Step-by-step explanation:
x° + 61°+ 68° + 104° = 180°
x° + 129°+104°=180°
x°+133°=180°
x°=180°-133°
x=47°
Since we can't use a zero at the start and end, then we have 810 different ways.
If we can't have a leading digit of zero, then we still have 9 available digits to choose from (9P1)
Now, the second term can be of any number, so we will have 10 different digits to choose 1 (10P1)
Now, the final term cannot be a zero, so we will have 9 available digits to choose from (9P1)
Hence, our final number of ways is: 9 × 10 × 9 = 810 ways.
Answer:
wow
Step-by-step explanation:
Answer:
And for this case
The % of variation is given by the determination coefficient given by and on this case , so then the % of variation explained is 20.25%.
The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.
Step-by-step explanation:
For this case we asume that we fit a linear model:
Where y represent the final grade and x the math ability scores
Where:
And we can find the intercept using this:
The correlation coeffcient is given by:
And for this case
The % of variation is given by the determination coefficient given by and on this case , so then the % of variation explained is 20.25%.
The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.
