Answer:
a) 0.2778
b) 0.3611
c) 0.1389
d) 0.0833
Step-by-step explanation:
We have a total of 5 + 3 + 1 = 9 balls
a) First ball being yellow: we have 5 yellow balls, so P1 = 5/9
Second ball being yellow after one yellow was drawn: we have 4 yellows and 8 balls, so P2 = 4/8 = 1/2
Both yellows: P = P1 * P2 = 5/18 = 0.2778
b) Both blues:
P1 = 3/9 = 1/3
P2 = 2/8 = 1/4
P = P1 * P2 = 1/12 = 0.0833
Both yellows or both blues: 5/18 + 1/12 = 0.2778 + 0.0833 = 0.3611
c) First yellow: P1 = 5/9
Second red: P2 = 1/8
Pa = P1 * P2 = 5/72
or
First red: P3 = 1/9
Second yellow: P4 = 5/8
Pb = P3 * P4 = 5/72
P = Pa + Pb = 10/72 = 5/36 = 0.1389
d) First blue: P1 = 3/9 = 1/3
Second red: P2 = 1/8
Pa = P1 * P2 = 1/24
or
First red: P3 = 1/9
Second blue: P4 = 3/8
Pb = P3 * P4 = 1/24
P = Pa + Pb = 2/24 = 1/12 = 0.0833
Domain is the x-coordinate and range is the y - coordinate
Answer:
$5.35.
Step-by-step explanation:
The number of checks written after the first 10 = 24 - 10 = 14.
The fees for these checks = 14 * 0.10
= $1.40.
So his fees for March are 3.95 + 1.40
= $5.35.
C. they might miss realising that the first 10 checks are free.
Answer:
x = -2
Step-by-step explanation:
You have -5x + (-2) = -2x +4 add 5x on both sides and you will have
-2 = -2x + 5x +4 simplify
-2 = 3x + 4 add -4 on both sides
-2 -4 = 3x
3x = -6 divide both sides by 3
x = -2
