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).
The probability that a student participates in both sports and drama is 
.
<h3>What is the formula for P(AUB), where A and B are any two events?</h3>
If 
and 
are any two events, then the probability of the joint event 
is given by the following formula: 
Given that 42% of the students participate in sports and 25% of the students participate in drama and 53% of the students participate in either sports or drama.
Suppose 
denotes that "a student participates in sports" and 
denotes that "a student participates in drama".
So, we have 
, 
, 
.
We want to find the probability that a student participates in both sports and drama i.e., we want to find 
.
By the above formula, we obtain:
Therefore, the probability that a student participates in both sports and drama is .

You need to divide the miles by the hours to et the Average speed.
M divided by h = s
Because to get the mph (miles per hour) you multiply the average speed to the hours.
S•h=mph

the triangle is right as it has a right angle as one of the 3 angles
the triangle is isosceles as it has 2 equal sides , indicated by the score on the equal sides and 2 equal base angles of 45°
