Answer:

1 in 5 (25% chance)

Step-by-step explanation:

The probability of choosing a blue marble the first time is 1 in 2, and then choosing it again would be 2 in 5, and 1:2 times 2:5 = 2:10. there is a 20% chance, or 1 in 5 chance, that a blue marble is drawn.

761280 / 29280 = 26 years

292800 / 29280 = 10 years

Write a scenario that could work for the following line of best fit: y = 0.2x + 7.6. Explain the slope and intercept in this con
Ipatiy [6.2K]
In this question we know what the “y-intercept is,so if we go to our graph we can easily just plot the point 7.6 on the y axis of a number line. It also gives you the slope in decimal form so we would want to convert that from 0.2 to 1/5. And remember the slope is how many places you move to get to the next point on the number line. So from the point 7.6 we would move up 1 over 5 to the right because it is a positive number. Your line should run across the upper segment of the number line and your line should make a 20 to 30 degree angle shift
