Step-by-step explanation:
so the smaller one is two right? we can divide 96 by 2 to get 48 for each one
to find the bigger we simply multiply 48 by 5 to get 240
Answer: Our required probability would be 0.9641.
Step-by-step explanation:
Since we have given that
Number of hours he works a day = 8
So, Number of minutes he worked in a day = 
Number of calls = 220
So, Average 
Standard deviation 
Mean = μ = 2.0 minutes
Standard deviation = σ = 1.5 minutes
Using the normal distribution, we get that

So, the probability that Albert will meet or exceed his quota would be

Hence, our required probability would be 0.9641.
Answer:
y=124°
x=67°
Step-by-step explanation:
For the triangle on the right
180-74-50=56°
then y= 180-56=124°
For the triangle on the middle (that small triangle)
180-85(Head opposite angles)-50=45°
So
x=180-45-68=67°
Answer: The average velocity of the object over the time interval [3,6] is 20.
Step-by-step explanation:
Since we have given that
s(3) = 156
s(6) = 216
We need to find the average velocity over the time interval [3,6].
So, average velocity becomes

Hence, the average velocity of the object over the time interval [3,6] is 20.
