1 answer:
ikadub [295]3 years ago

Answer:

a) yes

b) 2560

Step-by-step explanation:

An exponential function has a common ratio between points uniformly spaced. Here, the data points are 10 years apart.

The ratio of the first two values is 4000/5000 = 0.8.

The ratio of the next two values is 3200/4000 = 0.8.

These ratios are the same, so the data is consistent with an exponential function.

The common ratio can be used to predict the next value. The next value is predicted to be ...

  3200 × 0.8 = 2560

A basketball player participates in a one-and-one free throw situation. The player has a 70% free throw percentage. What is the
julia-pushkina [17]

Answer:

The average number of points this player will get in 100 one-and-one free throw situations is 70.

Step-by-step explanation:

For each free throw, there are only two possible outcomes. Either the player makes it, or he does not. The probability of the player making a free throw is independent of other free throws. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

70% free throw percentage.

This means that p = 0.7

What is the average number of points this player will get in 100 one-and-one free throw situations?

This is E(X) when n = 100. So

E(X) = np = 100*0.7 = 70

The average number of points this player will get in 100 one-and-one free throw situations is 70.

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. The
frosja888 [35]

Answer:

Step-by-step explanation:

Joint variation has the equation

y = kxz

k is the constant of variation and needs to be solved for using the initial conditions, then filled in later to another equation related to the given info to solve for something else.  We are given y = amount of oil used, x = distance traveled, z-squared is the speed.  Our equation looks like this, to be exact:

y=kxz^2

Filling in with the initial conditions:

34=k(60)(20)^2 which gives us the

k = .0014166667

Now we need to find the amount of oil used, y, under other circumstances, but this time we have our k.

y=(.0014166667)(32)(23)^2

which gives us that the amount of oil used, when rounded to the tenths,

y = 24.0 barrels
