<span>Answer:
The notation for the uniform distribution is
X ~ U(a, b), where a = the lowest value and b = the highest value
In your case, X ~ U(66,89)
µ = (b+a)/2
Ď = (b-a)²/12
In this case, a = 66 and b = 89
Thus,
µ = (89+66)/2 = 77.5
Ď = (89-66)²/12 = 44.0833
Then, because we now know the true/population µ and Ď, we can use z-scores.
z = (X-µ)/Ď
In our case, X = 71. So,
Z = (X-µ)/Ď
Z = (71-77.5)/44.0833 = -0.15
P(Z>-0.15) = P(Z<0.15) = 0.5596</span>

Answer:
16.67
Step-by-step explanation:
Step 1: We make the assumption that 20 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=20.
Step 4: In the same vein.
Step 5: This gives us a pair of simple equations
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
Step 7: Taking the inverse (or reciprocal) of both sides yields
Step-by-step explanation:
H(x)=

If g(x) values =0, h(x) will be undefined.
So f(x)=0, h(x) will be undefined.
Zo find values of f(x) equal 0.
That is when x=2. So the answer to first solution is 2.
h(x) is negative when (-oo, -3) U (2,oo)
