Answer:
Step-by-step explanation:
We start by adding 
to both sides, giving 
, which after simplifying gives 
.
We then add 
to both sides, giving 
, which after simplifying gives 
.
We can then divide both sides by 
, giving 
, which after simplifying gives 
, or . So, x is 5.
The figure below shows the standard normal distribution or "bell-shaped" curve, plotted against the z-score.
The z-score is defined as
z = (x - μ)/σ
where
x = nrandom variable
μ = mean
σ = standard deviation.
As z-values decrease, areas to the left of z decrease as shown by the shaded area.
Answer:
Areas to the left of z decrease.
You can answer it in fraction or decimal.
Fraction: In fraction, write 9 above 917 like this: 9/917. That is the answer in fraction.
Decimal: In decimal, do the long-division algorithm. You should get 0.009815.
96/10 = 9.6
Therefore 96 - 9.6 = 86.4
