Answer:
The 95% of confidence intervals
(2.84 ,2.99)
Step-by-step explanation:
A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16
given small sample size n =20
sample mean x⁻ =2.92
sample standard deviation 'S' =0.16
level of significance ∝ = 0.95
The 95% of confidence intervals
the degrees of freedom γ=n-1 =20-1=19
t-table 2.093
(2.92-0.0748,2.92+0.0748)
(2.84 ,2.99)
Therefore the 95% of confidence intervals
(2.84 ,2.99)
Answer:
A, C, and E good luck
Step-by-step explanation:
-- It can't be a right triangle, because the squares of the 2 short sides
don't add up to the square of the longest side.
-- It can't be isosceles, because every isosceles triangle has 2 sides
the same length.
-- It can't be equilateral, because every equilateral triangle has all 3 sides
the same length.
-- So, out of the choices you've listed, this is a <em>scalene</em> triangle.
A scalene triangle is simply one whose sides are all different lengths.

Step-by-step explanation:
angle below x is 40 degrees because it is a corresponding angle.
x = 180 - 40 - 20 = 120 degrees
