Answer:
B
Step-by-step explanation:
Answer:
Slope of line =
Slope of parallel line =
Slope of perpendicular line = (-2)
Step-by-step explanation:
Slope of a line passing through two points and is,
Therefore, equation of a line passing through points (1, -3) and (-1, -4) will be,
If the slope of a line parallel to the given line is ,
Then by the property of parallel lines,
Therefore, slope of the parallel line will be .
Property of perpendicular lines,
Therefore, slope of the perpendicular line will be (-2).
Answer:
6.0
Explaination: this is because you round down if your number is smaller than 5. in this case it is.
Answer:
Step-by-step explanation:
a=0 and b=20 in the uniform density function
∴ the mean μ===10 and
the variance ==.
The standard deviation is the square root of the variance, so
Having determined the mean and standard deviation of the uniform distribution, we can conclude that follows a normal distribution with and .
The normal probability distribution is:
So, substituting and
Having approximated sum , we move on to the standardized sum , which is the same as only with μ=0 and σ=1. This means the probability distribution is the standard normal distribution, which is:
