The 95% confidence interval for the mean daily income of a parking garage is between $5123.48 and $5134.52, indicating that the average daily income will be within this range.
What is mean?Mean is a form of average that is calculated by adding all of the numbers in a set and then dividing the total number of numbers in the set by the total number of numbers in the set. It is sometimes referred to as the arithmetic average.
Assuming the assumptions given in section a) are correct, the 95% confidence interval for the mean daily income generated by this parking garage may be computed using the method for calculating the confidence interval for a population mean. This confidence interval is computed by taking the sample mean, 5129, and multiplying it by 1.96 times the standard error of the mean, which is the standard deviation divided by the square root of the sample size. As a result, the 95% confidence interval is (5123.48, 5134.52).
This 95% confidence range implies that we can be 95% certain that the average daily income generated by this parking garage will be between $5123.48 and $5134.52. To put it another way, we may be 95% positive that the average daily income in this parking garage is generated.

The difference in length between the two rows is 3 units.
What exactly is a fraction strip?Fraction strips are rectangular pieces (electronic or paper) that represent distinct sections of the same whole. They may be taken apart and manipulated to demonstrate how different portions can be combined to produce the whole or to compare different fractional quantities for equivalence.
Let's assume that each fraction strip has a length of 1 unit. If Kendall puts four 1-unit fraction strips in one row, then the total length of that row would be 4 units. If Kendall puts one 1-unit fraction strip in the row below it, then the total length of that row would be 1 unit.
The difference in length between these two rows would be the length of the top row minus the length of the bottom row. Substituting the values we found, we get:
4 units - 1 unit = 3 units
Therefore, the difference in length between the two rows is 3 units.

ABCD is a rectangle.
B, E and C are points on the straight line P with the equation x+2y=10
This is about slope intercept form of equation. y = 3x + 66
How to find the equation?We are told that the equation of the straight line L is x + 3y = 18
Now, from the attached image, we can see that the line crosses the x axis at point B and the y axis at point E. These points are known as intercepts.
The x-intercept is when y = 0 while the y intercept is when x = 0. Thus;
x-intercept;
x + 3(0) = 18
x = 18
y-intercept;
0 + 3y = 18
3y = 18
y = 18/3
y = 6
This means we have two coordinates now which are;
B(18, 0) and E(0, 6)
We are told that AE = EB
From midpoint formula between two points, we can say that coordinate of point E is; (x + 18)/2 , (y + 0)/2
where x and y are coordinates of point A.
Thus; (x + 18)/2 = 0
x + 18 = 0
x = -18
Also, (y + 0)/2 = 6
y + 0 = 6 × 2
y = 12
The coordinates of point A are (-18, 6)
The equation of a line in slope intercept form is; y = mx + c
Thus; x + 3y = 18 gives; y = -(1/3)x + 18
where -1/3 is the slope
Line M passes through A and perpendicular to line L. Thus slope of line M = -1/(-1/3) = 3
Equation of Line M is; y - 12 = 3(x - (-18))
⇒ y - 12 = 3x + 54
⇒ y = 3x + 66

A group of 3 adults and 10 children bought tickets to watch a dance performance. Each adult ticket cost $7 more than each child ticket. The group paid a total of $125. What was the cost of each child ticket?
Answer:
Step-by-step explanation:
So 3a + 10c = 125 is translation of first sentence. Second part says a = c+7, "more than" indicating addition.
Substitute the 1st equation's a with c+7
So 3(c+7) + 10c = 125
Distribute.*+
3c + 21 +10c = 125
*Remember that 3(c+7) means to add up
c+ 7
c + 7
c + 7
‐-----------------
3c + 21
Combine 3c + 10c as 13c
So 13c + 21 = 125. Subtract 21 on each side (always treat left and right sides equally, believe in equality for all!!)
13c = 104. Divide each side by 13 (opposite of x)
c = 8........this is cost of each children's ticket
($8). Check: adult ticket is c +7 or $15. Does 3 adult tickets x $15 + 10 child tickets × 8 = 125? 45. + 80 = 125
Ssolution is correct. Can also be graphically to see where 3x + 10y = 125 crosses line x = y + 7

Answer:
18a²b²c²12x³y²z²Step-by-step explanation:
You want the least common multiple (LCM) of {6a²b, 9b²c, 3c²a} and of {4x²y²z², 6x³yz, 12xy²z}.
Least common multipleThe LCM of two or more terms is a product that has includes all of the factors of each of the terms. One way to find the LCM is to list the factors of the terms, identify the different ones and the powers of each, then choose the highest power of each of the different factors.
{6a²b, 9b²c, 3c²a}6a²b — factors are ...
23a²b9b²c — factors are ...
3²b²c3c²a — factors are ...
3ac²The distinct factors are ...
2 — power of 1; 1 is the highest power3 — powers of 1 and 2; 2 is the highest powera — powers of 1 and 2; 2 is the highest powerb — powers of 1 and 2; 2 is the highest powerc — powers of 1 and 2; 2 is the highest powerThe product of highest powers is the LCM:
LCM = 2¹·3²·a²·b²·c² = 18a²b²c²
{4x²y²z², 6x³yz, 12xy²z}
The distinct factors are ...
2 — powers of 1 and 2; 2 is the highest power3 — power of 1; 1 is the highest powerx — powers of 1, 2, and 3; 3 is the highest powery — powers of 1 and 2; 2 is the highest powerz — powers of 1 and 2; 2 is the highest powerThe product of the highest powers is ...
LCM = 2²·3¹·x³·y²·z² = 12x³y²z²
__
Additional comment
Sometimes the process of finding the LCM can be confused with finding the GCF (greatest common factor). The GCF will be the product of the lowest of the powers of the distinct factors. That power may be zero for any given factor in any given term.
For example, in the first set of terms, the factor 2 has a power of 0 in the last two terms. The factor 'a' has a power of zero in the second term; b has a power of 0 in the third term; c has a power of 0 in the first term. Then the GCF is ...
2⁰·3¹·a⁰·b⁰·c⁰ = 3 . . . . . GCF of {6a²b, 9b²c, 3c²a}
In the second set of terms, 2 has a power of 1 in the 2nd term; 3 has a power of 0 in the 1st term; x, y, z all have powers of 1 in at least one of the terms. Then the GCF is ...
2¹·3⁰·x¹·y¹·z¹ = 2xyz . . . . . GCF of {4x²y²z², 6x³yz, 12xy²z}
In short, every term must be a factor of the LCM, and the GCF must be a factor of every term.
One way to find the LCM of two terms is to divide their product by their GCF. The process can be repeated to include more terms in the LCM.

Which term is missing when using the square root method
The missing term when using the square root method is the discriminant. The discriminant is a number that is calculated from the coefficients of a quadratic equation.
What is quadratic equation?A quadratic equation is a type of mathematical equation that can be written in the form of ax² + bx + c = 0, where a, b, and c are real numbers, a cannot equal 0. It is called a quadratic equation because it has a second-order term, which is the x² term. This type of equation has two solutions, which are referred to as the roots. These roots can be found by using the quadratic formula, which is x = -b ± √(b² - 4ac) / 2a. This equation can be used to solve a wide variety of problems, including finding the length of a side in a right triangle, calculating the area of a circle, finding the maximum or minimum of a function, and solving systems of linear equations.

Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. EP) .79 (to 2 decimals) op .0288 (to 4 decimals)
The sampling distribution of p is 0.0288 (to 4 decimals).
The sampling distribution of p is a theoretical distribution of the proportion of successes (p) in a sample of a given size, drawn from a population with a known proportion of successes (p). In this case, the proportion of successes is the proportion of complaints involving new car dealers that are resolved, which is given as 0.79 (to 2 decimals).
The standard error of the proportion is given by the formula:
[tex]SE = \sqrt{(p * (1 - p) / n)}[/tex]
where n is the sample size. Plugging in the values, we get:
[tex]SE = \sqrt{(0.79 * (1 - 0.79) / 200)}[/tex] = 0.0288 (to 4 decimals).

Pedro earns $94.50 for 6 hours of work. If he makes a constant hourly wage, which table represents the relationship between the number of hours he works and his total earnings?
please help me
Answer:
The answer is most likely A.
The reason why, is because since the earning in 6 hours is $94.50, so the hourly wage would be, $15.75 because:
94.50/6 = 15.75
Graph B, for the first hour, the amount of dollars is correct, but in 11 hours, it says 25.75, which is not correct so Graph B cannot be it.
Graph C, shows that at hour 1, that it is 15.75 dollars, but at hour 2 16.75, as well with hour 3, 17.75. The graph is showing an increase of 1 dollar per hour, which is not correct so graph C is not it.
Graph D shows that at hour 6, there is $94.50, which is correct, but at hour 12, its 100.50. This is not true because , the hour has increased by 6, and when it increased by 6, the amount of pay increased by 6 as well, which is not the right way in which you would do so.
Option A is correct!
