Ratios can be described in different ways, if you were given a fraction such as 2/4 then we would put in 3 ways like 2/4, 2:4, and 2 to 4. So basically in any rule with fractions or anything else like that you'd have to explain it in 3 ways like my example shows.

Hopefully this helped. :)

Which visualization tool is more helpful for detecting outliers in data? Select one: a. scatter plot b. histogram c. Boxplot

Tpy6a [65]

Answer:

(A) Scatterplot

Step-by-step explanation:

The most helpful visualization to spot outliers would be a scatterplot.

When collecting data on a scatterplot, you can see how the results are similar and which areas have the most answers and such.

There can be multiply outliers on a scatterplot, and they stand out because while most answers will be clumped together, the outliers will not.

marshall27 [118]

Answer:

The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.

Step-by-step explanation:

The least square regression line is used to predict the value of the dependent variable from an independent variable.

The general form of a least square regression line is:

$\hat y=\alpha +\beta x$

Here,

y = dependent variable

x = independent variable

α = intercept

β = slope

The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:

$\hat y=3.73 +0.88 x$

Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:

$\hat y=3.73 +0.88 x$

$=3.73 +(0.88\times 70)\\=3.73+61.6\\=65.33$

Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
