To solve this question simply break down the variables and numbers one at a time.
Here the word a number can be used to describe any number so let’s call that a variable x.
Increased would be addition in mathematics.
Next put everything together.
5x + 6 = -2
5x = -8
X = -8/5.
This is the value of x
Answer:
The confidence interval is 
, in which n is the size of the sample.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of 
.
That is z with a pvalue of 
, so Z = 1.96.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 
The upper end of the interval is the sample mean added to M. So it is 
The confidence interval is , in which n is the size of the sample.
Answer: $181,500
Step-by-step explanation:
If amount paid for house and one acre of land = 165,000
Then, additional acre of land is 4.3 acres- 1 acre of land purchased with the house = 3.3 acres of land
If additional acre goes for 5,000 per acre
1 acre = 5,000
3.3 acres = 5,000 x 3.3 = $16,500
Total amount paid for the land and the land
= cost of house and land + cost of additional 3.3 acres of land
= 165,000 + 16,500
= $181,500
Using the place value chart we can see that the decimal 0.6 is six tenths, so we can write 0.6 as the fraction 
. Notice however that is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 10 which is 2.

Answer:
8/37
Step-by-step explanation:
First subtract 450 - 370.
450 - 370 = 80
Then put it into fraction form where the increase is the numerator and the cost from last year is the denominator.
80/370
Then, simply the fraction (if possible).
8/37
