Answer:
Option B) is a continuous probability distribution
Step-by-step explanation:
Properties of a normal probability distribution:
- The mean, mode and median of the data is same.
- It is a continuous probability distribution.
- The area under the curve is 1.
- The probability that any random variable X at a particular value is zero.
Thus, from the properties of normal distribution, the correct answer is:
Option B) is a continuous probability distribution
Answer:

Step-by-step explanation:
We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).
Note that x=1 is a <em>vertical line </em>since x is 1 no matter what y is.
This means that if our new line is perpendicular to the old, then it must be a <em>horizontal line</em>.
So, since we have a horizontal line, then our equation must be our y-value of our point.
Our y-coordinate of our point (8,-9) is -9.
Therefore, our equation is:

And this is in standard form.
And we're done!
Answer:
No solution.
Step-by-step explanation:
6(n −1) + 2 = n(4 + 2) + 4
6n - 6 + 2 = 6n + 4
-4 = 4 (inconsistency)
The price increased so it would be a positive net change.
Subtract the new price from the original price:
45.83 - 30.46 = 15.37
The net change was C. $15.37
Answer:
X=-8
Step-by-step explanation:
A number x is multiplied by 4, added to 3, and then divided by x+2, leaving us with 7/2. Or, as an equation:

Now, let's cross multiply:


And solve:
