y = 0.75x + 53.67
Step-by-step explanation:
Answer:
y=53.67+0.75x
Step-by-step explanation:
53.67 is the initial price upon paying to rent the car. 0.75 is for additional mile, so it is multiplying x in order for it to count for the mileage. Finally it is equivalent to Y because Y will be the final cost.

Answer:

Answer:
x = 2
y = 1
z = 4
Step-by-step explanation:
Step 1:
2x + y + z = 9
3x - y = z = 9
5x + 2z = 18 <-- add x and y
Step 2:
-x -y + z = 1
2x + y + z = 9
x + 2z = 10
Step 3:
-(x + 2z = 10) = -x - 2z = -10
5x + 2z = 18
-x - 2z = -10
4x = 8
x = 2
Step 4: solve for z
-x - 2z = -10 <-- Plug x
-(2) - 2z = -10
-2z = -8
z = 4
Step 5: solve for y
2x + y + z = 9
2(2) + y + 4 = 9
8 + y = 9
y = 1

Answers
Answer:
A) A ∩ C means in both sets, in this case A and C, and in this question all students both over 20 years and with social stratum of 1, 2 and 3.
B) A ∪ B means in either set or both, both will do, in this case meaning all students in A or B or any in between, and in this question all students over 20 years and/or are women.
C) As is already explained above, B ∪ C means in this question all students that are women and/or have social stratum of 1, 2, and 3.
D) This is the same as A). Refer to A).
E) A ∪ C is already explained above, and in this question means all students over 20 years and/or have social stratum of 1, 2, and 3.
F) Same as E). Refer to E).
G) Same as A). Refer to A).
H) A ∩ B ∩ C means in students in all three sets simultaneously, and in this question all students that are over 20 years, women, and with social stratum of 1, 2 and 3.
I) A - B, in set theory would mean all students in A but not in B, in other words the difference. In this question, it would mean all students over 20 years that are not women.
J) (A - B) ∩ C would mean, as already explained above, all students over 20 years that are not women and with social stratum of 1, 2 and 3. Usually, it's easier to treat all unions or intersections or whatnot inside brackets as one whole thing, kind of like how you do algebra.
K) B 4 C is nonsensical, there is nothing in set theory like this.
L) Same as K).
The given description between C) and D) would be that they are the same, and comparing F) and G), it seems that the question is trying to make the point that they are almost the same but defined differently.

The owner of an orange grove estimates that if 24 trees are planted per acre, then each mature tree will yield 600 oranges per year. For each additional tree planted per acre, the number of oranges produced by each tree decreases by 12 per year. How many trees should be planted per acre to obtain the most oranges per year
Answers
Answer:
16428 oranges
Explanation:
Total yield = number of trees × number of oranges in each tree
Initial yield = 600×24= 14400 oranges
To find the equation needed, let x = additional trees and y= total yield
Number of trees = 24 +x
Number of oranges in each tree = 600-12x
Equation of total yield y= (24+x)(600-12x)
y= 14400-288x+600x-12x²
y= -12x²+312x+14400
Using a graphing calculator, from the graph drawn for this quadratic equation, we notice that it is a parabola. Therefore to find the maximum value, we should find the maximum point which is at the vertex of the parabola, we use the formula x= -b/2a
A quadratic equation is such: ax²+bx+c
Therefore x =-312/2×-12
x= -312/-24
x= 13
So we can conclude that in order to maximise oranges from the trees, the person needs to plant an additional 13 trees. Substituting from the above:
24+x=24+13= 37 trees in total
y= -12x²+312x+14400= -12×13²+312×13+14400= -2028+4056+14400
=16428 oranges in total yield
The number of trees that gives the most yield is 37
The given parameters are:
Trees per acre = 24Yield = 600Represent the additional number of trees with x.
So, we have:
Trees per acre = 24 + xYield = 600 - 12xThe equation that represents the total yield (y) becomes
[tex]y = (24 + x) \times (600 - 12x)[/tex]
Expand
[tex]y= 14400-288x+600x-12x\²[/tex]
Evaluate the like terms
[tex]y= 14400+312x-12x\²[/tex]
Rewrite as:
[tex]y= -12x\²+312x+14400[/tex]
Differentiate
[tex]y'= -24x+312[/tex]
Set to 0
[tex]-24x+312 = 0[/tex]
Solve for x
[tex]-24x=-312[/tex]
[tex]x=13[/tex]
Recall that:
Trees per acre = 24 + x
This gives
[tex]Trees = 24 + 13[/tex]
[tex]Trees = 37[/tex]
Hence, the number of trees that gives the most yield is 37

The length of the remaining piece of thread is 1/16
Step-by-step explanation:
Given:
A tailor cuts a piece of thread One-half of an inch long from a piece Nine-sixteenths of an inch long.
Now, to find the length of the remaining piece of thread.
Total thread = 9/16
Tailor cuts a piece of thread = 1/2
Now, to get the length of the remaining piece of thread by subtracting tailor cuts a piece of thread from the total thread:
9/16-1/2= 9-8/16 = 1/16
Therefore, the length of the remaining piece of thread is 1/16 :)

A random sample of 12 recent college graduates reported an average starting salary of $54,000 with a standard deviation of $6,000.
a. Construct a 95% confidence interval for the mean starting salary of college graduates.
a. 50188 to 57812$
b. 45,0000 to 50,000$
c. 48,000 to 60,000$
d. 50,000 to 54000$
b. The National Association of Colleges and Employers reports that the mean starting salary for 2017 college graduates is $50,516. Does your confidence interval (part a) indicate that starting salaries have significantly changed since 2017? Why or why not?
Answers
Answer: a.) $50188 to $57812
Step-by-step explanation: Confidence Interval (CI) is an interval of values in which we are confident the true mean is in.
The interval is calculated as
x ± [tex]z\frac{s}{\sqrt{n} }[/tex]
a. For a 95% CI, z-value is 1.96.
Solving:
54,000 ± [tex]1.96.\frac{6000}{\sqrt{12} }[/tex]
54,000 ± [tex]1.96\frac{6000}{3.464}[/tex]
54,000 ± 1.96*1732.102
54,000 ± 3395
This means the interval is
50605 < μ < 57395
With a 95% confidence interval, the mean starting salary of college graduates is between 50605 and 57395 or from 50188 to 57812$.
b. The mean starting salary for college students in 2017 is $50,516, which is in the confidence interval. Therefore, since we 95% sure the real mean is between 50188 and 57812, there was no significant change since 2017.

The owner of a large fast food chain is considering whether to re-open the dining rooms of his restaurants now that it is legal in the state of Georgia. He is interested to know what percentage of his employees support the re-opening, so he decides to conduct a survey. (a) Which of the following plans would be more likely to produce a sample statistic very close to the true percentage who support re-opening? A simple random sample of 34 employees A simple random sample of 340 employees Both plans are equally likely to get this result, since they are both random samples. (b) He thinks it would be easier to sample employees by randomly selecting franchise locations (individual restaurants) and asking managers to administer surveys to all the workers at the selected restaurants, what kind of sampling method should he use? a) Cluster sample b) Systematic sample c) Convenience sample d) Stratified sample
Answers
Answer:
a) A simple random sample of 340 employees
b) a) Cluster sample
Step-by-step explanation:
a) Remember, the sample size of most research work is a factor to consider in other to determine if the data collected represents the true percentage of the entire population.
Hence, a small random sample of 34 employees will not give more precise information than a larger sample of 340 employees because the larger sample contains more representation of the population.
b) A cluster sample is best used in this case because it involves dividing the population into several clusters or groups, then the researcher randomly selects a particular cluster or group in other collect research data for analysis.
Whereas in this case, the randomly selected clusters are the different (individual restaurant) franchise locations.
