Answer:
0.714
Step-by-step explanation:
Argument
The total number of cards = 5 yellow. 3 blue and 7 red = 15 cards in all.
The probability of choosing a yellow card first is 5/15 = 1/3.
We are now down to 14 cards
There are 3 blue cards.
P(yellow then blue) = 1/3 * 3/14
P(yellow then blue) = 1/14 = 0.0714
Answer:
x = 5/2 = 2.5
Step-by-step explanation:
Given
f(x) = 3x-7
g(x) = x+2
g^(-1)(x) = f(x)
First find g^(-1)(x) = h(x)
x=h(x)+2
h(x) = x -2
h(x) = x - 2 = f(x) = 3x-7
solve for x
x-2 = 3x -7
-2 + 7 = 3x - x
2x = 5
x = 5/2

Answer:
7650 W-h
Step-by-step explanation:
1 day = 24 hrs
4 days and 6 hours = 4(24) + 6 = 102 hours
given
24 hrs (i.e 1 day) ------> consumes 1800 W-h
1 hour ------> consumes 1800/ 24 = 75 W-h
102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
