Answer:
2
Step-by-step explanation:
To find slope you use the formula Y2-Y1/X2-X1, so it would be (9-3)/(5-2) which equals 6/3
You then reduce to get 2
The probability of picking a marble that is not blue is 5/6
The proportions of the balls are given as:
The probability of picking a ball that is not blue is:
So, we have:
Rewrite the fractions as equivalent fractions
Take LCM
Add 3 and 2
Hence, the probability of picking a marble that is not blue is 5/6

You would solve that as 850/680, which is 1.25, therefore 125%
Answer:
20
Step-by-step explanation:
Answer: DA = 6
====================================================
Explanation:
The triangles are similar, allowing us to make the proportion below
DB/DA = DA/DC
Plug in the given values. Cross multiply and solve for x
DB/DA = DA/DC
9/DA = DA/4
9*4 = (DA)*(DA)
36 = (DA)^2
(DA)^2 = 36
DA = sqrt(36)
DA = 6
The length of DA is exactly the geometric mean of the lengths BD and DC
geometric mean of x and y = sqrt(x*y)
