A city held a bike parade. 52 bikers rode in the parade, and 8 of them rode a fixed-gear bicycle.

Vedmedyk [2.9K]

Answer:

$\frac{2}{13}$

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is $\frac{8}{52}$

This can be simplified by dividing both the numerator and denominator by 4:

= $\frac{2}{13}$

So, the probability is $\frac{2}{13}$

What is the recursive rule for an=4n−1? a1=4;an=an−1−1 a1=3;an=an−1+4 a1=−1;an=an−1+4 a1=3;an=an−1−1

navik [9.2K]

Plug in n = 1 into the nth term formula
a(n) = 4n-1
a(1) = 4*1-1
a(1) = 3
So the first term is 3

The second term will be 7 because we add on 4 each time, as indicated by the slope of 4. This is also known as the common difference.

So the nth term is found by adding 4 to the (n-1)st term, in other words,
a(n) = a(n-1)+4

----------------------------------------------------------------------------

In summary, the answer is
a1=3; an=an-1+4
which is choice B

What is the next number 486, 162, 54, 18

Lesechka [4]

The pattern is to divide by 3

486 ÷ 3 = 162
162 ÷ 3 = 54
54 ÷ 3 = 18
18 ÷ 3 = 6

The next number is 6
