Answer:
y = -1/4x + 1
Step-by-step explanation:
that is (0,1) and (4,0)
gradient
can be -1/4
c can be y = mx + c
we'll take anyone of the equation
1 = 0 + c
c = 1
The exponential growth formular is given by
where: P is the population of the country, t years after the initial year (i.e. in this case, 1994).
is the initial population of the country (i.e. the population of the country in 1994).
r is the growth rate of the population and
t s the number of years after the initial year.
We obtain the value of r by comparing the growth between 1994 and 1998.
Here: P = 146,
, and t = 4 years
Thus
To estimate the population of the country in 2011, we note that 2011 is 17 years after 1994.
Thus, the population of the country in 2011 can be estimated to be
million
Therefore, the population of the country in 2011 can be estimated to be 167 million to the nearest million.
Well, it would be 2/3 x 6, which you could 2/3 x 6/1 and then it would be 12/3 which would equal 4. This can also be proven through inspection, since 2/3's of 6 is 4 because 1/3 of 6 is 2.
Answer [4]
Answer:
9) x = 4 D)
10) x = 7 B)
Step-by-step explanation:
9)
Vertical angles are congruent.
23x - 2 = 90
23x = 92
x = 4
10)
Vertical angles are congruent.
18x - 6 = 1 + 17x
x = 7
Answer:
Step-by-step explanation:
Independent Variable
The independent variable is the condition that you change in an experiment. It is the variable you control. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment. Sometimes you may hear this variable called the "controlled variable" because it is the one that is changed. Do not confuse it with a "control variable," which is a variable that is purposely held constant so that it can't affect the outcome of the experiment.
Dependent Variable
The dependent variable is the condition that you measure in an experiment. You are assessing how it responds to a change in the independent variable, so you can think of it as depending on the independent variable. Sometimes the dependent variable is called the "responding variable."
