Answer:
The Slope= -13/3
y-intercept= (0,5/3)
Step-by-step explanation:
m= change in y/change in x
m= y2-y1/x2-x1
m=6-(-7)/ -1-(2)
m=-13/3
Answer:
It is 3*10^6 times bigger
Step-by-step explanation:
<u>9*10^-4</u>
3*10^-10
=9/3*10^(-4-(-10))
=3*10^6
Using the given discrete distribution, it is found that the expected value is of $863.93.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution of costs is given by:
Hence, the expected value is given by:
E(X) = 0.87 x 986 + 0.13 x 47 = $863.93.

Step-by-step explanation:
47.5 * 3.3 /1.74 = 90.09
Answer:
Probability is 0.3506
Step-by-step explanation:
We are given
mean is 8mm
so, 
standard deviation is 2.2 mm
so, 
x-varies from 7mm to 9mm
At x=7:
we can use formula
we can plug values
At x=9:
we can use formula
we can plug values
So, z is between -0.45455 and 0.45455
now, we can use normal distribution table
and we get
Probability is 0.3506
