-4 x 8= -32+3=-29. -29/8= -3.625
Answer:
Step-by-step explanation:
a) Complete the table
Monday Tuesday Wednesday Total
Female 21-14=7 38-13-7= 18 13 38
Male 14 33-18= 15 26-13 =13 80-38=42
Total 80-33-26= 21 33 26 80
b) P(the student is a female) = 38/80= 0.475
c) P(the student visited the library on Tuesday) = 33/80= 0.4125
Bc = 24
Ad = 5y-1
5 times what is 25?
5 x 5 = 25
25 - 1 = 24
Therefore Y = 5
5(5) - 1 = 24
