<span>In math notation, we've done this: z = (X - μ) / σ = (940 - 850) / 100 = 0.90
where z is the z-score
X is Vivian's score (940)
µ is the mean (850)
σ is the standard deviation (100)
As you may know, in a normal distribution it's expected that about 68% of all observations will fall within 1 standard deviation of the mean, 95% will fall within 2 standard deviations, and 99% will fall within 3 standard deviations.
940 lie before the first standard deviation, in which 16.5% is above it
since 940 is 0.9 from the mean and 0.1 from the first standard deviation
so above it is 17.5 % = 0.175 or about 0.18 </span>
logarithmic form and although the equations will look different, the equations ... To discuss what a logarithm is, we need to take a look at an exponential function. ... If b > 1, then the graph created will be exponential growth. ... To learn how to change an equation from exponential form to logarithmic form, let's look at a specific.
Answer:
If 30% of 599.99 is 197.99 and 30% of 899.99 is 269.99 then you subtract 269.99-197.99= $72

Answer:
The answer is the Kiki word problem
Step-by-step explanation:
![\sf\dfrac{3}{11}-(-\dfrac{6}{11})](https://tex.z-dn.net/?f=%5Csf%5Cdfrac%7B3%7D%7B11%7D-%28-%5Cdfrac%7B6%7D%7B11%7D%29)
Two negatives equals a positive:
