Answer:
D. 22%
Step-by-step explanation:
89 of the 374 cars in the table are red. Without knowing more about the sampling process used to obtain the table data, the best we can do is assume that proportion holds for the whole country.
... 89/374 ≈ 22% . . . . matches selection D
_____
Using these numbers gives higher weight to larger samples, which does not seem unreasonable—unless the larger sample favors red cars for some reason.
So for this problem you need to find the length of a side of the square. To do this you can use Pythagorean theorem to find the length of the right triangle with the side of the square as it’s hypotenuse.
The Pythagorean theorem is:
a^2 + b^2 = c^2
a = 1 and b = 3
1^2 + 3^2 = c^2
10 = c^2
square root of 10 = c
Now that we know the length of the side, we can find the area of the square. Area of a square = side^2, so:
Area = (square root of 10)^2 = 10
The area of the square is 10!

Step-by-step explanation:
Answer:
1=101 4=79 2=79
Step-by-step explanation:
Angle 3 is given as 101. The angle across from it has to be the same angle measure so angle 1 is 101. Because the angle 4 added to 3 is a straight line or 180 degrees (half a circle) than you just have to subtract angle 3 from 180 to get angle 4 which is 79. Angle 4 and angle 2 have to be the same so angle 2 is 79. I hope this helps
Answer:
750
Step-by-step explanation:
150 is bigger than 100 so we know the answer has to be bigger than 500. 150/100*500=150*5=750
