Answer:
The probability that the actual event is less than 6.5 inches is 0.9999.
Step-by-step explanation:
We are given that you have determined that for this gage you have a standard error of 30%.
For a precipitation event of 5 inches, we have to find the probability that the actual event is less than 6.5 inches.
The z-score probability distribution for the normal distribution is given by;
Z = ~ N(0,1)
where, = mean precipitation event = 5 inches
standard error = = 0.30
Now, the probability that the actual event is less than 6.5 inches is given by = P(X < 6.5 inches)
P(X < 6.5 inches) = P( < ) = P(Z < 5) = 0.9999
The above probability is calculated by looking at the value of x = 5 but in the z table the last value of x is given as 4.40 so we take the area of that value only which has an area of 0.9999.

Answer:
one side of the room would be 11 feet
Step-by-step explanation:
the area is 121 square feet
take the square of it and it would be 11 feet in length and 11 feet in width
Answer:
B
Step-by-step explanation:
Given
5x + y = 14 ( subtract 5x from both sides )
y = 14 - 5x
Substituting values of x into the right side allows the corresponding value of y to be found.
x = - 1 : y = 14 - 5( - 1) = 14 + 5 = 19
x = 0 : y = 14 - 5(0) = 14 - 0 = 14
x = 1 : y = 14 - 5(1) = 14 - 5 = 9
Hence the corresponding values of x and y are
x y
- 1 19
0 14
1 9
