Answer:
a. 0.69
b. 0.13
c.0.56
Step-by-step explanation:
Total number = 100
a) either means students with either option are valid
69/100 = 0.69
b) both means each student has done both math and english
=13/100 = 0.13
c) Only one means has done one subject and not both classes. We have 23 for math and 33 for english (this is according to your venn diagram)
23+33=56
one subject =56/100 = 0.56
Answer:
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
Therefore, ∠ABC + ∠BAC + ∠BCA = 180°
⇒ 42 + 64 + ∠BCA = 180°
⇒ ∠BCA = 180 - 42 - 64
Area of a rectangle = length * width.
So L * w = 864
But w = 2/3L
So we have L * 2/3L = 864
L^2 = 864 * 3/2 = 1296
L = âš 1296
L= 36 and width = 2/3 * 36 = 72/3 = 24
Dividing the number of balloon animal per the time he takes to make them you get an average of how many animals per minute Fred the clown can make.
20/15=1,3 animals per minute
Since 0,3 is not a complete animal, the correct answer would be "Fred the clown can make 1 animal in 1 minute"
