Car A: 18/20(60)=54 mph
Car B: 13/12(60) = 65 mph
So car b travels 11 more miles than car a in one hour
Answer:

And using the probability mass function we can find the individual probabilities:


And replacing we got:
![P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%202%29%3D1%20-%5B0.2044%20%2B0.3590%5D%3D%200.4366)
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Step-by-step explanation:
Let X the random variable of interest "number of seniors who disapprove of daily smoking ", on this case we now that:

The probability mass function for the Binomial distribution is given as:

Where (nCx) means combinatory and it's given by this formula:

And we want to find this probability:

And using the probability mass function we can find the individual probabilities:


And replacing we got:
![P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%202%29%3D1%20-%5B0.2044%20%2B0.3590%5D%3D%200.4366)
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Answer:
x=-1 and x=3
Step-by-step explanation:
The zeroes of a function are its x-intercepts when the function passes through the x-axis. In this case, the parabola passes through (0,-1) and (0,3) which means the x-intercepts are x=-1 and x=3, which are also the zeroes.
Answer:
Step-by-step explanation:
so he gets a 12% commission on his sales. He sold a slide that costs 270.
so he would get 12% of 270
turn ur percent to a decimal..." of " means multiply
0.12 * 270 = $ 32.40 <===
