The independent variable is h (the number of hours Neil works) and the dependent variable is B (the amount of Neil's bonus).
In this scenario, the amount of Neil's bonus (B) is dependent on the number of hours he works (h). The number of hours he works is the input or independent variable, while the amount of bonus he receives is the output or dependent variable. It can be said that the number of hours he works is the cause and the amount of bonus is the effect.
The equation is B = f(h) where f is the function that relates the two variables.
Thus, the independent variable is h (the number of hours Neil works) and the dependent variable is B (the amount of Neil's bonus).

A student researcher compares the ages of cars owned by students and cars owned by faculty at a local state college. A sample of 224 cars owned by students had an average age of 5.06 years. A sample of 233 cars owned by faculty had an average age of 7.19 years. Assume that the population standard deviation for cars owned by students is 3.42 years, while the population standard deviation for cars owned by faculty is 2.81 years. Determine the 95% confidence interval for the difference between the true mean ages for cars owned by students and faculty. Step 2 of 3 : Calculate the margin of error of a confidence interval for the difference between the two population means. Round your answer to six decimal places.
The difference between the population means - 3.4 and -1.84 when calculated is found to be -2.62 years.
The 95% confidence interval for the difference in true mean ages of cars owned by students and faculty is between -3.4 and -1.84 years.
We know that the sample of 138 cars which belongs to the students have an average age of 5.13 years. The standard deviation = 3.45 years.
Then again,
A sample of 111 cars which belongs to the faculty have an average age of 7.75 years. The standard deviation= 2.08 years.
So the difference between them will be , s - f
= 3.45 - 2.08 = 1. 37
and the mean will be , mean of students - mean of faculty =
-2.62.
This is the point of difference between their means.
The SD is found to be as 0.3961.
and MOE is 0.78
with these details now we will calculate the required intervals,
The lower end is found to be as -2.62 - 0.78 = -3.4
The upper end is found to be as -2.62 + 0.78 = -1.84
Therefore, the mean difference between the cars is - 3.4 and -1.84.

10) You use a technical support company for your computer. The company bills you at a rate of $10 per month and $35 per hour for phone support.
a. Identify the fixed cost (the constant).
b. Identify the independent variable (x).
c. Identify the dependent variable (y).
d. Write an equation that describes the situation above.
e. If you were billed $97.50 for last month, how many hours of phone support did you need? Show all work.
Answer:
a) 10
b) Number of hours of phone support (per month).
c) Total bill (per month).
d) y = 35x + 10
e) 2.5 hours
Step-by-step explanation:
The company bills you at a rate of:
$10 per month$35 per hourPart aThe fixed cost (the constant) is the cost per month ⇒ $10.
Part bThe independent variable is the variable that is not affected by any other variables.
Therefore, the independent value (variable x) is the number of hours of phone support per month.
Part cA dependent variable is the variable that is affected by the other variable.
Therefore, the dependent value (variable y) is the total bill (in dollars) per month.
Part dThe equation that describes the given situation is:
[tex]y = 35x + 10[/tex]Part eTo calculate how many hours of phone support was needed for a bill of $97.50, substitute y = 97.5 into the equation from part d and solve for x.
[tex]\implies 35x+10=97.5[/tex]
[tex]\implies 35x+10-10=97.5-10[/tex]
[tex]\implies 35x=87.5[/tex]
[tex]\implies \dfrac{35x}{35}=\dfrac{87.5}{35}[/tex]
[tex]\implies x=2.5[/tex]
Therefore, 2.5 hours of phone support was needed last month.

How far from their destination will they be 3. 7 hours since entering the freeway?
How far from their destination were they 2. 3 hours since entering the freeway?
Please help quick
Distance between them and their destination after 3.7 hours since entering the freeway is 608 miles and the distance between them and their destination after 2.3 hours since entering the freeway is 692 miles.
We know that the relationship between speed, distance, and time is given as,
Speed = distance/time
Speed = 60 miles an hour
Time = 3 hours
We know that Don and Ana are travelling at a constant speed and they are travelling for 3 hours.
Distance = speed × time
Distance = 60 × 3
Distance = 180 miles
Thus, the distance travelled by them in 3 hours is 180 miles.
We know that Don and Ana are travelling on the freeway for the past 3 hours and they are still 650 miles away, therefore,
Total Distance from their destination
= Distance travelled by them in 3 hours + 650 miles
= 180 miles + 650 miles
= 830 miles
Thus, the distance travelled by then is 830 miles.
Now, the distance between them and their destination after 3.7 hours since entering the freeway,
Distance travelled by them = speed x 3.7 = 60 x 3.7 = 222 miles
Distance between them and the destination
= Total Distance from their destination - Distance travelled by them
= 830 miles - 222 miles
= 608 miles
Therefore, they are 608 miles far from their destination.
And, Distance between them and their destination after 2.3 hours since entering the freeway,
Distance travelled by them = speed x 2.3 = 60 x 2.3 = 138 miles
Distance between them and the destination
= Total Distance from their destination - Distance travelled by them
= 830 miles - 138 miles
= 692 miles

What is a function?
A function is a mathematical relation between a set of inputs (called the domain) and a set of possible outputs (called the range). The inputs are usually denoted by variables and the outputs are usually denoted by the value of a function. A function assigns exactly one output to each input.
In the given problem, g(z) = 400z - z^2 is a function that describes the area of a field in square feet, where z represents the width of the field in feet.
Given that the width of the field is 50 feet, we can substitute this value into the function to find the area of the field:
g(50) = 400(50) - 50^2 = 20,000 - 2,500 = 17,500 square feet
We know that the farmer will plant spinach in this field and expect to harvest 1 pound of spinach per square foot. Therefore, the total number of pounds of spinach the farmer should expect to harvest from the field is:
1 pound/square foot * 17,500 square feet = 17,500 pounds

How to find the height of an isosceles triangle when only base is given?
It is not possible to find the height of an isosceles triangle when only the base is given. To find the height, you would need to know at least one other side length, in addition to the base.
The height of an isosceles triangle can be found using the Pythagorean Theorem, which states that the square of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the two shorter sides. To use the Pythagorean Theorem, you must first know the length of at least two sides of the triangle. Since only the base is given, it is not possible to calculate the height of the isosceles triangle. In order to find the height, you would need to know either the length of the other two sides, or the angle of one of the two equal sides. Once you have this information, you can use the Pythagorean Theorem to calculate the height of the triangle.

It takes 52 yards of fabric to make 8 costumes for the dance recital. How many yards are needed to make one costume?
Make a Ratio Table
(MUST INCLUDE THE TABLE!!)
Total 6.5 yards , fabaric are needed to make one costume for the dance recital.
We have , Total lengths of fabaric present for making costumes = 52 yards
Total number of costumes for the dance recital made from 52 yards = 8
we have to calculate the length of fabaric in yards are used for make one constume .
Let the " x yards " be the fabric length used to make one constume.
Now, total fabric length used to make 8 conatumes = 8x yards
but it will be equals to 52 yards . So, we get a simple linear equation with one variable, i.e
=> 8x = 52
=> x = 52/8
=> x = 6.5
So, the required fabric length is 6.5 yards .

What are absolute values?The distance of a number from a number line's origin is referred to as the absolute value of that number. Its representation is |x|, which establishes the size of any integer 'x'.
Any integer's absolute value, regardless of its sign, will be one of the real numbers, whether it is positive or negative. The modulus of x, which is represented by two vertical lines |x|, is a mathematical concept.
Without taking direction into account, absolute value describes how far away from zero a certain number is on the number line. A number can never have a negative absolute value.
Since absolute value can be zero the range is all positive numbers
