Which formula shows a joint variation?
djyliett [7]

The answer is the first option: I, II and III.

The explanation is shown below:

1. By definition, there is a joint variation  when a variable depends on two or more different variables. Therefore, you can express it as following:

y=kxz

Where x,y and z are the variables and k is the constant of proportionality.

As you can see, y is directly proportional to x and z.

2. Keeping the information above, you have:

I) V=lwh (V varies jointly with l, w and h.

II) V=\frac{1}{3}r^{2}h\pi (If \frac{\pi}{3} is the constant of proportionality, V varies jointly with r^{2} and h).

III) V=Bh (V varies jointly with B and h.

One letter is selected from the word "statistics." What is the probability that an "s" or "t" is chosen?
Pavel [41]

Answer:

3/5

Step-by-step explanation:

There are 10 letters in the word "statistics".

Out of which, there are 3 s's and 3 t's.  

So, the question asks what's the probability to get a S or a T out of 10 letters.

Since the number of S's (3) and the number of T's equal 6, that means you have 6 chances out of 10 to pick an S or a T.

6/10 or if we simplify/reduce it... we get 3/5.
