Answer:
the expected value is if your sum is odd because half of the values you could roll are odd witch means you have 50% chance to get odd
because their are not high odds of getting something good
Answer:
if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.
We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.
Then draw a vertical line for your stem hopefully it is on lined paper.
single digits 1-9 go right side.
tenths get split keeping digits rights side
hundred units get split keeping tenth and single digits right side
and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.
Larger numbers that have 3 digits are more than double digits I've called 100th units
Numbers lower than 9 will be on rights side on the first line.
1-9 = 0 | 1 2 3 4 5 6 7 8 9
10-19 1 | 0 1 2 3 4 5 6 7 8 9
20-29 2| 0 1 2 3 4 5 6 7 8 9
100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line
We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.

Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode
Answer:
67
Step-by-step explanation: 67 is 100% of itself duh
Answer:
Step-by-step explanation:
First you need to put the equation in slope intercept form.
y = mx + b (m = slope and b = y-intercept)
5x + 2y = 12 (subtract 5x)
2y = -5x + 12 (now you need to isolate y. Therefore, divide all by 2)
y = -5/2x + 6
Now you have your slope and y-intercept. Your y-intercept will be 6. So on the graph you need to begin at 6 on the y-axis <em>(the line that goes up and down)</em>. Make your first point there. Your slope is the -5/2x. Slope is looked at as rise/run. This means from your point at 6, you will go down <em>(down because it's negative. If it was a positive, you would go up, i.e rise)</em> 5 units. Then you will go over to the right 2 units <em>(to the right because it is positive. Only the top one will be negative.)</em> Place your point once you have done that. Then draw a line between those two points.
<u>(note that on my screenshot, the tiny squares do </u><u>not</u><u> equal 1 unit. The larger ones with the bunch of tiny squares inside equal 1 unit)</u>
I hope this helped :)
