Answer:

82 (B)

Step-by-step explanation:

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). To find the median, all you have to do is list down, in a row, all the numbers. Then scratch off the first and last number and keep doing that. not sure how to explain it, but like this.  64,67,70,70,70,73,76,79,79,82,82,85,88,91,94,94,97,97,100,100,100

the number left in the middle, as you can see, is 82.

Andreas93 [3]

Answer:

<em>x = -11</em>

Step-by-step explanation:

<u>Equations</u>

The image shows a right triangle with angles 70°, 90°, and x+31.

The sum of the internal angles of a triangle is 180°, thus:

70 + 90 + x + 31 = 180

Simplifying:

191 + x = 180

Subtracting 191:

x = 180 - 191

x = -11

Please simplify this n - 10 + 9n - 3
Dvinal [7]

Answer:

10n - 13

Step-by-step explanation:

All you have to do is combine the numbers/variables alike.

n + 9n (It's addition because the 9 is positive) = 10n

-10 - 3 (It's a negative minus 3 because it's subtraction 10 and 3) = -13

Now you just have to combine the two (The variable(s) ALWAYS go first, generally in alphabetical order)

10n - 13

And there's your answer!

algol [13]

Answer:

-1.53

0.47

-2.07

2.65

The last two observations are unusual

Step-by-step explanation:

mathematically;

z-score =( x-mean)/SD

Kindly note that an observation is termed unusual if the z-score is greater than +2 or less than -2

for x= 13

z-score = (13-21.4)/5.5 = -1.53

for x= 24

z-score= (24-21.4)/5.5 = 0.47

for x = 10

z-score = (10-21.4)/5.5 = -2.07

unusual

for x = 36

z-score = (36-21.4)/5.5 = 2.65

unusual
