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:
Step-by-step explanation:

Yes
Square root of 4 times the square root of 3 is the square root of 12
The square root of 4 is a perfect square which is 2
2x4 is 8
The simplified answer is -8x the square root of 3
we have
1 donut -----> 570 calories
7 donuts ----> 600 calories
7 donuts ----> 510 calories
4 donuts ----> 480 calories
3 donuts ----> 400 calories
so
total donuts=1+7+7+4+3=22 donuts
the means is equal to
mean=(1*700+7*600+7*510+4*480+3*300)/22
mean=11,460/22
<h2>mean=521 calories</h2>
Part 2
Find out the median
order the data set from less to greater
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
the median is the middle of the data set
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
<h2>the median is 510 calories</h2>
