Answer: a) 7
b) c
<u>Step-by-step explanation:</u>
Inverse is when the x's and y's are swapped.
a)
f(7) = 22 means ..... when x = 7, then y = 22
The inverse is ..... when x = 22, then y = 7
b)
f⁻¹(f(c)) means ...... when x = f(c), then y = c
The reverse of the inverse is ..... when x = c, then y = f(c)

Answer:
For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16.
Step-by-step explanation:
Here, P(x > 40) = 0.16
a). P(x < 40) = 1 - P(x > 40)
= 1 - 0.16
= 0.84
b). P(x < 20) = 1 - 
= 1 - {P(20 ≤ X ≤ 40) + P(X > 40)}
= 1 - (0.15 + 0.16 )
= 1 - 0.31
= 0. 69
c). P(x = 40) = 0; The probability that a continuous variable assume a particular value is zero.

Answer:
4.5
Step-by-step explanation:
0.5p-3.45=-1.2
add 3.45 to -1.2 which would leave the equation to look like
0.5p=2.25
then divide 0.5 to both sides cancelling 0.5 leaving the answer to be
p=4.5
