Answer:
2050
Step-by-step explanation:
<u>Year 2010</u>
The number of people over 65 years of age =32 million
Total population = 307 million.
P(meeting a person over 65 at random in 2010)
<u>Year 2050</u>
The number of people over 65 years of age =88 million
Total population = 434 million.
P(meeting a person over 65 at random in 2050)
Conclusion: Since 0.2028 is greater than 0.1042, the chances of meeting a person over 65 at random will be greater in 2050
Answer:
not congruent, they must have 3 equal sides and 3 equal angles. 72+38= 110, which means the last angle is 70°
The answer is 7, 24, 24.
The median is the middle number.
The mode is the number which occurs the most.
The range is the difference between the largest number and the smallest number.
Since 24 is the middle number, it is the median.
Since 24 is also the number which occurs the most often, it is also the mode.
To find range, do 24-7 which is equal to seventeen.

Answer:
m=2
Step-by-step explanation:
STEP 1 : m+0.6=2.6
move constant to the right-hand side and change it's sign m=2.6-0.6
STEP 1: m=2.6-0.6
subtract the numbers m=2
Answer:
- <u>Option C. The Network C sample.</u>
Explanation:
The variability of a sample may be described by using some common statistics like the variance and the standard deviation.
The variance and the standard deviation measure the difference between the values of the data and the mean. The variance is the average square of those differences or deviations. The standard deviation is the square root of the variance.
Thus, both variance and deviations, being an average of the differences of the data from the mean contain the number of data in the denominator of the equation.
That lets you know to conclude that the larger the number of data (the larger the sample) the smaller the variance and the standard deviation, this is the lower the variability of the data.
Hence, Network C, which has the greatest number of voters sampled (1,800) is likely to have the least variability.
