Answer:
1109
Step-by-step explanation:
The first term is -27, and the common difference is 16.
The nth term is:
a = a₁ + d (n − 1)
a = -27 + 16 (n − 1)
a = -27 + 16n − 16
a = 16n − 43
The 72nd term is:
a = 16(72) − 43
a = 1109
Answer:

Answer: 385
Given: error: 6 months, standard deviation = 5 years is 60 months
Step 1: find the minimal sample size ‘n’ for 95% confidence interval
1-0.95= 0.05
0.05/2= 0.025
Step 2:
1-0.025= 0.975

ANSWER
The algebraic expression that is a polynomial with a degree of 2 is
EXPLANATION
The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.
The highest degree of the polynomial is considered the degree of the polynomial.
For first option,
the highest degree is 3.
The second option is,
This polynomial also has a degree of 3.
The third option is,
This last option has a degree of 2.
Therefore the correct answer is option C.
Answer: 4x² -4
Step-by-step explanation:
First, evaluate the exponent you'll get, + 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms, -4 +4x² turns into, 4x² -4!
