This question is incomplete. There are options in the question (from reference) and no highlight in the red bolded text in the question.
What effect does decreasing the temperature of a room have on a lifespan of a battery?
Which variable is highlighted in red, bolded tex?
a
. Independent
b
. Dependent
c
. Control
d
. None
But the answer to both the independent and dependent variables will be provided and explained in detail.
Answer:
Independent variable: decrease in temperature
Dependent variable: lifespan of battery
Step-by-step explanation:
The independent variable in an experiment is defined as the variable that can be changed or manipulated in order to find an outcome while the dependent variable is defined as the variable that is influenced by the changes in the independent variable.
In the given example, a decrease in temperature is the dependent variable as it is changing and the lifespan of battery is the dependent variable as it is responding to the independent variable ?9decrease in temperature).
Answer:
The undefined terms which are used to define a ray is:
Point and a line.
Step-by-step explanation:
The undefined terms in coordinate geometry are:
Line, Points and Plane.
since a line do not have any length, Point has a location but no size.
A line has no width and it extends infinitely and is one dimensional.
and a plane extends infinitely in both the dimensions.
<em>Ray:</em>
<em>A ray is part of a line, has one fixed endpoint, and extends infinitely along the line from the endpoint.</em>
Hence, the undefined terms which are used to define a ray is:
Point and a line.
Answer:
B,C, and E
Step-by-step explanation:
A histogram is a graphical illustration of information in bars of diverse heights. A histogram displays the shape and spread of continuous sample data. The true statements about the data essay scores for high school sophomores and juniors in a contest are; the juniors tended to have higher essay scores than the sophomores, the medians of both data sets are equal and the histogram is the best way to show that both distributions are nearly symmetric.
