You get a complex fraction and you then have to "copy, dot, flop"

For example, (1/2)/5
To solve this, you would change it to 1/2 x 1/5 to get .1

The numerator multiplies by the whole number, for example 3/4 divided by 5 = 3/20 because 4 x 5 = 20.

3.Which of these scatterplots shows no correlation?
Artemon [7]
This is an unanswerable question there are no graphs for us to look at.

But if the points are scattered randomly and you can’t make up if it’s going left to right or right to left then it’s no correlation.

About % of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9 and z = 0.9 z = 0.9 (or w
prisoha [69]

Using the normal distribution, it is found that 63.18% of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The area within 0.9 standard deviations of the mean is the <u>p-value of Z = 0.9(0.8159) subtracted by the p-value of Z = -0.9(0.1841)</u>, hence:

0.8159 - 0.1841 = 0.6318 = 63.18%.
