The answer, at least what I got, is 17.375 . They'd have to open an eighteenth package because the extra .375 is not in the original package, so I would go with B .
1 cm : 15 yd
Multiply this proportion by 5
5 cm : 75 yd
Multiply the original proportion by 8
8 cm : 120 yd
a) The dimensions of the field are 75 yd by 120 yd.
b) The area is (75 yd)*(120 yd) = 9000 yd^2.
The answer should be 32.25
Answer:
The standard deviation for the number of students who work full time = 8.38
Step-by-step explanation:
Given data
Sample size n = 284
No. of students work full time is P = 55 % = 0.55
No. of students who not work full time is Q = 100- 55 % = 45 % = 0.45
The standard deviation is given by

Put all the values in above equation we get

S.D. = 8.38
This is the standard deviation for the number of students who work full time.
