Answer:

Step-by-step explanation:
we have given x'=(24-16)x=8x
x' denotes the differenation
differentiation is performed with respect to t
by variable separable method we can write

on integrating both side

(property of log )
so the solution for x will be 
The probability of multiple events happening is calculated by multiplying the probabilities of each event together. This is the case if each event is independent of the other events.
For a fair coin, the probability of tails is 1/ 2 or 0.5, so the probability of all tails in 10 tosess is (1/2)^10 = 1/1024 = 0.0009765625
Correct answer: D
Answer:
15 feets, 11.25 inches
Step-by-step explanation:
Given that:
Scale = 1 : 48
Thus means that the model is 1/48 the actual size of the jet
Length of fighter jet = 63feets, 9 inches
Converting the entire length to inches
1 feet = 12 inches
63 feets = (12 * 63) = 756
Lenght of jet = (756 + 9) = 765 inches
1/48 * 765 = 15.9375 ; 15 feets, 11.25 inches
Hence, length of model = 15 feets, 11.25 inches
