Answer:
<h3>The answer is option A</h3>Step-by-step explanation:
Since the figure above is a right angled triangle we can use trigonometric ratios to find GV
To find GV we use cosine
cos∅ = adjacent / hypotenuse
From the question
GV is the adjacent
GC is the hypotenuse
So we have
<h3>GC = 55°
<h3 /><h3>GV</h3><h3>GV = 55 cos 37
GV = 43.92495
We have the final answer as
<h3>GV = 43.92</h3>Hope this helps you
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: A
Step-by-step explanation:
A is false. Not all reals numbers are rational numbers. Some real numbers can contain irrational numbers, like . This is a real number, but isn't rational since it cannot be represented as a ratio.
