Question seem incorrect because 60%,50% and 20% sum up to more than a 100% therefore we've made a little correction

Answer:

0.8

Step-by-step explanation:

Probability = number of favorable outcomes/number of outcomes

Given that 30% are entertained by reading books

50% are entertained by watching TV

20% are entertained by reading books and watching TV

The probability that a person will be entertained by books or TV =

30/100+50/100= 3/10+5/10

=8/10

=0.8

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which
ra1l [238]

Total number of times she flipped a coin =200.

Total number of heads in the experiment=92

Total number of tails in the experiment=108

Therefore probability of the coun landing heads up in this experiment is 0.5

In the above experiment, the probability of the coin landing heads up is

P(H)= 92/200 = 0.46

In the above experiment, the probability of the coin landing tails up is P(T) = 108/200 = 0.54

The ratio obj represent the experimental probability of the coin landing heads up in this experiment

Therefore the correct option is 1.

When x=3, y=16 and when x=6, y=8. Which inverse variation equation can be used to model this function
MakcuM [25]

Inverse variation equations take the following form:

y = a/x, where a is some constant

We know x=3, y=16 and x=6, y=8 satisfy the equation.

Let's find the value of a.

16=a/3

Multiply both sides by 3

16*3 = a

48 = a

Thus, the equation is:

y = 48/x

You can use the other values of x and y to test, but I'm sure this is the correct equation. :)

A number, y, is equal to the difference of a larger number and 3. The same number is one-third of the sum of the larger number a
mariarad [96]

Answer:

The two equations are

y = x - 3 and

3y = x + 9

Step-by-step explanation:

The options are not well stated. I'll answer the question without the options but however, my answer will be a reflection of one of the given options.

Given:

2 statements

Required

Write equivalent of both statements as equations

Let the large number be represented by x.

From the first statement (y, is equal to the difference of a larger number and 3)

Difference means minus (-); so, this statement is represented as follows to give us the first equation:

y = x - 3

From the second statement (The same number is one-third of the sum of the larger number and 9).

This is also represented as follows to give us the second equation

y = ⅓(x + 9)

Multiply both sides by 3

3 * y = 3 * ⅓(x + 9)

3y = x + 9

So, the two equations are

y = x - 3 and

3y = x + 9
