Answer:
Yes; they are congruent
SSS
Step-by-step explanation:
Here, we want to check if the given triangles are congruent
From what we have, we can see that all three sides are marked for both triangles
So the sides of the triangles are income
So therefore, the triangles are congruent by SSS
Answer:
since it is Right angled isosceles triangle it's base side are equal
by using Pythagoras law
x²+x²=1²
2x²=1
x=√{1/2}or 0.707 or 0.71
Answer:
And rounded up we have that n=656
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 80% of confidence, our significance level would be given by
and
. And the critical value would be given by:
Solution to the problem
The margin of error for the proportion interval is given by this formula:
(a)
Since we don't have prior info for the proportion of interest we can use
as estimator. And on this case we have that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=656
Answer:
here is your answer....
Step-by-step explanation:
lets take x as 8
t(8)=3*8
t(8)=24
Therefore:
we get t(x)=24 from equation t(x)=3x
