Answer:
The probability that Justin will practice soccer this evening is 16%.
Step-by-step explanation:
The probability that John will practice soccer is given by the product of the probability that it won't snow and the probability that he'll practice soccer. This is shown below:
practice soccer = (1 - 0.6)*0.4
practice soccer = 0.4*0.4
practice soccer = 0.16
The probability that Justin will practice soccer this evening is 16%,
Answer:
303.5 pounds
Step-by-step explanation:
If all the pallets weigh 4,856 together and each pallet weighs the same since they have equal cement and cement weight is equal, then 16 pallets will weigh 303.5 pounds each.
This is true because 4,856 / 16 = 303.5.
Problem 4
<em>A</em>
If he is staying in the same place km for 1/2 hour, you can assume he's eating lunch or something. He hasn't moved at all, so his speed = distance over time = 0/(0.5) hours = 0
0 = answer
<em /><em>B
</em>Watch out for this. It's a little bit nasty. He starts out at 20 km He ends up at 0 km. It means he is going back to were he started from. If it said velocity, you'd have a problem.
<em>
</em>The time taken is 1.5 to 3 hours = 1.5 hours
His speed is d/t
<em>His speed is 20/1.5 = 13.33 km/hr.
</em>Speed = total distance / total time
total time = 3 hours.
Total distance = 40 km which is what the odometer would show.
Speed = 40 km/3 hours = 13.33 km/hour
<em>C
</em>You could just read the graph. He is 10 km from home.
