(2+2i)(5+3i)
10+6i+10i+6i^2
10+16i+6(-1)
4+16i
When you have an “i^2”, you also have a negative one. The simplified answer is 4+16i
Answer: Statements 2 and 3
Step-by-step explanation:
On a drawing scale;

7cm - 28m (multiplying by 7)
8cm - 32m (multiplying by 8)
9CM - 36M (MULTIPLYING BY 9)
Answer:
C. 30
Step-by-step explanation:
-It is a statistical rule of thumb that the size of a sample must be
.
-This size is deemed adequate for the Central Limit Theorem to hold.
-At this size or greater, the shape of the resultant distribution is normal.
#It should however be noted, that for a normal distribution the CLT holds even for smaller sample sizes.
Answer:
t=r/(sq)
Step-by-step explanation:
r=sqt
=> r/(sq)=t
