Answer:
, which is the third function listed among the possible answers.
Step-by-step explanation:
Notice that these are all exponential functions, that contain just "x" in the exponent, and one "1' as the accompanying coefficient. So, in order to decide which ones are increasing, we need to study the base of the expression with exponent "x".
If the base is a number smaller than one, the function is decreasing.
If the base is a number larger than one, the exponential function is increasing.
Therefore, the only one that shows a larger than one base is the third one :
which is therefore the only increasing function of the group.
The nearest ten thousand to 16,500 is 20,000. So it is rounded up to 20,000.
Because 16,500 is more nearest to 20,000 than 10,000, a the second digit after 1 is 6 which is greater than 5 and close to 10 than 1. if it is less than 5, for example if the number is 14,500 then the number will be rounded to 10,000 as that one is more closest than 20,000.
But here 16,500 is rounded to 20,000.

Answer: D) 57
Step-by-step explanation:
Answer:
5.47% of the total variation between the two variables can be explained by the regression line.
Step-by-step explanation:
Given :
R value = 0.234
The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.
However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².
R² value is Obtained by taking the squared of the correlation Coefficient
Hence,
R² = 0.234² = 0.054756
R² = 0.05476 * 100% = 5.4756%
Hence, R² = 5.48%
This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.
