First on the left : 48+44=92
bottom left : (180-153)+(180-73)=134
mid top: 180-((180-143)+(180-71))=34
mid bottom :180-2(180-104)=28
top left : 180-(180-((180-95)+50))=135
bottom left :(180-(180-112)) divide by 2=56
DONE :)) is it correct tho? please tell me aft u mark it thanks :)

Researchers wanted to see which species of lizard (A, B, or C) is most likely to survive a bacterial infection. So they infected

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 certain coin is a circle with diameter 18 mm. What is the exact area of either face of the coin in terms of p?

vitfil [10]

Answer:

$r =\frac{D}{2}=\frac{18mm}{2}= 9mm$

The area is given by:

$A= \pi r^2$

And replacing we got:

$A=\pi (9mm)^2 =81\pi mm^2$

So then we can conclude that the area of the coin is $81\pi$ mm^2

Step-by-step explanation:

For this case we know that we have a coin with a diamter of $D =18mm$ , and by definition the radius is given by:

$r =\frac{D}{2}=\frac{18mm}{2}= 9mm$

The area is given by:

$A= \pi r^2$

And replacing we got:

$A=\pi (9mm)^2 =81\pi mm^2$

So then we can conclude that the area of the coin is $81\pi$ mm^2

Jenna manipulated the equation 4x + 7=10 by adding -7 to both sides.Which of the follolwing properties justifies this manipulati

elena-14-01-66 [18.8K]

The addition property of equality justifies this. You could also say that she simply subtracted 7, and then it would be the subtraction property of equality. This is the case because if you add or subtract (or multiply or divide) the same number on both sides of an equation, the equation will still be the same.

Hope it helps!

58.(A) (5pts)A certain type of bacteria, given favorable growth medium, quadruples in population every 6 hours. Given that there

Jet001 [13]

Answer:

157286400 bacteria

Step-by-step explanation:

We are given the following in the question:

The bacteria increases 4 times every 6 hours.

Initially there are 150 bacteria.

Thus, we can write the function for number of bacteria after x hours,

$f(x) = 150(4)^{\frac{x}{6}}$

We have to find the number of bacteria in 2.5 days.

1 day = 24 hours

Thus,

$2.5\text{ days} = 24\times 2.5 = 60\text{ hours}$

Putting x = 60 in the above equation, we get,

$f(60) = 150(4)^{\frac{60}{6}} = 150(4)^{10} = 157286400$

Thus, there will be 157286400 bacteria in two and a half days.
