Answer:
option (3) is correct.

Step-by-step explanation:
Given 
We have to solve for e.
Consider the given statement,

Cross multiply, we get,

Taking square root both sides , we get,

We know square root of 9 is 3.

Thus, option (3) is correct.

Answer:
The probability of not spinning a 5, flipping heads, then spinning a 1 is 0.08
Step-by-step explanation:
I may assume the spin contains 5 numbers ( plz change and recalculate if the no. of numbers is different)
P(not spinning a 5) = 4/5
P(flipping head) = 1/2
P(spinning 1) = 1/5
P(not spinning a 5, flipping heads, then spinning a 1)= 4/5 * 1/2 * 1/5 = 0.08 = 0.1
The minimum speed will be calculated as follows:
Time taken from Toledo to Elkhart=(8.15-5.45)=2 1/2 hours
Distance=136 miles
thus the speed between Toledo and Elkhart= 136 miles/2.5=54.4 mph
Distance between Toledo and Chicago is 244 miles
Distance between Elkhart and Chicago=244-136=108 miles
time taken to travel between Elkhart and Chicago assuming that I left Elkhart at exactly 8:15 and reach at 10.30:
=10:30-8:15=2.25 hours
thus the speed will be:
speed=(108)/(2.25)=48 mph
Thus for us to get to Chicago by 10:30 a.m we should drive at 48 mph
