Answer:
2.5 km
Step-by-step explanation:
First, find the area of the region:
- A circular region has a population of about 15,500 people;
- A population density of about 775 people per square kilometer.
So, there are
square kilometers.
Now, let x kilometers be the radius of the circular region, then

To the nearest tenth this is 2.5 km.

Answer:
1- 10% of -80 is -8.
2- 28 is 4% of 700.
3- 25% of a number is equal to 1/4 or 0.25 of it.
4- 13% of a number is equal to 0.13 of it.
5- 15 is 12.5% of 120.
Step-by-step explanation:
1. 10% of ________- 8
2.28 is 4% of _________
3.25% of ________
4.13% of______
5.15 is 12.5% of _____
To determine the missing numbers in the statements, the following calculations must be performed:
1-
10 = -8
100 = X
100 x -8 / 10 = X
-800 / 10 = X
-80 = X
Therefore, 10% of -80 is -8.
two-
4 = 28
100 = X
100 x 28/4 = X
2800/4 = X
700 = X
Therefore, 28 is 4% of 700.
3-
25% of a number is equal to 1/4 or 0.25 of it.
4-
13% of a number is equal to 0.13 of it.
5-
12.5 = 15
100 = X
100 x 15 / 12.5 = X
1500 / 12.5 = X
120 = X
Therefore, 15 is 12.5% of 120.
No because the same number can’t have 2 different signs, and btw some answers that you have are wrong (2,5)
Answer:
Option D. Strong positive correlation
Step-by-step explanation:
Like the r-value of 0.987 is positive (0.987>0) and close to 1, the correlation of the graph is a strong positive correlation
