Answer:
144
Step-by-step explanation:
12x12=144
This is a great place and time to apply synthetic division. Since you are dividing the 3rd order poly by (a+2), let the divisor in synth. div. be -2.
Then:
_________________
-2 / 1 6 12 8
_____-2_-8 -8____________
1 4 4 0
Since there is no remainder, -2 is a root and (x+2) is a factor of the poly.
The quotient comes from those coefficinets 1 4 4
and is 1a^2 + 4a + 4, whose factors are (a+2)^2.
Answer:
(3138.29, 3705.11)
Step-by-step explanation:
Given that for sample size of n = 50 male athletes from eight Canadian sport centers surveyed, the average caloric intake was 3077.0 kilocalories/day with a sample standard deviation of 987.0.
The recommended amount = 3421.70
To construct 95% confidence interval
Since population std deviation is not known we use t critical value for degree of freedom 50-1 =49
t critical = 2.010
Hence margin of error = 
Confidence interval lower bound = 
Confidence interval upper bound = 
Conf interval =
