2,5, 25/2, ... find the 10th term

notka56 [123]

Answer:

The $10^{th}$ term of the given sequence

$t_{10} = \frac{5^{9} }{2^{8} }$

Step-by-step explanation:

Step(i):-

Given sequence 2 , 5, $\frac{25}{2}$

First term a = 2

The difference of given geometric sequence

$d = \frac{r_{2} }{r_{1} } = \frac{5}{2}$

Step(ii):-

The $n^{th}$ term of the given sequence

$t_{n} = ar^{n-1}$

The $10^{th}$ term of the given sequence

$t_{10} = (2)(\frac{5}{2} )^{10-1}$

$t_{10} = (2)(\frac{5}{2} )^{9}= \frac{5^{9} }{2^{8} }$

What is 1 fifth divided by 6

IgorC [24]

1/5 divided by 6

6 = 6/1

When dividing fractions, we follow a rule called "Keep, change, flip."

It then becomes: 1/5 * 1/6 = 1/30

1 fifth divided by 6 equals 1/30

20/28 = 5/7

Step-by-step explanation:

Step 1 :

Total number of students in the algebra class is 28

Given that the number of students who play neither sport = 8

Step 2 :

Probability that a student randomly chosen does not play any sport is obtained by number of students who play neither sport/ total number of students

Hence probability is 8/28

Step 3 :

The probability that a student randomly chosen plays either basketball or base ball = 1 - 8/28 = 20/28 = 5/7
