18 2/5 - n = -10 1/3

Wewaii [24]

Answer:

The answer is $n=28\frac{11}{15}$ .

Step-by-step explanation:

Given:

18 2/5 - n = -10 1/3.

Now, to solve the equation:

$18\frac{2}{5} - n = -10 \frac{1}{3}$

Converting the mixed fractions to improper:

⇒ $\frac{92}{5} -n=-\frac{31}{3}$

Moving the numbers on one side and variable to the other:

⇒ $\frac{92}{5} +\frac{31}{3}=n$

Now, solving the factions:

⇒ $\frac{92\times 3+31\times 5}{15}=n$

⇒ $\frac{276+155}{15}=n$

⇒ $\frac{431}{15}=n$

⇒ $28\frac{11}{15}=n$

Therefore, the answer is $n=28\frac{11}{15}$ .

A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degr

Natalija [7]

Answer

:we are told that every year the temperature rises by 0.08degrees Centigrade,

So the difference between margin of error and the increase is much higher

That is

0.15-0.08=0.07

But remember Margin of error=Critical value *Standard deviation of population

And it is a quantity that measures accuracy

So the counter argument is that this is still an increase and it should be considered.

Explain to a new student how a reflection across the y-axis changes the coordinates of the original point.

RSB [31]

If you were to have (3,2) and find the reflection of the y axis, it would turn y into a negative, making it (3,-2).
