Answer:
Step-by-step explanation:
In a square, each angle is 90.
11x - 32 = 90
Add 32 to both sides
11x = 90 +32
11x = 122
x = 122/11
x = 
The two digit number is 43.
If flipped around, the number is 34, which is 9 less than 43. 4 + 3 = 7.
Hope this helps!
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.
Answer:
B
Step-by-step explanation:
The answer is B because in order for the square root of a number to be equal to another number, the answer squared should be the number under the square root.
