Answer:

7/3 = 2 1/3

41/9 = 4 5/9

9/5 = 1 4/5

Step-by-step explanation:

You cannot put these fractions in simplest form, but instead a mixed number.

You can put any improper fraction into a mixed number by dividing the numerator by the denominator.

So, 7/3 can be divided. 7 divided by 3 is equal to 2 with a remainder of 1. When dividing to make a mixed number, take the remainder and put it as a fraction with the denominator being the divisor of your problem. Ex. 2 w/ a remainder of 1 would turn in to 2 1/3.

This same process applies for the other 2 as well.

I hope this helped :)

For the first one:

D) The perpendicular bisector of line MN

For the second one:

You need a protractor (angle ruler) to measure the angle. After finding the measurement, divide it into two. After finding the result, find the point that has that angle.

Example -

The pie measures 120°.

120° ÷ 2 = 60°

Find the point that measures 60° and connect the points (from the start to the edge of the pie).

For the third one:

C) m∠ABD ≅ m∠CBD

If outliers are discarded, then the retirement savings by residents of Econistan is normally distributed with a mean of $100,000

zavuch27 [327]

Answer:

$P(X>117000)=P(\frac{X-\mu}{\sigma}>\frac{117000-\mu}{\sigma})=P(Z>\frac{117000-100000}{20000})=P(z>0.85)$

And we can find this probability using the complement rule and the normal standard table or excel:

$P(z>0.85)=1-P(z$

The firgure attached illustrate the problem

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the retirement savings of a population, and for this case we know the distribution for X is given by:

$X \sim N(100000,20000)$
