It is -7/2 when the variables are substituted
R = Rate of gasoline by automobile = 35 mi/gal
it is given that , 1 kilometer = 0.6214 miles
and 1 gallon = 3.78 liter
so
R = 35 (miles/gallon) (1 kilometer/0.6214 miles) (1 gallon/3.78 liter)
R = (35) (1/0.6214) (1/3.78) (miles x 1 kilometer/1 miles) (1 gallon/(1 gallon x 1 liter))
R = 14.9 kilometer/liter
Answer:
Step-by-step explanation:
Let x be a random variable representing the flight arrival time from Boston to New York.
For a uniform probability distribution, the notation is
X U(a, b) where a is the lowest value of x and b is the lowest value of x
The probability density function, f(x) = 1/(b - a)
Mean, µ = (a + b)/2
Standard deviation, σ = √(b - a)²/12
From the information given, the time difference in minutes is 9:57 - 9:07 = 50 minutes. Therefore,
a = 0
b = 50
µ = (0 + 50)/2 = 25
σ = √(50 - 0)²/12 = 14.43
b) converting to minutes, it is 9:30 - 9:07 = 23 minutes
the probability that a flight arrives late(later than 9:30 am) is expressed as P(x > 23)
f(x) = 1/(50) = 0.02
P(x > 23) = (50 - 23)0.02 = 0.54
Answer and Step-by-step explanation:
Area (A) = 153
Length (l) = 8 + w
Width (w) = w
A = lw
153 = (8 + w)(w)
153 = 
0 = - 153
(w - 9)(w + 17)
w = 9
w = -17
We can't have a negative length, so we only use 9.
w equals 9.
That means l equals 17 (9 + 8 = 17).
Length = 17
Width = 9
