d) speed of growth

e) P(t) = 7/2 t

P = height

t = time in weeks

f) P(9) = 7/2 (9) = 63/2 = 31.5 ft

Answer:

C. Children have much greater chance of having side effects than adults.

Step-by-step explanation:

It is known that the conditional probability for two events A and B is given by,

P(A|B)=\frac{P(A\cap B)}{P(B)}.

Then, according to the table, we have,

P(sideeffects|child)=\frac{P(sideeffects\cap child)}{P(child)}

i.e.  P(sideeffects|child)=\frac{20}{50}

i.e.  P(sideeffects|child)=0.40

Moreover,

P(sideeffects|adult)=\frac{P(sideeffects\cap adult)}{P(adult)}

i.e.  P(sideeffects|adult)=\frac{6}{50}

i.e.  P(sideeffects|adult)=0.12

As 0.40 > 0.12.

Children have more chances of having side effects than adults.

Hence, option C is correct.

If B is the midpoint of AC, and AC=8x-20. Find BC<br> AB=3x-1<br> Show all work
exis [7]
First we know that:
AB+BC=AC
now , since B is the midpoint of AC, this means that AB=BC
therefore,
AB+BC=AC can also be written as
AB+AB=AC
3x-1+3x-1=8x-20
6x-2=8x-20
-2+20=8x-6x
18=2x
x=9

therefore:
AB=3(9)-1=27-1=26
AC=8(9)-20=52
BC=AB=26
