Answer:
Yes
Step-by-step explanation:
The slope intercept form is y=1.38x
The are 4 different possibilities to draw a ten, namely a ten of the four different suits. The probability of the event is the ratio of the 4 possibilities and the total number of possible choices, whcih is 52:
P(E) = 4/52 = 1/13 or about 7.7%
800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
