Answer:
y+10 = 2(x+1)
Step-by-step explanation:
We have two points so we can find the slope
(−1,−10) and (5,2)
m = (y2-y1)/(x2-x1)
= (2- -10)/(5 - -1)
= (2+10)/(5+1)
= 12/6
=2
The point slope form is
y-y1 = m(x-x1)
y - -10 = 2(x--1)
y+10 = 2(x+1)
If we use the other point
y -2 = 2(x-5)
Answer:
The probability that the next failure will not occur before 30 months have elapsed is 0.0454
Step-by-step explanation:
Using Poisson distribution where
t= number of units of time
x= number of occurrences in t units of time
λ= average number of occurrences per unit of time
P(x;λt) = e raise to power (-λt) multiplied by λtˣ divided by x!
here λt = 25
x= 30
P(x= 30) = 25³⁰e⁻²⁵/ 30!
P (x= 30) = 8.67 E41 * 1.3887 E-11/30! (where E= exponent)
P (x=30) = 1.204 E31/30!
Solving it with a statistical calculator would give
P (x=30) = 0.0454
The probability that the next failure will not occur before 30 months have elapsed is 0.0454
Answer: 
Step-by-step explanation:
The missing figure is attached.
The volume of grain that could completely fill this silo is the sum of the volume of the cylinder and the volume of the hemisphere.
By definition, the volume of a cylinder can be calculated with this formula:

Where "r" is the radius and "h" is the height.
In this case you know that:

And the volume of a hemisphere can be found using the following formula:

Where "r" is the radius.
In this case:

Therefore, the volume of grain that could completely fill this silo, rounded to the nearest whole number, is:

Answer:
3. Adrian kept an eye on the basketball game score by looking online every 10 minutes. Over the course of
2 hours, 4 times Adrian’s favorite team was ahead by 3 points, and 4 times Adrian’s favorite team was behind
by 4 points. All other times, the two teams were tied.
(a) What is the average score of Adrian’s favorite team relative to its opponent using the observations
Adrian made during the game? Show your work neatly.
(b) Explain what this value means about Adrian’s favorite team’s performance
