Answer:

70.6

Step-by-step explanation:

The mean is the average of a set of numbers.

To find it, add up all the terms and divide it by the number of terms.

70 + 67 + 79 + 66 + 64 + 80 + 64 + 75 = 565

565 / 8 = 70.625

Rounding this to the nearest tenth, we get an answer of 70.6

40/3 days, (13.33 days)

Step-by-step explanation:

Set up the equation, 15/20 = 10/x, and then use cross mutiply to solve it.

10 * 20 = 15x, x = 200/15 = 40/3

Which of the following is an example of the difference of two squares
True [87]

Complete Question: Which of the following is an example of the difference of two​ squares?

A x² − 9

B x³ − 9

C (x + 9)²

D (x − 9)²

Answer:

A. x^2 - 9.

Step-by-step explanation:

An easy way to spot an expression that is a difference of two squares is to note that the first term and the second term in the expression are both perfect squares. Both terms usually have the negative sign between them.

Thus, difference of two squares takes the following form: a^2 - b^2 = (a + b)(a - b).

a² and b² are perfect squares. Expanding (a + b)(a - b) will give us a^2 - b^2.

Therefore, an example of the difference of two squares, from the given options, is x^2 - 9.

x^2 - 9 can be factorised as x^2 - 3^2 = (x + 3)(x - 3).
