AfilCa [17]

Answer:

The correct answer is:

There is a positive correlation because women's weight tend to increase when height increases (D)

Step-by-step explanation:

The units that might be used to measure each variable are:

Height : meter (m) or foot (plural, feet) (Ft.)

weight : kilograms (kg) or Pounds (lb)

A positive correlation is said to occur between two variables when they both move in the same direction, that is, when they both increase or decrease, while a negative correlation occurs when the movement is not in tandem, i.e, as one increases, the other decreases. The relationship between height and weight is a positive correlation because, an increase in height, which is mainly as a result of elongation of bones, leads to an accumulated increase in total body mass, which in turn increases the body weight.

Subtract 7x^2−5xy+8y^2 from −2x^2−15xy+9y^2

Ghella [55]

Answer:

$y^2-10xy-9x^2$

Step-by-step explanation:

We want to subtract $7x^2 -5xy+8y^2$ from $-2x^2-15xy+9y^2$ .

We set up the subtraction problem as follows:

$(-2x^2-15xy+9y^2)-(7x^2-5xy+8y^2)$ .

We expand the brackets to obtain;

$=-2x^2-15xy+9y^2-7x^2+5xy-8y^2$ .

We regroup the terms to obtain;

$=9y^2-8y^2-15xy+5xy-2x^2-7x^2$ .

We now simplify to obtain;

$=y^2-10xy-9x^2$ .

Marlene rides her bike at a rate of 16 miles per hour. The time in hours that she rides is represented by the variable t, and th

White raven [17]

Let

t--------> the time in hours

d-------> the distance in miles

we know that

$d=16t$

this is a linear equation that represent the scenario

in this equation the independent variable is the time t and the dependent variable is the distance d

The distance's equation in function notation is equal to

$f(t)=16t$

Using a graph tool

see the attached figure

The domain of the function is the interval----------> [0,∞)

$t\geq0$

The range of the function is the interval-------> [0,∞)

$f(t)\geq0$

<u>Statements</u>

<u>a) The independent variable, the input, is the variable d, representing distance</u>

The statement is false

Because the independent variable is the variable t

<u>b) The distance traveled depends on the amount of time Marlene rides her bike</u>

The statement is true

Because the distance's equation in function notation is equal to

$f(t)=16t$

<u>c) The initial value of the scenario is 16 miles per hour</u>

The statement is false

Because $16$ represent the rate or the slope of the linear equation

<u>d) The equation t = d + 16 represents the scenario</u>

The statement is false

Because, the scenario is represented by the function $f(t)=16t$

<u>e) The function f(t) = 16t represents the scenario</u>

The statement is true
