Freddy’s batting average is 400. That means the probability of him getting a hit any time he is at bat is 2 out of 5. Estimate the probability that it will take at least three times at bat for him to get a hit. Let the digits 0-3 represent hits and 4-9 represent not getting a hit. Perform 20 trials of a simulation using the random digits in the table below to determine your answer.
Answers
Answer 1
Answer:
Since the probability of a hit is 2/5, not getting hit has the probability (1-2/5)=3/5. We deduce that the probability of the event: "that it will take at least three times at bat for him to get a hit" is the following:
When you divide a whole number by a fraction with a numerator of 1, explain how you can find the quotient?

you take the whole number and put it in a fraction over 1 then divide by flipping the second fraction and multiplying
3. An airplane flies 105 miles in ½ hour. How far can it fly in 1 ¼ hours at the same rate of speed?
Answers
262.5 miles explanation 1/4 is half of 1/2 so 52.5 is half of 105 and then 210 for an hour of travel
Answer:
105 at 30 min.
x at 75 min.
105 mph x 2 = 210 mph at one hour
There is still 15 min to go soooo...
210/4 = 52.5
210 + 52.5 = 262.5 mph for 75 min
Check by dividing
262.5/75=3.5
The soccer field measures 80 meters by 120 meters. Which is the correct unit of measurement to figure out how much fertilizer is needed to cover the field?
Answers
To find out the area of the field, you just need to multiply 80 meters by 120 meters.
80 meters * 120 meters = 9600 meters²
Therefore, the unit of measurement to figure out how much fertilizer is needed to cover the field is meters².
