Find the three arithmetic means in this sequence 14 and 26

1 answer:

7 0

We subtract them and divide by four to find the common difference d. The intermediate means implies that there are four increments, thus we shall have:
(26-14)=12
hence
12/4=3
thus
d=2 and the missing means are:
26, 23,20,17,14

Hello!

There are only six was to to role a number less than four. 1 and 1. 1 and 2. 2 and 1. 1 and 3. 2 and 2. 3 and 3 and 1.

The first number on the die could be 1, and the second die could have a probability of rolling the second number on it. Giving us a probability of 1/6.

We can subtract the calculated probability from rolling less than four from 1 to find the probability of rolling more than 5:

1 - 1/6 = 5/6

So, your answer should be D 5/6.
