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
Jon; he ran more in 2 hours than Maria did
Answer:
18°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
90° + 72° + ∠? = 180°
162° + ∠? = 180° ( subtract 162° from both sides )
∠? = 18°
Answer:
Step-by-step explanation:
8y + 11 = 4(y - 2)
8y + 11 = 4y -8
subtract 4y from both sides
4y + 11 = - 8
subtract 11 from both sides
4y = -11
divide by 4 on both sides
y = -2.75 or - y = 2.75
if you need a fraction it would be 2 3/4
