Subtract sides -7
Thus ;
So the correct answer is (( A )) .
Answer:
∠1=140
Step-by-step explanation:
∠1=∠3 ( corresponding angles)
20x+60=30x+20
-20x+30x=60-20
10x=40
x=4
∠1=20x+60=20(4)+60=140
Answer:
20 m/s
Step-by-step explanation:
Speed = distance/time
(100 m)/(5 s) = 20 m/s
Answer:
0.9973
Step-by-step explanation:
Given :
Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481
1 - p = 0.481
n = 9
Probability that atleast one is girl
Usingbthe binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
USing the binomial probability calculator :
p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)
p(x ≥ 1) = 0.9973 ( from calculator).
