An SRS of 100 flights by Speedy Airlines showed that 64 were on time. An SRS of 100 flights by Happy Airlines showed that 80 were on time. Let pS be the proportion of on-time flights for all Speedy Airline flights, and let pH be the proportion of all on-time flights for all Happy Airlines flights. Is there evidence of a difference in the on-time rate for the two airlines
Answers
Answer:
Yes, Since pH = 0.8 > pS = 0.64
So, on average, more Happy Airlines flights were on time than Speedy Airlines Flights
Step-by-step explanation:
Since for Speedy Airlines, 64 out of a hundred were on time, the proportion is,
\(pS = 64/100 = 16/25=0.64\\pS=0.64\)
And for Happy Airlines, 80 out of 100 were on time, so,
\(pH = 80/100=4/5\\pH=0.8\)
since pH is greater than pS, so we conclude that there is evidence of a difference in the on-time rate for the two airlines
That is, Happy Airlines flights were on time 80% of the time and Speedy Airlines flights were on time 64% of the time
does anyone know the area and perimeter of the figure?
Answers
Answer:
Area: 776.7 ft²
Perimeter: 55.1 ft
Step-by-step explanation:
The figure is composed of two semi-circles and a rectangle, solve for the area of each figure:
Two semi-circles (which is one circle because they have the same diameter):
\(A_1=\pi r^2\\A_1=\pi 7.5^2\\A_1=176.714586764...\)
The rectangle:
\(A_2=bh\\A_2=4*15\\A_2=60\)
Add them up to get:
\(A=176.714586764...+600\\A=776.714586764...\)
Rounding gives 776.7
Now, the perimeter.
Solve for the circumference of the circle and add only the bases of the rectangle:
\(C=d\pi \\C=15\pi\\C=47.1238898038...\)
And add the two bases:
\(P=47.1238898038...+2b\\P=47.1238898038...+2(4)\\P=47.1238898038...+8\\P=55.1238898038...\)
Rounding gives 55.1

circle graph titled New York City visitor's transportation, with five sections labeled subway 80 percent, bicycle 20 percent, car service 30 percent, bus 16 percent, and walk 54 percent
Answers
So, the circle graph entitled New York City visitor's transportation with five sections labelled walk 40%, bicycle 8%, car service 15%, bus 10%, and subway 27% is the proper option that displays the data in the circular graphs.
Explain about the circle graphs:A circle represents 360 degrees. A circle can be split up into smaller sections. An arc is a segment of a circle, and arcs are named based on their angles.
To illustrate information and data, use a circle graph or pie chart. Often, a circle graph is used to quickly and proportionately display the findings of an investigation.
Given data:
Type of Transportation Number of Visitors Percentage
Walk 120 120*100/ 300 = 40%
Bicycle 24 24*100/ 300 = 8%
Car Service 45 45*100/ 300 = 15%
Bus 30 30*100/ 300 = 10%
Subway 81 81*100/ 300 = 27%
Total 300
So, the circle graph entitled New York City visitor's transportation with five sections labelled walk 40%, bicycle 8%, car service 15%, bus 10%, and subway 27% is the proper option that displays the data in the circular graphs.

iii. EDD

v. From the list (i to iv above) recommend the best rule to sequence the jobs
Answers
The recommended rule to sequence the jobs for minimum flow time is the EDD (Earliest Due Date) rule.
The EDD rule prioritizes jobs based on their due dates, where jobs with earlier due dates are given higher priority. By sequencing the jobs in order of their due dates, the goal is to minimize the total flow time, which is the sum of the time it takes to complete each job.
In this case, applying the EDD rule, the sequence of jobs would be as follows:
D (Due on Friday 10th June)
F (Due on Tuesday 14th June)
E (Due on Wednesday 15th June)
C (Due on Friday 17th June)
G (Due on Thursday 16th June)
H (Due on Saturday 18th June)
A (Due on Monday 13th June)
B (Due on Monday 20th June)
By following the EDD rule, we aim to complete the jobs with earlier due dates first, minimizing the flow time and ensuring timely delivery of the orders.
Therefore, the recommended rule for sequencing the jobs in this scenario is the EDD (Earliest Due Date) rule.

what is the value of x in the equation 3^(2x-1)=27?
Answers
Answer:
x=2
Explanation:
Given the equation:
\(3^{2x-1}=27\)To solve for x, begin by writing 27 as a power of 3.
\(3^{2x-1}=3^3\)Next, since both sides of the equation have the same base, 3, it follows from the law of indices that:
\(\begin{gathered} a^x=a^y\implies x=y \\ \text{Therefore:} \\ 3^{2x-1}=3^3\implies2x-1=3 \end{gathered}\)We then solve the resulting equation for x.
\(\begin{gathered} 2x-1=3 \\ \text{Add 1 to both sides} \\ 2x-1+1=3+1 \\ 2x=4 \\ \text{Divide both sides by 2} \\ \frac{2x}{2}=\frac{4}{2} \\ x=2 \end{gathered}\)The value of x in the equation is 2.
If f(x)=7x+3 ,what is f^-1(x)?
Answers
Answer:
\(\displaystyle{f^{-1}(x)=\dfrac{x}{7}-\dfrac{3}{7}}\)
Step-by-step explanation:
Swap f(x) and x position of the function, thus:
\(\displaystyle{x=7f(x)+3}\)
Then solve for f(x), subtract 3 both sides and then divide both by 7:
\(\displaystyle{x-3=7f(x)}\\\\\displaystyle{\dfrac{x}{7}-\dfrac{3}{7}=f(x)}\)
Since the function has been inverted, therefore:
\(\displaystyle{f^{-1}(x)=\dfrac{x}{7}-\dfrac{3}{7}}\)
And we can prove the answer by substituting x = 1 in f(x) which results in:
\(\displaystyle{f(1)=7(1)+3 = 10}\)
The output is 10, now invert the process by substituting x = 10 in \(f^{-1}(x)\):
\(\displaystyle{f^{-1}(10)=\dfrac{10}{7}-\dfrac{3}{7}}\\\\\displaystyle{f^{-1}(10)=\dfrac{7}{7}=1}\)
The input is 1. Hence, the solution is true.

Answers
The range of the function shown in the graph is the set of all real numbers for y.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
The set of input values in the function is called domain and the set of output values are called range of the function.
So the range of the function will be the set of y values.
From the graph, it is clear that, the curve is passing corresponding to every y value.
In other words, if we draw a horizontal lines from curve, all the y values are touching the curve.
So the range is the set of all real numbers.

LoadThe weight of x refrigerators will be 250x. The weight of y pianos will be 425y. Then the restriction on the total weight is ...
250x +425y ≤ 5900 . . . . . . the load limit of the truck

Use algebraic techniques to rewrite g(x) 6x6-7x³ x² Correct as a sum or difference; then find g'(x).
Answers
The derivative of the given function in the form sum or difference is given by, g' (x) = 24 x³ - 7
Given the function is,
g (x) = [6 x⁶ - 7 x³]/x²
g (x) = (6 x⁶)/x² - (7 x³)/x²
g (x) = 6 x⁶⁻² - 7 x³⁻², since the division in exponential means subtraction of powers.
g (x) = 6 x⁴ - 7 x
Differentiating the simplified above function with respect to the variable 'x' we get,
d/dx [g (x)] = d/dx [6 x⁴ - 7 x]
g' (x) = d/dx (6 x⁴) - d/dx (7 x)
g' (x) = 6 d/dx (x⁴) - 7 d/dx (x)
g' (x) = 6 (4 x³) - 7 * 1
g' (x) = 24 x³ - 7
Hence the derivative of the function is, g' (x) = 24 x³ - 7.

The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.
In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.
CV = (Standard Deviation / Mean) * 100
CV = (5.2 / 340) * 100
CV ≈ 1.53%

Turkey, apple and waterTurkey, orange and waterTurkey, orange and juiceTurkey, apple and juiceSame for the ham:
Ham, apple and waterHam, apple and juiceHam, orange and juiceHam, orange and waterPutting these together, this gives up 8 different lunchbox combinations. If we're trying to get one and we randomly select it, then we have a 1/8 chance of grabbing the turkey sandwich and a bottle of water....
