(Please answer it correctly please please show work )Thalia tosses a fair number cube with faces numbered 1 to 6. Which is a rea

anastassius [24]

Answer:40

Step-by-step explanation:

On a fair die, each face has a 1/6 chance of landing on each toss.

5 and 6 are the only faces greater than 4, therefore there is a 1/6 + 1/6 = 2/6 chance of the die landing on a number greater than 4 for each toss.

Multiply the probability by the total number of tosses to get the number of tosses that are greater than 4.

120 * (2/6) = 240/6 = 40

Approximately 40 tosses will land on a number greater than 4.

A large railroad car is filled with 1745 gallons of milk. The car springs a leak in the bottom, and milk starts dripping out at

jeka57 [31]

Answer:

585.98 miles

Step-by-step explanation:

We need to convert 1745 gallons to mL.

We know 1 gallons = 3785.41 mL

So 1745 gallons = 1745 * 3785.41 = 6,605,540.45 mL

Leaks are at 204.84 mL/sec, so it will take:

6,605,540.45/204.84 = 32,247.32 seconds

In hours, that is:

32,247.32/(60*60) = 8.96 hours

Now, since train is travelling at 65.4 miles per hour, in 8.96 hours, train will approximately travel:

65.4 * 8.96 = 585.98 miles
