Thirty percent of check engine lights turn on after 100,000 miles in a particular model of van. the remainder of vans continue to have check engine lights that stay off.

simulate randomly checking 25 vans, with over 100,000 miles, for check engine lights that turn on using these randomly generated digits. let the digits 1, 2, and 3 represent a van with check engine light that turn on.

96408 03766 36932 41651 08410

approximately how many vans will have check engine lights come on?

7

Step-by-step explanation:

Given:

Simulation of randomly checking 25 vans, with over 100,000 miles=

                                                96408 03766 36932 41651 08410

Here  the digits 1, 2, and 3 represent a van with check engine light that turn on.

Approximately how many vans will have check engine lights come on?

From the above given data the digits 1, 2 and 3 that represented the particular model of van having check engine lights on are repeated 7 times in the simulation of randomly checking 25 vans, with over 100,000 miles

Hence 7 vans will have check engine lights come on!

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

answer: i guess 5 units?
