Answer:
5x-y-6=
Step-by-step explanation:
(y-y1)=m(x-x1)
y-(-1) =5(x-1)
y+1=5x-5
5x-5-y-1=0
5x-y-6=0
The answer for this question is -2=5/657
Answer:
D
Step-by-step explanation:
This is an example of the Pythagorean theorem.
In triangle BEH, the sum of the squares of the sides of the two smaller sides, BE and BH is equal to the longest side squared, EH.
Answer:
The probability that computers work more than 41 minutes is 0.15866 or 15.87%.
Step-by-step explanation:
We are given that a computer tallied the time to work for 200 days and found it reasonable to the normal curve. The mean is 35 minutes, and the standard deviation with six minutes.
Let X = <u><em>the time taken by computer to work for 200 days</em></u>.
So, X ~ Normal()
The z-score probability distribution for the normal distribution is given by;
Z = ~ N(0,1)
where, = population mean time = 35 minutes
= standard deviation = 6 minutes
Now, the probability that computers work more than 41 minutes is given by = P(X > 41 minutes)
P(X > 41 minutes) = P( > ) = P(Z > 1) = 1 - P(Z 1)
= 1 - 0.84134 = <u>0.15866</u>
The above probability is calculated by looking at the value of x = 1 in the z table which has an area of 0.84134.
