The slope of the line of best fit provides valuable information about the relationship between the two variables being plotted and can be used to make predictions about future data points or to identify patterns and trends in the data.

What is the slope?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

The slope of the line of best fit on a scatter plot represents the rate of change between the two variables being plotted.

In the case of Keilantra's math teacher, the slope of the line of best fit between student grades on weekly quizzes and the number of hours they say they study represents the change in grades for every additional hour of studying.

For example, if the slope is positive (i.e., the line slopes upward from left to right), it indicates that as the number of hours studied increases, the average grade on the quiz tends to increase as well.

On the other hand, if the slope is negative (i.e., the line slopes downward from left to right), it indicates that as the number of hours studied increases, the average grade on the quiz tends to decrease.

Therefore, the slope of the line of best fit provides valuable information about the relationship between the two variables being plotted and can be used to make predictions about future data points or to identify patterns and trends in the data.

If the loan is a total of $8,465 at 5.9% compounded monthly. at the end of the 12-month repayment period, the student will owe a total of $9246.35 on the loan.

   First, calculate the monthly interest rate by dividing the annual interest rate by 12:

Monthly interest rate = 5.9% / 12 = 0.004917

   Next, calculate the number of months in the repayment period, including the grace period:

Total repayment period = 12 + 6 = 18 months

   Use the formula for calculating the future value of a loan to find the total amount owed at the end of the repayment period:

   FV = PV x (1 + r)^n

   where:

   PV = the present value of the loan (i.e. the amount borrowed)

   r = the monthly interest rate

   n = the number of months in the repayment period

   Plugging in the numbers, we get:

FV = $8,465 x (1 + 0.004917)^18

FV = $9246.35

Therefore, the student will owe a total of $9246.35 on the loan.

Answer: The answer is D

The height of the pole is approximately 10.2 yards tall.

Let's use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the hypotenuse (the longest side).

In this case, the pole is the vertical side of the right triangle, the ground is the horizontal side, and the rope is the hypotenuse. Let's call the height of the pole "h". Then we have:

h² + 11² = 15²

Simplifying:

h² + 121 = 225

Subtracting 121 from both sides:

h² = 104

Taking the square root of both sides:

h = √104

Simplifying:

h ≈ 10.2

Therefore, the pole is approximately 10.2 yards tall.

Answer:

The equation x - y = 7 represents a linear equation with two variables, x and y. To find three ordered pairs (x, y) that satisfy this equation, we can arbitrarily choose values for one variable and solve for the other.

Ordered Pair 1:

Let's choose x = 0:

x - y = 7

0 - y = 7 (Substituting x = 0)

y = -7

So, the first ordered pair is (0, -7).

Ordered Pair 2:

Let's choose y = 0:

x - y = 7

x - 0 = 7 (Substituting y = 0)

x = 7

So, the second ordered pair is (7, 0).

Ordered Pair 3:

Let's choose x = 5:

x - y = 7

5 - y = 7 (Substituting x = 5)

y = -2

So, the third ordered pair is (5, -2).

Therefore, three ordered pairs (x, y) that satisfy the equation x - y = 7 are: (0, -7), (7, 0), and (5, -2).

The better prediction for y, when x = 74, based on the scatter plot, can be found to be 57.

Looking at the scatter plot, the better prediction of y when the value of x is 74 can be found by looking for the values of y that have a value of x that is around 74.

From the scatter plot, we see that the value of x of 74, would correspond with the value of y of 57. We can therefore infer that y = 57 is the better prediction for x = 74.

If piece of cake has area of 100 in² and sweeps angle of 50°, then the radius of the cake is 15.13 inches.

The area of the piece of cake is given as 100 square inches and

The piece of cake sweeps out an angle of 50 degrees, we have to find the radius of the cake;

We know that "Area" of a sector of a circle is given as : A = (θ/360)πr²,

where A = area of the sector, θ is = angle swept by sector, and r is radius of circle,

We know that area of "piece-of-cake" is = 100 square inches and

The "angle-swept' by the piece is = 50 degrees.

Substituting the values in area of sector formula,

We get,

⇒ 100 = (50/360)πr²,

The rectangle with largest area has length 3 and width 3/2, with an area of 9/2.

What is a rectangle?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral. Because the opposing sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.

The equation for the area of a rectangle is length * width. For us here, it would be x * y. We can substitute the equation of the line for y and get

A = x * (6-x)/2

A = 3x - x2/2

To find the maximum of this equation, we first need to find a critical point. So we take the derivative and find the zeros:

A' = 3 - x = 0

x = 3

So we have a critical point at 3, which happens to be the maximum of the area equation. We plug this back into the line equation to get y:

y = (6 - 3)/2 = 3/2

So the rectangle with largest area has length 3 and width 3/2, with an area of 9/2.

Step-by-step explanation:

Therefore, sin θ = 4/5, csc θ = 5/4, and cot θ = -3/4 using trigonometric ratio.

We know that the point (-3, 4) is on the terminal side of the angle θ, and we can use the Pythagorean theorem to find the value of the hypotenuse:

r² = x² + y²

r² = (-3)² + 4²

r² = 9 + 16

r² = 25

r = 5

Now we can find the values of sin θ, csc θ, and cot θ:

sin θ = y/r = 4/5

csc θ = r/y = 5/4

cot θ = x/y = -3/4

Answer:

Step-by-step explanation:

To solve this problem, we need to integrate f'(x) to find f(x), and then evaluate f(3) and f(-1) to compute the expression f(3) - f(-1).

Integrating f'(x)=-4x - 5 with respect to x, we get:

f(x) = -2x^2 - 5x + C

Where C is the constant of integration.

To find the value of C, we can use the initial condition f(0) = 1. Substituting x = 0 and f(x) = 1 into the equation above, we get:

1 = -2(0)^2 - 5(0) + C

1 = C

So, we have:

f(x) = -2x^2 - 5x + 1

Now, we can evaluate f(3) and f(-1) and compute f(3) - f(-1):

f(3) = -2(3)^2 - 5(3) + 1 = -32

f(-1) = -2(-1)^2 - 5(-1) + 1 = 4

f(3) - f(-1) = (-32) - 4 = -36

The probability that all 3 children will be born with the disease is approximately 0.195 or 19.5%.

We have,

Assuming that the probability of a child being born with the disease is independent of whether or not their siblings are born with the disease, we can use the multiplication rule of probability:

P(all 3 children have the disease)

= P(first child has the disease) x P(second child has the disease) x P(third child has the disease)

Since each child has a 57% chance of being born with the disease:

P(all 3 children have the disease)

= 0.57 x 0.57 x 0.57

Now,

P(all 3 children have the disease)

Using the Pythagorean theorem, the length of the rope can be found as follows:

c^2 = a^2 + b^2

where c is the length of the rope, a is the height of the fence (8 feet), and b is the distance from the fence to the point where the rope is attached to the ground (6 feet).

Plugging in the values, we get:

c^2 = 8^2 + 6^2

c^2 = 64 + 36

c^2 = 100

c = √100

c = 10

Therefore, the length of the rope is 10 feet.

Answer:

The length of the rope is 10 feet.

Step-by-step explanation:

To find the length of the rope attached to the top of an 8-foot-tall fence and fastened to the ground 6 feet away, we can use the Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. In this case, the vertical leg is the height of the fence (8 feet) and the horizontal leg is the distance from the base of the fence to where the rope is fastened (6 feet). Therefore, the length of the rope (the hypotenuse) is given by:

hypotenuse^2 = vertical leg^2 + horizontal leg^2

Substituting the values, we get:

hypotenuse^2 = 8^2 + 6^2

hypotenuse^2 = 64 + 36

hypotenuse^2 = 100

Taking the square root of both sides, we get:

hypotenuse = 10

So the length of the rope is 10 feet.
