Any complex number 
can be written in trigonometric form as
where 
is the modulus of and 
is its argument, i.e. the angle makes with the positive real axis in the complex plane.
We have
and
Then
Answer: Statistic.
Step-by-step explanation: Statistic are used to refer to numerical measurement pertaining to a sample. A sample refers to a subset of members chosen from a population, which means a smaller representation of the larger group. Hence, in the scenario above, the population is the entire seniors which makes up the group. While the sample is the subset of seniors drawn from the whole. Hence, statistical measures calculated or derived from the sample is called statistic. Hence, the 25% obtained is a statistic.
Answer:
3x+10
Step-by-step explanation:
You start by changing the fraction into a decimal.
4.5 lb. of ground beef= 16.11
6.25 lb. of ground turkey= 18.50
Next, you divide the amount they cost by the pounds to get the price per pound.
16.11÷4.5= 3.58
18.50÷6.25= 2.96
So, a pound of beef is $3.58, and a pound of turkey is $2.96.
The turkey is 62 cents less than the beef per pound.
That means the turkey is a better buy! :)
(Have a good day! :))
Answer:
Ethan = 1.(3x)
Step-by-step explanation:
Let's split "Ethan saved 1/3 more than that"
That = x
So, Ethan saved 1/3 more than x
Meaning that Ethan = x + 1/3x
Combine like terms
Ethan = 1 1/3x
which equals to
Ethan = 1.(3x)
Hope this helps :)
Have a great day
