For this case, we must indicate which of the given functions is not defined for
By definition, we know that:
has a domain from 0 to infinity.
Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.
Thus, we observe that:
is not defined, the term inside the root is negative when .
While if it is defined for
, your domain is given by all real numbers.
Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.
So, we have:
with x = 0: is defined.
with x = 0: in the same way is defined.
Answer:
Option b
Answer:
The sample size 'n' = 384
Step-by-step explanation:
<u>Step(i)</u>:-
Given data the margin of error = 0.05
The margin of error of the estimation of a population proportion is determined by
<u><em>Step(ii)</em></u>:-
In data not given sample proportion 'p' but
we know that
cross multiplication, we get
0.05 ×√n = 0.98
<em>squaring on both sides, we get</em>
<em>n = 384.16≅ 384</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The sample size 'n' = 384</em>
Answer:
We need 29 more $10 donations to complete $600 amount.
Step-by-step explanation:
Amount of money asked for donation = $10
Total amount of donation needed = $600
Amount of donation collected = $310
Amount of donation to be collected = $600 - $310 = $290
Let the number of $10 donation needed be x.
We need 29 more $10 donations to complete $600 amount.
