Okay so the range is the largest number - the smallest number.

So 25 - 11 = 14

The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.

So we first calculate the mean.

119 ÷ 7 = 17

Now we calculate the distance each value is from 17. (SEE ATTACHMENT)

What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.

28 ÷ 7 = 4

The Absolute Mean Deviation is 4.

I'll figure out the bottom in a minute. But this is all I got for you so far.

1.) The sum(addition) of 21 and 5 times(multiplication) a number f is(=) 61.

f = unknown number/variable [So 21 plus 5f(5 times f) equals 61]

21 + 5f = 61 [21(one-time) + 5f(number x variable) = 61(total)]

2.) Seventeen more(addition) than seven times(multiplication) a number j is(=) 87.

j = unknown number/variable [So 17 plus 7j(7 times j) equals 87]

17 + 7j = 87

3.) n = number of calls

18 + 0.05n = 50.50

[Company charges $18 plus five cents per call(n), and the total charge was $50.50]

4.) s = the number of students

40 + 30s = 220

[Tutor charges $40 plus $30 per student(s), and the total charge was $220]

A circle whose center is the origin passes through the point (-5,12). Which point also lies on this circle?

schepotkina [342]

The answer is B(11, 2sqrt(12) )
proof

the main equation of the circle is (x-x1)²+(y-y1)²=R²
where C(x1, y1) is the center
so if the center is the origin, it is O(0,0), and the equation becomes
<span> (x)²+(y)²=R²
</span>and the circle passes through the point (-5,2) so we can write
(-5)²+12²=R², it implies R= sqrt(25+144)=sqrt(169)=13

and for <span>B(11, 2sqrt(12) ) </span>11²+ (2sqrt(12))²= 121 + 48= 169= 13
it is checked.

Rewrite these in increasing order of length:<br> 133 dm. 433 cm, 308 km, 91 mm

Oksi-84 [34.3K]

$\boxed{91mm$

<h2>Explanation:</h2>

First of all, let's transform each measurement into meter knowing the following relationships:

$1dm=0.1m \\ \\ 1cm=0.01m \\ \\ 1km=1000 m \\ \\ 1mm=0.001m$

Therefore, we can compute the following:

$\bullet \ 133dm \rightarrow 133dm(\frac{0.1m}{1dm})=13.3m \\ \\ \bullet \ 433cm \rightarrow 433cm(\frac{0.01m}{1cm})=4.33m \\ \\ \bullet \ 308km \rightarrow 308km(\frac{1000m}{1km})=308,000m \\ \\ \bullet \ 91mm \rightarrow 91mm(\frac{0.001m}{1mm})=0.091m$

Writing this in increasing order:

$0.091m$
