Answer:
6600 yd²
Step-by-step explanation:
The area of the scale drawing is ...
(5.5 in)(3 in) = 16.5 in²
Each square inch represents an area of the field that is ...
(20 yd)×(20 yd) = 400 yd² . . . . per square inch of drawing
Then the scale drawing represents a field with an area of ...
(16.5 in²)×(400 yd²/in²) = 6600 yd²
Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
