Nicole is rolling a dice for a probability project. What is the theoretical probability that she will roll a 1 or a 4? Write you
Alex777 [14]

Answer:

\frac{1}{3}

Step-by-step explanation:

Given: Nicole is rolling a dice for a probability project

To find: theoretical probability that she will roll a 1 or a 4

Solution:

Theoretical probability expresses the chances that something will occur. It is equal to the number of favorable outcomes divided by the total number of outcomes.

Total number of outcomes = 6

Theoretical probability that she will roll a 1 or a 4 = \frac{1}{6} +\frac{1}{6} =\frac{2}{6}=\frac{1}{3}

Formula in the form y=mx+b models the value, y, of a new car x years after the initial purchase in 2010. Would you expect b to b
Tom [10]

Answer:

positive

Step-by-step explanation:

The equation of a line modeling the price of a car over the years from its initial purchase is to be a line with negative slope "m" due to the fact that the price of the car drops with the years, but for sure the price at the time of purchase (which is the zero in the horizontal x-axis) should be the largest value the car would have (the purchase price) This is actually the y-intercept "b", clearly a positive number.
