Answer:
yes the two triangles are congruent by the SSS theorum.
Step-by-step explanation:
it is given that two of the sides are congruent. they also share a side making that side also congruent. so, all three sides are equal, making the two triangles congruent by SSS/side-side-side theorum.
Answer: F
Critical regions get smaller as α-values get smaller.
Explanation:
The figure below shows the critical regions (shaded) for a 2-tailed test at the 95% confidence level.
Because the total area under the curve is 1, the α-value is 1 - 0.95 = 0.05.
It is split up into 0.025 for a two-tailed test. It remains at 0.05 for a one-tailed test.
The critical z-score at 95% confidence level is z* = 1.96.
When the α-value decreases:
(a) the z* value increases,
(b) the confidence level increases,
(c) the critical region decreases.
Answer:
117.53 feet^2
Step-by-step explanation:
So to start off we need to find the area of the pentagon.
The formula for the area of a pentagon is weird so I’m not going to write it but you can search it up.
So the area would be 27.53 inches^2.
Now for the triangles.
There is 5 triangles in total with a base of 4 and a height of 9.
So the area of one is base*height divided by two.
So it would be 18.
Now we can just multiply 18 by 5 which is 90 feet^2.
So when we add up 90 and 27.53 we get 117.53 feet^2.
Answer:
if you take 180-124 you would get 56 then you would take 56 divided by 2x which would give you 28
