A number cube is rolled and a coin is flipped. Predict how many times you would get heads and a number less than 3

First the probability of getting a heads and a number less than three
well the probability of getting heads is 1 in 2 and the probability of getting a number less than 3 is 2 in 6. To find the probability of them occurring together you just multiply 1/2 * 1/3 = 1/6. Now find 1/6 of 240 and that winds up to be 40

5 0

It would be about 25 percent of the time i believe
but i would need the total number of times they were flipped/rolled to tell you the number of times it is.

Answer:

$x(35)\approx 11.8$

Step-by-step explanation:

Modeling With Functions

We have a table of values of speeds vs distance taken for a car to stop. We are required to find a model that uses the square root and fits the given data to predict other values of d as a function of v.

By the nature of the problem, we can know that for v=0, d must be 0 too. So our model won't include a vertical shift or independent term. Being v the speed of the car and x the distance it takes to stop, we use the following model

$x(v)=A\sqrt{v}$
