Answer:

line DC

Step-by-step explanation:

Hello,

2 different points define a line, right?

so you can exclude the two first answers as they involve 1 and 3 points.

There is no point M, right? you can get rid of the third answer.

There are the two points D and C which defines the line DC which is m

thanks

The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge

Blababa [14]

Answer:

L = f(J, K, F)

L = (JK²)/F

So, as the formula appears, the appropriate units will be option A.

Unit for number of laughs = (jokes*knowledge²) / familiarity

Just like the formula suggests.

Step-by-step explanation:

Complete Question

The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K) and the familiarity with the jokes (denoted by F) using this formula: L = (JK²)/F

Select an appropriate unit for number of laughs:

A) (jokes*knowledge²) / familiarity

B) familiarity / (jokes*knowledge²)

C) familiarity² / (jokes*knowledge)

D) (jokes*knowledge) / familiarity²

Solution

L = f(J, K, F)

where

L = number of laughs

J = number of jokes

K = amount of knowledge about the joke material

F = familiarity with the jokes

Analysing how the dependent variable depends on each of the independent variables.

- Number of jokes

The number of laughs will increase with the number of jokes and vice versa. It can be stated that there is a direct variation between the number of laughs and number of jokes.

- Amount of knowledge about the joke material

The more one understands the joke material, the funnier the joke. In fact, the joke can be termed funnier when one understands the joke material deeply. The direct variation of number of laughs to knowledge about joke material isn't just enough, the number of laughs varying directly as the square of the knowledge of joke material seems more fitting.

- Familiarity with the joke

The more familiar one is with a joke, the less funny it is. Hence, it's an inverse relationship between number of laughs and the familiarity with the joke.

L = (JK²)/F

So, as the formula appears, the appropriate units will be

(jokes*knowledge²) / familiarity

Just like the formula suggests.

Hope this Helps!!!

Match the following equation to the correct situation.

ANTONII [103]

Answer:

A. Last month's electricity bill was 5.4 kW-h less than 30% of this month's bill.

Step-by-step explanation:

The given expression is:

$30\%(b-18)=30\%b-5.4$

The above expression tells us that 30% is of the quantity 'b' and 5.4 is being subtracted from the result of the percentage.

Choice A:

If we consider the present month's bill as 'b'. Then 30% of present month's bill can be represented as 30% of b = 30%b.

Now, if the previous month's bill is 5.4 kW-h less than 30% of this month's bill, then this statement can be represented as:

Previous bill = 30% of Current bill - 5.4 = $30\%b-5.4$

Hence, choice A justifies the given expression.

Choice B:

The expression for choice B could be number of songs available for download from 30% of 'b' artists is $30%b$ .

Choice C:

5.4 speeches doesn't make any sense.

Choice D:

5.4 less than 'b' bowls mean $b-5.4$ . Now, 30% of this is $30%(b-5.4)=30%b-30%(5.4)$ .

This is also not the correct expression.

Therefore, only choice A is the correct justification of the given expression.
