Let X be a random sample representing the score of a student in the American Chemical Society Examination.
P(450 < x < 500) = P((450 - 500)/(90/sqrt(25)) < z < (500 - 500)/(90/sqrt(25))) = P(-2.778 < z < 0) = P(z < 0) - P(z < -2.778) = P(z < 0) - [1 - P(z < 2.778)] = P(z < 0) + P(z < 2.778) - 1 = 0.5 + 0.99727 - 1 = 0.49727 = 49.7%
x + 5 and 4x^2
Multiply the exponent of x by 2giving
The answer is
x^2 evaluates to
Multiply a and 5
Multiply a and 1
The a just gets copied along.
The answer is a
a
5*a evaluates to 5a

Answer:
The formula of speed :-
Speed = Distance/Time
Given distance = 10m
Time = 40s
Speed = 10/40
= 1/4
= 0.25m/s
