3*x+3*12
3x+36
You just need to do the multiplication separately !
50+ (100x99)
50 + 9900
9950

2sin3x-1=0
sin3x=1/2
sinx=1/2, x=pi/6, 5pi/6
3x=arcsin(1/2)
x=1/3*pi/6
[x=pi/18]
Answer:
Step-by-step explanation:
Given that you choose at random a real number X from the interval [2, 10].
a) Since this is a contnuous interval with all number in between equally likely
E = probability for choosing a real number is U(2,10)
pdf of E is
b) P(X>5) =
For
P(X<5 or x>7) = 1-P(5<x<7)
=
