As you must be knowing, the formula for x successes in n trials in a binomial distribution where p is the probability of a success in a single trial & q = 1 - p is the probability of failure in a single trial is
<span>P(x) = nCx*p^x*q^n-x </span>
<span>For this problem, what you have to do is to find </span>
<span>x*P(x) for all values of x from 0 to 15, using </span>
<span>p = 0.3 & q = 4/5 , i.e </span>
<span>0*P(0) + 1*P(1)+...15*P(15) = </span>
<span>0*15C0*(0.3)^0*(4/5)^15 + 1*15C1*(0.3)^1*(4/5)^14 +.... </span>
<span>15*15C15*(o.3)^15*(4/5)^0 </span>
since the angles are at a same slope the equation basically turns into this
m+20=100 to find the answer subtract.
100-20=80
80 is the answer
The answer answer is x=5 (y-3)
Answer:
33.55°
Step-by-step explanation:
let alpha be X
sin x= √11/6
sin x= 0.5527
x= sin-1 0.5527
x= 33.55°
