Answer:
B.
Step-by-step explanation:
The sample size taken for the school is too small.
5 people not being vegetarian does not mean NO OTHER students are vegetarian also. Thus, an assumption based on this probability of 5 people would not be correct unless fully supported. This makes option A wrong.
Answer B is correct because with small numbers, probability varies a lot and may change drastically with the addition of data.
For example: the 6th person we sample says he/she is a vegetarian.
This would change the probability drastically to 1/6 = 0.1667
Because this is a drastic change, and fluctuation is clear, answer B is correct.
C is wrong because probability is not subjective.
The other side is 4 feet, and the perimeter it 12 feet
Answer: The 80ml is the best deal
Step-by-step explanation:
Bc the half price of 45 is 22.5 so 45 + 22.5 equals $67.50 and the 80ml would equal 55.
Therefore the 80ml one is cheaper than the 50ml
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
Answer:
88.67 degrees
Step-by-step explanation:
To find the value of A, undo the tangent operation using the inverse. Use the inverse to find A.
A = 88.67
