Find the average range. Round the mean and the average range to the nearest tenth. (Show all your work on scratch paper, then enter your answers below.) 3, 12, 15, 25, 30, 40

Answers

Answer 1

Answer: 3, 12, 15, 25, 30, 40The range is the difference between the greatest and smallest values:
range = 40 - 3 = 37

Thee average is the sum of elements divided by the number of elements:
average = (3 + 12 + 15 + 25 + 30 + 40)/6
average = 125/6 = 20.83

Answers

Answer: A is the 8-pack, B is the single roll, C is the 100 pack, D is the 50 pack.

Step-by-step explanation:

For each of these, multiply the smaller number by a number that has a product of the bigger number, example D. multiply 25 by 2 to get 50, then compare the totals.

Answer:

the first one is an 8 pack of glue sticks

the second one is 1 tape roll for .19

The derivative of the natural log is 1/x, therefore the derivative is 1/cos(x). However, since the value of cos(x) is submitted within the natural log we must use the chain rule. Then, we multiply 1/cos(x) by the derivative of cos(x). We get the answer: -sin(x)/cos(x) which can be simplified into -tan(x) i

A line crosses the y-axis at (0,4) and has a slope of -2. Find an equation for the this line.A) y = 2x + 4 B) y = -2x + 4 C) y = -2x - 4 D) y = -4x + 2 <-- 6)Write the equation of the line with the given slope and y-intercept.
slope = 5 y-intercept = 8 A) y = 5x + 8 B) x = 5y + 8 <-- C) y = 8x + 5 D) x = 8y + 5

A) y = 5x + 8

In the ordered pair (0,4), what does the 4 represent in terms of its location on the coordinate plane?

Answers

In this question because x is 0 you can say 4 is point of y or y-intercept
but if y was 0 then x was 4 so the point was x-intercept :)))

What is the product?

2x(x – 4)

Answers

Keywords:

Product, factors, polynomial, distributive property

For this case we must find the product of two factors of a polynomial. To do this, we must apply the distributive property, which states: $a (b + c) = ab + ac.$

So:

$2x (x - 4) = 2x * x-2x * 4\n2x (x - 4) = 2x ^ 2-8x$

Thus, the product of $2x (x - 4)$ is: $2x ^ 2-8x$

Answer:

The product of $2x (x - 4)$ is: $2x ^ 2-8x$

Answer:

The product of $2x(x- 4)=2x^2-8x$

Step-by-step explanation:

Given : Expression $2x(x-4)$

To find : The product of the expression

Solution :

To find the product of the expression we apply distributive property in this

Distributive property $a(b+c)=ab+ac$

Where a= 2x, b=x, c=-4

$2x(x- 4)=2x(x)+2x(-4)$

$2x(x-4)=2x^2-8x$

Therefore, The product of $2x(x-4)=2x^2-8x$
