victus00 [196]

Answer:

{A and B are independent events}, P(A|B)=P(A)=0.16

Step-by-step explanation:

First of all we need to know when does two events become independent:

For the two events to be independent, P(A|B)=P(A) that is if condition on one does not effect the probability of other event.

Here, in our case the only option that satisfies the condition for the events to be independent is P(A|B)=P(A)=0.16.. Rest are not in accordance with the definition of independent events.

Please help me in the question of commission ! Grade - 9 .

AlladinOne [14]

Answer:

Step-by-step explanation:

Commission for amount Rs. 5,00,00 = $\frac{2}{100}*500000$

= 2* 5000

= Rs. 10,000

total commission = Rs. 32,000

Remaining commission = 32500 - 10000

= Rs. 22500

Let remaining amount of the restaurant = Rs. x

Commission on Rs. x = 22500

3% of x = 22500

$\frac{3}{100}*x=22500\\\\x=22500*\frac{100}{3}\\\\x = 7500*100$

x = Rs. 750000

Price of the restaurant = 750000 + 500000

=Rs . 1250000

Andy watches 10 television shows every week. He watches dramas, comedies, and reality shows. Dramas are 1 hour long, comedies ar

Lunna [17]

Answer:

$d+0.5c+2r=8\\\\ c=2d$

Step-by-step explanation:

Let d= dramas

c= comedies

r= reality shows

Dramas are 1 hour long, comedies are 30 minutes, and reality shows are 2 hours long.

Total time spent on watching = $1 \times(d) + 0.5 \times (c) +2 \times(r)= d+0.5c+2r$

[ $30\ minutes=\dfrac{30}{60} \ hours = 0.5 hour \ \ (1 hour = 60\ minutes)$ ]

Since he spent 8 hours for this, that means

$d+0.5c+2r=8$ → First equation

He watches twice as many comedies as dramas.

i.e. $c=2d$ → second equation

So, the system of equations could be used to determine how many of each type of show he watches each week:

$d+0.5c+2r=8\\\\ c=2d$
