The square root is
Just square the top and bottom of the fraction.
and
so we have 12/16 and then we reduce to 3/4
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.
Your hypothesis is correct because you substitute 1 to x then add which gives you an answer

Answer:
x^2 -25 = (x+5) (x-5)
Step-by-step explanation:
X^2-25
This is the difference of squares
a^2 -b^2 = (a+b) (a-b)
a^2 = x^2 so a=x
b^2 = 25 so b=5
x^2 -25 = (x+5) (x-5)
