Total drops = 4 + 10 = 14
Total cherry drop = 4
P(cherry) = 4/14 = 2/7
Answer:P(Cherry) = 2/7
To find 20% of 950 you would set it up as a proportion. When doing percentages the prevent is always out of 100 so the first step would be 20/100. You are trying to find a number out of 950 so the second part would be ?/950. Now you want to cross multiply and divide. 20*950=19,000 then you divide it by 100 (your other number) 19,000/100=190. So 20% of 950 is 190.
Answer:
A) The mean of the chi-square distribution is 0
A) is not a property of chi square distribution.
Step-by-step explanation:
We have to find the properties of a chi square test.
A) False
The mean of a chi square distribution is equal to the degree of freedom.
B) True
The chi-square distribution is non symmetric.
C) True
The chi square value can be zero and positive.
It can never be negative because it is based on a sum of squared differences .
D) True
The chi-square distribution is different for each number of degrees of freedom.
When we are working with a single population variance, the degree of freedom is n - 1.
Vineet can conclude that:
B ) the system of equations does not have a solution.
(32x⁴ - 12x² + 7x) / 2x
32x⁴/2x - 12x²/2x + 7x/2x
16x³ - 6x + 7/2
