Part A
P(white) = (3 white)/(10 total) = 3/10
<h3>Answer: 3/10</h3>
==============================================
Part B
10 total, 3 are white
10-3 = 7 are not white so they are either black or red
P(black or red) = 7/10
<h3>Answer: 7/10</h3>
==============================================
Part C
Earlier in part B we calculated 7 beads that weren't white
This means P(not white) = P(black or red) = 7/10
They are the same probability just phrased slightly different ways.
<h3>Answer: 7/10</h3>
==============================================
Part D
There aren't any blue beads (unless there's a typo somewhere). So the probability of picking not blue is 100% or we represent this as the value 1.
<h3>Answer: 1</h3>
Answer:
y=(7±√89)/-4
Step-by-step explanation:
y=(-b±√b^2 -4ac)/2a
Rewrite given equation in quadratic form so it is -2y-7y+5=0
Then, in formula, sub -2 for a, -7 for b, and 5 for c
y=-(-7)±√(-7)^2 -4(-2)(5)/2(-2)
When you multiply that out you get
7±√49-(-40)/-4
The next step is the answer given above
If you need the answer not in sq rt form, it is y=-4.1085 and y=0.0608
