If the research team continues to run laboratory tests, then the mean number of trials until failure is  8.06.

That a research team has developed a face recognition device to match photos in a database. From laboratory tests, the recognition accuracy is 89% and trials are assumed to be independent. We need to find out the mean number of trials until failure.

(a) Mean number of trials until failure

Using the binomial distribution formula, mean number of trials until failure is given by:

μ = (1 - p)/p

Where p is the probability of success, which is 89% or 0.89. Thus, q = 1 - p = 0.11Substituting the values in the formula, we get:

μ = (1 - 0.89) / 0.89 = 0.11 / 0.89 ≈ 0.124

Thus, the mean number of trials until failure is approximately 0.124 or 1/0.124 ≈ 8.06 trials. Therefore, the mean number of trials until failure is 8.06 trials (approx).

The length of the fencing that the city needs to surround the park will be 380.50 yards.

Assume L is the length and W is the width. Then the area is given as,

A = L × W

And the perimeter is given as,

P = 2(L + W)

The city of vine View is building a new rectangular park for the townspeople. The park will have an area of 8,925 square yards if the width of the park is to be 84 yards. Then the length of the rectangular park is calculated as,

8925 = L × 84

L = 106.25 years

Then the length of the fencing that the city needs to surround the park will be given as,

P = 2(106.25 + 84)

P = 2 × 190.25

P = 380.5 yards

The length of the fencing that the city needs to surround the park will be 380.50 yards.

Answer:

-3

Step-by-step explanation:

The slopes of parallel lines are equal.

If two lines are parallel (that means they are at the same angle, they are always the same distance apart and they never cross), then they have the same slope. Both lines have slope -3

Answer:

-3

Step-by-step explanation:

There is a rule in math that if two slopes are parallel, they must have the same slope. Let's answer the question with this first.

So AB is parallel to CD, meaning they must have the same slope. If AB's slope is -3, then so must CD's. That's the answer to the question.

Coming back to the parallel slope rule, why does this work? Well, if two lines are parallel, it means they never will touch each other, meaning they rise, fall, bend, curve, etc... at the same rate. The slope is the change in how much the line rises divided by the change in how much it runs (moves horizontally). That proves the rule.

f(x) = 4. 8x² function can be used to compute the approximate area, in square inches, of a stop sign if it has a side length of x inches.

A function, which produces single output from either a single input, is an illustration of a rule. Alex Federspiel was contacted to collect the image. An illustration of this is the equation y=x2. For each input of x, there is simply one output of y. Considering that x is actually the input value, we would claim that y is just a rational number.

area = (# of sides * side length^2) / [4 * tan (180/n)]

area = (8 * x^2) / 4 * tan (22.5)

area = 8 x^2 / (4 * 0.41421)

His annual earnings is $131,562.50

Step-by-step explanation:

Here, we want to calculate Dirk’s total annual earnings.

We have three things to add together;

Annual earnings, commission and fees

Annual earnings is already stated = $41,000

Commission

= 3.5% of $2.4 million

= 3.5/100 * 2,400,000 = $84,000

Fees

= $5.25 * 1,250 = $6562.50

Total earnings will be;

41,000 + 6562.5 + 84,000 = $131,562.50

Answer:

8 pi cm^2

Step-by-step explanation:

To answer this question, what we need firstly is the name of the cross section that results from slicing a sphere into half.

The cross section that results is called a hemisphere, which is half the size of the sphere.

But before we can calculate the area of the new cross section, we will need the radius of the original shape.

This is obtainable from the volume of the shape.

Mathematically;

Volume of a sphere = 4/3 * pi * r^3

32/3 * pi = 4/3 * pi * r^3

We can take off pi/3 from both sides so we are left with;

32 = 4r^3

Divide through by 4

r^3 = 8

r is the cube root of 8 = 2 cm

Now we find the area of the hemisphere

Mathematically, the area of a hemisphere is 2 * pi * r^2

using the value of r = 2 cm given above, we have

Hemisphere area = 2 * pi * 2^2 = 8pi cm^2

Answer:

  (a) 16.7 units

Step-by-step explanation:

You want the length of the side opposite the angle 68° in a triangle with a side of length 18 opposite the angle 86°.

The law of sines tells you side lengths are proportional to the sine of the opposite angle:

  AC/sin(B) = BC/sin(A)

  AC = BC·sin(B)/sin(A)

Angle B is a little more than 3/4 of angle A, so the ratio of sines will be more than that value, but less than 1. This tells you AC < (3/4)BC, eliminating choices b, c, d.

The length of AC is about 16.7 units.

__

Additional comment

If you put the numbers into the expression for AC and do the math, you find AC ≈ 16.7301° ≈ 16.7, as we estimated.

68/86 ≈ 0.7907

sin(68)/sin(86) ≈ 0.9294

The ratio of sines of angles versus the angle ratio is only a good match for small angles (generally 5° or less). Otherwise, the ratio of the smallest to largest angle will always be less than the ratio of their sines. (This is because the sine function has decreasing slope for first-quadrant angles.)

The function you're referring to is likely a periodic function, as Fourier series expansions are typically used for periodic functions.

The convergence of the Fourier series expansion depends on the properties of the function, such as its continuity and differentiability.

If the function is continuous and piecewise smooth, then the Fourier series will converge to the function itself.

However, if the function is not continuous or not piecewise smooth, then the Fourier series may not converge uniformly.

In some cases, the Fourier series may converge to a different function altogether, known as a Fourier series of the function.

Therefore, to determine the value at which the Fourier series converges, you would need to analyze the properties of the function itself.

To solve this, you can use the geometric mean theorem. The leg of a right triangle is the geometric mean between the hypotenuse and the portion of the hypotenuse adjacent to the leg.

So that means that 28/y = y/12. You can then use means and extremes of proportions to simplify, and you get y^2 = 336, a.k.a  y = 4 root 21.

Then you do the same thing but with x.

28/x = x/16

x^2 = 448

x = 8 root 7

Answer:

B. x = 8√7, y = 4√21

Step-by-step explanation:

Look at the largest right triangle so the hypotenuse equals 12 + 16 = 28

According to the Pythagorean Theorem: y^2 + x^2 = 28^2

Then for the 2 smaller right triangles, they all the the same side, just called it z

so y^2 = 12^2 + z^2 => z^2 = y^2 - 12^2

and x^2 = 16^2 + z^2 => z^2 = x^2 - 16^2

then y^2 - 12^2 = x^2 - 16^2

y^2 - 144 = x^2 - 256

y^2 = x^2 - 112

Using the first equation

y^2 + x^2 = 28^2 => x^2 = 784 - y^2

So we have y^2 = x^2 - 112

and x^2 = 784 - y^2

then y^2 = (784 - y^2) - 112

y^2 + y^2 = 784 - 112

2y^2 = 672

y^2 = 336

y = 4√21

x^2 = 784 - y^2 = 784 - 336 = 448

x = 8√7
