Answer:
Step-by-step explanation
if my answer is wrong i'm sorry here is a manual on how to do it if its wrong
i think they are right but just in case
Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
1 relation
2 function
3 relation
4 function
i know 4 is right but i don't know about others double check i suggest just in case i think they are right
The three remaining slices would form 108 degrees.
Hope this helped (and that I was right) =P
Answer:
Step-by-step explanation:
Data given
n=20 represent the sampel size
represent the sample mean for the independent variable (IQ score of the husband)
represent the sample mean for the dependent variable.
r =0.925 represent the correlation coefficient
Solution to the problem
The general expression for a linear model is given by:
Where 
is the intercept and 
the slope
For this case we have a linear model given by the following expression:
Where -3.34 is the intercept and 1.07 the slope. In order to find the best predicted value when X = 91 we just need to replace into the equation the value of 91 and we got this:
On this case is the best predicted value because 
we have an unbiased estimator.
Answer:
$7.96
Step-by-step explanation:
The equation 9.95/5=x would give you the price of one pound of grapes.
So, now that you have x, you would find out how much it costs if you bought 4 pounds.
4*x=7.96
(x = 1.99)
