So the first thing you do is you divide 1024 by 256. you will come out with the answer of 4. it takes 4 seconds to download 1 megabyte. but, it takes 4 megabytes, so you need to multiply 4 by 4. you will get 16. it takes 16 seconds to download 1 song.
to figure out how many songs Lindy can download in 2 hours, you multiply 60 by 60. you will get an answer of 3600. there are 3,600 seconds in an hour. now to find out how many are in 2 hours you multiply 3,600 by 2. you will get a sum of 7,200
now to figure out how many songs Lindy can download in 2 hours, you divide 7,200 by 16. you will come out with a quotient of 450.
Lindy can download a total of 450 songs in the space of 2 hours.
Answer:
The probabilities that a flight is more than 140 minutes would be 32.2%.
Step-by-step explanation:
Given that a trip between New York and Chicago lasts between 120 and 150 minutes, with probabilities uniformly distributed within that time range, to calculate the probabilities that the trip lasts more than 140 minutes, we must perform the following calculation:
First, determine the range of minutes available for arrival. Thus, between 120 and 150, including both ends, there is a 31 minute difference (150-119). Therefore, since the 100% arrival probability is evenly distributed between these minutes, each minute has a 3.22% probability that the plane will arrive at that time (100/31 = 3.22).
Therefore, since the question points to a journey of more than 140 minutes, we must consider the time from the 141 minute journey, that is, 10 minutes between 141 and 150. Thus, the probabilities that the trip lasting more than 140 minutes will be 32.2%.
I THINK the slope is -4,6 and the midpoint is (0,1)
D, because if you apply a dilation of three to a line with a length of 6, you'd multiply the two, getting an answer of 18. You know to multiply since the scale factor is a number larger than 1
