Answer:
Triangle ABC is similar but not congruent to Triangle XYZ
Step-by-step explanation:
When you dilate the size changes but the angles are the same with makes them similar and since the size of the triangles are different they cannot be congruent.
Using the empirical rule 68% would fall within one standard deviation of the mean.
The standard deviation is given as 2 inches and the mean is 49 inches.
Since it is only one standard deviation find the lower number by subtracting the standard deviation from the mean and find the higher number by adding the standard deviation to the mean.
49 - 2 = 47
49 + 2 = 51
68% would be between 47 inches and 51 inches tall.

The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
Step-by-step explanation:
the longest spin of a basketball on one finger is 255 minutes.
We need to find how many hours is that.
So, we need to convert 255 minutes into hours.
We know that,
60 minutes = 1 hour
Using Unitary method:
60 minutes = 1 hour
1 minute = 1/60 hour
255 minutes = 1/60 * 255 hour
255 minutes = 255/60 hour = 4.25 hour
255 minutes is 4.25 hour.
So, The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
