Answer:
B
Step-by-step explanation:
Using the exact values
cos150° = - cos30° = - 
sin150° = sin30° = 
Given
z = 4(cos150° + isin150° ) , substitute values
= 4(- + i )
= - 2
+ 2i , that is
(- 2, 2 ) → B
Answer:
90.7 > 9.008
Step-by-step explanation:
The answer to that question is Random Sampling
Answer:
principal (p)=$35000
time(t)=8years
rate ( r)=7%
Step-by-step explanation:
- compounded amount(c.a)=p((1+r/100)^t )=$35000((1+7/100)^8)=$60136.5
- compound interest gain=$60136.5-$35000=$25136.5
- Karl gain interest in 1 year=$35000((1+7/100)-1)=$2450
- gain % in 1 year=$2450/$25136.5×100%=9.74%
Answer:
Step-by-step explanation:
If the mean is 110, and the standard devaition is 22,
1 standard dev. below the mean is 110-22
2 standard dev below the mean is 110-22-22
3 standard dev below the mean is 110-22-22-22
Hope that helps!
