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

3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
(divided both sides by -3z)
z=
If your question is what the value of the number you started with the answer would be 30. to find it you add 48 to -18 and you get 30.
Answer:
Adding and Subtracting Polynomials. When adding and subtracting polynomials , you can use the distributive property to add or subtract the coefficients of like terms. Use the commutative property to group like terms. (Recall that "like terms" are monomials with the same variables, such as 3 x 2 y and 82 x 2 y .)
