Answer: False.
Step-by-step explanation:
For any random variable x,
Formula to calculate the z-score : 
, where 
= Mean
= Standard deviation
Let x be the data point has a corresponding z-score of -1.5.
Then , we have
i.e. x is one and a half standard deviations below the mean value.
( one and a half =
)
Therefore , the given statement is false.

Answer:
D: {9, 21, 33}
Step-by-step explanation:
Ken worked 2, 8 and 14 hours on 3 separate days.
For working 2 hours, his earnings were f(2) = 2(2) + 5, or 9;
For working 8 hours, his earnings were f(28) = 2(8) + 5, or 21; and
For working 14 hours, his earnings were f(14) = 2(14) + 5, or 33
Thus, the range of this function for the days given is {9, 21, 33} (Answer D)
Answer:
Volume of cone = 234.45 cm³
Step-by-step explanation:
Given:
Diameter = 8 cm
Radius r = 8 / 2 = 4 cm
Height h = 14 cm
Find:
Volume of cone
Computation:
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)(3.14)(4)²(14)
Volume of cone = 234.45 cm³
It is $69 because if every time you withdraw money you get $3 and you took $20 out 3 times that 20x3 is 60 and then plus $3x3 is nine add it all together it is $69
