Answer:
1,005.84 cm
Step-by-step explanation:
Given the unit fractions, 36 in/1 yd (i.e. 36 inches = 1 yard), and 2.54 cm/1 in (i.e. 2.54 cm = 1 inches), to convert 11 yd to cm, first convert to inches, then convert what you have in inches to cm.
Thus:
Converting 11 yd to inches:
36 in = 1 yd
11 yd = 36*11 = 396 in
Converting 396 in to cm:
2.54 cm = 1 in
396 in = 2.54*396 = 1,005.84 cm
Hello,
We can set up two equations and solve the problem.
Let x be Crocus and y be daffodil. So:
x+y=40
.45x+.65y=20.40
Multiply the first equation by -.45 so to eliminate x. So we get:
-.45x-.45y=-18 Now add this to the second equation:
+.45x+.65y=20.40
And we get:
.20y=2.40 Divide each side by .25 to get:
y=12 Now we can find x by plugging 12 for y in the first equation:
x+12=40 Subtract 12 from both sides to get:
x=28
So now we know there are 12 daffodil and 28 crocus.

Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Correlation Coefficient (r) = 0.989
alph=0.05
Number of observations (n) = 8
determine if there is a linear correlation between chest size and weight.
Yes, there exists a linear relationship between chest size and weight as the value of the correlation Coefficient exceeds the critical value.
What proportion of the variation in weight can be explained by the linear relationship between weight and chest size?
To determine the the proportion of variation in weight that can be explained by the linear regression line between weight and chest size, we need to obtain the Coefficient of determination(r^2) of the model.
r^2 = square of the correlation Coefficient
r^2 = 0.989^2 = 0.978121
Hence, about 0.978 (97.8%) of the variation in weight can be explained by the linear relationship between weight and chest size.
