Answer:
The answer is in the word document
According to the 3:1 ratio, you expect, out of a population of 1000 people, 750 non-hemophilia and 250 hemophilia.
The chi-square value can be calculated by the formula:
where:
O = observed value = 210
E = expected value = 250
Therefore:
χ² = (210 - 250)² / 250
= 6.4
Now, look at a χ<span>² distribution table, in order to find the p-value. In this case, you have only 1 degree of freedom and the closest </span>χ<span>² is 6.6 which corresponds to a p-value of 0.01.
Since p < 0.05, which is the minimum value generally accepted, we can say that the data do not support the hypothesis.</span>
Answer:
Equation of parabola: 8*(y - 2) = (x - 3)^2
or
y = (1/8)*(x - 3)^2 + 2
Step-by-step explanation:
focus at (3,4) and its directrix y = 0.
Focus equation: (h, k + c) = (3, 4)
Directrix equation y = k - c = 0
so h = 3, k + c = 4, k - c = 0
Solve the system : k + c = 4 and k - c = 0
add the equations together: k + c + k - c = 4 + 0
2k = 4
k = 2
so k + c = 4, 2 + c = 4, c = 2
4c (y - k) = (x - h)^2
4*2 *(y - 2) = (x - 3)^2
8*(y - 2) = (x - 3)^2
Answer: The 31st term is 367
Step-by-step explanation: An arithmetic sequence is derived such that every term is calculated by adding a common difference to the previous term.
The first term has been given as 12. And the value of the nth term shall be defined by the formula
nth term = a(n - 1) + 7. So in order to calculate the unknown term, simply substitute the term for n.
To calculate the 31st term, we apply the formula as follows
nth = a(n - 1) + 7
31st = 12(31 - 1) + 7
31st = 12(30) + 7
31st = 360 + 7
31st = 367
Therefore, the 31st term is 367
Ok so take -79 and add it too -83 so -83 + 79 to get your answer of H= what ever answer you get
