Points are: A= (-2,7)B= (3,5)C= (1,0) To show that the triangle is a right triangle, show that the sum of the squares of the len

Gala2k [10]

The sum of the squares of the lengths is 58

The square of length of the hypotenuse is 58

From the question, we have

AB² = (-2-3)² +(7-5)²= 25+4 =29

BC² = (3-1)²+(5-0)²=4+25=29

AC² = (-2-1)²+(7-0)² = 9+49 = 58

Here we can see that,

AB²+BC² = AC²

The sum of the squares of the lengths of two sides (the legs) equals the square length of the third side (hypotenuse).

the sum of the squares of the lengths = AB²+BC² =29+29 = 58

the square of length of the hypotenuse= 58

Pythagoras Theorem:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

Alex Ar [27]

The equation of the regression line is $\bar{y}$ =9.1006+(-0.2157)x and the point prediction of ammonium concentration for 25ml/h is $\bar{y}$ =3.7081

<h3>What is meant by regression line?</h3>

A regression line is an approximation of the line that describes the true, but unknown, linear connection between two variables. The regression line equation is used to predict (or estimate) the value of the response variable from a given value of the explanatory variable.

In statistical modeling, regression analysis is a collection of statistical techniques for estimating the associations between a dependent variable and one or more independent variables.

a) $\bar{y}$ =β₀+β₁x

Where,

β₁= $S_{xy}$ / $S_{xx}$ -------(1)

Where,

$S_{xy}$ = -341.959231

$S_{xx}$ 1585.230769

By substituting these values in equation 1 we get,

β₁= -0.2157

β₀= $\bar{y}$ -β₁x

Where,

$\bar{y}$ =∑ $y_{i}$ /n

∑ $y_{i}$ =52.8

n=13

Then,

$\bar{y}$ =4.0615

$\bar{x}$ =∑ $x_{i}$ /n

∑ $x_{i}$ =303.7

n=13

$\bar{x}$ =23.3615

β₀=4.0615-(-0.2157)(23.3615)

=9.1006

Therefore, β₀=9.1006

The regression equation is $\bar{y}$ =9.1006+(-0.2157)x

If x=25,

$\bar{y}$ =9.1006+(-0.2157)(25)

$\bar{y}$ =3.7081

damaskus [11]

Hi there,

So lets look at this problem. Ron has 20 pennies. Pam has 20 pennies. If Ron has 4 groups each group will have 5 pennies to add up to 20. Pam will have 5 groups and each group will have 4 pennies to add up to 20.

Therefore Ron will have more pennies in his group.
