This is a geometric sequence with first term 3 and a common ratio of -5/3.

Using the sum of a geometric series formula,

$\frac{3(1-(-5/3)^{7}}{1-(-5/3)} \approx \boxed{41.31}$

B(n)=-8-2(n-1)<br> Find the 9th term

TEA [102]

Answer:

The 9th term will be -24

Step-by-step explanation:

The 9th term will be equal to

$b_{n}$ = - 8 - 2(n - 1)

$b_{9}$ = - 8 - 2(9 - 1)

$b_{9}$ = - 8 - 18 + 2

$b_{9}$ = - 24

A person suspects a standard number cube is not so standard. Another person rolls this cube 100 times, and it lands on a six 42

Ksju [112]

Answer:

The chance of an average six-sided number cube landing one one number is 1/6, or approximately 16.67%. When rolling a number cube 100 times, the average number of times it lands on any specific number should be fairly close to 16.67.

A 6 being rolled 42 times and 33 times means that it is <em>very likely</em> not to be a standard number cube. Although we cannot know for certain, the chance of this happening is very low.
