Answer:
Not similar
Step-by-step explanation:
Two polygons are similar if their corresponding side lengths are proportional to each other. In other words, the ratio of their corresponding side lengths should be the same.
Let's find the ratio of the corresponding side lengths:
3/5 = 3/5
4/12 = 1/3
5/13 = 5/13
3/5 ≠ 4/12 ≠ 5/13
The ratio of their corresponding side lengths are not equal, therefore, the two polygons are not similar to each other.
Answer:
second choice
Step-by-step explanation:
First, do the composition of the functions.
Now we find (fog)(9).
(fog)(9) evaluates to a real number, so 9 is in the domain of the composition of functions f and g.
Answer: second choice
Answer:
Option B
Step-by-step explanation:
Since the company that Carrie out the survey after the students also arrived at the same conclusion as the student which is: no evidence that preference for brand A is not 0.5. We can say that she did not make any error which could be a type 1 or 2 error and found that the actual value was 0.5 which is the null hypothesis
Null hypothesis: u = 0.5 for brand A
and thus fails to reject the null hypothesis.
Answer:
x=3; y= -10
I will prefer addition of equation instead of substitution, but you asked how to substitute
Step-by-step explanation:
-x+y=-13
y=x-13
3x-(x-13)=19
3x-x+13=19
2x=6, x=3
-3+y=-13, y=-13+3, y=-10
Answer:
960m
Step-by-step explanation:
a^2 + b^2 = c^2
6m + 10m = 16m
6m * 10m * 16m = 960m
Yeah im probably wrong wait for someone else to answer
