You put the names of all the students in your class in a paper bag. there are 16 boys and 18 girls. if you draw a name at random, what is p(boy’s name)?

Step-by-step explanation:

The probability of drawing a boy's name is found in:

number of boys/total number of students

Our ratio then is

16/16+18 which is

16/34 which reduces to

8/17

As a percentage, it would be about 47%

Total students = 16 + 18 = 34

16 boys

Probability of picking boy = 16/34

Which reduces to 8/17

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
