Theoretical probability determines the likelihood of some incidents to happen.
Theoretical probability is the ratio between the total number of possible outcomes and the desired outcome.
Here, the desired outcome is getting a 2 that is only one desired outcome, where as total possible outcomes are 6. Here, the probability of getting a 2 is.
Empirical probability depends on observance. In the given question, nothing related to observance of the given incident has mentioned, hence it is not empirical probability.
Every confidence interval has associated z value. As confidence interval increases so do the z value associated with it. The confidence interval can be calculated using following formula: Where is the mean value, z is the associated z value, s is the standard deviation and n is the number of samples. We know that standard deviation is simply a square root of variance: The confidence interval of 95% has associated z value of <span>1.960. </span>Now we can calculate the confidence interval for our income:
to find the mean, we must add al the numbers and divide it by n
that is,
164,175,178,166,167,145,176,150,174,162,180,156,173,158,182,184,160,172,186,168,195,169,171,187,170 we have to add al these numbers and divide it by 25
We can start from the given line's coefficients and translate the line from the origin to the given point. 4(x -(-2)) -(y -3) = 0 4x +8 -y +3 = 0
The equation of the desired line is ... 4x -y = -11
_____ For standard form line ax+by=c, any parallel line will have only a different value of c. For c=0, the line goes through the origin (0, 0). To make it go through point (h, k) we can write it as a(x-h) +b(y-k) = 0 which is completely equivalent to ax +by = ah +bk
