Answer:
a) The sample size of two possible without replacement is 10
b) The population mean is 4.8 shutdown.
The population mean and the sample mean are the same.
Step-by-step explanation:
An image is attached showing the step by step solution.
a) This is a combination problem. We did 5 combination 2 to get 10 possible samples.
b) We generate the possible sample and find their means. Then find the mean of the sample mean which is also the same as the population mean.
To determine if the line is parallel, perpendicular, or neither to the given line, we must compare their slopes.
Given equation: y = -2x + 3
slope = -2
The equation of the line can be calculated by -a/b of the standard equation.
(1) y = 2x - 1 , slope = 2
Since, this is just the negative of the given line, the lines are neither parallel nor perpendicular.
(2) y = -2x + 5, slope = -2
Since the slope is equal to that of the given equation, this line is parallel with the given equation.
(3) y = 12x + 7 , slope = 12
Since the slope do not have a special relation to the slope of the given line, it is neither parallel nor perpendicular to the given.
Answer:
17/24
Step-by-step explanation:
First find a common denominator which is 24 then times the top number by the bottom number
<span>For f(x)=4x+1 and g(x)=x^2+5
(f+g)(x) = </span>4x +1 + x^2 + 5
(f+g)(x) = x^2 + 4x + 6
