Scores on a dental anxiety scale range from 0 (no anxiety) to 20 (extreme anxiety). the scores are normally distributed with a mean of 11 and a standard deviation of 4. find the z-score for the given score on this dental anxiety scale.

Step-by-step explanation:

The following information is missing in the question:

We have to find z-score for the given score on this dental anxiety scale: 12, 6

We are given the following information in the question:

Mean, μ = 11

Standard Deviation, σ = 4

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

where x is the given score on this dental anxiety scale.

For x = 12

For x = 6

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

he has now walked a total of what?

if i know what this is maybe i can
