I need help ASAP Is 3, 4, 6, 9, 13, 18,… an arithmetic sequence? Why or why not

Mathematics

kirza4 [7]4 years ago
4 0

Answer:

No

Step-by-step explanation:

No, this is not an arithmetic sequence because it goes up by a different number each time.

An example of an arithmetic sequence would be,

3, 5, 7, 9...

because it increases by 2 each time.

A geometric sequence is multiplied or divided by a set number each time.

An example would be,

2, 4, 8, 16...

because it is multiplied by 2 each time.

Since the block is a cube, the dimentions from corner to corner equal all the same, as long as the pieces are equal, which in this case, they are. :) So basically what you need to do is find the perimeter of one side of the cube, and that's the answer.

A 12-member jury is to be selected from 15 men and 13 women. Find the probability that this jury has 6 or 7 males.
Bas_tet [7]

Answer:

The right solution is "0.5545".

Step-by-step explanation:

According to the question,

The probability of having 6 or 7 males will be:

= P(6 \ males)+ P(7 \ males)

= \frac{15_C_6\times 13_C_6}{28_C_{12}} + \frac{15_C_7\times 13_C_5}{28_C_{12}}

= \frac{5005\times 1716+6435\times 1287}{30421755}

= \frac{16870425}{30421755}

= 0.5545
