Answer:
Population density = 47 people per square miles
Step-by-step explanation:
From the picture attached,
Coordinates of vertex B → (3.87, 2.76)
Which represents length of vertex A from origin O (AD)= 2.76 units ≈ 276 miles
Length of vertex B from origin O (CD) = 3.87 units ≈ 3.87 miles
Area of rectangle ABCD = Length × Width
= CD × AD
= 387 × 276
= 106812 square miles
Population of Colorado = 5029196 people
Population density of Colorado = 
= 
= 47.08
≈ 47 people per square miles
Answer:
2036.81
Step-by-step explanation:
1500+477.29+237.52+550=2764.81
2764.81-728=2036.81
7/10 = 0.70(7 divided by 10)
3/5 = 0.60(3 divided by 5)
9/11 = 0.81(9 divided by 11)
1/2 = 0.50 (1 divided by 2)
Answer: 9/11
The answer is: 36 π square units
Explanation:
The Area of a circle is πr ²
A = π (6) ²
6 ² =36
Therefore the answer is 36 π
Answer:
0.8780
Step-by-step explanation:
“What is the value of the test statistic? Round your answer to two decimal places.”
We must find a value of z, such that the area under the Normal curve with mean
= (0.92 - 0.85) = 0.07
and standard deviation
s = 0.023
between (
, 0.07 + z*0.023] is 95% = 0.95
We use then a spreadsheet to work out that value z*0.023 = 0.108 (See picture), and
z = 0.108/0.023 = 0.8780
