Answer:

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: 2x + 4

Step-by-step explanation:

the first thing i did was look at the y-intercept, and compare that to the y-intercepts in the answers. luckily, all of the y-intercepts in the answers are different. the line passes through the y-axis, at positive 4, so we automatically know that's the answer

Answer:9

Step-by-step explanation:

I think it’s 9 as the area of a parallelogram is A=bh. The height is 3 as well as the base so times them together equates to 9.

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.

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:

Represent the additional number of trees with x.

So, we have:

The 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

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.

Answer:

m∠SRT = 33°     ∵ m∠QRT = m∠SRT

Step-by-step explanation:

Given the diagram,

RT bisects ∠SRQ, and m∠QRT = 33°

RT bisecting ∠SRQ means RT will bisect ∠SRQ into two equal angles, which are:

m∠QRT = m∠SRT

as

m∠QRT = 33°

so

m∠SRT = 33°     ∵ m∠QRT = m∠SRT

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

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.
