Answer:

The Range is the amount between the largest and smallest numbers. Or as said here, "The distance between the smallest and largest value. "

The Mean is a fancy word meaning (no pun intended) the average of all numbers listed. Or as said here, "The average of all values."

So, the second answer selected and third answer selected are correct.

Answer:

The Range (Statistics) The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Drew has more than 4 times as many baseball cards as mark. Katie has fewer than half as many cards as mark. Mark has m baseball

Sphinxa [80]

Answer:

Cards with Mark = 30

Cards with Drew = 120

Cards with Katie = 12

Step-by-step explanation:

The complete question is

Drew has 4 times as many baseball cards as Mark. Katie has 3 fewer than than half as many cards as Mark. In all they have 162 baseball cards. How many does each have?

Solution -

Let the number of cards with Mark be "X"

Number of cards with Drew = 4 *X = 4X

Number of Cards with Katies = 0.5 X -3

Sum of all the cards is equal to 162

X+4X + 0.5 X -3 = 162

5.5 X = 165

X = 30

Cards with Mark = 30

Cards with Drew = 4 * 30 = 120

Cards with Katei = 15-3 = 12

What is the most abundant gas in the Earth's atmosphere?

butalik [34]

Answer:

Nitrogen

Step-by-step explanation:

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases. Hope this helped!

Annual fixed costs for a product are $75,000. The product itself sells for $6 and it costs $2 in variable costs to make each pro

rusak2 [61]

Given

Annual fixed costs for a product are $75,000.

The product i sells for $6

it costs $2 in variable costs to make each product.

the variable cost per unit goes up to $2.50

find out how many units will the annual break-even point for the product change .

To proof

FORMULA

Break even = Fixed cost ÷ Contribution margin per unit

where

Contribution margin per unit = sale price - variable price

Take two cases

Case first

fixed costs for a product = $75,000

product itself sells = $6

variable costs = $2

put all the value in the above equation

we get

Contribution margin per unit = 6 - 2

= 4

$Break even (say B1 ) = \frac{75000}{4}$

= 18750 units

CASE SECOND

the variable cost per unit goes up to $2.50

put value inthe formula

Contribution margin per unit = 6 - 2.50

= 3.5

$Break even (say B2 ) = \frac{75000}{3.5}$

we get

Breakeven (sayB2) = 21428.6 unit

change in the break even product = B2- B1

= 21428.6 - 18750

= 2678.6 unit

Hence proved
