In a class of 160 students, 90 are taking math, 78 are taking science, and 62 are taking both math and science. What is the probability of randomly choosing a student who is taking only math? 56%

39%

49%

74%

HURRY PLEASE

56%

Step-by-step explanation:

Your question is asking for students who are taking only math. Of 160 students, 90 are taking only math. This gives you the proportion of = 0.56. To find percents, just multiply it by 100 to get 56%.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
