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
<u>A) contingency table </u>
attached below
<u>B) Determine the proportion of these lizards in this study that were either specie A or Specie B </u>
P ( A or B ) = ( 8 + 15 ) / 38 = 0.605 ≈ 0.61
<u>C) determine the probability that specie C lizard did not study </u>
P ( not surviving | C ) = 7 / 15 = 0.466 ≈ 0.47
Answer: X is equal to 30
Step-by-step explanation: I found this by taking 75 + 15 which is 90 then dividing it by 3 so 30. This is correct because since the linear pair is equal to 75 degrees then this also needs to be 75 degrees and 3 x 30 = 90 and 90 - 15 = 75.
Hope this helps.

e < 2
Answer:
8
Step-by-step explanation:
Let s represent the length of the shorter base and height. Then (3/2)s is the length of the longer base.
The area formula for a trapezoid is ...
A = 1/2(b1 +b2)h
Filling in the given values, we have ...
80 = (1/2)(s +3/2s)s = 5/4s²
64 = s² . . . . . . . . . . . . . . . . . . . multiply by 4/5
8 = s . . . . . . . . . . . . . . . . . . . . . take the square root
The length of the shorter side is 8.
Answer:
x =64.5
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
The total circle is 360 degrees
The arc is 360 - 113 - 118
arc =129
x = 1/2 (129)
x =64.5
