Use technology to determine the correlation coefficient, rounded to two decimal places, between the percentage of people in a country who are literate and the percentage who are undernourished. Use technology to find the equation of the regression line for the percentage who are literate and the percentage who are undernourished. Round "m" and "b" to two decimal places. Use technology to determine the percentage of people, to the nearest percent, can we anticipate are undernourished in a country where 60% of the people are literate?

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

what i would say the best answer is a. 40.5

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
