Answer:

 Slope = 0.222/2.000 = 0.111

 x-intercept = -3/1 = -3.00000

 y-intercept = 3/9 = 1/3 = 0.33333

Step-by-step explanation:

Step  1  :

Equation of a Straight Line

1.1     Solve   x-9y+3  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x-9y+3  = 0 and calculate its properties

Graph of a Straight Line :

 

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 1/3 so this line "cuts" the y axis at y= 0.33333

 y-intercept = 3/9 = 1/3  =  0.33333

Calculate the X-Intercept :

When y = 0 the value of x is -3/1 Our line therefore "cuts" the x axis at x=-3.00000

 x-intercept = -3/1  = -3.00000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 0.333 and for x=2.000, the value of y is 0.556. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.556 - 0.333 = 0.222 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.222/2.000 =  0.111

Geometric figure: Straight Line

 Slope = 0.222/2.000 = 0.111

 x-intercept = -3/1 = -3.00000

 y-intercept = 3/9 = 1/3 = 0.33333

What is the volume of a rectangular prism that has a length, width, and height of 1/2 m, 1/4 m, and 2/3 m, respectively?
Talja [164]
V = L * W * H
V = (1/2)(1/4)(2/3) 
V = (1 * 1 * 2) / (2 * 4 * 3)
V = 2/24 reduces to 1/12 m <===

A concert ticket that originally cost $46.50 is on sale for $38.75. What is the percent of decrease, rounded to the nearest tent
Arturiano [62]
You subtract 38.75 from 46.5, which is 7.75. 7.75/46.5=about .16666, or 16.7 percent.

In a study of the effect of handedness on athletic ability, participants were divided into three groups: right-handed, left-hand
inessss [21]

Answer:

Option A) Discrete and quantitative                                                          

Step-by-step explanation:

We are given the following situation in the question:

In a study of the effect of handedness on athletic ability.

Variable 1: Handedness - right-handed, left-handed, and ambidextrous

Variable 2:  Athletic ability measured on a 12-point scale.

Dependent Variable:

  • The dependent variable is the response variable and its value depends on the independent variable.
  • A change in independent variable leads to a change in the dependent variable.

For the given case the athlete ability is the dependent variable that depends on the independent variable of handedness.

Athletic ability is measured on a 12 point scale. thus, it can take numerical values from 0 to 12.

Thus, it is a quantitative variable.

Since theses values are always expressed in whole numbers and not in decimals so they cannot take all the values within an interval.

Thus, it is a discrete variable.

Option A) Discrete and quantitative

What is the number in the middle of -7 and 6
Anon25 [30]

Answer:

-0.5

Step-by-step explanation:

Use the average formula:

Sum of all numbers/Number of items

6 + (-7) / 2

= -1/2

So, the number in the middle of -7 and 6 is -0.5
