Answer:

-2\sqrt{a}

Step-by-step explanation:

\lim_{x \to a} \frac{a-x}{\sqrt{x} -\sqrt{a} } \\ =-\lim_{x \to a} \frac{x-a}{\sqrt{x} -\sqrt{a} }  \\=-\lim_{x \to a} \frac{(\sqrt{x} -\sqrt{a})(\sqrt{x} +\sqrt{a})}{\sqrt{x} -\sqrt{a} }  \\=- \lim_{x \to a} \sqrt{x} +\sqrt{a}\\=-2\sqrt{a}

5(x – 2) – X – 5 = -3
Mashutka [201]

Answer:

5(x-2) - x - 5 = - 3

5x - 10 - x - 5 = -3

4x - 15 = -3

4x = -3 + 15

4x = 12

x = 12/ 4

Therefore x = 3.

(1990). (2010)
wel

The statistical information is that in 1990, there was 150 auto theft per population over 178 cities.

<h3>Interpreting the statistical information </h3>

The information also shows that 50% of the cities had a theft rate of less than 117 per population while the reaming 50% of the cities had a rate above that level.

A standard deviation of 12 means that individual cities could have had crime rates as low as 114 and as high as 186.

In 2010, the crime rate over 178 cities averaged 125 per I lakh population. The remaining half had a theft rate of less than 123 while the reaming half recorded a rate above that level.

A standard deviation of 7 means that individual cities could have had crime rates as low as 104 and as high as 146.

On a comparative note, both the average and standard deviation recorded a significant reduction. The standard deviation experienced a huge reduction of more than 40%. This means that the combined measure came down from 8.14% in 1990 to 5.6% in 2010.

The shape of the distribution depicts a sizable shift to the left along with an appreciable compression of the spread.
