Step-by-step explanation:

Given

$P_1=$ Probability of clearing exam in 1 st attempt=0.5

$P_2=$ Probability of clearing exam in 2 nd attempt=0.7

$P_3=$ Probability of clearing exam in 3 rd attempt=0.8

Probability that she passes the exam $=P(1 st\ attempt)+P(1\ fail)\cdot P(2\ pass)+P(1\ fail)\cdot P(2\ fail)\cdot P(3 rd pass)$

$P=0.5+0.5\times 0.7+0.5\times 0.3\times 0.8=0.97$

(b)P(Pass qualification on 2nd try|passes qualification)

P(Pass qualification on 2nd try|passes qualification) $=\frac{P(fail\ on\ 1 )\cdot P(pass\ in\ 2nd)}{P(passes)}$

P(Pass qualification on 2nd try|passes qualification) $=\frac{0.5\times 0.7}{0.97}=0.3608$

Find the angle of RMQ.

faust18 [17]

Answer:

Step-by-step explanation:

since there is a bisector that makes the two angles equal. you first need to find x then with x you can add the angles to get the biggest angle witch is RMQ

2x+1 = 4x-9

1=2x-9

10=2x

5=x

x=5

RMQ=2x+1+4x-9

RMQ=2(5)+1+4(5)-9

RMQ=10+1+20-9

RMQ=11+11

RMQ=22

RMQ=16
