Predicting Calories Consumed Using the data in NutrtitionStudy, we show computer output for a model to predict calories consumed in a day based on fat grams consumed in a day, cholesterol consumed in mg per day, and age in years: The regression equation is Predictor Coef SE Coef T P Constant 512.95 86.51 5.93 0.000 Fat 16.2645 0.7925 20.52 0.000 Cholesterol 0.4208 0.2015 2.09 0.038 Age -1.420 1.304 -1.09 0.277 Analysis of Variance Source DF SS MS F P Regression 3 111082085 37027362 336.12 0.000 Residual Error 311 34259921 110161 Total 314 145342006 Click here for the dataset associated with this question. (a) What daily calorie consumption does the model predict for a 30 year old person who eats 47 grams of fat in a day and 182 mg of cholesterol?
(b) In this model, which variable is least significant? Which is most significant?
(c) which predictors are significant at a 5% level?
(d) Interpret the coefficient of Fat in context.
(e) Interpret the coefficient of Age in context.
(f) Interpret what the ANOVA output says about the effectiveness of this model.
(g) Interpret R2 for this model.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

he answer is x=1x3 because x=1 to x=3

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
