Question 1
Central High School is curious about how many ninth-grade students in the district participate in band, choir, and athletics. Based on previous years, the statics class came up with a model that shows 62% of ninth-grade students who participate in extracurricular activities will be in athletics. The data collected from this year is shown in the table.
School Name Band Choir Athletics Total. Valley high- 41,18,91,150 Central high 31,16,45,92 Logan high 27,12,64,103. Part A. identify the theoretical probability of participation in athletics, based on the model created by the statistics class. Then calculate the experimental probability that ninth graders will be in athletics for each of the three schools in the district? Part B
Compare the theoretical probablity from part A. In each instance, are they the same? if they are different, which one is higher? By how much do they differ?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

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.  

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
