Using z-scores, it is found that the value of z is z = 1.96.

Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula, which for a measure X, in a distribution with mean
and standard deviation
, is given by:
- It measures how many standard deviations the measure is from the mean.
- Each z-score has an associated p-value, which is the percentile.
- The normal distribution is symmetric, which means that the middle 95% is between the <u>2.5th percentile and the 97.5th percentile</u>.
- The 2.5th percentile is Z with a p-value of 0.025, thus Z = -1.96.
- The 97.5th percentile is Z with a p-value of 0.975, thus Z = 1.96.
- Thus, the value of Z is 1.96.

Answer:
4(10)-5=35
Step-by-step explanation:
4(10)=40-5=35
4(10) is the same as 4x10
So think about it like 4x10-5

Hi! We are given the limit expression:

If we directly substitute x = 2 then we get 0/0 which is an indeterminate form. Therefore, we need to find other methods to evaluate the limit that does not become an indeterminate form.
As for rational function with square root in it, we conjugate the expression by multiplying both denominator and numerator with the square root expression.

When two same square root expressions multiply each other, the square root is taken out as shown above.
From denominator, we can factor x²-4 to (x-2)(x+2) via differences of two squares.
Hence:

Cancel x-2.

Then substitute x = 2 which we receive 0/4 = 0.
Henceforth, the limit value of expression is 0.
