It landed on red 102 times out of 300 spins
that is 102/300 which can reduce to 17/50 as a fraction
17/50 = 0.34 as a decimal
Cos38 = 7,8/x
X= 7,8/cos38
= 9,90
Answer: x=42
Step-by-step explanation: In the picture
Slope intercept form is y=mx+b
m=slope
b=y-intercept
the slope is the rate of change of the graph, basically rise/run (change in y divided by change in x)
the y intercept is where the graph intercepts the y axis
we usually use this form because we can find the slope and find where it hits the y axis.
there are other forms that may be helpful later on, but this one is usually the easiest form to find from a graph
