Answer:
True.
Step-by-step explanation:
We have been given a statement. We are asked to determine the given statement is true or false.
Statement: Areas under the standard normal curve cannot be negative, whereas z-scores can be positive or negative.
We know that area under the standard normal curve is equal to 1, so area under normal curve cannot be negative.
We know that a z-score represents that a data point is how many standard deviation above or below mean.
When a data point is less than mean, then z-score will be negative and when a data point is greater than mean, the z-score will be positive.
Therefore, our given statement is true.
2(n-7) = 3(n+7)
2n-14 = 3n + 21
-35 = n (answer)
Is there an answer to this equation such as 2x-3+8=4?
The answer is 30
Explanation:
So all of the angles in a triangle add up to 180 degrees and so if you split the triangle into separate triangles then you can add up the angles that are known and subtract from 180 to get the size of the missing angle e.g 90 + 56 = 146, 180 -146 = 34 for the other triangle 90 + 26 = 116, 180 - 116 = 64 and so 64 - 34 = 30
