Add up the lengths of all the sides or one side length multiplied by 4!
Answer:
(A) We failed to reject the null hypothesis
Step-by-step explanation:
Given that a high school teacher hypothesized that in her class, boys were taller than girls. If the probability value of her null hypothesis is 0.34, it means:
Here p value is 0.34
This is greater than 0.05 or 0.1 i.e. both for 5% significance and 10% significance.
Whenever p > alpha, we fail to reject null hypothesis
A) We failed to reject the null hypothesis
This would be the correct option
i.e. final conclusion is that there is no significant difference between mean height of girls and mean height of boys at 5% or 10% significance level.
Answer:
<h2>3. If a ≥ b, then a + c ≥ b + c
</h2><h2>4. If c > d, then a– c < a – d</h2>
Step-by-step explanation:
The inequalities 3 and 4 are the right ones, because they are actually properties of inequalities.
The other choices aren't correct. For example, the first choice: a – b < a + b, it's not true, because you must apply the same change at each side of the inequality, otherwise you'll ruin the expression.
Choices 2 and 5 are also false.
Therefore, the right answers are 3 and 4.
