X = kpm/y where k is a constant
x=2,y=4,p=0.5, m=2 so:-
2 = k*0.5*2 / 4
2 = 0.25k
k = 2/0.25 = 8
required equation is x = 8pm/y
if the number of times spun is not a multiple of 8, it is impossible to land on an exactly even distribution for this spinner. But since the probabilities of landing on an exactly even distribution are so small, that detail doesn't perturb the overall trend, except perhaps down at n=8 spins So group 3
Answer:19.74 gallons of the gas in the tank is wasted.
Step-by-step explanation:
Since the efficiency of the gas engine is 6%, wastage is #= 100 - 6 = 94%.
Therefore wastage = 94% x 21=94 x21/100=19.74 gallons
Answer:
The domain of the function is the interval [0,2.23]
see the explanation
Step-by-step explanation:
Let
t ----> the time in seconds
h(t) ----> the height of the laptop in units
we have

we know that
When the laptop hits the ground, the value of h(t) is equal to zero
so
For h(t)=0

Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
---> is not a solution
therefore
The domain of the function is the interval [0,2.23]
All real numbers greater than or equal to 0 seconds and less than or equal to 2.23 seconds
