Answer:
Normal distribution is a Continuous distribution.
Step-by-step explanation:
Normal Distribution:
The following information is true about normal distribution.
- Theoretically, the mean, median, and mode are the same.
- Its parameters are the mean, mu, and standard deviation, sigma.
- About two thirds of the observations fall within plus or minus 1 standard deviation from the mean.
But normal distribution is not a discrete distribution. It is a continuous distribution.
- The normal distribution is a continuous probability distribution. This has several implications for probability.
- The probability that a normal random variable X equals any particular value is 0.
The angle measure is 78/2 degrees. that would simplify down to 39 degrees. I don't remember the theroem but I do know that the angle is half the side length angle measure
1/4(2x-14)=4
2x/4-14/4
X/2-7/2=4
x-7/2=4
8=x-7
8+7=x
X=15
Factor it out first so:
y=(x+13)(x-2)
Then you know that x= -13 and 2 to make the equation 0
Hope this helps!
