50% of data will be less than 50
Step-by-step explanation:
A normal distribution has the shape of the graph like a bell.
Given

we have to find how much data will be less than 50.
So we have to calculate z-score for 50.

The z-score is zero. As we have to find the number of values less than 50 we will find the area to the left of curve

In order to convert the probability into percentage
=0.50*100
=50%
Hence,
50% of data will be less than 50
Keywords: Probability, Area under the curve

Perimeter is when you add the outside of a shape.
For example: if you are finding the perimeter of a rectangle the formula is P= l+w+l+w. I hope this helps !
I think that the answer is ( 4.5) !!
Based on the given fractions above which are 7/8 and 42/4, in order for us to know if they are both proportional is to do the cross multiplication. Let's say, we multiply 4 by 7 and we get 28. Divide 28 by 8 and the result is 3.5 and not 42. Therefore, we can say that these fractions are NOT proportional. Hope this helps.
