a) answer
to prove the given triangles ABC and ADC are congruent we should use S.S.S axiom because all the sides of given triangles are equal.
b) answer
we cant use S.A.S axiom where it look like that given triangles BAC and DAC angle are equal because same length
of sides cant decides the angle.
Answer:
Correct option is (A). <em>H₀</em>: = 0.5
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for a population parameter can be used to determine whether to reject a null hypothesis or not.
The decision rule is:
If the (1 - <em>α</em>)% confidence interval for a population parameter consists of the null value of the parameter then the null hypothesis will be accepted or else it will be rejected.
A hypothesis test is performed to determine the difference between the ideal and actual heights of college males.
The 95% confidence interval for the mean difference, is:
CI = (0.8, 2.2)
The four null hypothesis provided are:
- H₀: = 0.5
- H₀: = 1.0
- H₀: = 1.5
- H₀: = 2.0
The 95% confidence interval for the mean difference consists of the value, 1.0, 1.5 and 2.0.
But it does not consist the value 0.5.
So, the null hypothesis that can be rejected is:
<em>H₀</em>: = 0.5
Thus, the correct option is (A).
20.5x2=41
8.2x5=41
Hope this helpful, but since 41 is a prime number, it's only whole number factors are 1 and 41.
