Answer:
1. 27.5 in.^2
2. 360 in.^2
Step-by-step explanation:
1.
A = bh/2
A = (4 + 7)(5)/2
A = 27.5 in.^2
2.
A = bh/2
A = (35 + 13)(15)/2
A = 360 in.^2
A=x+y+z/3
a-x=y+z/3
a-x-z/3=y
so y=a-x-z/3
Answer:
Probability of obtaining 6H and 4T = 0.2051
Step-by-step explanation:
Since for a fair coin,
Probability of obtaining Head = 0.5
p = 0.5
q = 1-p = 0.5
Probability of obtaining 6H and 4T = 10C6 (p)^6(q)^4 = 210*0.5^6*0.5^4
P(6H, 4T) = 0.2051
I would say C 9 because the only term with a 9 in it is 9f4g
