Hello, there!
5/4 = 1.25
So, we know that the answer is not A or B.
1.25 = 125%
Now, we know that the answer is not D ether.
So, the answer must be C.
I hope I helped!
Let me know if you need anything else!

Answer:
Approximately 120.31 people per square mile
Step-by-step explanation:
1) The population density can be found by dividing the whole population over the area.
2) Since the NH map is modeled like this triangle, let's firstly calculate its area.
3) Based upon the original picture, and tracing it on we can easily see that the y coordinate is little bit over 200, precisely 220. Each mark on the original y-axis count as 20 miles. That'll give us the height.
The base of the triangle is 100 miles for F(100,0). Plugging that information on the formula:
4) The Population density:
Answer:
Shape Number of Lines of Reflection Description
equilateral triangle 3 3 perpendicular bisectors of the sides
regular heptagon 7 7 perpendicular bisectors of the sides
regular octagon 8 4 perpendicular bisectors and 4 lines joining pairs of opposite vertices
Step-by-step explanation:
Answer:
-1.00
Step-by-step explanation:
Given that a publisher reports that 45% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.
Sample size n =190
Sample proportion p = 0.41
(Two tailed test )
Assuming H0 to be true
std error =
p difference = -0.04
Test statistic = p differencce/std error
= -1
Hence test statistic is -1.00
