Answer:

2.48 × 10⁻⁵

Step-by-step explanation:

Number of people in the room of a different age = 8 people

The number of ways people can leave the room  = 8!

                                                                                 = 40320

They leave the room in ascending order is  = 1 way

The probability they leave the room in ascending order of their ages =

\frac{1}{40320} = 2.48 × 10⁻⁵

A particular geometric sequence has strictly decreasing terms. After the first term, each successive term is calculated by multi
Maksim231197 [3]

Answer:

6 possible integers

Step-by-step explanation:

Given

A decreasing geometric sequence

Ratio = \frac{m}{7}

Required

Determine the possible integer values of m

Assume the first term of the sequence to be positive integer x;

The next sequence will be x *  \frac{m}{7}

The next will be; x *  (\frac{m}{7})^2

The nth term will be x *  (\frac{m}{7})^{n-1}

For each of the successive terms to be less than the previous term;

then \frac{m}{7} must be a proper fraction;

This implies that:

0 < m < 7

<em>Where 7 is the denominator</em>

<em>The sets of </em>0 < m < 7<em> is </em>\{1,2,3,4,5,6\}<em> and their are 6 items in this set</em>

<em>Hence, there are 6 possible integer</em>

What is this, x-8 all over 3=3
inysia [295]
You mean (x-8)/3 = 3 ...right?

You would multiply both sides by 3.
Then, add 8 to both sides.

x=17
