Answer:
15
Step-by-step explanation:
35-20= 15
Answer:
y ≤ q 0 or y ≥ 16.
Step-by-step explanation:
Rearrange unknown terms to the left side of the equation: |y - 8| ≥ q 19
for the table its 30 * the hours +20 for example 30(1)+20=50 or 30(4)+20=140. the total cost is 30 times the hours plus 20.
Answer: Time taken =1.25 x 10^1 hours 0r 4.5 x 10^4s
Step-by-step explanation:
Step 1
how long will it take the rocket to make the trip from Earth to the satellite = Time taken for the rocket to make the trip from Earth to the satellite
Speed = Distance / Time ,
Time = Distance / speed
Step 2-- solving
Time = Distance / speed
Time=2.5×10^5 miles/2.0×10^4 miles per hour
=12.5 hours = 1.25 x 10^1 hours
or 1.25 x 10^1 hours x 3600 = 45,000 seconds = 4.5 x 10^4s
Answer:
![P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)](https://tex.z-dn.net/?f=%20P%28X%20%5Cgeq%208%29%3D%20P%28X%3D8%29%20%2BP%28X%3D9%29%20%2BP%28X%3D10%29)
And we can find the individual probabilities like this:
And adding we got:
![P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)= 0.176+0.072+0.013=0.262](https://tex.z-dn.net/?f=%20P%28X%20%5Cgeq%208%29%3D%20P%28X%3D8%29%20%2BP%28X%3D9%29%20%2BP%28X%3D10%29%3D%200.176%2B0.072%2B0.013%3D0.262)
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, 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:
Solution to the problem
For this case we want to find this probability:
![P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)](https://tex.z-dn.net/?f=%20P%28X%20%5Cgeq%208%29%3D%20P%28X%3D8%29%20%2BP%28X%3D9%29%20%2BP%28X%3D10%29)
And we can find the individual probabilities like this:
And adding we got:
![P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)= 0.176+0.072+0.013=0.262](https://tex.z-dn.net/?f=%20P%28X%20%5Cgeq%208%29%3D%20P%28X%3D8%29%20%2BP%28X%3D9%29%20%2BP%28X%3D10%29%3D%200.176%2B0.072%2B0.013%3D0.262)
