1.23 123/100 123%
1.22 122/100 122%
How to Convert 123 to a Fraction
Result: 123/1 = 123
Step-by-step explanation:
Step-by-step explanation:
given
y is directly to x
to remove directly we use constant let constant be k
y=k x. (1)
let calculate value of k
as it is given
y=50 when x=5
so put in above equation (1)
50=k(5)
50/5=k
10=k
now let find y when x =11
in above equation put the value of x and k
y=10×11
y= 110
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.
