An arts academy requires there to be 6 teachers for every 144 students and 5 tutors for every 40 students. How many students does the academy have per teacher? Per tutor? How many tutors does the academy need if it has 72 students

Answers

Answer:

3 teachers and 9 tutors

Step-by-step explanation:

Answer:

There are 24 students per teacher and 8 students per tutor. If the academy has 72 students, then 9 tutors would be needed.

Step-by-step explanation:

We will start with the question, how many students does the academy have per teacher. To find this, we need to set up the equation. 144 will be the number of students, 6 will be the number of teachers, and x will be the number of students per teacher.

144/6=x

24=x

So, there are 24 students for every teacher.

We could also do this as a ratio. We would do the same thing. We would divide by six to get our answer.

144:6

Make the six one.

24:1

This shows that there are 24 students for every teacher.

Now to find out how many per tutor.

We will do the same thing as before, minus the ratio, though you could still use the ratio. Remember, 40 is the number of students, 5 is the number of tutors, and x is the number of students per tutor.

40\5=x

8=x

So there are 8 students per tutor.

Now we will use this knowledge to solve for how many tutors are needed if the academy has 72 students.

We will set up our equation. 72 will be the students, we will use eight since that is how many students are needed per tutor, and x will be the number of tutors needed.

72/8=x

9=x

So this means that if the academy has 72 students, then it will need 9 tutors.

The director of student life at a university wants to estimate the proportion of undergraduate students who regularly park a car on campus. Describe how to select a stratified random sample of approximately 100 students. Explain your choice of strata and why stratified random sampling might be preferred in this context.

Answers

Random sampling involves selecting a sample where each element of the sample have an equal probability of selection.

From the question, we understand that the director wants to make use of a stratified random sampling technique.

The stratified random sampling technique involves selecting the sample (i.e. 100 students), by dividing the whole undergraduate students into groups (i.e. strata), and then select a proportion from each group.

A possible way to achieve this, is as follows:

Divide the undergraduate students in faculties (assume the university has 10 faculties)Then select 10 students from each of the 10 faculties.

With the above highlights, the director would be able to make the selection.

Mr. Cash bought d dollars worth of stock. During the first year, the value of the stock tripled. The next year, the value of the stock decreased by $1200. (a) Write an expression in terms of d to represent the value of the stock after two years. (b) If an initial investment is $1,000, determine its value at the end of 2 years.

Answers

Answer:

1. 3D-1200 = value after two years.

2. $1800 = value after two years

Step-by-step explanation:

When the value of D triples, 3 times D = 3D. value of the stock after two years decreased, would be the -1200.

When you get the value of 1,000 you can plug it in to get 3 (1000) - 1200 = Stock price after two years

A plane flies at a speed 580 km/hr at a constant height of 16 km. How rapidly is the angle of elevation to the plane changing when the plane is directly above a point 125 km away from the observer?

Answers

Answer:

-0.584 rad/hr, rounded to the nearest 1000th  

Step-by-step explanation:

Let D = D(t) = the horizontal distance from the observer to the plane at time t in units of km.  

Let E = E(t) = the angle of elevation at time t in units of Radians.

Then, by geometry,

tan(E) = 16 / D, and furthermore, we have that

tan(E) = 16 * D^(-1)

d/dt (tan(E)) = d/dt ( 16 * D^(-1))

sec^2 (E) * dE/dt = 16(-1)(D^(-2)) * dD/dt

( sqrt(D^2 + 16^2) / D )^2 * dE/dt = -16 (D^(-2)) * dD/dt

(D^2 + 16^2)/D^2  *  dE/dt = -16 (D^(-2)) * dD/dt

dE/dt = -16 (D^(-2)) * dD/dt * D^2 / (D^2 + 16^2)

dE/dt = -16 (dD/dt) / (D^2 + 16^2)

dE/dt = -16 (580 km/hr) / (125^2 + 16^2), at time t such that D(t) = 125 km,

dE/dt = (-9280 / 15881) rad/hr

dE/dt = -0.584 rad/hr, rounded to the nearest 1000th

By Trigonometric identity,

Sin²(©) + Cos²(©) = 1

Sin²(©) = 1- Cos²(©)

Cos²(©) = (3/5)² = 9/25

Sin²(©) = 1- 9/25 = 16/25

Taking the root of both sides,

√(Sin²(©)) = √(16/25)

A thread was folded in half, and then it was folded again, forming a bundle. Then the thread was cut into pieces by a striaght cut through the enitre bundle. Ine of the pieces is 8 cm, and the longest piece is 18 cm. What is the longest possible length of the thread

Answers

The longest possible length of the thread is;

Length = 144 cm

Let the length of the thread be x cm.

Now, it is first folded in half. This means divided into 2. Thus, we now have length as x/2.

We are told it is folded again. This means the length after second folding is now; (x/2) ÷ 2 = x/4.

We are told that there is now a straight cut through the entire bundle with one of the pieces being 8cm and the longer piece being 18 cm.

This means the ratio is; 8:18

Since the new length after the final folding is x/4, then it means after cutting;

longer length will be; [tex](\frac{18}{8 + 18})[/tex] [tex]* (\frac{x}{4})[/tex]

Thus, we now have;

18 = (18/26) × (x/4)

18 will cancel out to give; x = 26 × 4

x = 144 cm

Therefore the longest possible length of the thread = 144 cm
