Answer:
Step-by-step explanation:
y=ax^2+bx+c
a parabola open down when a is negative
y intercept equal 3 when x=0 then y=c=3
vertical stretch : is a stretch away from the x-axis
the equation is (-0.5x^2+4x+3)

Answer:
The probability that the man is greater than 74 inches is 0.1587
Step-by-step explanation:
The required probability is found by evaluating the area under the corresponding distribution curve for the corresponding values
The standard normal variate factor (Z) is given by
where
is mean of the data
is the standard deviation of the data
Thus corresponding to x = 74 the Z factor equals
Using the standard normal distribution table corresponding to mean of 70 and deviation of 4 the area under the curve corresponding to Z = 1 equals
0.1587
