Answer:

B: The mean is 0 and the distribution will not be approximately normal

Step-by-step explanation:

It is true that the mean is 0 because it is the difference in the population proportions, 0.01−0.01. However, normality cannot be assumed because the sample sizes are not large enough.

The sample distribution is defined as the probability distribution of a given sample based on statistics.

The correct option is (a).

Given:

The defective parts produced by each machine is 1%.

The sample Size is 100.

Calculate the proportion of the defective parts.

[tex]\dfrac{1}{100}=0.01[/tex]

Thus, the mean of each machine is 0.01.

Now, the mean difference between both machine is 0 and proportion will be normally distributed.

The value of [x] will be equivalent to x = 3.5.

        [tex]y=log_{e} (x)[/tex]

Given is the logarithmic equation as

2log(4x) − log(49) = 2

2log(4x) = 2 + log(49)

2{log(4) + log(x)} = 2 + log(49)

{log(4) + log(x)} = {2 + log(49)}/2

log(4) + log(x) = 1 + log(49)/2

log(4) + log(x) = 1.85

log(x) = 1.85 - log(4)

log(x) = 1.25

x = e^(1.25)

x = 3.5 {approx.}

Therefore, the value of [x] will be equivalent to x = 3.5.

Step-by-step explanation:

The area of a triangle can be given as [tex]\frac{1}{2}\cdot b \cdot h[/tex]. Notice that a base of the triangle is given as 4 units, and the height is marked as 5 units. We know that the segment marked as 5 units is the height of the triangle because it forms a [tex]90^{\circ}[/tex] with the segment marked as 4 units and meets a vertex of the triangle.

Therefore, the area of the triangle is:

[tex]\frac{1}{2}\cdot 4 \cdot 5 = \fbox{$10$}[/tex].

Step-by-step explanation:

From the question we are told that

Equation of cross section is [tex]y+5= \frac{1}{2x^2}[/tex]

Generally the equation can be rewritten mathematically as

  [tex]y+5= \frac{1}{2}x^2[/tex]

  [tex]x^2=(y+5)2[/tex]

  [tex](x-0)^2=(y-(-5))2[/tex]

Generally the equation of a parabola with vertical axis is mathematically given by

[tex](x - h)2 = 4p(y - k)[/tex]

Therefore  comparing equations

[tex](x-0)^2=(y-(-5))2[/tex]

[tex]4p=2[/tex]

[tex]p=2/4[/tex]

The distance from the bulb to the vertex of the cross section is given by

Answer:

The charges will be the same after 10 miles.

Step-by-step explanation:

Long Beach Towing Company:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

[tex]L(x) = 40 + 5x[/tex]

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

[tex]F(x) = 70 + 2x[/tex]

After how many miles the charges for the two companied will be the same?

This is x for which:

[tex]L(x) = F(x)[/tex]

So

[tex]40 + 5x = 70 + 2x[/tex]

[tex]5x - 2x = 70 - 40[/tex]

[tex]3x = 30[/tex]

[tex]x = \frac{30}{3}[/tex]

[tex]x = 10[/tex]

The charges will be the same after 10 miles.

Answer:

The numbers described here are 39 and 11.

Step-by-step explanation:

Let's call the numbers a and b, a being the larger. We're told two things:

The larger of the two numbers is 17 more than twice the smaller.

Which we can express as:

a = 2b + 17

When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6

And that can be expressed as:

a = 3b + 6

We can now take those two expressions and, noting that they both define a, we can say that they are equivalent, and solve for b:

2b + 17 = 3b + 6

3b - 2b = 17 - 6

b = 11

With b found, we can now take either of the first expressions, and solve for a:

a = 2b + 17

a = 2(11) + 17

a = 22 + 17

a = 39

Now we can check whether that is correct by plugging it into the other expression and seeing if b still comes to 11:

a = 3b + 6

39 = 3b + 6

3b = 33

b = 11

So we know that the answer is correct.

Answer:

5 full pieces

Step-by-step explanation:

Given

[tex]Board\ Length = 7\frac{3}{4}ft[/tex]

[tex]Pieces = 1\frac{1}{3}ft[/tex]

Required

Determine the number of pieces that can be cut from the board

This is calculated by dividing the board length by the length of each piece.

[tex]Number = \frac{Board\ Length}{Pieces}[/tex]

[tex]Number = 7\frac{3}{4} / 1\frac{1}{3}[/tex]

Convert to improper fractions

[tex]Number = \frac{31}{4} / \frac{4}{3}[/tex]

Change / to *

[tex]Number = \frac{31}{4} * \frac{3}{4}[/tex]

[tex]Number = \frac{31*3}{4*4}[/tex]

[tex]Number = \frac{93}{16}[/tex]

[tex]Number = 5.8125[/tex]

Round down to discard the decimal parts

[tex]Number = 5[/tex]

Hence, the carpenter can cut full-sized 5 pieces

How to solve system of two equations:

First of all, we should get one variable in terms of other variable in one equation and substitute this variable in another equation. And solving that we get two variables value.

If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing.

Here,

let's consider price of hot dogs = x and price of hamburgers = y

then, 164x + 74y = $706 --- ( 1 )

and 256x + 61y = $884 --- ( 2 )

Now,  from eq - 1 we get x = ($706 - 74y) / 164

Substitute this x value in eq - 2,

256($706 - 74y)/164 + 61y = $884

=> $706*256 - 74y*256 + 61y*164 = $884 * 164

=> 180,736-8940y = 144,976

=> 180,736 - 144,976 = 8940y

=> 35,760/8940 = y

=> y = $4.

By substituting in eq - (1) we get x = $2.5

So, The price of hot dog = $2.5
