Step-by-step explanation:
If four players are left, then there are 117 – 4 = 113 players who have been eliminated.
Given:
volume of the block = 576 cubic inches
Square pyramid = base area : 3 square inches ; height = 4 inches
Volume of square pyramid = a² * h/3
V = 3 square inches * 4inches/3
V = 4 cubic inches
volume of block / volume of square pyramid
576 cubic inches / 4 cubic inches = 144
She can make 144 square pyramids.
Answer:
The major condition that needs to be satisfied before a t-test is performed that the question satisfies easily is the use of random sampling to obtain sample data.
Step-by-step explanation:
The major conditions necessary to conduct a t-test about a mean include;
- The sample extracted from the population must be extracted using random sampling. That is, the sample must be a random sample of the population.
- The sampling distribution must be normal or approximately normal. This is achievable when the population distribution is normal or approximately normal.
- Each observation in the sample data must have an independent outcome. That is, the outcome/result of each sub-data mustn't depend on one another.
Of the three conditions that need to be satisfied before the conduction of a t-test, the first condition about using a random sampling technique is evidently satisfied.
It is stated in the question that 'A private investigator hired by a competitor takes a random sample of 47 games and tries to determine if there are more than 7 glitches per game'.
