Rise/Run, so it rises 20, it runs 3, so it is 20/3, or 6 2/3.
Answer:
x=10.7, y=11300
Step-by-step explanation:
x%of 31 = 3.317
x/100×31=3.317
31x/100=3.317
31x= 3.317×100
x= 3.317 ×100/31
x =10.7
4407= 39% of y
4407= 39/100 × y
4407 =39y/100
4407×100=39y
4407 × 100/39=y
11300=y
The circle area formula is A=pi r^2. I am assuming those numbers represent diameter, and diameter is radius x 2. 6/2=3, and pi 3^2= 28.27433388. Divide this by 2 and the area of your half circle is 14.13716694. On the other half circle, 5/2= 2.5. pi times 2.5^2 is 19.63495408, divided by two is 9.817477042. Hope it helps!
A normally distributed result means that when the data is
plotted on a graph, we can actually see a bell shaped curve. That highest
frequency or peak is centered on the average value. Because it is shaped like
this, we can say that:
most scores are around the average with some scores being
lower or higher
