1.) It seems that sequence just depends on adding 3 to get the next term.
The 25th term is 65
2.) a1 equals 12
first 4 terms are 12, 14, 16, 18
3.) Couldn't figure that one.
Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.
ANSWER
EXPLANATION
We want to solve the equation:
To do this, find the square root of both sides of the equation:
This will yield two results:
Solving the two equations, we have:
The solutions are:
What are you supposed to be solving for
318/2=159
159-74=85
the length is 85 yards
