The fuel consortium chairman at an airport recorded the
cost per barrel of crude oil and the cost per barrel of jet
fuel each week.
After plotting his results, the chairman noticed that the
relationship between the two variables was fairly linear,
so he used the data to calculate the following least
squares regression equation for predicting the cost, in
dollars, per barrel of jet fuel from the cost, in dollars, per
barrel of crude oil.
ŷ = 2+ = x
What is the residual of a week in which a barrel of
crude oil costs $60 and a barrel of jet fuel costs $78 ?

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

the correct answer is c
