The question comprises two numbers and a letter - possibly a variable - followed by a question mark. There is no indication as to how the numbers relate, if at all, with the letter. Nor is it possible to tell what the question is about.

What percent of people have an IQ over 115?
About 15.87% of people have an IQ over 115.z=(115-100)/15=1Z-score of 1 on a normal distribution means 84.13% have an IQ below 115 and 15.87% have an IQ above 115.IQ Graphhttp://8.17.172.75/uiq/images/bellcurve.gif
Euler's identity for sine?
sin(z)= (e^(i*z)-e^(-i*z))/(2*i) where i=(-1)^(1/2)
What is z sqared minus 5z plus 4 equal zero?
Z2 - 5Z + 4 = 0 (Z- 1)(Z - 4) so, Z = 1 ---------- and Z = 4 -----------
If y times x-1 equals z then x equals?
y * (x-1) = z Express as x,divide both sides by y(x - 1) = z/yadd 1 on both sidesx = z/y + 1
How do you solve 1 divided by x minus 1 divided by y equals 1 divided by z solve for z?
(1/x) - (1/y) = (1/z) Get the left-hand side over a common denominator:- (y-x)/xy = 1/z Take the reciprocal of both sides:- z = xy / (y-x)

Can you understand my proof about Fermat?
Pierre De Fermat 's last Theorem. The conditions: x,y,z,n are the integers and >0. n>2. Proof: z^n=/x^n+y^n.

What is the relative frequency of score less than 120 using the 68-95-99.7 rule if a set of test scores is normally distributed with a mean of 100 and a standard deviation of 20?
120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84
What are the properties of z in a normal distribution?
Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.
If x exceeds y by 1 and y exceeds z by 3 how are x and z related?
x + 1 = y y + 3 = z z = y + 3 = (x + 1) + 3 = x + 4 Or: x = y - 1 = (z - 3) - 1 = z - 4 Which results in the same: x exceeds z by 4.
