F(1) = (1)^2 + 1 = 2
g(4) = 3*4+1 = 13
2f(1) + 3g(4) = 2*2 + 3*13 = 43
Part A: Maria rented a coat at $285 for 3 days. If she rents the same coat for 6 days, she has to pay a total rent of $510.
Write an equation in the standard form to represent the total rent (y) that Maria has to pay for renting the coat for x days. (4 points)
Part B: Write the equation obtained in Part A using function notation. (2 points)
Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)
(10 points) it is 38
Answer: I believe that, at that specific rate, it will take Suzanne 100 hours to drive 4,000 miles.
Answer:
C.I. at 95% is as C.I.[0.7504 to 0.8162]
Step-by-step explanation:
Given:
Total number n=600
and Required No of students=x=470
To Find:
Determine a 95% confidence interval .
Solution:
Using normal distribution table for Z,
when 95 % C.I. Z=1.96
Now calculate ,
Population proportion,p=x/n
p=470/600
p=0.7833
Now calculate margin of error
MOE=Z*Sqrt[p(1-p)/n]
MOE=1.96*Sqrt[(0.7833*0.21667)/600]
=1.96*Sqrt(0.00028286)
=1.96*0.01681
=0.0329
So
The Boundaries will be as follows:
1)p-MOE
=0.7833-0.0329
=0.7504
2)p+MOE
=0.7833+0.0329
=0.8162
Answer:
56 yds
Step-by-step explanation:
Simply add up all the sides to find your perimeter:
12 + 12 + 18 + 14 = 56
