Answer:
Step-by-step explanation:
There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.
Answer:
8?
Step-by-step explanation:
I'm not sure what the answers are, but I can help. If you go to the x axis and search for 50, then go straight up to the line of best fit, you'll find the estimated height of the tree. It appears to be about 70.
Hope this helps!
The slope would be 0 because if you put in the coordinates with the formula, you would get the slope as 0. This also makes sense because both points have the same y point, so that means that the line wasn’t travelling up or down. And since it was only going through -8 that would be the y-intercept.
A*5+b*2=145
a +b =50 | * -2
5a +2b=145
-2a -2b = -100
----------------------
5a-2a = 145-100
3a= 45
a=45:3
a=15 questions are worth 5 p
b=50-15=35 questions worth 2 p
