Answer:
-2 = 4+x2
16 = -15 + y2
Step-by-step explanation:
xm, ym = (x1+x2)/2 , (y1+y2)/2
xm = (x1+x2)/2
ym = (y1+y2)/2
substitute in what we know
-1 = (4+x2)/2
8 = (-15+y2)/2
multiply each equation by 2
-2 = 4+x2
16 = -15 + y2
Answer:
There is a 2/3 probability that the other side is also black.
Step-by-step explanation:
Here let B1: Event of picking a card that has a black side
B2: Event of picking a card that has BOTH black side.
Now, by the CONDITIONAL PROBABILITY:

Now, as EXACTLY ONE CARD has both sides BLACK in three cards.
⇒ P (B1 ∩ B2) = 1 /3
Also, Out if total 6 sides of cards, 3 are BLACK from one side.
⇒ P (B1 ) = 3 /6 = 1/2
Putting these values in the formula, we get:

⇒ P (B2 / B1) = 2/3
Hence, there is a 2/3 probability that the other side is also black.
Answer:
<em>The amount to be paid is rupee 1872.72</em>
Step-by-step explanation:
<u>Compound Interest
</u>
It occurs when interest in the next period is earned on the principal sum plus previously accumulated interest.
The formula is:

Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
The initial amount is P=1800 at r=8% = 0.08 during t=6 months (t=0.5 years) compounded quarterly. There are 4 quarters in a year, thus n=4.
Calculating A:


A = 1872.72
The amount to be paid is rupee 1872.72
D because it is more simpler than just using a graph
