Answer:
21 m/ph
Step-by-step explanation:
2016 divided by 96
The balloon travels 21 miles in one hour.
What is division?In mathematics, division is one kind of operation. The phrases or numbers in this process are split into the same number of parts.
Given, a hot air balloon travels 2016 miles in 96 hours.
And the balloon travels the same number of miles each hour.
To find the same numbers of miles per hour:
We use the division of 2016 by 96.
That means,
2016 / 96
= 21
Therefore, the travel time of the balloon is 21 miles per hour.

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining to be paid. The graduate makes regular payments of $8,000 each year. The graph shows the sequence. f(x)=?
Answer:
The equation is: \(f(x) = 52000 - 8000x\)
Step-by-step explanation:
Given
Initial = 52000
Rate = 8000 each year
Required
Determine the equation of the graph
The equation can be determined using.
\(Amount = Initial - Rate* Years\)
We used minus (-) because, the amount reduces as the student pays.
Let
\(y = Amount\)
\(x = Years\)
So, we have:
\(y = Initial - Rate * x\)
Substitute values for Initial and Rate
\(y = 52000 - 8000 * x\)
\(y = 52000 - 8000x\)
Express as a function:
\(f(x) = 52000 - 8000x\)
Look at the system of equations below.
y = {x + 10
y = {x – 10
Which of these statements is correct?
A. The system has no solution.

In a random sample of 8 residents of the state of Montana, the mean waste recycled per person per day was 3.0 pounds with a standard deviation of 0.23 pounds. Determine the 99% confidence interval for the mean waste recycled per person per day for the population of Montana. Assume the population is approximately normal. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
at 99%, Confidence interval is ( 2.716, 3.285 )
( 2.716 < μ < 3.285 )
Step-by-step explanation:
Given the data in the question;
sample size n = 8
mean x' = 3.0
standard deviation σ = 0.23
To calculate the confidence interval, we use the following expression;
x' ± \(t_{\alpha /2, df\)( σ/√n) ------- let this be equation
now, at 99% confidence interval;
∝ = 1 - 99% = 1 - 0.99 = 0.01
degree of freedom df = n - 1 = 8 - 1 = 7
hence t-critical value = 3.499
in equation 1, we substitute in our values;
⇒ 3.0 ± 3.499( 0.23/√8 )
⇒ 3.0 ± 0.2845
⇒ 3.0 - 0.2845, 3.0 + 0.2845
⇒ ( 2.7155, 3.2845 )
Therefore at 99%, Confidence interval is ( 2.716, 3.285 )
( 2.716 < μ < 3.285 )

Suppose that E and F are mutually exclusive events of an experiment. Show that if independent trials of this experiment are performed, then E will occur before F with probability P(E)/[P(E) + P(F)].
Define the event G as the event that neither E nor F occurs. That is, G = E^c F^c
.
P(E occurs before F) = P(E occurs before F|trial 1 is E)P(trial 1 is E)
+P(E occurs before F|trial 1 is F)P(trial 1 is F)
+P(E occurs before F|trial 1 is G)P(trial 1 is G).If E occurs on trial 1, then E occurs before F, and if F occurs on trial 1, then E does not occur before F. If G occurs on trial 1, then we start all over in determining whether E or F occurs first. Thus
P(E occurs before F) = 1 · P(E) + 0 · P(F) + P(E occurs before F)P(G).
Proved that if E and F are mutually exclusive events and independent trials of this experiment are performed, then the probability that E occurs before F is P(E)/[P(E)+P(F)].
Let's consider the probability that event E occurs before F in a single trial of the experiment. There are two possibilities: either E occurs first, or F occurs first.
The probability that E occurs first can be calculated by considering the probability of E and not F in the first trial, followed by any outcome in the subsequent trials. Since E and F are mutually exclusive, the probability of not F is 1-P(F). Therefore, the probability that E occurs first in a single trial is:
P(E and not F) = P(E) × (1-P(F))
Similarly, the probability that F occurs first in a single trial is:
P(F and not E) = P(F) × (1-P(E))
Since E and F are mutually exclusive, the event E occurring before F and the event F occurring before E are also mutually exclusive.
Geometric series with a common ratio = (1 - P(E+F)):
P(E before F) = P(E) * (1-P(F)) + P(E) * (1-P(E+F)) * (1-P(F)) + P(E) * (1-P(E+F))^2 * (1-P(F)) + ...
Using the formula for the sum of an infinite geometric series, we get:
P(E before F) = P(E) * (1-P(F)) / [1 - P(E+F)]
Substituting P(E+F) = P(E) + P(F) (since E and F are mutually exclusive) yields:
P(E before F) = P(E) / [P(E) + P(F)]

Step-by-step explanation:
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with grams of a radioactive isotope, how much will be left after 4 half-lives?
After 4 half-lives, only 1/16th (or 0.0625) of the initial amount of the radioactive isotope will remain.
The amount of a radioactive isotope remaining after a certain number of half-lives can be calculated using the formula:
Amount remaining = Initial amount × (1/2)^(number of half-lives)
In this case, we are given the initial amount as "grams" and we want to find out the amount remaining after 4 half-lives.
So, the equation becomes:
Amount remaining = Initial amount × (1/2)^4
Since each half-life reduces the quantity to half, (1/2)^4 represents the fraction of the initial amount that will remain after 4 half-lives.
Simplifying the equation:
Amount remaining = Initial amount × (1/16)
Therefore, after 4 half-lives, only 1/16th (or 0.0625) of the initial amount of the radioactive isotope will remain.

Answer:
The two equivalent expressions are 6(x − y) and 6x − 6y.
Step-by-step explanation:
For what value of A is the function, (x), continuous at x=0?
(i) \(\lim_{x \to \frac{\pi^-}{2}}\) h(x) = 3
(ii) \(\lim_{x \to \frac{\pi^+}{2}}\) h(x) = -1
(iii) h(0) = 1/7
The value of λ must be 7, for h(x) to be continuous at x = 0.
The given function is,
h(x) = 1/7, when x = 0
= 1 - 2 cos 2x, when x < π/2
= 1 + 2 cos 2x, when x > π/2
= x cos x/sin λx, when x < 0
Now,
(i) \(\lim_{x \to \frac{\pi^-}{2}}\) h(x) = \(\lim_{x \to \frac{\pi^-}{2}}\) (1 - 2 cos 2x) = 1 - 2 cos π = 1 + 2 = 3
(ii) \(\lim_{x \to \frac{\pi^+}{2}}\) h(x) = \(\lim_{x \to \frac{\pi^+}{2}}\) (1 + 2 cos 2x) = 1 + 2 cos π = 1 - 2 = -1
(iii) h(0) = 1/7
Since the function is continuous at x = 0, so
\(\lim_{x \to 0}\) h(x) = h(0)
\(\lim_{x \to 0}\) x cos x/sin λx = 1/7
\(\lim_{x \to 0}\) cos x.\(\lim_{x \to 0}\) 1/λ(sinλx/λx) = 1/7
1/λ = 1/7
λ = 7
Hence the value of λ must be 7.

Which equation has a graph parallel to the graph of 9x + 3y =22?
Answer:
y = -3x + 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = 22 in the form y = mx +c.
9x+3y = 22
3y = -9x +22
y = -3x + 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

Round your answer to the nearest tenth of a foot if necessary.
Answer:
66.9 ft
Step-by-step explanation:
Kite string forms a right triangle with the horizontal 3.5 feet off of the ground
sin 25 = opp / hyp = height / 150
sin 25 = height / 150
150 sin25 = height but it is 3.5 feet off of the ground...add that in

A 455-foot fence encloses a
pasture. What is the length of each side
of the pasture?
Answer: 50 feet, 150 feet, 75 feet, and 180 feet
Step-by-step explanation:
The side lengths are x, 3x, 1.5x and 180 (in feet) and they must all add up to 455 feet, so ....
x + 3x + 1.5x + 180 = 455
(1+3+1.5)x + 180 = 455
5.5x + 180 = 455
Subtract 180 from both sides
5.5x = 275
x = 275/5.5
x = 50 feet , but that was not really the question.
The question was the 4 side lengths.
The lengths are x, 3x, 1.5x and 180, all in feet.
x = 50 feet ----> 50 feet
3x = 3(50 feet) ---> 150 feet
1.5x = 1.5(50 feet) ---> 75 feet
180 feet (given)
We check our work by adding the four sides ---> 50+150+75+180 = 455, so that looks good.
Don't forget to label the lengths in feet!
I hope this helps.
