Hi Veracity,
Answer:
(2 + i) = 2
Step-by-step explanation:
Multiply the denominator and numerator by the conjugate,
= 
Combine Like Terms,
= 
Simplify,
= 2 + i
Hope This Helps :)
−129=−48−n
Simplify:
−129=−48+−n
Flip the equation.
−n−48=−129
Add 48 to both sides.
−n−48+48=−129+48
−n=−81
Divide both sides by -1.
−n/−1 = −81/−1
n=81
Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
