Answer:

1/2

Step-by-step explanation:

It is a independent problem. Flipping a head the first time will not affect the other results therefore it is still one half.

Use a division ladder to find the gcf of 20 and 50.

Usimov [2.4K]

Gcf refers to a digit which can divide both numbers without a remainder
20|50 is divisible by 2 to become 10|25 and then divisible by 5 to become 2|5
=2×5
Gcf= 10

What is the explicit formula for this sequence?

jonny [76]

Answer:

$\text{C. }a_n=-8+(n-1)5$

Step-by-step explanation:

The explicit formula for an arithmetic sequence is given by $a_n=a_1+(n-1)d$ , where $a_n$ is the $n$ th, $a_1$ is the first them of the sequence, and $d$ is the common difference.

In the given sequence -8, -3, 2, 7, we can see that we're adding 5 to each term. Therefore, the common different is positive five (+5). We can also identify the first term is -8. Therefore, we have:

$a_1=-8$
$d=5$

Thus, the explicit formula for this sequence is:

$\boxed{a_n=-8+(n-1)5}$
