The dot plot shows the number of classes per semester that a group of boys and girls have chosen to take in their freshman year of college. which statements correctly describe the two data sets? boys 0- 1- 3 boys 2- 7 boys 3- 6 boys 4- 2 boys 5- 1 boy 6- 1 boy girls 0- 1- 2 girls 2- 4 girls 3- 7 girls 4- 4 girls 5- 1 girl 6- 2 girls(choose all that apply) 1.) the difference of the means is 1.5. 2.)the difference of the means is 0.5. 3.)the difference of the means is about one-third the mean absolute deviation of either data set. 4.)the difference of the means is 1. 5)the difference of the means is about one-half the mean absolute deviation of either data set.

I is boy because the girls all less then boys

Step-by-step explanation:

because girls are leser than boys.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
