-by-step explanation:
1) Use the Pythagorean theorem to find AD. Show your working
Pythagorean theorem = a²+b²=c²Where a = 12 and c=15 = 12²+?²=15²To find '?' we first have to expand the indices...
12² = 14415² = 225144 + ?² = 225Now work out '?'
225 - 144 = 81√81 = 92) Find AC. Show your working
We have found out that AD is 9 and to find AC we have to add 18!
9 + 18 = 273) Is ΔABC a right triangle? Explain
We can that ΔABC is not a right angle as none of the angles in the triangle are 90°! If it was a right angled triangle we would see the ∟sign on one of the angles. Even though there are two of those in the middle it does not count as the question is asking about ΔABC!!

With one method of a procedure called acceptance sampling, a sample of items is randomly selected without
replacement and the entire batch is accepted if every item in the sample is okay. The ABC Electronics
Company has just manufactured 1650 write-rewrite CDs, and 60 are defective. If 3 of these CDs are randomly
selected for testing, what is the probability that the entire batch will be accepted?
Rounded to four decimal place accuracy.

Therefore , the solution of the given problem of probability comes out to be likelihood that the full batch will be approved is therefore 0.832.
What does the probability procedure entail in detail?Probability theory is an area of mathematics that focuses on calculating the probability that a claim is accurate or that a particular occurrence will occur. Chance can be represented by any number range between 0 and 1, where 1 often denotes certainty and 0 typically denotes possibility. A probability diagram shows the possibility that a specific event will occur. The numerals 0 and 1, fractions with a ranging of 0% to 100%, or a few more characters can all be used to indicate probabilities.
Here,
Given that we've done it
Amount of CDs: 2100
50 faulty CDs total.
If every component of the sample is acceptable, the complete batch is accepted.
Therefore, we shall apply the "Binomial Theorem"
If there is no flaw, let p be the likelihood of success.
So, => p = 2100 - 50 / 2100
=> p = 2050/2100
=> p =0.97
q is the likelihood of a failure, or defect.
So,
=> q = 50/2100
=> q = 0.02
hence, the number of CDs chosen is 6.
Consequently, it is => P(X=6) = (0.97)6 = 0.832.
The likelihood that the full batch will be approved is therefore 0.832.

Given the following composite figures, d=8.6 cm and w=12.5 cm. What is the perimeter of the figure?
Answers
a. The perimeter of the figure is: 61.4 cm
b. The area of the figure is: 160.69 cm²
How to Find the Perimeter and Area of a Figure?The figure consists of two semicircles which makes one full circle and a rectangle. Therefore:
a. The perimeter of the given figure = circumference of a circle + 2w.
d = 8.6 cm
Circumference of the circle = 2 * pi * r = 2 * 3.14 * (8.6/2) = 27.00 cm
Perimeter = 27.00 + 2(17.2)
Perimeter = 61.4 cm
b. Area = area of circle + area of rectangle = 2πr + (length * width)
r = 7.9/2 = 3.95 cm
length = w = 17.2 cm
width = d = 7.9 cm
Area = 2*3.14*3.95 + (17.2*7.9) = 160.69 cm²
