Subtract 3 first so it would be 7x=15
then divide by 7 so x would be approximately 2.14
Answer:
A=266CM
Step-by-step explanation:
p=2l + 2w l=2x+1 w=x+5
66=2[2x+1] + 2{x+5] l=2x9 + 1 w=9+5
66=4x+2 + 2x+10 l=18+1 w=14
66=6x+12 l=19
66-12=6x
54=6x A=L x W
x=9 A=19 x 14
A=266CM
Answer:
1) a) 0.8
b) 0.6
2) a) 0.08
b) 0.14
Step-by-step explanation:
1) Given
and 
Let us learn about a formula:

(a) If A and B are mutually exclusive i.e. no common thing in the two events.
In other words:
=
= 0
Using above formula:

(b) P(A and B) = 0.2
Using above formula:

Let us learn about a formula:
for dependent events
for independent events.
(a) If A and B are independent events :
Using the above formula for independent events:

(b) 
Using above formula:
