She should not spin the spinner any more times, the relative probability is already more than the theoretical probability.
If there is only 1 purple section out of 8, that gives purple a 12.5% chance of being spun.
However, Lara got purple 30 out of 120 times. That is 25%. She is already over.
How many of the sections were purple?
You got it right you did a fantastic job
Answer:
I=\frac{t^2}{2}
Step-by-step explanation:
From exercise we have that x=t, t>0. Because A(t) be the area of the region in the first quadrant, we get that x started at 0. The limits for y are the following e-x and e. We get the integral :
I=\int\limits^0_t \int\limits^{e}_{e-x} 1 dy dx
I=\int\limits^0_t [y]_{e-x}^{e} dx
I=\int\limits^0_t (e-e+x) dx
I=\int\limits^0_t {x} \, dx
I=[\frac{x^2}{2} ]_{0}^{t}
I=\frac{t^2}{2}
