We need to convert 45 min to hours.
There are 60 min in an hour.
45/60 = 0.75
45 minutes = 0.75 hour
(4 km)/(0.75 h) = 5.3333 km/h = 5 1/3 km/h
Answer: 5/14
--------------------------------------------------
Explanation:
A = event of drawing a blue card on the first selection
B = event of drawing a blue card on the second selection
P(A) = probability of drawing a blue card on the first selection
P(A) = (number of blue cards)/(number of cards total)
P(A) = 5/8
P(B|A) = probability of getting a second blue card GIVEN the first card is blue
P(B|A) = (number of blue cards left after event A happens)/(number of cards left)
P(B|A) = 4/7
The fact that B depends on A is very important. This happens because the first card is not replaced
Multiply the fractions
P(A)*P(B|A) = (5/8)*(4/7)
P(A)*P(B|A) = (5*4)/(8*7)
P(A)*P(B|A) = 20/56
P(A)*P(B|A) = 5/14
Which is why the answer is the fraction 5/14
Answer:
yyyyyyyyyyyyyyydilligaf
Step-by-step explanation:
5x^2+6=f(x)
and your graph plug that equation into an graph creator and it will automaticlly make your graph
2>8-4h/3 subtract 8 from both sides
-6>-4h/3 multiply both sides by 3
-18>-4h divide both sides by -4 (and reverse sign because of division by a negative value)
4.5<h or by convention...
h>4.5
