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: 20%
Step-by-step explanation:
(part / whole) * 100
(3 / 15) * 100 = 20%
Answer:
36 riders in 16 minutes, 54 riders in 24 minutes, and 72 riders in 32 minutes.
Step-by-step explanation:
The roller coaster can accommodate 9 riders every 4 minutes. 36 riders in 16 minutes, 54 riders in 24 minutes, and 72 riders in 32 minutes all follow the common ratio.
60 degrees, because it's an equilateral triangle, as you can tell because the sides are all the same length.
Answer:
I hope this helps!
Step-by-step explanation:
1. M is .25
b is 20
so
y= .25x+20
2. y= 3x+2
