Answer:
The two distributions are each nearly symmetric.
Step-by-step explanation:
Symmetric distributions are those in which the data occurs in regular frequencies.
If we calculate the difference between the two standard deviations we find that it is only 0.022 which may be due to the physical or chemical properties of water or salt. So it lies within the same range and is almost symmetrical.
We cannot say that the distributions do not overlap on the same range of temperatures because they lie within the same range.
These two options are also incorrect as they are totally opposite of each other. Suppose the distribution of salt water boiling temperatures is left-skewed then the distribution of tap water boiling temperatures cannot be right-skewed as they have the same range and vice versa.
Answer:
2x^3-8x^2+8x+12
Step-by-step explanation:
split them up
use distributive property
2x-6(x-2)
2x^2-4x-6x+12(x+1)
use distributive property again
2x^3+2x^2-4x^2-4x-6x^2-6x+12x+12
simplify
2x^3-8x^2+8x+12
I forgot if you can divide it by 2 or not to simplify it even more. If you can, divide it by 2. I forgot the rules
If you divide it by 2, then the answer is
x^3-4x^2+4x+6
A tree diagram can be drawn for a clearer understanding. The branches of the tails can be ignored since we are not concerned about that. To find the probability along the branches, we just have to multiply the probabilities of each branch, giving you an answer of 1/128
Answer:
22,5 km
Step-by-step explanation:
9 gallons of water
Divide the gallons by the number of plants.
6 ÷ 20 = 0.3
Multiply that by the number of plants you want.
0.3 x 30 = 9
