Assume that the helium porosity (in percentage) of coal samples taken from any particular seam is normally distributed with true standard deviation 0.77. (a) Compute a 95% CI for the true average porosity of a certain seam if the average porosity for 21 specimens from the seam was 4.85. (Round your answers to two decimal places.)

Answers

Answer:

The 95% CI for the true average porosity of a certain seam is (4.52, 5.18).

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96\frac{0.77}{\sqrt{21}} = 0.33[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 4.85 - 0.33 = 4.52.

The upper end of the interval is the sample mean added to M. So it is 4.85 + 0.33 = 5.18

The 95% CI for the true average porosity of a certain seam is (4.52, 5.18).

You and a friend went to Taco Bell for lunch.
You ordered 3 soft tacos and 3 burritos for
$11.25. Your friend ordered 4 soft tacos and
2 burritos for $10. How much do soft tacos cost?
How much do burritos cost

Answers

Let’s make a pair of equations, one for what you ordered, one for what your friend ordered. We’ll have x represent soft tacos and y represent burritos.

Your order: 3x + 3y = 11.25

Your friend’s order: 4x + 2y = 10

The first thing I gather using the information above is that burritos are more expensive then tacos, right? Your order is more expensive, with 1 less taco and 1 more burrito than your friend’s. But now we need to find out just how much more burritos cost.

To do that, pick an equation and simplify it for either x or y. I’ll choose the second equation, because it has a simpler answer. Let’s see what y equals for that one.
2y = 10 - 4x
y = 5 - 2x

Burritos cost 5 minus the cost of two tacos. Just replace y with this in our other equation.
3x + 3(5-2x) = 11.25
Use the distributive property.
3x + 15 - 6x = 11.25
15 - 3x = 11.25
-3x = -3.75
3x = 3.75
One taco costs $1.25
It’s easy to find out what the other variable equals once you have one already. Just pick either of the equations and know how much a taco costs. I’ll jump back to the second one.

4(1.25) + 2y = 10
5 + 2y = 10
2y = 5
y = 2.5

As predicted, burritos cost more. One taco costs $1.25. One burrito costs $2.50. With problems like these, you can always double-check the answers if you’d like. Just plug in the numbers.

The number of positive 10 digit numbers that can be made using seven ones and three zeros is; 28

How to solve probability combinations?

We want to find the number of positive 10 digit numbers that can be made using seven ones and three zeros.

Now, the leftmost position digit cannot be 0 and as such it is 1, due to the fact that there are no other possibilities.

The rightmost position therefore must be 0 in order to fill the need for an even number.

Thus, we have 8 remaining positions that we need to fill with six ones and two zeros using an arbitrary manner.

This means that we can place two digits of zero among 8 positions by using combination formula as;

⁸C₂ = 8!/(2! * 6*)

The roots of the quadratic equation x² - x - 56 = 0 is x = -7 or x = 8

What is Quadratic Equation?

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 of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the equation be represented as A

Now , the value of A is

x² - x - 56 = 0   be equation (1)

On simplifying the equation , we get

x² - 8x + 7x - 56 = 0

Taking the common terms in the equation , we get

x ( x - 8 ) + 7 ( x - 8 ) = 0

Now , on factorizing the equation , we get

( x + 7 ) ( x - 8 ) = 0

We have two factors which can solve the equation ,

when ( x + 7 ) = 0

Subtracting 7 on both sides of the equation , we get

x = -7

And , when ( x - 8 ) = 0

Adding 8 on both sides of the equation , we get

x = 8

Therefore , the roots of the equation are x = -7 and x = 8

Hence , the quadratic equation is solved

Answer:

x = 8

x = -7

Step-by-step explanation:

To find the solutions of the quadratic equation x^2 - x - 56 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this equation, a = 1, b = -1, and c = -56. Plug these values into the formula and calculate the discriminant (the value inside the square root):

Discriminant (D) = b^2 - 4ac = (-1)^2 - 4(1)(-56) = 1 + 224 = 225

Now, calculate the two possible solutions:

x1 = (-(-1) + √225) / (2(1)) = (1 + 15) / 2 = 16 / 2 = 8

x2 = (-(-1) - √225) / (2(1)) = (1 - 15) / 2 = -14 / 2 = -7

So, the correct solutions to the equation x^2 - x - 56 = 0 are:

x = 8 (x = 0 is not a solution)

x = -7

Option (3)

Step-by-step explanation:

Volume of the cylinder = 40 ft³

Since, volume of a cylinder is given by the expression,

V = [tex]\pi r^{2}h[/tex]

Here, r = radius of the circular base

h = Height of the cylinder

40 = [tex]\pi r^{2}h[/tex]

[tex]h=\frac{40}{\pi r^2}[/tex] ------(1)

Volume of a cone = [tex]\frac{1}{3}\pi r^{2} h[/tex]

By substituting the value of 'h' from equation (1)

Volume of the cone = [tex]\frac{1}{3}\pi r^{2}(\frac{40}{\pi r^{2} } )[/tex]

                                 = [tex]\frac{1}{3}(40)[/tex] ft³

Therefore, Option (3) will be the correct option.

When working with piping offsets, which are based on right triangles. Which of the following angle measurements will you see as a standard elbow angle? a. 22.5, b. 60, c. 70. d.45

Answers

Answer:

  d.  45°

Step-by-step explanation:

You want to know which from your list is a standard elbow angle.

Elbow

An elbow is a pipe fitting that is used to change the direction of piping. Elbows can be used together to produce an offset and/or a change in the plane of the piping.

Standard elbow angles commonly are 90°, 45°, and, less commonly, 22.5°. The greater the angle, and/or the smaller the bend radius, the more resistance to flow it has.

The best choice of answer here is 45°.

__

Additional comment

The typical elbow has the same kind of threads on both sides. A "street elbow" has male threads on one side and female threads on the other side.

Elbow joints are not necessarily threaded. They may also be soldered, welded, or compression joints.

What are the zeros of the function?

A function's zeros, also known as roots or solutions in mathematics, are the values of the independent variable (typically represented as x) for which the function evaluates to zero. In other terms, a function's zeros are the x-values that make the function equal to zero.

To find the zeros of the function f(x) = (-x - 2) (-2x - 3), we set the function equal to zero and solve for x:

(-x - 2) (-2x - 3) = 0

To find the zeros, we need to consider each factor separately and set them equal to zero:

First factor: -x - 2 = 0

Solving for x, we add 2 to both sides:

-x = 2

Multiplying both sides by -1 to isolate x:

x = -2

Second factor: -2x - 3 = 0

Solving for x, we add 3 to both sides:

-2x = 3

Dividing both sides by -2 to isolate x:

x = -3/2 or -1.5

So, the zeros of the function are x = -2 and x = -1.5.

Therefore, the lesser value of x is -2, and the greater value of x is -1.5.
