According to dolbear’s law, you can predict the temperature t (in degrees fahrenheit) by counting the number x of chirps made by a snowy tree cricket in 1 minute. for each rise in temperature of 0.25°f, the cricket makes an additional chirp each minute. a. a cricket chirps 40 times in 1 minute when the temperature is 50°f. write an equation in slope-intercept form that represents the temperature in terms of the number of chirps in 1 minute.

100 points, hi, i’m not sure what to do here, the data doesn’t seem to be quadratic .? can anyone me, in advance

What is the range of the function? f(x)=-2|x+1|? a. all real numbers. b. all real numbers less than or equal to 0. c. all real numbers less than or equal to 1. d. all real numbers greater than or equal to 1

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
