A thumbtack that is tossed can land point up or point down. The probability of a tack landing point up is 0.2. A simulation was
conducted in which a trial consisted of tossing 5 thumbtacks and recording the number of thumbtacks that land point up. Many trials of the simulation were conducted and the results are shown in the histogram.
Based on the results of the simulation, which of the following is closest to the probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed?
A 0.09
B 0.19
C 0.28
D 0.72
E 0.91

Answer with explanation:
For any object having the velocity vector as
the magnitude of velocity is given by
For car 1 the velocity vector is
Therefore
Similarly for car 2 we have
Therefore
Comparing both the values we find that car 1 has the greater speed.
An inequality that represents Denise's goal in terms of the number of hours spent running 'h'
Given :
Denise wants to burn at least 5000 calories a week through running.
she can burn 550 calories per hour
Let 'h' be the number of hours spent
In 1 hour she can burn 550 calories
In 'h' hours she can burn 550h calories
Given that she want to burn atleast 5000 calories in a week
Burn atleast 5000 calories means <=5000 calories
So , the inequality that represents Denise's goal is
calories burn in h hours <= 5000 calories
