Answer:
M
Step-by-step explanation:
We have been given side AB and BC
AB must be 6 as it is between 4 and -2 and that distance is 6 (we have been given no units).
BC must be also 6 as it starts at -4 and ends at 2.
Pythagoras Theorem = a^2 + b^2 = c^2 (^2 means squared)
C is the hypotenuse (longest side) and this is what we are trying to find...
6^2 + 6^2 = 36+36=72
So AC is 72, however we need to square root this to get our final answer.
72 doesn't square easily, so we will use surds. 72 is 36*2 and 36 is a square number hence why...
AC is 6 root 2

Answer:
C.
Step-by-step explanation:
For a relation to be considered a function, all x-coordinates must be different.
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.
