common difference, d = -3
f1 = -13
An arithmetic sequence f(n) = f1 + d(n - 1)
so f(n) = -13 - 3(n - 1)
f(46) = -13 - 3(46-1) = -13 -3(45) = -13 - 135 = -148
Answer:
f(46) = - 148
It's the first one because the other three go pasted -6 which would make the problem not true.
IT IS D!!!! i know because C stands for juice and your buying 2 of them and the 6 stands for the $6 for bagels, hope you get it right!
Answer:
range of scores on final exam student get B is 90 to 100
Step-by-step explanation:
given data
Psychology 101 score = 66
average of his midterm = between 78 and 90
maximum = 100 points
to find out
range of scores on final exam student get B
solution
we consider here lowest marks need in final = x
so average at two marks should be
equation is
average marks = 0.5 × ( mid term marks + final marks ) .................1
put here value
78 = 0.5 × ( 66 + x )
x = 90
and
90 = 0.5 × ( 66 + x )
x = 114
so range 90 to 114
but maximum marks is 100 so
range of scores on final exam student get B is 90 to 100
Answer:
440 miles
Step-by-step explanation:
Perimeter of a quadrilateral, P :
P = a + b + c + d
Which is the sum of all the sides ;
From the diagram attached ;
Perimeter of the quadrilateral is :
(170 + 160 + 80 + 30) = 440 miles
