Answer:
he could have five 20 bills at most
First Solving for like terms such as 2x+-4x = -2
Answer:
d. 1/16
why does the answer neeeds to be 20 characters long?!
The final probability is the weighted average of the playing probabilities calculated over the possible weather options:
P(john practices cello; given that it rains) * P(it rains) +
P(john practices cello; given that it does not rain) * P(it does not rain) =
0.6 * 0.7 + 0.4 * 0.3 = 0.54
The probability is 54%
EF ( x1=0, y1=1), (x2=3, y2=3)
JK (x1=8, y1=2), (x2=6, y2=5)
Slope of a line=(y2-y1)/(x2-x1)
Slope of EF =( 3-1)/(3-0)= 2/3
Slope of JK =(5-2)/(6-8)= 3/-2
Since the slopes of those lines are negative reciprocal the lines are perpendicular
Line EF is perpendicular to JK
