Answer:
8x+4x+9x
Step-by-step explanation:
Finding the perimeter is just adding the sides
to find the area you multiply instead
Answer: The level of significance, , is the probability of committing a Type I error, rejecting the null hypothesis when it is, in fact, true.
Step-by-step explanation:
The significance level, which is commonly designated as alpha (α) is defined the probability of rejecting the null hypothesis when it is in fact, true.
To determine statistical significance, a researcher is expected to calculate a p-value. The researcher can reject the null hypothesis if the p -value is less than α as established by the researcher.
Uhhh is this a real question because if it is I feel bad for the person who has to solve it lol
To solve for this, we need to get n by itself on one side, then solve from there.
Currently, our equation is 8n - 8 = 6n + 6.
Get n on one side, subtract 6n from both sides.
2n - 8 = 6
Add 8 to both sides.
2n = 14
Divide by 2 to get n.
n = 7.
I hope this helps!
By the markings on the angles,
A ≅ D
B ≅ F
C ≅ E
So ΔABC ~ ΔDFE . . . . . . . . matches the 3rd selection
