Given that 
, and 
, this first step can be to make the equations equivalent to one another. As you can see, each equation is equal to a constant, e. Therefore, we can conclude that the equations can be equal to one another as well ( transitivity ).

Nice and simple question we have here! The step that can be used to find the solution should be 
.
Answer:
The margin of error is multiplied by 
Step-by-step explanation:
margin of error (ME) from the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic of the given confidence level
- s is the standard deviation of the sample (or of the population if it is known)
Since margin of error is proportional with inverse of 
,
if we cut the sample size in half, the margin of error is multiplied by .
Answer:
Is it too late to answer this?
Step-by-step explanation:
Answer:
The y-intercept is (0,-2)
Step-by-step explanation:
we know that
The <u><em>x-intercept</em></u> is the value of x when the value of y is equal to zero
The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero
In this problem we have that
The graph crosses the x axis at negative 10 and crosses the y axis at negative 2.
therefore
The x-intercept is the point (-10,0) and the y-intercept is the point (0,-2)
