Answer:

In the year 2010

Step-by-step explanation:

we have

A=200e^{0.033t}

where

A is the population in thousands

t is the number of years since 1998

so

For A=297 thousands

substitute and solve for t

297=200e^{0.033t}

simplify

1.485=e^{0.033t}

Apply ln both sides

ln(1.485)=ln[e^{0.033t}]

ln(1.485)=(0.033t)ln(e)

Remember that

ln(e)=1

ln(1.485)=(0.033t)

t=\frac{ln(1.485)}{0.033}

t=12\ years

1998+12=2010

A restaurant serves a bowl of candies to their customers. The bowl of candies Gabriel receives has 10 chocolate candies, eight c
AVprozaik [17]

Answer:

3/10

Step-by-step explanation:

Let the total number of candies =

10 chocolate candies + 8 coffee candies + 12 caramel candies = 30 candies

Probability of picking a chocolate candy = P(chocolate) = 10/30

Probability of picking a coffee candy = P(chocolate) = 8/30

Hence, the probability of getting candies with P (chocolate or coffee)

= P(chocolate) + P(coffee)

= 10/30 + 8/30

= 18/30

= 3/10

Therefore, the probability of getting candies with P (chocolate or coffee) is 3/10
