I wrote it out on paper and uploaded the answer for you. Let me know if you have any questions.
blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%

Answer:
y = -0.25x + 10
Step-by-step explanation:
Point-slope form is y - y1 = m (x - x1)
Here, y1 is 7, m is -0.25, and x1 is 12
When you plug these values in, you get y - 7 = -0.25 (x - 12)
Now we have to solve for y.
y - 7 = -0.25 (x - 12)
Distribute
y - 7 = -0.25x + 3
Add 7 to both sides
y = -0.25x + 10
#1: The whole value of data is 21.
There are 21 data values on the dot plot.
#2: The number of data values is 14.
#3: The unit is: 21 ÷ 14.
And it is 1.5.
#4: A statistical question can be answered by collecting data and where there will be variability in that data.
For example, how many students enjoy playing game?
