The test hypothesis is :
: the basis for the judgement does not affects the quality of the judgment.
: the basis for the judgement affects the quality of the judgement.
Given a = 0.05, since the p-value is less than 0.05, so we reject .
Therefore, the basis for the judgement affects the quality of the judgement.
Yes, because all together the books and pens add up to $8.06
The volume of the pyramid is calculated by multiplying the area of the base by the height of the figure. For this item, for the figures to have the same volume,
V = B1H1 = B2H2
Then, we substitute the given values, and since we are not given the shape of the base and the volume of the entire figure, we can just solve it through the way below.
(20 in)(21 in) = (x in)(84 in)
The value of x in the problem is 5 inches.
Answer:
On a fair die, half the numbers are even and half the numbers are odd. So, the probability for a single roll of getting an even number or an odd number is 12. So, the odds are 7:1 against the desired outcome
