Perform the indicated operation (-2i+3i)+(-1-4i)

Shtirlitz [24]

Answer:

-1 -3i

Step-by-step explanation:

It is unusual to have two imaginary terms grouped together like this. Taking the question at face value, we treat i as though it were a variable, and collect terms in the usual way.

(-2i +3i) +(-1 -4i) = i(-2+3-4) -1 = -1 -3i

Answer:

No.

Step-by-step explanation:

As x increases 2^x will grow faster than 5 x^2. This is because the x in 2^x is an exponent and its graph grows very steeply compared with 5x^2 , as x increases.

For example when x = 10

5x^2 = 5*10^2 = 500

2^x = 2^10 =1024

When x = 11:

5x^2 = 605

2^x = 2048 and the difference will continue to increase.

When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus

Blababa [14]

Answer:

By the Empirical Rule, $\pm 3\sigma$

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

The symbol of a standard deviation is $\sigma$ . So

When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus how many sigma?

By the Empirical Rule, $\pm 3\sigma$
