Same and same. They're congruent which means they have the same size and the same shape.
Answer:
Step-by-step explanation:
Given that an exit poll of 1000 randomly selected voters found that 515 favored measure A.
Sample proportion p =
Margin of error 99% = 2.58*SE
=
99% confidence interval =

(Right tailed test)
STd error =
Test statistic Z = p diff/std error =
p value = 0.1714
Answer:
The given equation 3x^2-4x+21 has no factors.
Step-by-step explanation:
We need to factorize this equation.
For factorization we split the middle term such that their sum is equal to middle term and product is equal to product of first and last term of the given expression.
in Our case : 63x^2
We need to find two factors of 63x^2 whose sum is equal to -4x
Factors of 63= 1,3,7,9,21,63
1* 63
3*21
7*9
None of the above factors sum is equal to -4.
So, the given equation 3x^2-4x+21 has no factors.
Answer:10
Step-by-step explanation:because 10 has no solution
Answer:
Step-by-step explanation:
It doesn't look right to me, but you may not have the choices I would want to use. I think it should go
1/2
cos^2
sqrt(x)
+ 2)
The square root covers just the x, and nothing more.
