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

A bicycle rider increases his speed from 5 m/s to 15 m/s in 10 seconds

valentina_108 [34]

To find the acceleration of the bicycle rider, we are going to use the acceleration formula: $a= \frac{v_{f}-v_{i}}{t}$
where
$a$ is the acceleration
$v_{i}$ is the initial speed
$v_{f}$ is the final speed
$t$ is the time

We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore, $v_{i}=5$ , $v_{f}=15$ , and $t=10$ . Lets replace those values in our formula:
$a= \frac{v_{f}-v_{i}}{t}$
$a= \frac{15-5}{10}$
$a= \frac{10}{10}$
$a=1$

We can conclude that the acceleration of the bicycle rider 1 m/s^2
