Answer:
From <u>fourth</u> month onwards, the growth rate of 
is greater than that of 
.
Step-by-step explanation:
Given:
The growth rates of both bank accounts are given as:
Now, as per question, we need to find the value of 'x' when the value of 
. Or,
Now, we can do this by checking the values of 'x' by hit and trial method.
Let 
. The inequality becomes:
Let 
. The inequality becomes:
Let 
. The inequality becomes:
Let 
. The inequality becomes:
Therefore, the value of 'x' for which is 4.
So, from the fourth month onwards, the balance in becomes greater than .
The graphical solution is shown below to support the same.
From the graph, we can conclude that after the 'x' value equals 3.4, the graph of lies above of . Hence, for 
No because
48 times 53=2544
his estimate is way off- it is off by (2544-250)= 2294
True because tan(20)=2.1 and cot(20)=is o.44
The coefficient of 2xy3 is 2
Answer:
0.1151
Step-by-step explanation:
Given that a laptop company claims up to 10.1 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. A survey on battery life reported by customers shows that it follows a normal distribution with mean 9.5 hours and standard deviation 30 minutes.
If X is the battery life then X is N(9.5, 0.5)
(we convert into one unit for calculations purpose here hours)
a) the probability that the battery life is at least 10.1 hours
=
we get the probability that the battery life is at least 10.1 hours is 0.1151
