To answer this question we will set and solve a system of equations.
Let A be the speed (in miles per hour) of the airplane in still air, and W be the wind speed (in miles per hour).
Since the airplane flying with the wind takes 4 hours to travel a distance of 1200 miles and flying against the wind takes 5 hours to travel the same distance, then we can set the following equation:
\(\begin{gathered} 4A+4W=1200, \\ 5A-5W=1200. \end{gathered}\)Dividing the first equation by 4 we get:
\(\begin{gathered} \frac{4A+4W}{4}=\frac{1200}{4}, \\ A+W=300. \end{gathered}\)Subtracting A from the above equation we get:
\(\begin{gathered} A+W-A=300-A, \\ W=300-A\text{.} \end{gathered}\)Substituting the above equation in the second one we get:
\(5A-5(300-A)=1200.\)Simplifying the above result we get:
\(\begin{gathered} 5A-1500+5A=1200, \\ 10A-1500=1200. \end{gathered}\)Adding 1500 to the above equation we get:
\(\begin{gathered} 10A-1500+1500=1200+1500, \\ 10A=2700. \end{gathered}\)Dividing the above equation by 10 we get:
\(\begin{gathered} \frac{10A}{10}=\frac{2700}{10}, \\ A=270. \end{gathered}\)Finally, substituting A=270 at W=300-A we get:
\(\begin{gathered} W=300-270, \\ W=30. \end{gathered}\)Answer:
The speed of the airplane in still air is 270 miles per hour.
The wind speed is 30 miles per hour.
The mean increase in the United States population is about four people per minute.
Find the probability that the increase in the U.S. population is any given minute is
a. Exactly 6 people.
b. More than three people.
c. At most four people.
Answers
a) The probability of exactly 6 people increasing in the U.S. population in a given minute is approximately 0.1042 or 10.42%.
b) The probability of more than three people increasing in the U.S. population in a given minute is approximately 0.3712 or 37.12%.
c) The probability of at most four people increasing in the U.S. population in a given minute is approximately 0.6288 or 62.88%.
a. To find the probability of exactly 6 people increasing in the U.S. population in a given minute, we can use the Poisson distribution with a mean of 4 people per minute:
\(P(X=6) = (e^(-4) * 4^6) / 6! = 0.1042\)
Therefore, the probability of exactly 6 people increasing in the U.S. population in a given minute is approximately 0.1042 or 10.42%.
b. To find the probability of more than three people increasing in the U.S. population in a given minute, we can use the cumulative distribution function of the Poisson distribution:
\(P(X > 3) = 1 - P(X ≤ 3) = 1 - ∑(k=0 to 3) [(e^(-4) * 4^k) / k!] = 1 - 0.6288 = 0.3712\)
Therefore, the probability of more than three people increasing in the U.S. population in a given minute is approximately 0.3712 or 37.12%.
c. To find the probability of at most four people increasing in the U.S. population in a given minute, we can again use the cumulative distribution function of the Poisson distribution:
\(P(X ≤ 4) = ∑(k=0 to 4) [(e^(-4) * 4^k) / k!] = 0.6288\)
Therefore, the probability of at most four people increasing in the U.S. population in a given minute is approximately 0.6288 or 62.88%.

.In order to increase the value of the F statistic, which of the following must occur?
a. MSwithin > MSbetween
b. MSwithin = MSbetween
c. MSwithin < MSbetween
d. Ratio = 1
Answers
If MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.
How the F statistic is calculated?The F statistic is calculated by dividing the variance between groups (MSbetween) by the variance within groups (MSwithin). Therefore, to increase the value of the F statistic, either the numerator (MSbetween) needs to increase, or the denominator (MSwithin) needs to decrease.
So, the answer is:
a. MSwithin > MSbetween
If the variance within groups (MSwithin) is reduced or the variance between groups (MSbetween) is increased, the F statistic will increase. Therefore, if MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

At the movie theatre, child admission is and adult admission is . On Wednesday, tickets were sold for a total sales of . How many child tickets were sold that day
Answers
The child tickets were sold that day is 82.
Given the cost of child admission $6.30 and the cost of adult admission $9.80 and on Wednesday 144 tickets were sold for a total sales of $1124.20.
Let the child tickets are x and adult tickets are y.
On Monday, 144 tickets were sold for a total sales.
x+y=144 ........(1)
Total sales = $1124.20
Need to find the child tickets sold on Wednesday.
Total sales = 6.30x+9.80y
Total sales = $1124.20
So,6.30x+9.80y=1124.20 .......(2)
Find the value of y from equation (1), we get
x+y-x=144-x
y=144-x
Now, we will substitute the value of y in equation (2) to find the value of x, we get
6.30x+9.80(144-x)=1124.20
Apply the distributive property that is a(b+c)=ab+ac, we get
6.30x+9.80×144-9.80x=1124.20
6.30x+1411.2-9.80x=1124.20
Combine the variable terms on left side, we get
1411.2-3.5x=1124.20
subtract 1411.2 from both sides, we get
1411.2-3.5x-1411.2=1124.20-1411.2
-3.5x=-287
Divide both sides with -3.5x, we get
-3.5x/(-3.5)=-287/(-3.5)
x=82
Therefore, 82 child tickets were sold on Wednesday when cost of child admission $6.30 and the cost of adult admission $9.80.

find the critical value(s) and rejection region(s) for the type of z-test with level of significance . include a graph with your answer. right-tailed test, a=0.03.
Answers
Answer:
c
Step-by-step explanation:
The red line represents the critical value, and the shaded region on the right-hand side of the red line represents the rejection region. If the calculated test statistic is greater than the critical value of z, which is 1.88 in this case, we will reject the null hypothesis.
The critical value(s) and rejection region(s) for the type of z-test with a level of significance a = 0.03 and a right-tailed test are as follows :Step 1: Determine the critical value of zThe critical value is calculated by using the normal distribution table and the level of significance. A right-tailed test will have a critical value of zα. For a level of significance of 0.03, we will look for the z-value that corresponds to 0.03 in the normal distribution table.Critical value for a = 0.03 is z = 1.88 (approx).Step 2: Determine the Rejection Region The rejection region for a right-tailed test is defined as any z-value that is greater than the critical value. That is, if the test statistic is greater than 1.88, we reject the null hypothesis at the 0.03 level of significance, and if it is less than or equal to 1.88, we fail to reject the null hypothesis.Therefore, the rejection region for a right-tailed test with a level of significance of 0.03 is as follows:Rejection Region: Z > 1.88 OR Z ≤ -1.88Graph: The graph for the given values will be as follows:The red line represents the critical value, and the shaded region on the right-hand side of the red line represents the rejection region. If the calculated test statistic is greater than the critical value of z, which is 1.88 in this case, we will reject the null hypothesis.

Aaron is staying at a hotel that charges $99.95 per night plus tax for a room. A tax of 7% is applied to the room rate, and an additional onetime untaxed fee of $9.00 is charged by the hotel. What is Aaron’s total charge, in dollars, for staying 5 nights?
Answers
Answer: $543.7325
Step-by-step explanation:
room rate = $99.95 / night
Tax fee = 7% of room rate
Therefore, tax fee = 7% of $99.95
Tax fee = 0.07 × $99.95
Room charge =[$99.95 + 0.07($99.95)]
Room charge = 1.07($99.95) per night
Additional onetime untaxed fee = $9
Therefore for 5 nights :
Room charge = 5×[1.07($99.95)] +
Total room charge = 5×[1.07($99.95)] + one time untaxed fee
Total room charge = 5×[1.07($99.95)] + $9
= $543.7325

The graph of f(x)= |x| is transformed to g(x) = x + 11-7. On which interval is the function decreasing?
O (-∞, -7)
O (-00,-1)
O (-00, 1)
O (-∞0,7)
Answers
Answer:
The interval of the decreasing function is (-∞ , -1) ⇒ g(x)
The interval of the decreasing function is (-∞ , 0) ⇒ f(x)
Step-by-step explanation:
* Lets explain how to solve it
- Decreasing function means a function with a graph that moves
downward as it is followed from left to right.
- For example, any line with a negative slope is decreasing function
- Lets look to the attached graph to understand the meaning of the
decreasing function
∵ f(x) = IxI ⇒ green graph
∵ g(x) = Ix + 1I - 7 ⇒ purple graph
- From the graph f(x) translated 1 unit to the left and 7 units down to
form g(x)
- The domains of f(x) and g(x) are all real numbers {x : x ∈ R}
- The range of f(x) is {y : y ≥ 0}
- The range of g(x) is {y : y ≥ -7}
# For f(x)
- The slope of the green line from (-∞ , 0) is negative
- The slope of the green line from (0 , ∞) is positive
# For g(x)
- The slope of the purple line from (-∞ , -1) is negative
- The slope of the purple line from (-1 , ∞) is positive
∵ The line with negative slope represent decreasing function
∴ The interval of the decreasing function is (-∞ , -1) ⇒ g(x)
∴ The interval of the decreasing function is (-∞ , 0) ⇒ f(x)
