Answer:

400 ping pong balls

Step-by-step explanation:

Let the total number of ping pong balls =x

Out of x ping pong balls, 80 are marked with a blue dot

Out of 80 ping pong balls, 16 are marked with a blue dot.

Expressing it as a ratio:

x:80=80:16

$\frac{x}{80}=\frac{80}{16}\\ 16x=80X80\\x=6400 \div 16\\x=400$

There are an estimate of 400 ping pong balls in the container.

Answer:

Converges to -25.

Step-by-step explanation:

$\sum_{k=1}^{\infty} -5 \cdot (\frac{4}{5})^{k-1}$ converges since $r=\frac{4}{5}$ .

The sum is given by $\frac{a_1}{1-r}$ where $a_1$ is -5.

$\frac{-5}{1-\frac{4}{5}}=\frac{-5}{\frac{1}{5}}=-5(5)=-25$ .
