Answer:
1) Event A = 2/3
Event B = 1/2
2) 1/2
Step-by-step explanation:
1)
Event A :
No. we need on dice = 4
Total numbers on dice = 6
Hence sample space of the event = 6
P( getting 4) = 4/6 = 2/3
Event B :
A coin has a head & a tail.
Hence sample space of the event = 2
But as we need tail only ,
P ( getting Tail ) = 1/2 [ if only tossed once ]
2)
Total numbers on a die = 6
Total no. of odd numbers on die = 3 (∵ 1 , 3 & 5 are odd )
Sample space of this event = 6
P (getting an odd number) = 3/6 = 1/2
Answer:
They are opposites and parallel.
Step-by-step explanation:
The formula for exponential decay is
where a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 . 2018-2012 = 6 years)
<span>y </span>≈ <span>13351.62</span>
Answer:
8x + 3
Step-by-step explanation:
=5x+−7+3x+10
=(5x+3x)+(−7+10)
=8x+3
The sequence is 11n+1 as the difference between each number is 11 and if you substitute 1 for n, you must add 1 to 11 to make 12. This sequence works for the other numbers as well.
To find out the height of the plant on the 15th day, just substitute 15 for n:
(11 x 15)+1=166mm is the height of the plant in 15 days.
