Robert spun the fair spinner shown below 1,060 times, About how many times would Robert expect to spin a 1, 3, or 8?

About 400 times

Step-by-step explanation:

Given

See attachment for spinner

Required

Determine the number of times an outcome of 1, 3 or 8 is expected

First, calculate the theoretical probability of 1, 3, or 8

This is calculated as:

The spinner is divided into 8 equal segments and each outcome appears once.

So, we have:

Take LCM and add

So, the expected number of times (E) is:

Approximate

This means about 400 times

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
