Answer:
10.75
Step-by-step explanation:
First you see how many times 4 can go into 4 in the tens place which is 1 .You multiply 4 times 1and you get 4 .Then you minus 4 from 4 and get
Then you bring down the 3 and see how many times 4 can go into 3 which is 0 .So you put a decimal point and bring down a 0.
See how many times 4 can go into 30,which will be 7 times.After , you multiply 7 times 4 and you get 28.Subtract 29 from 30 and you get 20.You bring down the 0 .
See how many times 4 can go into 20 which is 5.Mutiply 5 times 4 and get 20 then subtract 20 from 20.
Get a final quotient of 10.75.
The factors of 2 are 2, 1
The factors of 32 are 2,16 8,4 32,1
We see that (2*-4)-(1*-8)=-16
So the factored form is:
(2x-8)(x-4)
Answer:

Step-by-step explanation:
<u>QUESTION 1</u>
The given data set for the expenditure is
The formula for calculating the mean is given by,
We need to add all the expenditure and divide by the total number of days.
This gives us,
to the nearest hundredth.
<u>QUESTION 2</u>
The standard deviation of the data set is given by the formula;
This implies that,
This will give us,
to the nearest hundredth,
.
<u>QUESTION 3</u>
The variance is the square of the standard deviation.
To the nearest hundred gives,
Always eliminate the first one before moving on. Remember to drop down monomials, like you would a normal division problem.
2x² + 10x + 18
__________________
x + 3 | 2x³ + 16x² - 12x + 9
-(2x³ + 6x²)
-------------------------------
10x² - 12x
-(10x² - 30x)
-----------------------------
+ 18x + 9
- (18x + 54)
----------------------
-45
2x² + 10x + 18 R: -45/x + 3 is your answer R: = remainder
