Find the number of 4-digit numbers that contain at least three even digits.
mylen [45]

Answer:

2625

Step-by-step explanation:

First let's see all the possible combinations.

(Even=E, Odd= O)

1) EEEO

2) EEOE

3) EOEE

4) OEEE

5) EEEE

Now let's see what E and O possibly could be

E = 0, 2, 4, 5, 6 and 8 (5)

O = 1, 3, 5, 7, 9 (5)

Now we are just simply gonna multiply

1) EEEO = 4*5*5*5

2) EEOE = 4*5*5*5

3) EOEE = 4*5*5*5

4) OEEE = 5*5*5*5

5) EEEE = 4*5*5*5

The even contains a 0, so you can't put 0 in, so (5-1=4), there are only 4 digits for the even.

500 times 4 = 2000

5⁴ = 625

2000+625= 2625

The first four terms of a pattern are given below. 4, -1, -6, -11, ... What is the eighth term of the pattern?
zavuch27 [327]

Answer:

  -31

Step-by-step explanation:

If we continue to subtract 5 from the previous term, the sequence continues ...

  4, -1, -6, -11, -16, -21, -26, -31, -36, ...

The 8th term is -31.

_____

This is an arithmetic sequence with first term a1 = 4 and common difference d = -5. The general term (an) of such a sequence is ...

  an = a1 +d(n -1)

Filling in the values for this sequence, the general term is ...

  an = 4 -5(n -1)

Then the 8th term is ...

  a8 = 4 -5(8 -1) = 4 -35

  a8 = -31
