Estimated the difference 825 round subtract the rounded numbers 213 rounds to

boyakko [2]

Answer:

600

Step-by-step explanation:

Given,

Numbers are 825 and 213.

If the number are equal or greater than 50 then one number will be rounded up. if the number is less then it will rounded down.

Like in this case 25 and 13 are less than 50 so, they will not rounded up.

825 will be rounded to 800.

213 will be rounded to 200.

Subtraction of number

= 800 - 200 = 600

Find the mean and the standard deviation for each set of values. Show your work. 15,17,19,20,14,23,12

vekshin1

1. Mean.

$\overline{x}=\dfrac{15+17+19+20+14+23+12}{7}=\dfrac{120}{7}\approx\boxed{17.14}$

2. <span>Standard deviation.

First we have to square each value and calculate the mean of that squares:

$\overline{x^2}=\dfrac{15^2+17^2+19^2+20^2+14^2+23^2+12^2}{7}=\boxed{\dfrac{2144}{7}}$

so the variance:

$s^2=\overline{x^2}-\overline{x}^2=\dfrac{2144}{7}-\left(\dfrac{120}{7}\right)^2\approx\boxed{12.41}$

and the standard deviation:

$s=\sqrt{s^2}=\sqrt{12.41}\approx\boxed{3.52}$
