Answer:
[2, 6].
Step-by-step explanation:
Notice that there is a red line (graph) only for [2, 6]. Thus, the domain of this function is [2, 6].
The y-intercept, in this case, represents when x is at 0, or when she just began observing.
Answer:
Total = $31.71
Step-by-step explanation:
Given data:
pounds of turkey = 2.15 at a rate of 7.89/ pound
pounds of lamb = 1.87 at a rate of 7.89/ pound
cost of each item as
cost(T) = 2.15 × 7.89
cost(T) = $16.96
And for lamb
cost(L) = 1.87 × 7.89
cost (L) = $14.75
Total cost will be the summation of both cost
Total = 16.96 + 14.75
Total = $31.71
Answer:
5% of $22 is $1.10.
22+1.10=23.10
23.10 is less than 24
Step-by-step explanation:
Answer:
0.071 to 0.129
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:
In a sample of 400 voters, 360 indicated they favor the incumbent governor. This means that 400-360 = 40 do not favor the incumbent governor. So 
95% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The correct answer is:
0.071 to 0.129
