How to solve equations with variable in denominator?

1 answer:

4 0

In general you can multiply through by the LCD

For example solve :-

2/x + 1 / (1+ x) = 11/12

The LCD is 12x(x + 1).

Now we multiply each term by 12x(x + 1)

2*12(x+1) + 12x = 11x(x + 1)

and this is solved in the usual way.

A study was done that looked at how much red meat people consumed and how long they lived. The correlation r was found to be 0.9

AVprozaik [17]

Answer:

False

Step-by-step explanation:

Since the correlation r was found to be 0.98 (a value closer to 1).

Let X =how much red meat people consumed

let Y = how long they lived.

where the x-values are the values of the deviations of co-ordinates X from Xₙ, their mean value and the y-values are the values of the deviations of co-ordinates Y from Yₙ, their mean value.

That is, x=(X−Xₙ) and y=(Y−Yₙ).

The results of this determination give values of r lying between +1 and −1, where;

+1 indicates perfect direct correlation,

−1 indicates perfect inverse correlation and

0 indicates that no correlation exists.

Between these values, the smaller the value of r, the less is the amount of correlation which exists.

Generally, values of r in the ranges 0.7 to 1 and −0.7 to −1 show that a fair amount of correlation exists.

therefore, it can be seen that there is a perfect relationship between the quantity eaten and how long the person live

But, the correlation does not consider those that does not consume meat, and it is very hard to determined the answer to the question.

the answer is false because there are other reasons that determined longevity of life apart from meat consumption.

If if Spencer spent a total of $704.00 in the month of July, which is the best estimate for the amount of money he spent on clot

Maksim231197 [3]

Answer:

$Clothing = \$190.0$

Step-by-step explanation:

Given [Missing details]

Spencer's expenses

$Clothing = 27\%$

$Gasoline = 11\%$

$Food = 44\%$

$Entertainment = 18\%$

$Total= \$704.00$

Required:

An estimate for the amount spent on clothing

To do this, simply multiply the clothing percentage by the total amount.

$Clothing = 27\% * \$704.00$

$Clothing = 0.27 * \$704.00$

$Clothing = \$190.08$

Approximate

$Clothing = \$190.0$

When the outliers are removed, how does the mean change?

jok3333 [9.3K]

<span>In statistics, an outlier is an observation point that is distant from other observations.

Given the points
15, 23, 24, 26, 27 and 35

Notice, that the points 15 and 35 are distance from the other points and hence are outliers.

The mean of the observations including the outliers is given by
$\frac{15+23+24+26+27+35}{6} = \frac{150}{6} =25$

The mean of the observations without the outliers is given by
$\frac{23+24+26+27}{4} = \frac{100}{4} =25$

Therefore, </span>when <span>the outliers are removed, the mean remains the same.</span>
