12 times because you divide 60 by 5 and get 12.

Simplify the exoression (x^3-5x^2+7x-12)÷(x-4)<br>

kiruha [24]

Answer:

x^2-x+3

Step-by-step explanation:

You factor it out which would then make it

(x-4)(x^2-x+3)/x-4

Then you cancel out the common factor, x-4

which leaves you with x^2-x+3

Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:

Roman55 [17]

The confidence interval can be calculated from the margin of error, and vice versa,

The margin of error of the confidence interval is 2.156

The confidence interval is given as:

$\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}$

The formula of confidence interval is:

$\mathbf{CI = \bar x\pm E}$

Where E represents the margin of error.

So, by comparison:

$\mathbf{E = 1.96 \cdot 1.1}$

Multiply

$\mathbf{E = 2.156}$

Hence, the margin of error of the confidence interval is 2.156

Un numero entero y racional

mihalych1998 [28]

Answer:

Los números racionales son aquellos números que pueden ser expresados como una relación entre dos enteros. Por ejemplo, las fracciones 1/3 y –1111/8 ambas son números racionales. Todos los enteros están incluídos en los números racionales, ya que cualquier entero z puede ser escrito como la relación z /1.
