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
Answer:
Coordinates of X is (7/2,9/2)
Coordinates of C is (6,7)
Explanation:
x is the midpint of DB and AC
coordinates of X = ( (5+2)/2 ,(6+3)/2)
= (7/2,9/2)
Coordinates of X is (7/2,9/2)
Let (a,b) be the coordinates of C.
Then,
coordinates of x = ((a+1)/2, (b+2)/2)
(7/2,9/2) = ((a+1)/2, (b+2)/2)
Hence,
7/2=(a+1)/2
7=a+1
a = 6
9/2 =(b+2)/2
9 =b+2
b =7
Coordinates of C is (6,7)
