Using the data you gave I made an equation
(x+3+11+9+7+3)/6 = x
(The formula for finding the mean is the sum of observations divided by total no of observations)
And I equated it (refer the picture)
x = 33/5 = 6.6
Hope this helped you!
Answer:
0.6065
Step-by-step explanation:
Probability mass function of probability distribution : 
a mean of 0.05 flaw per square foot
Each car contains 10 sq.feet of the plastic roll
Mean = 0.05
Mean = 
We are supposed to find What is the probability that there are no flaws in a given car’s interior i.e,P(X=0)
Substitute the value in the formula
Hence the probability that there are no flaws in a given car’s interior is 0.6065
-- Find any point where y=4
-- Find another point where y=4
-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.
The equation for every straight line is [ y = mx+b ].
This is the line where (m = 0) and (b = 4).
Answer:
A = 400 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the vertical height ) , then
A = × 20 × 40 = 10 × 40 = 400 ft²
