Answer:

x + 8 + 12 + 11 = 43

Step-by-step explanation:

The perimeter is the length of the 4 sections of fencing.

If x represents the fourth section and the perimeter is 43, then

x + 8 + 12 + 11 = 43, that is

x + 31 = 43 ( subtract 31 from both sides )

x = 12

The length of the fourth section is 12 ft

Answer:

1. x^4 -x^3 -4x^2 -3

a1 = -7.4

an = an-1 -13.8  (choice 1)

Step-by-step explanation:

f(x) = x^4 -x^2 +9

g(x) = x^3 +3x^2 +12

We are subtracting

f(x) -g(x) =x^4 -x^2 +9 - ( x^3 +3x^2 +12)

Distribute the minus sign

x^4 -x^2 +9 -  x^3 -3x^2 -12

I like to line them up vertically

x^4      -x^2 +9

-  x^3 -3x^2 -12

-------------------------

x^4 -x^3 -4x^2 -3


2.  a1 = -7.4

To find the common difference, take term 2 and subtract term 1

-21.2 - (-7.4)

-21.2 + 7.4

-13.8

an = an-1 -13.8

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
