You flip a coin and roll the 20-sided figure. Find the probability of flipping tails and rolling at least a 14. The probability is

Please help asap!

7/40

Step-by-step explanation:

1) First of all, we calculate the probability to flip tail in the coin.

Since the coin has only 2 outcomes (head or tail) and the successfull event is just one of them (tail), the probability of getting a tail when flipping the coin is:

2) Now we calculate the probability of rolling the dice and obtaining at least 14.

Here the successfull events are all the numbers from 14 to 20, so the following numbers:

14, 15, 16, 17, 18, 19, 20

So there are 7 successfull outcomes.

The total number of outcomes is instead 20, so the probabiity of rolling at least 14 is:

The two events 1) and 2) are independent events (they do not depend on each other); the combined probability of two independent events can be calculated as the product between the individual probabilities, so in this case:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
