The relative frequency with which the coin will land on tails 12 of those times willl be 48%. None of the given options are correct.

<h3>What is the formula for calculating the joint relative frequency?</h3>

Assume you need to compute the joint relative frequency of a certain category inside a larger category. Then there's the proportion of that specific category's frequency to the total frequency of that large category.

If the experiment is run 25 times and we receive tails 12 times, the relative frequency of receiving tails is as follows:

\rm R = \frac{12}{25} \times 100 \\\\ R = 48 \%

Hence, the relative frequency for the given condition will be 48%.

To learn more about the relative frequency, refer to brainly.com/question/12165221.

0.8 is 10 times as great as what decimal
kondor19780726 [428]
When we say that 2y is 2 times greater than y, this means that if we divide 2y by 2 we will get the y.

Similarly, to know the decimal that is less that 0.8 by 10 times, simply divide 0.8 by 10 as follows:
decimal = 0.8 / 10 = 0.08

This means that 0.8 is 10 times larger than 0.08

In a game, a player earns 100 points for each question answered correctly and earns -30 points for each question answered incorr
REY [17]

The general expression is 130 x - 600 and total points scored by the player is 1220

A) Let the number of correctly answered questions be x.

∴ Number of incorrectly answered questions will be 20 - x.

+ 100 points is awarded for each question answered correctly while -30 points is awarded for each question answered incorrectly.

Thus, the general equation becomes

= 100x - (20 - x)(-30)

= 100x +30x - 600

= 130x - 600

Thus the general expression becomes 130 x - 600

B)  The player answers 14 questions correctly, thus x = 14

Substituting the value of x =14 in the general equation we get,

= 130(14) - 600

= 1820 - 600

= 1220.

Thus the total points scored by the player will be 1220
