Answer: 69
Step-by-step explanation:
The two angles are a linear pair, which means that they lie on the same line. Therefore, you just have to substract angle 1 with 180.
180-111=69
Answer: b. H0: μ ≥ 5; Ha: μ < 5
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
The mean is 5 years and they claim it will perform for more than 5 years.
Therefore, for the case above;
H0: μ ≥ 5; Ha: μ < 5
Note: a null hypothesis must always include an equal to sign.
