Slope of a = (3,-2) b = ( 7, 3 )
natali 33 [55]

Answer:

Down here VVVVVVVV

Step-by-step explanation:

The formula for slope is rise/run there a whole lot of variations of it tho see

(Srry abt my hand writing XD)

rise is basically how far away are the 2 y values from each other

(It will always be positive btw mate.

In this case the rise would be 5

because you need to move up 5 spaces to reach 3 from -2

Now the run which is how far away the 2 x values are from each other.

In this case it would be 4

because you need to move 4 spaces from 3 to reach 7

so it would the slope would be 5/4 :)

This may not be right but you can get the just of how to do it hopefully

Im learning this right now too XD

A sample of 25 undergraduates reported the following dollar amounts of entertainment expenses last year:
marin [14]

Answer:

Range = 85

\sigma = 28.71

Interval = [666.78, 781.62]

Step-by-step explanation:

Given

The data for 25 undergraduates

Solving (a): Range and Standard deviation

The range is:

Range = Highest - Least

From the dataset:

Highest = 772

Least = 687

So:

Range = Highest - Least

Range = 772-687

Range = 85

The standard deviation is:

\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}

First, calculate the mean

\bar x = \frac{769 +691 +............+715}{25}

\bar x = \frac{18105}{25}

\bar x = 724.2

So, the standard deviation is:

\sigma = \sqrt{\frac{(769-724.2)^2 +(691-724.2)^2 +(699-724.2)^2 +(730-724.2)^2 +............+(715-724.2)^2}{25}}

\sigma = \sqrt{\frac{20604}{25}}

\sigma = \sqrt{824.16}

\sigma = 28.71

Solving (b): The interval of the 95% of the observation.

Using the emperical rule, we have:

Interval = [\bar x - 2*\sigma, \bar x+ 2*\sigma]

Interval = [724.2 - 2*28.71, 724.2 + 2*28.71]

Interval = [666.78, 781.62]
