I think the answer Is A & C, What do you think the answer is, please hurry.

One side of a rectangle is five times as long as the other side. If the perimeter is 72 meters, what is the length of the shorte

Yakvenalex [24]

6 meters

72 = x+x+5x+5x
72 = 12x
6 = x
the shorter side is 6 meters

If two polynomial equations have real solutions, then will the equation that is the result of adding, subtracting, or multiplyin

kirill115 [55]

No. A polynomial equation in one variablel ooks like P(x) = Q(x), where P and Q are polynomials.

Consider polynomial equations x^2 = 3 and x^2 = 1.

Obviously they have real solutions.

Subtract the two polynomial equations:

(x^2 - x^2) = (3 - 1)

0 = 2...

We get the polynomial equation 0 = 2. We call this a polynomial equation because single constants are also by definition polynomials.

Obviously 0 = 2 has no real solution.

Find the area of each figure. Round to the nearest hundredth where necessary.

Papessa [141]

Answer:

The answer to your question is Triangle's area = 520 in², Square's area = 576 in²

Step-by-step explanation:

Process

1.- Calculate the area of the triangle

-Find the length of the base using the Pythagorean theorem

c² = a² + b²

-Solve for b²

b² = c² - a²

-Substitution

b² = 37² - 35²

-Simplification

b² = 1369 - 1225

b² = 144

b = 12 in

-Find the base

base = 2(12) = 24 in

-Find the area of the triangle

Area = base x height / 2

-Substitution

Area = 24 x 35 / 2

-Simplification

Area = 420 in²

2.- Find the area of the square

Area = side x side

-Substitution

Area = 24 x 24

-Result

Area = 576 in²

For which data set is a linear regression most reasonable?

Oxana [17]

Answer:

The correct option is;

A. A set of nine data pairs with a correlation coefficient r = -0.4

Step-by-step explanation:

In statistical analysis, it is important to make use of an adequate sample size in order to arrive at a valid result. An analysis with a very small sample size can provide misleading results

When performing regression analysis it is generally accepted by researchers that each variable should have at least 10 observations.

Therefore, the data set having nine data pairs with a negative correlation of -0.4 will provide the most valid result that can then be used for generalization about the larger statistical population.
