An ethanol railroad tariff is a fee charge for shipments of ethanol on public railroads. The Agriculture Marketing Service publishes tariff rates for railroad-car shipments of ethanol in the Biofuel Transportation Database. Assuming that the standard deviation of such tariff rates is $1150, determine the probability that the mean tariff rate of 500 randomly selected railroad-car shipments of ethanol will be within $100 of the mean tariff rate of all railroad-car shipments of ethanol.

Answers

Answer 1

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

[tex]\sigma=1150[/tex]

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ [tex]\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }[/tex]

On substituting the values, we get

⇒      [tex]=\frac{1150}{\sqrt{500} }[/tex]

then,

⇒      [tex]=P(-1.94<Z<1.94)[/tex]

⇒      [tex]=P(Z<1.94)-P(Z < -1.94)[/tex]

On using the table of P, we get

⇒      [tex]=0.9738 - 0.0262[/tex]

⇒      [tex]=0.9476[/tex]

Yall plzz helpp I dont want to fail math "what is the longest walking stick that can be placed in the bottom of a truck of length 80 cm and width 60cm"

Answers

Given:

Length of the truck = 80 cm

Width of the truck = 60 cm

To find:

The longest walking stick that can be placed in the bottom of a truck.

Solution:

The longest walking stick that can be placed in the bottom of a truck is the diagonal of the truck.

We know that, the diagonal of a rectangle is:

[tex]d=\sqrt{l^2+w^2}[/tex]

Where, l is the length and w is the width.

Putting [tex]l=80[/tex] and [tex]w=60[/tex], we get

[tex]d=\sqrt{(80)^2+(60)^2}[/tex]

[tex]d=\sqrt{6400+3600}[/tex]

[tex]d=\sqrt{10000}[/tex]

[tex]d=100[/tex]

Therefore, the length of the longest walking stick that can be placed in the bottom of a truck is 100 cm.

Given:

Bella bought packs of stickers to give to her friends.

Cost of each pack of stickers = $4

Total amount spent on packs of stickers = $12

To find:

The equation for the given statement.

Solution:

Let s be the number of packs of stickers.

Cost of one pack of stickers = $4

Cost of s packs of stickers = $4s

Total amount spent on packs of stickers is $12. So,

A student worked out the following problem: Solve: 8x + 10 – 6x + 4 = 24 Step 1: 2x + 14 = 24 Step 2: 2x = 38 Step 3: x = 19

A) There is an error in step 1
B) There is an error in step 2
C) There is an error in step 3
D) There is no error

Answers

Answer

b

Step-by-step explanation:

Answer:

B) There is an error in step 2.

Step-by-step explanation:

When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).

After combing your like terms, you now have the equation 2x+14=24.

You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10

This is where the student made the mistake. Instead of subtracting 14, they added 14.

The final step would be to divide by 2 on both sides.

At the end of the problem, you are left with x=5.

Determine the difference, in square miles, between the area of Texas and the area of Rhode Island. Write your answer in scientific notation.

Answer: _________________ square miles

Answers

Answer:

2.6779*10^5

Step-by-step explanation:

2.69 * 10^5 - 1.21 * 10^3

This is 2.6779*10^5 :)

The difference between the areas of Texas and the area of Rhode Island is given by equation A = 2.6779 x 10⁵ miles²

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the area of Texas be p = 2.69 x 10⁵ miles²

Let the area of Rhode Island be q = 1.21 x 10³ miles

Now , the difference of areas A = p - q

On simplifying the equation , we get

The difference between the area of Texas and the area of Rhode Island A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles

A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles

A = 10³ ( 2.69 x 100 - 1.21 )

On further simplification , we get

A = 10³ ( 269 - 1.21 )

A = 267.79 x 10³

A = 2.6779 x 10⁵ miles²

Hence , the difference in areas is 2.6779 x 10⁵ miles²
