I think these are the sums of perfect cubes. 

A = (2x²)³ + (3)³
B = (x³)³ + (1)³
D = (x²)³ + (x)³
E = (3x³)³ + (x^4)³

In circle B with the measure of minor arc AC= 84°, find m
ELEN [110]

Answer:

m<ADC = 42°

Step-by-step explanation:

Based on the inscribed angle theorem, the inscribed angle, m<ADC is ½ the measure of minor arc AC.

If minor arc is given as 84°, therefore:

m<ADC = ½(84)

m<ADC = 42°

How would adding a score of zero affect the mean and mediam game scores
Nimfa-mama [501]

Answer:

Here is the complete question attached with.

The mean score would decrease more than the median score.

Step-by-step explanation:

The numbers for which we have to find the mean and median are:

60,70,80,80,100

Here the mean, \frac{Sum\ of\ all\ observations}{Number\ of all\ observations} =\frac{60+70+80+80+100}{5} =78

Median,=80 as median is the middle term if the observations are arranged in ascending order.

Now as the question says that we have to add a zero to see its effect.

So adding a zero we have

Mean =\frac{0+60+70+80+80+100}{6} =65

Median = \frac{70+80}{2} =75,as number of observations is even terms so we will add two middle numbers and divide it with 2.

So we can conclude that the mean is having more variation than the median.

Mean shows as variation of 78-65=13 where as Median shows a variation of 80-75=5 only.

So our final answer is option D that is "The mean score would decrease more than the median score."
