Answer:
C. The graph of the function starts high and ends low
Step-by-step explanation:
For
, as
approaches negative infinity,
approaches infinity, and as
approaches infinity,
approaches negative infinity.
Thus, we have:

This corresponds with answer choice C. The graph of the function starts high and ends low.
Answer:
Step-by-step explanation:
B+8.3=0
B=0-8.3
B=-8.3
Answer:
x = 108 because of supplementary angles
Step-by-step explanation:
Solving for x:
Since x and 72 are supplemenatry angles, they'll equal to 180, so:
x + 72 = 180
x = 180 - 72
x = 108
Answer:
Probability D
Step-by-step explanation:
The probability distribution should be 1
Probability A
Add the probabilities
.2+.2+.2+.2+.2+.2 = 1.2 >1 cannot happen
Probability B
Add the probabilities
.1+.2+.3+.3+.2+.1 = 1.2 >1 cannot happen
Probability C
Add the probabilities
.1+.2+.3+0+.1+.1 = .8 <1 the probability should be 1
Probability D
Add the probabilities
.2+.1+.1+.5+0+.1 = 1 This is a correct probability distribution
Answer:

Step-by-step explanation:
-This is a binomial probability distribution problem.
-Given that p=0.86 and n=11, the sample variance can be calculated using the formula:

#We substitute the given parameters in the formula to solve for variance:

Hence, the sample variance is 1.32
