Answer:

Simplification of algebric expression is \frac{x^{2} - 2x^{3}-4 }{x^{2} }

Step-by-step explanation:

Simplify any algebric expression means to write an equivalent expression in which all similar terms combined and remove all symbols such as brackets.

The given algebraic equation is x^{2} -\frac{4}{x^{2} } +2x

now for simplifying it

First of all take L.C.M of x^{2}

= \frac{x^{2} (x^{2}) -4 + 2x(x^{2} )}{x^{2} }

We get \frac{x^{2} -4+2x^{3}}{x^{2} }

Further we can write it as  \frac{x^{2} - 2x^{3}-4 }{x^{2} }

Simplification of algebric expression is \frac{x^{2} - 2x^{3}-4 }{x^{2} }

If the mean of a normally distributed population is -10 with a standard deviation of 2, what is the likelihood of obtaining a va
ira [324]

Answer:

93.32% probability of obtaining a value less than or equal to -7.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = -10, \sigma = 2

What is the likelihood of obtaining a value less than or equal to -7?

This is the pvalue of Z when X = -7.

So

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

Z = \frac{-7 -(-10)}{2}

Z = \frac{3}{2}

Z = 1.5

Z = 1.5 has a pvalue of 0.9332.

So there is a 93.32% probability of obtaining a value less than or equal to -7.

How many times can 4500 go into 5 ?
Ilya [14]
Since we have 2 zeros we can take them off and add them back on when we are done.

5 goes into 45 9 times.

now lets add the two zeros back on

900

5 goes into 4500 900 times
