The probability that a person will take longer than 21 days to pass it is 0.12
<u>Explanation:</u>
Given:
Mean time, μ = 14 days
Standard deviation, ρ = 6 days
Let x be the time to pass the kidney stones.
Probability that a person will take longer than 21 days to pass it.
We need to find z score first
Z score = 
Z score = 
= 1.166
Probability that a person will take longer than 21 days to pass it = P(x > Z)
= P(x > 1.16)
= 0.12
Therefore, the probability that a person will take longer than 21 days to pass it is 0.12

Answer:
c) x^2 +16x + 64 = 25
Completed question;
Monica is solving a quadratic equation. She wants to find the value of x by taking the square root of both sides of the equation. Which equation allows her to do this?
a) x^2 - 10x - 25 = 14
b)x^2 + 160x +26 = 19
c) x^2 +16x + 64 = 25
d) x^2 - 9x + 81 = 34
Step-by-step explanation:
To solve a quadratic equation by taking the square root of both sides, we should be able to express the equation in the form;
(x + a)^2 = b^2
Or
(x - a)^2 = b^2
From the above options,
Option C looks to give the desired form
x^2 + 16x + 64 = 25
Which can be further factorised as;
(x + 8)^2 = 5^2
(Note: a = 8 and b = 5)
square root of both sides;
x + 8 = +/- 5
x = +5-8 = -3 (solved)
or
x = -5-8 = -13 (solved)
Answer:
5^12 or (244140625)
Step-by-step explanation:
I've always hated exponents but the way I visualize this is essentially taking 5^4 and multiplying it by itself 3 times (because it is put to the power of 3).
(5^4)·(5^4)·(5^4)
when you do this you can just add the exponents together
5^(4+4+4)
5^12
