Find the mean of 65, 67, 69, 67, 63, 60,60

Answers

Answer:

64.428

Step-by-step explanation:

well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence

so if we add all of the numbers up it will give us

451

then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with

around 65 or exactly it would be

64.428

At a sale this week, a sofa is being sold for $272. This is a 36% discount from the original price. What is the original price?

Answers

Answer:

Step-by-step explanation:

A 36% discount means the selling price is (100-36)% = 64% of the original price.

$272 = 64% of x = 0.64·x

x = $272/0.64 = $425

What is 1102 using the polynomial identity (a+b)2=a2+2ab+b2 ?

Drag and drop the correct responses into the boxes.

Let the smaller value a = Response area and the larger value b = Response area. Then a2+2ab+b2 is Response area. This can be simplified to Response area. So, 1102 is equal to Response area.

Answers

Answer:

"Let the smaller value a = 10 and the larger value b = 100. Than a^2 + 2ab + b^2 is 10^2 + 2 * 10 * 100 + 100^2. This can be simplified to 12100. So, 110^2 is equal to 12100."

Hope this helped!

The smaller value is 10

The larger value is 100

So the square of 110 should be 12100

Calculation of the value:

Since here we assume the smaller value be 10

So, the larger value be 100

Now

[tex]a^2 + 2ab + b^2 = 10^2 + 2 \times 10 \times 100 + 100^2.[/tex]

This can be simplified to 12100.

So, [tex]110^2[/tex] is equal to 12100.

Solve w^2+13w+42=0 by factoring.

Answers

Answer: {-7, -6}

Explanation: When an equation has a squared term in it,

it's called a polynomial equation.

The rule for solving a polynomial equation

is to first set it equal to 0, then factor.

Since this equation is already set equal to 0, we can factor the left side.

The left side is a trinomial that can be

factored as the product of two binomials.

The first term in each binomial will be a factor of the w².

Since w² factors a w · w, we use a w as our first term.

For the last terms, we use factors of 42 that add

to 13 and these factors are +7 and +6.

So we have (w + 7)(w + 6) = 0.

So either w + 7 = 0 or w + 6 = 0.

Solving for w in each equation, we find that our solution set is {-7, -6}.

Answer:

x = - 5, x = - 1

Step-by-step explanation:

Given

(x + 3)² = 4 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 3 from both sides )

x = - 3 ± 2

Then

x = - 3 - 2 = - 5

x = - 3 + 2 = - 1
