Answer:
15/56
Step-by-step explanation:
5 people have a license
3 people don't
? = Probability that first person has a license and second does not
We can divide the problem into two sections, the first being the probability of the first person having a license, and the second section is the probability that the second person doesn't have a license.
P1 = Probability of the first person having a license, there are 5 out of 8 person having a license, thus P1 = 5/8.
P2 = Probability of the second person having a license. There are 3 people not having a license, out of 8-1 = 7 persons available, since one is taken already from the first choice, therefore P2 = 3/7.
P1 and P2 are dependent events, thus P(1,2) = P1 * P2.
P(1,2) = P1 * P1 = 5/8 * 3/7 = 15/56
As per the problem,
Rhonda bought a new laptop for $800.
The laptop depreciates, or loses, 20% of its value each year.
The value of the laptop at a later time can be found using the formula
Here we have
P=$800
r=20%=0.20
t=2 years
Substitute the values in equation (1) we get
The laptop be worth in two years will be $512.
Answer:
x = 10
Step-by-step explanation:
We know that is a right angle which is 90 degrees.
we know one angle is 30 degrees.
So take 90- 30 = 60
now we solve for 6x
6*10 = 60 and 60+30=90
x = 10
Area= base x height
So, the base is 9 1/4 and the height is 18 feet
so, the Area= 9 1/4 x 18
9 1/4 x 18
= 166.5
