d/dx (2 x^2 y + y = 2x + 13)
4xy + 2x^2 y' + y' = 2
4xy + y'(2x^2 + 1) = 2
y' = (2- 4xy)/(2x^2 +1)
<span>ow we can use this in a linear equation for a slope
Ty = -5x/8 +5(3)/8 +8/8
= -5x/8 +(15+8)/8
= -5x/8 +23/8
this will gives us an approximation at x=2.8 now</span>
<u>Answer-</u>
The standard error of the confidence interval is 0.63%
<u>Solution-</u>
Given,
n = 2373 (sample size)
x = 255 (number of people who bought)
The mean of the sample M will be,

Then the standard error SE will be,


Therefore, the standard error of the confidence interval is 0.63%
1.You have that:
<span>
- One tin of 500 mL blue paint costs $11.50.
-Jason needs </span><span>4 L of blue paint.
2. First, you must convert 4 L to mL, as below:
1 L----1000 mL
4 L----x
x=4x1000/1
x=4000 mL
3. If 500 mL costs $11.50, h</span><span>ow much will it cost 4000 mL?
</span><span>
500 mL-----$11.50
4000 mL---x
x=(4000 mL)($11.50)/500 mL
x=$92.00
</span><span>
How much will it cost Jason to paint this bedroom?
The answer is: $92.00</span><span>

Given:
The recurring decimal is
.
To prove:
Algebraically that the recurring decimal
can be written as
.
Proof:
Let,


Multiply both sides by 100.
...(i)
Multiply both sides by 10.
...(ii)
Subtract (i) from (ii).


Divide both sides by 900.


So,
.
Hence proved.
