You were really close :D
The mistake you made is that 44 - 36 is 8, not 6.
Using 8 instead, the answer is:
Answer:
46$
Step-by-step explanation:
20+20=40, 5% of 40=2, 42, +4, 46. (the 4 comes from the 10%)
Answer:
E
Step-by-step explanation:
Confidence Interval = mean + or - error margin
Mean = 42,000, error margin = width of estimate of the parameter ÷ 2 = 175 ÷ 2 = 87.50
We can be 95% confident that the population mean is 42,000 plus or minus 87.50
Answer:
or 
Step-by-step explanation:

The opposite of
is 

Convert decimal number −0.75 to fraction
.
Reduce the fraction
to lowest terms by extracting and canceling out 25.

Least common multiple of 4 and 5 is 20. Convert
and
to fractions with denominator 20.

Since
and
have the same denominator, add them by adding their numerators.

Add -15 and 8 to get -7

Convert decimal number 0.4 to fraction
. Reduce the fraction
to lowest terms by extracting and canceling out 2.

Least common multiple of 20 and 5 is 20. Convert
and
to fractions with denominator 20.

Since
and
have the same denominator, add them by adding their numerators.

Add -7 and 8 to get 1.

Least common multiple of 20 and 4 is 20. Convert
and
to fractions with denominator 20.

Since
and
have the same denominator, subtract them by subtracting their numerators.

Subtract 15 from 1 to get -14.

Reduce the fraction
to lowest terms by extracting and canceling out 2.

Answer:
Graphic is showed in the figure below
Step-by-step explanation:
To graph the equations given, let's do a table for positive values of x, and, by replacing it in the equation, let's calculate the value of y. Knowing the coordinate points (x,y) we can build the graphic.
<em>x y= x + 1/x² y = 1/x</em>
1 2 1
2 2.25 0.2
3 3.11 0.33
4 4.06 0.25
When x->0 both equations -> ∞, because lim(1/x) x->0 = ∞
The graphic is showed below. In red there is y = 1 + 1/x² and in blue y = 1/x
