Answer:
Figure C
Step-by-step explanation:
Figure A represents a ray because it has arrow only on one end.
Figure B is a line segment because it stops on both ends.
Figure C is a line because it has arrow on both ends.
Figure D is an angle, because it is 2 rays joined at a vertex.
Answer:
13 1/3
Step-by-step explanation:
8 Divided by 3/5 = 8 times 5/3.
8x5=40
3x1=3
40/3 = 13 1/3
Similar rectangles have or form similar ratios. Hence to solve this, you have to get the ratio of the measurements:
Let N be the length of the similar rectangle
5/7 = 15/N
5(N) = 7(15) -> cross multiply
5N = 105
5N/5 = 105/5 -> divide both sides of the equation by 5
N = 21
Therefore, 21 meters in the length of the similar rectangle
To check -
5/7 = 15/21 (cross multiply)
105 = 105
Answer:
The area under the function
.
Step-by-step explanation:
We want to find the Riemann Sum for
with 4 sub-intervals, using right endpoints.
A Riemann Sum is a method for approximating the total area underneath a curve on a graph, otherwise known as an integral.
The Right Riemann Sum is given by:

where 
From the information given we know that a = 1, b = 3, n = 4.
Therefore, 
We need to divide the interval [1, 3] into 4 sub-intervals of length
:
![\left[1, \frac{3}{2}\right], \left[\frac{3}{2}, 2\right], \left[2, \frac{5}{2}\right], \left[\frac{5}{2}, 3\right]](https://tex.z-dn.net/?f=%5Cleft%5B1%2C%20%5Cfrac%7B3%7D%7B2%7D%5Cright%5D%2C%20%5Cleft%5B%5Cfrac%7B3%7D%7B2%7D%2C%202%5Cright%5D%2C%20%5Cleft%5B2%2C%20%5Cfrac%7B5%7D%7B2%7D%5Cright%5D%2C%20%5Cleft%5B%5Cfrac%7B5%7D%7B2%7D%2C%203%5Cright%5D)
Now, we just evaluate the function at the right endpoints:




Next, we use the Right Riemann Sum formula

Answer:
There are many conclusions we can come to for this!
70% of the flips were heads, and 30% are tails
28/40 was heads, and 12/40 were tails
There were more heads than tails
There were 14 more heads than tails
