Answer:
I think you have it right. the quantity in column a is greater
Yes choice D is the correct answer. Nice job.
If you wanted, you can simplify the linear approximation L(x)
L(x) = f(a) + (x-a)*f'(a)
L(x) = f(-0.5) + (x-(-0.5))*f'(-0.5)
L(x) = 2 + (x+0.5)*4
L(x) = 2+4x+2
L(x) = 4x+4
Then plug in x = 0
L(x) = 4x+4
L(0) = 4(0)+4
L(0) = 4
But your method is a shorter route.
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.

Step-by-step explanation:
Answer:She will donate 18 dolls.
Step-by-step explanation:
She decided she wants to donate 30% of her dolls to an orphanage to others who will enjoy them. Total number of dolls that Alex was having was 60. She wants to donate 30% of 60 dolls. 30% of 60 dolls is determined by dividing 30 by 100 and multiplying the result by 60. It becomes
30/100 × 60/= 0.3 × 60 = 18 dolls
