What are rules for transformations and how do they work

Answer:

Mg/mi. A Company Has 16 Cars Of This Model In Its Fleet. ... The level of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) in d ... organic gas (NMOG) in the exhaust over the useful life (150,000 miles of driving) of cars of a particular model varies Normally with mean 85 mg/mi and standard deviation 6 mg/mi.

Step-by-step explanation:

Using the normal distribution and the central limit theorem, it is found that the level is 88.49 mg/mi.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

This level is the 1 - 0.01 = 99th percentile, which is X when Z has a p-value of 0.99, so X when Z = 2.327. Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]2.327 = \frac{X - 85}{1.5}[/tex]

[tex]X - 85 = 2.327(1.5)[/tex]

[tex]X = 88.49[/tex]

The level is 88.49 mg/mi.

Step-by-step explanation:

Answer:

60 pound

Step-by-step explanation:

Calculation for How many pounds of regular coffee should he use

Let pounds of regular coffee be x

Let value of regular coffee be 5x

Let cost of gourmet coffee be 8

Let value of gourmet coffee be 8*30

Let pounds of mixture be 30+x

Let value of mixture be 6(30+x)

Equation:

5x+(8*30)=6(30+x)

5x+240=6(30+x)

Now Let Solve for x:

5x+240=180+6x

240-180=6x-5x

60=1x

x=60/1

x=60

Therefore, he should use $60 pounds of regular coffee

Answer:

slope = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + y = 3 ( subtract x from both sides )

y = - x + 3 ← in slope- intercept form

with slope m = - 1

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1}[/tex] = 1

Answer:

9.286

Step-by-step explanation:

I'm not guaranteeing this answer. If this is correctly written without any indication of how to deal with x, then here is as much as you can do.

850-53x m= 720-39x m                         Subtract 720 from both sides.

850 - 720 - 53x = 720 - 720 - 39xm      Combine

- 53xm + 130 = - 39xm                             Add 53x

-53x+53xm + 130 = -39x + 53xm            Combine

                      130 = 14xm                         Divide by 14

xm = 130/14

xm = 9.28

===============================

You can use the same steps above. I'm abbreviating the steps because they are the same.

I'm sure there is more to the problem, but I can't imagine what it is. If you have additional directions, put it under this answer. I will get it as a comment.

850-53m= 720-39m

850 - 720 - 53m = - 39m

130 - 53m = - 39m

130 = -39m + 53m

130 = 14m

130/14 = m

m =9.286

Answer:C 10x+18y>3200

Step-by-step explanation:

Answer:

321

Step-by-step explanation:

Conversion of 86 to base 5 will be done through base 10 to base 5 and it will be (321)₅.

To convert any number to base 10 we have to multiply its unit digit by 10⁰ and its tenth digit by 10¹.

After it, we need to add it. It will give us a number of the 10 bases.

Conversion of any 10 base number into base 5

To convert any number to base 5 we need to divide by 5 and write the remainder each time thus we need to write the quotient from down to up.

Converting 86 to base 10

⇒ 8ₓ10¹ +8ₓ[tex]10^0[/tex]

⇒ 86₁₀

Converting 86₁₀ into 86₅

When the number 86 is converted in a base of 5 will be (321)₅

Since we need to go down to up to 321₅ will be the correct answer.

Step-by-step explanation:

1AA = 426

What an odd class...

Answer:

426 in decimal.

Step-by-step explanation:

Step 1) Count the digits in 1AA, which in this case is 3 digits, and convert each digit to Hex.

Step 2) Starting from the last number in Step 1, multiply the first number with 1, the second number with 16, and the third number with 256.

Step 3) Add up all the numbers you got in Step 2 to get the answer.

Following the instructions above, your math should look like this:

10 x 1 = 10

10 x 16 = 160

1 x 256 = 256

10 + 160 + 256 = 426

Thus, we got the following answer:

1AA = 426

Step-by-step explanation:

Answer:

Speed = 3.75 miles per hour.

Step-by-step explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex]

[tex]S = \frac{d}{t}[/tex]

Given the following data;

Distance, d = 3/4 miles

Time, t = 1/5 hour

Substituting into the equation, we have;

[tex]Speed, S= \frac{3/4}{1/5}[/tex]

[tex]Speed, S = \frac{3}{4}*5[/tex]

[tex]Speed, S = \frac{15}{4}[/tex]

Speed, S = 3.75mph.

Therefore, Josie's speed is 3.75 miles per hour.

Answer:

[tex]\mathbf{V = \dfrac{16}{3}}[/tex]

Step-by-step explanation:

From the information given:

A = (4,0,0)   B = (0,4,0)    C = (0,0,1)   D = (4,4,1)

[tex]\overline{ AB}[/tex] = (0,4,0) - (4,0,0) = (-4, 4, 0)

[tex]\overline{ BC} =[/tex] (0,0,1) - (0,4,0) = (0, -4, 1)

[tex]\overline{ CD}[/tex] = (4,4,1) - (0,0,1) = (4, 4, 0)

The Volume of the tetrahedron [tex]V = \dfrac{1}{6} \bigg| AB \times BC \times CD \bigg|[/tex]

The Volume of the tetrahedron [tex]V = \dfrac{1}{6} \left\begin{vmatrix}-4,&4&0\\0,&-4&1\\4&4&0\end{vmatrix}\right[/tex]

[tex]V = \dfrac{1}{6}\bigg [ -4(-4 *0 - 1*4) -4(0*0-1*4) +0(0*4--4*4) \bigg ][/tex]

[tex]V = \dfrac{1}{6}\bigg [ -4(0 - 4) -4(0-4) +0(0+16) \bigg ][/tex]

[tex]V = \dfrac{1}{6}\bigg [ 16 + 16 +0 \bigg ][/tex]

[tex]V = \dfrac{1}{6}\bigg [ 32 \bigg ][/tex]

[tex]\mathbf{V = \dfrac{16}{3}}[/tex]
