Answer:

Step-by-step explanation:

The finite set is  in which we can count the elements which has finite number of elements

option 1 is not correct because we can not count the whole numbers they could extended upto infinite.

Option 2 is correct that is finite because condition is given that is natural numbers less than 100,000.

Option 3 is finite because we can count all letters of the alphabet.

Option 4 is not finite because all odd numbers can be extended upto infinity.

Option 5 is correct that is finite because world's population will be a finite number.

Option 6 is finite because it is empty set which is finite.

You have money in your wallet, but you don't know the exact amount. When a friend asks you, you say that you have 100 dollars gi
Flauer [41]

Answer: 75 < x < 125.

Step-by-step explanation:

Let x be the amount of money in your wallet.  

The phrase "100 dollars give or take 25" means wallet can have money between (100-25) dollars and (100+25) dollars.

i.e. 100-25 < x < 100+25

⇒ 75 < x < 125.

That means the amount of money in your wallet lies between 75 dollars and 125 dollars.

Hence, the inequality to describe the amount of money in your wallet is 75 < x < 125.

The graph shows the relationship between the amount of milk and water used in a recipe
SpyIntel [72]

Answer:

Multiply the amount of milk by 4

Step-by-step explanation:

Given

See attachment for graph

Required

The rule of the graph

Pick any two points on the graph

(x_1,y_1) = (0,0)

(x_2,y_2) = (1,4)

Calculate slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{4 - 0}{1 - 0}

m = \frac{4}{1}

m =4

The graph equation is:

y = m(x - x_1) + y_1

y = 4(x - 0) + 0

y = 4(x)

y = 4x

<em>The above shows that the x values are multiplied by 4 to get y</em>

Robert stands atop a 1,380-foot hill. He climbs down, reaching the bottom of the hill in 30 minutes. What is Robert’s average ra
VLD [36.1K]
Before we calculate we can use some common sence thinknig to narrow down the choices. We know that Robert is gonig DOWN the hill, so it doesnt make sence that he woudl have a positive rate of change (i.e. the number feet up the hill he is is decreasing, not increasing) So right away, A & B are clearly wrong.

If we look at the last two (C & D) we can see that if -460 were right after 10 minutes he would have walked down 4,600 feet. This is WAY more that the total height of the hill and so can't be correct.

So C must be correct.

We can check this with some simple math:
rate = \frac{end-start}{time} = \frac{0ft-1380ft}{30mins}= -46\frac{ft}{min}
