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
Plug in 35 into the equation P(t)
P(35) = 14(35)^2+650(35)+32,000
Answer:
Step-by-step explanation:
Given :
- The length of a rectangle is 4m more than the width.
- The area of the rectangle is 45m²
⠀
To Find :
- The length and width of the rectangle.
⠀
Solution :
We know that,

So,
Let's assume the length of the rectangle as x and the width will be (x – 4).
⠀
Now, Substituting the given values in the formula :







⠀
Since, The length can't be negative, so the length will be 9 which is positive.
⠀
