Answer:
Step-by-step explanation:
P(a or b) = P(a) + P(b) - P(a and b)
0.88 = 0.70 + 0.60 - P(a and b)
P(a and b) = 1.30 - 0.88 = 0.42.
So the events a and b are not mutually exclusive.
Answer:
4,331.25 in interest
Step-by-step explanation:
22,500.00x3.5%=787.50x5.5=4,331.25
22,500.00+4,331.25=26,831.25 total loan
E^(xy) = 2
(xdy/dx + y)e^(xy) = 0
At point (1, ln2), dy/dx + ln2 = 0
dy/dx = -ln2
Answer:
1.83 hours
Step-by-step explanation:
Time is inversely proportional to speed
Implies that T = k/R, where k is the constant of proportionality
Thus, the product T × R is a constant for any given valued of R,T.
Hence, 3 × 14 = t × 23
t = (3×14) ÷ 23
t = 1.83 hours
