It’s rational because the square root of 0.49 is 0.7
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
Answer:
-14/1-5x
Step-by-step explanation:
Let x be the number of households with TV.
So .68x would be the number of households with cable.
If 8000 were added to the above number, it would be equal to 67,600,000.
Thus we have our equation:
.68x + 8000 = 67600000
Solving for x:
.68x = 67592000
x = 99,400,000
Answer:
3) 0.30
The probability a randomly selected<em> student plays a sport</em> given they work part time = 0.30
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given 'A' plays a sport
B work part time
Given P(A) = 0.48
P(B) = 0.40
P(A∩B) =0.12
P(A∪B)¹ =0.24
<u><em>Step(ii)</em></u>:-
By using conditional probability

and similarly 
The probability a randomly selected<em> student plays a sport</em> given they work part time
Now 

<u>Final answer</u>:-
The probability a randomly selected<em> student plays a sport</em> given they work part time = 0.30
