<h3>Answer:</h3>

d. 4/229 +30/229i

<h3>Explanation:</h3>

Multiply numerator and denominator by the conjuate of the denominator, then simplify.

\dfrac{2}{2-15i}=\dfrac{2}{(2-15i)}\cdot\dfrac{(2+15i)}{(2+15i)}=\dfrac{4+30i}{2^2-(15i)^2}\\\\=\dfrac{4+30i}{4+225}=\dfrac{4}{229}+\dfrac{30}{229}i

Pie

Answer:

The expression to show the average daily change in temperature can be given by :

⇒ \frac{2.64-0.22-0.35+0.63}{4}°C

Step-by-step explanation:

Changes in the temperature of city as reported by newspaper :

Day 1: 2.64° C

Day 2: -\frac{2}{9}°C

Day 3: -0.35°C

Day 4: \frac{5}{8}°C

The average daily change in temperature can be calculated as

⇒ \frac{2.64-\frac{2}{9}-0.35+\frac{5}{8}}{4}°C

The fractions can be written in decimals

⇒ \frac{2.64-0.22-0.35+0.63}{4}°C

⇒ \frac{2.7}{4}°C

⇒ 0.675\°C\approx 0.68°C [Average daily change in temperature.]

A sample with which of these variances has a standard deviation that is greater than the variance?
White raven [17]
Since the standard deviation is the square root of variance. The only times where the standard deviation is greater than the variance is when the variance is between the values 0 and 1 exclusively. For example, the square root of 0.25 is 0.5.
