A coin is flipped 70 times and lands on tails 21 times. what is the relative frequency of the coin landing on tails?
1 answer:
Given,
Total number of time coin is flipped = 70
number of time coin lands on tail = 21
<h3>What is Relative Frequency?</h3>A relative frequency indicates how often a specific kind of event occurs within the total number of observations. It is a type of frequency that uses percentages, proportions, and fractions.
To find: relative frequency of coin landing on tail.
= 21 / 70
= 3 / 10
Relative frequency = 3 / 10 × 100
= 30%

The value remains under the radical is 8 ⇒ last answer
Step-by-step explanation:
Let us revise how to write the exponent as a radical
can be written as
- To simplify the radical factorize the base "a" to its prime factors
Example:
,
- Factorize 54 into prime factors ⇒ 54 = 2 × 3 × 3 × 3 =
- 2² can not go out the radical because 2 is less than 3 not divisible by 3
can go out the radical because 6 is divisible by 3, then divide 6 by 3, so it will be 3² out the radical
Now let us solve your problem
∵
- Factorize 1250 to its prime factors
∵ 1250 = 2 × 5 × 5 × 5 × 5
∴
∴
∵ 2³ can not go out the radical because 3 < 4 and not divisible by it
- can go out the radical because 12 can divided by 4
∵ 12 ÷ 4 = 3
∴ can go out the radical as 5³
∴
∴
∴ The value remains under the radical = 8
The value remains under the radical is 8
