Answer:
The answer to your question is three numbers
Step-by-step explanation:
Data
Numbers between 1 and 40
-Divisible by 2
-Prime numbers its digits.
Process
1.- Write all the numbers divisible by 2 between 1 and 40
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38
2.- Look for the numbers whose digits are prime numbers
2 22 32
3.- Conclusion
three numbers 2, 22 and 32
Substitute x-values into x.
e.g. y>-3.5x + 2
let x be 1...
thus, y>-3.5(1) + 2
y> -1.5 or y<1.5
another e.g. let x be 2.
y> -3.5(2) + 2
y> -4.4 or y<4.4
And so forth. pluck in these coordinates into you graph and sketch a line through the points.
NOTE: < in my explanation is equivalent to less than or equal to. same goes to >… greater than or equal to.
I hope you followed through. Good luck!
Answer: First Option -90° and 630°
Solution:
1) In clockwise the angle is negative, then is -90°
2) Counterclockwise the angle is positive and it could be:
270°
270°+360°=630°
Then, the answer is -90° and 630°
Answer:
The proportion of the variability seen in math achievement that can be predicted by math attitude is 0.78, the same value as the correlation coefficient.
Step-by-step explanation:
The correlation coefficient r between this two variables is found to be 0.78.
This coefficient can be calculated as:
where SSY' is the sum of the squares deviation from the mean for the predicted value and SSY is the sum of the squares deviation from the mean for the criterion variable.
Then, the value of the coefficient r is giving the proportion of the variability seen in the criterion value Y that can be explained by the predictor variable X.
