How do I graph an inequality in one variable?

1 answer:

7 0

It depends on the variable.

If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).

Similarly for y, except it would be a horizontal line with either everything above or below shaded.

You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded

Answer:

n = -1.25

Step-by-step explanation:

S(ABCD) = AB × AD

S(ABCD) = 2n × (4n + 5)

S(ABCD) = CD × AD

2n × (4n + 5) = CD × (4n + 5)

n = -1.25

What is bigger 75 kg or 110 Ib?

Igoryamba

Those quantities can't be compared. "Kg" is a unit of mass,
whereas "lb" is a unit of weight. You can't convert mass to
weight without knowing the acceleration of gravity in the place
where the mass is.

For example:

-- 75 kg of mass weighs 418 lb on Jupiter.

-- 75 kg of mass weighs 62.6 lb on Mars

-- 75 kg of mass weighs 27.4 lb on the Moon.

-- 75 kg of mass weighs 165.3 lb on Earth.

-- 75 kg of mass weighs 11.1 lb on Pluto.

It all depends where you take your 75 kg.

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.
