Step-by-step explanation:
Answer:
x = 16
Step-by-step explanation:
If the figure is a parallelogram, the opposite sides are the same length
3x+20 = 5x-12
Subtract 3x from each side
3x+20 -3x = 5x-12-3x
20 = 2x-12
Add 12 to each side
20+12 = 2x-12+12
32 = 2x
Divide each side by 2
32/2 = 2x/2
16 =x
Answer:
a) 1504
b)
Step-by-step explanation:
A
a. no of people that are male = 42
b. no of people that study biology = 34
c. no of people that do both = 1428(42 × 34)
d. no of people that are Male or study biology or both = 42 + 34 + 1428= 1504
B.
a.no of people that are male or female = 90
prob(male) = 14 ÷ 90
= 0.16
b. prob(bio) = 34 ÷ 34
= 1
c.prob(both) = 0.16
d. prob(all) = 0.16 + 1 + 0.16
= 1.32
