Answer:

The sum of first five term of GP is 19607.

Step-by-step explanation:

We are given the following in the question:

A geometric progression with 7 as the first term and 7 as the common ration.

$a, ar, ar^2,...\\a = 7\\r = 7$

$7, 7^2, 7^3, 7^4...$

Sum of n terms in a geometric progression:

$S_n = \displaystyle\frac{a(r^n - 1)}{(r-1)}$

For sum of five terms, we put n= 5, a = 7, r = 7

$S_5 = \displaystyle\frac{7(7^5 - 1)}{(7-1)}\\\\S_5 = 19607$

The sum of first five term of GP is 19607.

Verification:

$2801\times 7 = 19607$

Thus, the sum is equal to product of 2801 and 7.

The number of games a baseball team has won in each of the ten seasons is as follows:

nevsk [136]

Answer:

The mean = 14.3. median = 15.5 and the range = 10.

Step-by-step explanation:

10, 16, 19, 13, 12, 17, 16, 15, 9, 16

The mean = sum of the 10 numbers / 10 = 143/10 = 14.3.

Find the median by arranging in ascending order:

9, 10, 12, 13, 15, 16, 16, 16, 17, 19

The median is the mean of the 2 middle numbers = (15 + 16)/2

= 15.5.

The range = highest - lowest number = 19 - 9 = 10.
