Answer:
the population would be 30.28 billion by 2020
Step-by-step explanation:
y=6.08 + 1.21x
y = 6.08 + 1.21(20)
y = 6.08 + 24.2
y = 30.28

Answer:
26.8336 ≈ 26.83
Step-by-step explanation:
If x < 5, then we round down.
If x ≥ 5, then we round up.
2 decimal places is the hundredths place.
26.83<u>3</u>6
3 < 5, so we round down
26.83
Answer:
The Median is 5
Step-by-step explanation:
The median is the middle number in a set of data, when the data has been written in size order.
0 1 2 4 <u>5 5</u> 5 6 6 6
As there is an even number of data the median is the average of the middle two values. As the middle 2 values are both 5, then the average of these is also 5. Therefore, the median is 5.
To find the mean of the set of data, add all the values together then divide by the number of data values:
(0 + 1 + 2 + 4 + 5 + 5 + 5 + 6 + 6 + 6) ÷ 10 = 4
Therefore, the mean is 4.
The Median is a better measure of central tendency as extreme values (outliers) do not affect it. From inspection of the dot plot, the majority of the data values are 5 and 6. Therefore, the lower values *could* be outliers, so 5 is a more realistic measure of central tendency.
