Equation of a line passing through point (x1, y1) with slope m is given by y - y1 = m(x - x1)
For parallel lines, the slope of the required line is equal to the slope of the given line.
x = -3 is a vertical line, therefore, the required line will also be a vertical line since they are parallel.
Since the required line passes through point (4, 2), the equation of the required line is x = 4.
Answer:
The mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.
Step-by-step explanation:
We know the population mean and standard deviation, that has a bell-shaped distribution:
The sampling distribution, the distribution of the mean of samples of size n out of this population, will have the same mean as the population mean.
The standard deviation will be related to the population standard deviation and the sample size as:
Then, the mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.
Answer:
Step-by-step explanation:
favorable events=x
total number of events=x+y
P=(favorable events)/(total number of events)=x/(x+y)
