A school collected some information about the experience of its teachers. Here is what they found: Years of teaching experience Subject taught Less than 5 55 years 5 55 to 10 1010 years More than 10 1010 years Total Math 6 66 1 11 5 55 12 1212 Science 2 22 8 88 4 44 14 1414 Social studies 3 33 9 99 1 11 13 1313 English 4 44 9 99 2 22 15 1515 Other 7 77 16 1616 3 33 26 2626 Total 22 2222 43 4343 15 1515 80 8080 What fraction of English teachers have at least 5 55 years of experience?

anser is a

step-by-step explanation:

negitive slope

probability for j is 1/4

while

a is 1/6

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
