The measure of the unknown angle is 93°

First we should get the interior angles of the triangle in the right side.

The angle in the left side is given by:

x  + 127° = 180°

x = 180° - 127°

x = 53°

While the angle in the right side is:

y + 146° = 180°

y = 180° - 146°

y = 34°

Now remember that the sum of the interior angles of a triangle must be 180°, then if the angle at the top is z we can write:

z + 34° + 53° = 180°

z = 180° - 34° - 53°

z = 93°

And this angle is a vertical angle of the one we want to find, so the measure of the unknown angle is also 93°.

If a delivery truck is transporting boxes of two sizes: large and small. there are 70 large boxes and 65 small boxes in the truck.

Let's assume that x represents the number of large boxes, and y represents the number of small boxes.

We know that there are 135 boxes in total, so:

x + y = 135

We also know that the total weight of the boxes is 5475 pounds, so:

55x + 25y = 5475

Now we have a system of linear equations with two variables. We can use substitution or elimination to solve for x and y. Let's use substitution:

From the first equation, we can solve for x in terms of y:

x = 135 - y

Substitute this expression for x into the second equation:

55x + 25y = 5475

55(135 - y) + 25y = 5475

Simplify and solve for y:

7425 - 55y + 25y = 5475

30y = 1950

y = 65

Now we can use the first equation to solve for x:

x + y = 135

x + 65 = 135

x = 70

Therefore, there are 70 large boxes and 65 small boxes in the truck.

The historical rate of defective widgets produced by ACME Corporation was 7%. Approximately, 91.2 is the standard deviations is the point estimate from 7%.

In statistics, standard deviation is a measure of the amount of variation or distribution of a set of values. A low standard deviation indicates that the values ​​tend to be close to the ensemble mean (also called the expected value), while a high standard deviation indicates that the values ​​are spread over a wider range.

The standard deviation can be abbreviated SD, and is most commonly used in mathematical texts and equations with the lowercase Greek letter σ (sigma) for the population standard deviation, or the Latin letter s for the standard deviation of the sample.

The standard deviation of a random variable, sample, population, data set, or probability distribution is the square root of its variance. It is algebraically simpler than the mean absolute deviation, although less robust in practice. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same units as the data.

According to the Question:

Given that:

Defective widgets produced by ACME corporation was 7%

Answer:

384 cm^2

Step-by-step explanation:

Let the lengths of the sides of the right-angled triangle be 6x, 8x, and 10x, where x is a constant.

Since the perimeter of the triangle is 96 cm, we have:

6x + 8x + 10x = 96

24x = 96

x = 4

Therefore, the lengths of the sides of the triangle are 24 cm, 32 cm, and 40 cm.

The area of a right-angled triangle is given by the formula:

Area = (1/2) * base * height

where the base and height are the two shorter sides of the triangle.

Using the Pythagorean theorem, we can determine that the base and height of the triangle are 24 cm and 32 cm, respectively.

Therefore, the area of the triangle is:

Area = (1/2) * base * height

Area = (1/2) * 24 cm * 32 cm

Area = 384 cm^2

Therefore, the area of the right-angled triangle is 384 cm^2.

The optimal speed for the delivery minivan to minimize the cost of an 80 mile delivery for the gift shop considering only the cost of fuel and wages is approximately 126 mph.

Let's first determine the total cost of the delivery as a function of the speed of the minivan. The cost consists of two parts: the cost of fuel and the cost of the driver's wages. Since the driver's rate is $20 per hour and the delivery is 80 miles, the cost of the driver's wages is:

W = $20 × (80/V) = $1600/V

The cost of fuel is given by the formula C = [tex]0.005V^2[/tex], where V is the speed of the minivan in mph. The total cost of the delivery is therefore:

C(V) = [tex]0.005V^2 + 1600/V[/tex]

To find the speed that minimizes the cost of the delivery, we need to find the value of V that makes the derivative of C(V) equal to zero:

C'(V) = [tex]0.01V - 1600/V^2[/tex]

0 = [tex]0.01V - 1600/V^2[/tex]

0 = [tex]V^3 - 160000[/tex]

[tex]V^3[/tex] = 160000

V = cuberoot(160000) = 40√10

The exact speed that minimizes the cost of the delivery is V = 40√10 mph. Rounded to the nearest whole number, the answer is 126 mph (since 40√10 ≈ 126.49).

The 8th term of the given geometric sequence is -156250.

A sequence of numbers is called a geometric sequence if each term, except for the first term, is obtained by multiplying the previous term by a constant factor, which is called the common ratio.

The given sequence is a geometric sequence where each term is obtained by multiplying the previous term by -5.

So, the common ratio (r) between any two consecutive terms is -5.

To find the 8th term, we can use the formula for the nth term of a geometric sequence:

[tex]an = a1 * r^{(n-1)[/tex]

where,

an = 8th term

a1 = first term = 2

r = common ratio = -5

n = 8 (since we want to find the 8th term)

Therefore, substituting the values in the formula, we get:

[tex]a8 = 2 * (-5)^{(8-1)}\\\\a8 = 2 * (-5)^7\\\\a8 = 2 * (-78125)\\\\a8 = -156250[/tex]

The function has a local maximum at x = 1/3 and a local minimum at x = -4/3.

A quadratic equation is a second-order polynomial equation in a single variable x

ax²+bx+c=0

with a ≠ 0 . Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots x can be found by completing the square,

ax²+bx+c=0

To analyze the function F(x) = -2x² - 6x³ + 4x + 1, we can begin by finding its derivative:

F'(x) = -4x - 18x² + 4

Then, we can find the critical points of the function by setting F'(x) equal to zero and solving for x:

-4x - 18x² + 4 = 0

Using the quadratic formula, we get:

x = (-(-4) ± ((-4)² - 4(-18)(4))) / (2(-18))

Simplifying, we get:

x = (-(-4) ± (400)²) / (-36)

x = (-(-4) ± 20) / (-36)

x = 1/3 or x = -4/3

So the critical points of the function are x = 1/3 and x = -4/3.

To determine the nature of these critical points, we can use the second derivative test.

F''(x) = -4 - 36x

Plugging in x = 1/3, we get:

F''(1/3) = -4 - 36(1/3) = -16 < 0

So x = 1/3 is a local maximum.

Plugging in x = -4/3, we get:

F''(-4/3) = -4 - 36(-4/3) = 40 > 0

So x = -4/3 is a local minimum.

Therefore, the function has a local maximum at x = 1/3 and a local minimum at x = -4/3.
