Mr. stewart has 26 students in his class. ten of his students are girls. if mr. stewart writes each student's name on a small strip of paper, puts all the paper strips into a hat, and then pulls out one strip without looking, what is the probability that he will pull out a boy's name?

8/13

Step-by-step explanation:

Step 1 : Write all the data

Total number of students = 26

Number of girls in class = 10

Number of boys in class = 26-10 = 16

Step 2 : Find the probability

Probability of pulling out a boy's name = number of boys in class

                                                             Total number of students in class

= 16/26

Simplify :

16/26 = 8/13

where is the picture

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
