The general form of the regression equation is y = a + bx

A regression equation is a statistical model used to identify the relationship between a dependent variable (Y) and one or more independent variables (X) in a dataset. The regression equation is used to make predictions by identifying how a change in one variable affects the other variables. The general form of the regression equation is y = a + bx, where 'y' is the dependent variable, 'x' is the independent variable, 'a' is the intercept value, and 'b' is the slope value.

Therefore, the general form of the regression equation is y= a+bx

Given :

n = 200, p = 80% = 0.8, q = 1 - p = 0.2

\($\mu = np$\)

  \($= 200 \times 0.8 = 160$\)

\($\sigma= \sqrt{npq}$\)

\($\sigma= \sqrt{200 \times 0.8 \times 0.2}$\)

   = 5.6569

a). x = 169.5

∴ \($z = \frac{x- \mu}{\sigma}$\)

  \($z = \frac{169.5- 160}{5.6569}$\)

     = 1.6794

\($P(x \geq 170) = P(z>1.6794) = 0.0465$\)

Therefore, probability that the stolen goods were not recovered in 170 robberies or more is = 0.0465

b). x= 149.5

   \($z = \frac{x- \mu}{\sigma}$\)

   \($z = \frac{149.5- 160}{5.6569} = -1.8561$\)

\($P(x \geq 150) = P(z>-1.8561) = 0.9683$\)

Step-by-step explanation:

The point on the surface with a positive x-coordinate and at which the tangent plane is parallel to the provided plane 12x + 54y + 84z = 2 is approximately (181, -12, 59).

To determine the point on the surface defined by the equation x² + 3y² + 62² = 36672 that has a positive x-coordinate and at which the tangent plane is parallel to the provided plane 12x + 54y + 84z = 2, we can follow these steps:

1. Calculate the gradient vector of the surface equation:

The gradient vector of the surface equation x² + 3y² + 62² = 36672 is:

∇f = (2x, 6y, 0).

2. Calculate the normal vector of the provided plane equation:

The normal vector of the plane equation 12x + 54y + 84z = 2 is given by the coefficients of x, y, and z:

n = (12, 54, 84).

3. For the tangent plane to be parallel to the provided plane, the gradient vector of the surface must be perpendicular to the normal vector of the plane.

This implies that the dot product of the gradient vector and the normal vector must be zero:

∇f · n = 2x(12) + 6y(54) + 0(84) = 24x + 324y = 0.

4. We want to obtain the point on the surface with a positive x-coordinate, so we set x > 0.

From the equation 24x + 324y = 0, we can solve for y:

24x + 324y = 0

324y = -24x

y = (-24/324)x

y = (-2/27)x.

5. Substitute this expression for y into the surface equation x² + 3y² + 62² = 36672:

x² + 3((-2/27)x)² + 62² = 36672

x² + (4/729)x² + 3844 = 36672

(730/729)x² = 32828

x² = (32828 * 729) / 730

x² = 32828.

6. Take the positive square root to obtain x:

x = √32828

x ≈ 181.

7. Substitute this value of x back into the equation y = (-2/27)x to obtain y:

y = (-2/27)(181)

y ≈ -12.

8. Substitute the values of x and y into the surface equation to obtain z:

181² + 3(-12)² + z² = 36672

32761 + 3(144) + z² = 36672

32761 + 432 + z² = 36672

33193 + z² = 36672

z² = 3479

z ≈ 59.

Answer:

The answer tot he question provided is 25.

Answer:

Total surface area = 132 square feet

Step-by-step explanation:

Surface area of the triangular prism = Area of the triangular bases + Area of the lateral rectangular sides

Area of the triangular surface = \(\frac{1}{2}(\text{Base})(\text{Height})\)

                                                 = \(\frac{1}{2}\times 5\times 4\)

                                                 = 10 square feet

Area of the rectangular side with dimensions 5ft by 7ft,

Area = 5 × 7 = 35 square feet

Area of the rectangular side with dimensions 7ft by 4ft,

Area = 7 × 4 = 28 square feet

Area of the rectangular side with dimensions 7ft by 7ft,

Area = 7 × 7 = 49 square feet

Total surface area = 2(10) + 35 + 28 + 49

                               = 132 square feet

Answer:

Cos(θ) = 7/√58 ; Tan(θ) = 3/7 ; Csc(θ) = √58/3

Step-by-step explanation:

First, let's solve for the hypotenuse by using the Pythagorean Theorem.

a² + b² = c²

⇒ 7² + 3² = c²

⇒ 49 + 9 = c²

⇒ 58 = c²

⇒ √58 = c

Now that we know the hypotenuse is √58, we can solve for the trig ratios.

Cos(θ) = adjacent/hypotenuse = 7/√58

Tan(θ) = opposite/adjacent = 3/7

Csc(θ) = hypotenuse/opposite = √58/3

The area of the trapezoid is 30x + 42. Option C

Area = 1/2 × 12(2x + 3 + 3x + 4)

collect the like terms, we have;

The absolute maximum value is 20/17, which occurs at x = 5, and the absolute minimum value is 4/5, which occurs at x = 1.

To find the absolute maximum and minimum values of the function f(x) = 8x/(6x + 4) on the interval (1, 5), we need to find the critical points of the function within the interval and evaluate the function at those points, as well as at the endpoints of the interval.

First, let's find the derivative of the function:

f(x) = 8x/(6x + 4)

f'(x) = [8(6x + 4) - 8x(6)] / (6x + 4)^2

f'(x) = [8(2)] / (6x + 4)^2

f'(x) = 16 / (6x + 4)^2

The critical points occur when f'(x) = 0 or is undefined. However, since f'(x) is always positive on the interval (1, 5), there are no critical points within the interval.

Next, let's evaluate the function at the endpoints of the interval:

f(1) = 8(1)/(6(1) + 4) = 8/10 = 4/5

f(5) = 8(5)/(6(5) + 4) = 40/34 = 20/17

Finally, we need to determine which of these values is the absolute maximum and which is the absolute minimum.

Since f(x) is always positive on the interval (1, 5), the function can never be less than 0. Therefore, the absolute minimum value is the smallest value of f(x) on the interval, which occurs at x = 5, where f(5) = 20/17.

To find the absolute maximum value, we compare the values of f(1), f(5), and the maximum value of f(x) as x approaches the endpoints of the interval. We can use the fact that the function is continuous on the closed interval [1, 5] to find the maximum value.

As x approaches 1, we have:

f(x) = 8x/(6x + 4) → 8/10 = 4/5

As x approaches 5, we have:

f(x) = 8x/(6x + 4) → 40/34 = 20/17

Therefore, the absolute maximum value is 20/17, which occurs at x = 5, and the absolute minimum value is 4/5, which occurs at x = 1.

The sum of 10 will occur approximately 50 times if the two number cubes are rolled 600 times.

To estimate the number of times that the sum will be 10 if the two number cubes are rolled 600 times, we need to consider the probability of getting a sum of 10 on a single roll.

The possible combinations that result in a sum of 10 are (4,6), (5,5), and (6,4). Each of these combinations has a probability of 1/36 (since there are 36 possible outcomes in total when rolling two number cubes).

Therefore, the probability of getting a sum of 10 on a single roll is (1/36) + (1/36) + (1/36) = 3/36 = 1/12.

To estimate the number of times this will happen in 600 rolls, we can multiply the probability by the number of rolls:

(1/12) x 600 = 50

So we can estimate that the sum of 10 will occur approximately 50 times if the two number cubes are rolled 600 times.
