6 4/11 x2 1/12 Estimate the product
Aleksandr-060686 [28]

Answer:

The estimated product is 12.

Step-by-step explanation:

When rounding fractions, we can round them to 0, 1/2 or 1. 6 4/11 can be rounded to 6 since 4/11 isn't near the half of 11. 2 1/12 can be rounded to 2 since 1/12 is obviously close to 0. 6 x 2 = 12. The estimated product is 12.

What is the sum of the first seven terms of the geometric series? 3 12 48 192 ...
Ad libitum [116K]

Hence, the sum of the given GP is 16347

<h2>What is a series?</h2>

a series is the cumulative sum of a given sequence of terms. Typically, these terms are real or complex numbers, but much more generality is possible.

<h3>How to solve?</h3>

we can identify from the given geomertric series.

first term = a(say) = 3

geometric factor of progression = r(say) = 4

Sum of the first 7 terms = a(\frac{r^n-1}{r-1})          ,where n is 7

Sum = 3(\frac{4^7-1}{3}) = 16348-1

       = 16347

Hence, the sum of the given GP is 16347.
