Answer:
The area is 8000 square feet.
Step-by-step explanation:
Since one inch in the drawing is equal to 20 feet, multiply 4 by 20 to get the length in feet. So the length equals 80 feet. Then multiply 5 by 20 to get the width. So the width equals 100. Finally plug the width and the length into the formula for Area. A= length X width; A= 80 X 100; A= 8000

Answer:
no
Step-by-step explanation:
Given:
μ = $3.26 million, averaged salary
σ = $1.2 million, standard deviation
n = 100, sample size.
Let x = random test value
We want to determine P(x>4).
Calculate z-score.
z = (x - μ)/ (σ/√n) = (4 - 3.26)/(1.2/10) = 6.1667
From standard tables,
P(z<6.1667) = 1
The area under the distribution curve = 1.
Therefore
P(z>6.1667) = 1 - P(z<=6.1667) = 1 - 1 = 0
Answer: The probability is 0.
