Atrend forecast equation is being developed to describe sales over time. the analyst has completed the tabulation using the raw data and is about to develop the forecast equation with the least squares equations. use the calculated trend information tabled below to calculate the simple linear regression equation (hint: for y = a + bx, find the values of a and b). number of periods, n = 5 ybar = 5 xbar = 3 sum ( x2 ) = 55 sum ( xy ) = 80 the calculated linear regression equation is:

A.)complete this table by reading the values from the graph. estimate any function values that are less than one. x -3 -2 -1 0 1 2 3 exponential function linear function b.)at approximately what values of x do both the linear and exponential functions have the same value for y?

Find the surface area of a square pyramid with side lengths 6yd and slant height 6yd

Check and edit for me! it's not super long ; )it was one long hour. she exhaled, eyeing the brown clock vigilantly. one more hour of total boredom and suffering. her afterschool activity had been repealed last minute, so she had to wait to be picked up instead. she sat on a dirty peeling maroon bench in the schoolyard. her back to the worn soccer pitch, she started to doodle on her orange and blue notebook. might as well find some way to pass the time. as you write and revise, ask yourself these questions: 1. do all of the sentences in this paragraph belong here? (unity)2. are all of the sentences in this paragraph in the right place? (coherence--method of development)3. are all of the sentences in this paragraph smoothly connected together into a whole paragraph? (coherence--use of transitional devices)once you've made certain that your paragraphs are both unified and coherent, edit your work for problems in grammar and mechanics before submitting it to your teacher.
