Step-by-step explanation:
that should be right
Answer:
it's A because all of those numbers are less than 14
Step-by-step explanation:
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Mean = 70 inches
Standard deviation = 3 inches
Average basket ball player = 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,
At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.
Direct proportionality is the type of proportionality where an increase in one quantity or variable causes a corresponding increase in another quantity.
Therefore; y varies directly as x
Hence; y α x
y =k x where k is a constant
if y= 28 and x = 7 , then k = 28/4 =4
hence, y = 4 k
when x = 4, then y= 16
