Answer:
#19 is C
# 20 is True, False, and False
Step-by-step explanation:
Answer:
The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: 
Step-by-step explanation:
We need to determine the value of c that will result in a perfect square trinomial.
Perfect square trinomial are of form: 
Now, the equation given is:
Looking at the term 6w, we can write it as 2(w)(3)
We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2
So, we will be adding (3)^2 on both sides
So, The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is:
The mean ( average ) is given as 1200 hours.
The standard deviation is 200, sample size is 100.
Find the standard error:
√(200^2 / 100) = 20
Now calculate the confidence interval. For 95% the Z number is 1.96
Multiply Z by the standard error:
1.96 x 20 =39.2
Now find the range that the mean should be within:
1200 - 39.2 = 1160.8
1200 + 39.2 = 1239.2
The samples should be between 1160.8 and 1239.2 for a 95% confidence interval.
Since the average was 1050, which is below 1160.8 the bulbs are not in compliance.
Answer:
4%
Step-by-step explanation:
264 interest/3 years=88 interest/year
principal x interest rate =interest/year
2200 x interest rate =88
interest rate =88/2200
interest rate =.04 or 4%
