4. You estimate a model with 5 explanatory variables and an intercept from a data set with 247 observations. To test hypotheses on a single coefficient LaTeX: \betaβ3 in this model you should use a t distribution with how many degrees of freedom? a.) 242 b.) 120 c.) [infinity] d.) 241

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
