Determine the probability P (3) for a binomial experiment with n = 12 trials and the success probability p=0.2. Then find the
mean, variance, and standard deviation.
Part 1 of 3
Determine the probability P (3). Round the answer to at least three decimal places.
P(3)=0
Part 2 of 3
Find the mean. If necessary, round the answer to two decimal places.
The mean is
Part 3 of 3
Find the variance and standard deviation. If necessary, round the vanance to two decimal places and standard deviation to
at least three decimal places.
The variance is
The standard deviation is

And employee salary increased by $4500 which represents a 15% raise what is the rate of the increase

Based on what i know about mean, this doesn't add up.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
