Slav-nsk [51]

Answer:

A) attached below

B) 0.61

C) 0.47

Step-by-step explanation:

Given data:

Total number of lizards infected = 38

Of the 15 species B lizards 40% survived

For specie C one more survived than died

Out of the 24 lizards that died 1/3 were species A

A) contingency table

attached below

B) Determine the proportion of these lizards in this study that were either specie A or Specie B

P ( A or B ) = ( 8 + 15 ) / 38 = 0.605 ≈ 0.61

C) determine the probability that specie C lizard did not study

P ( not surviving | C ) = 7 / 15 = 0.466 ≈ 0.47

A. 207.5ft

Law of cosines:

a^2 = b^2 + c^2 -2 *b*c*coa(a)

a^2 = 60.5^2 + 257^2 - 2*60.5*257*cos(31)

a^2 = 3660.25 + 66049 - 2 *60.5 * 257 * 0.857167

a^2 = 3660.25 + 66049 - 26655.33

a^2 = 43053.92

a = SQRT(43053.92)

a = 207.49 = 207.5 feet.

The answer is A.
