Ierofanga [76]

Answer:

Step-by-step explanation:

a) P(X > 6) = (9.5-6)/(9.5-5.5) = 3.5/4 = 0.875

b) P(X < 7) = (7-5.5)/(9.5-5.5) = 1.5/4 = 0.375

c) E(X) = (9.5+5.5)/2 = 7.5

Standard deviation = (9.5-5.5)/sqrt(12) =4/3.46 = 1.154

P= 1.156*2/(9.5-5.5) = 2.308/4 = 0.577

d) P(X > t) = 0.25

(9.5-t) /(9.5-5.5) = 0.3

9.5-t = 1.2

t = 9.5-1.2 = 8.3

Answer:
1). Y=4x-2
2). Y= 2x-1

Explanation:
For the first graph
Slope = 4
Y intercept = -2
Y=mx+b
Y= 4x-2
For the second graph
Slope = 2
Y intercept =-1
Y=mx+b
y= 2x-1
