Solving this problem requires the supplement of the actual expression. However I believe you forgot to include it with the question.

However I believe that the expression is in the form of:

y = A e^(-k t)

where,

y is the number of bacteria after time t

A is a constant and represents the initial number of bacteria

k is the growth rate in decimal form

t is time

<span>So whatever is located in A is the initial number of bacteria, while k times 100% is the growth rate.</span>

9) HH, HT, TT, TH: 1/4

Step-by-step explanation:

O - Not certain, it is possible to choose a green marble

O - Certain, all the numbers in the bag are less than 100, so the one you choose must be less than 105

O - Not certain, the spinner will not always land on the 10th letter of the alphabet

Small cup, Mint chocolate, Sprinkles

Small cup, Mint chocolate, Caramel sauce

There are 9 options with a small cup

There are 4 possibilities for types of cups

Multiply

4 * 9

The question is asking what would the sample space be of flipping a coin 2 times. You will not always alternate (heads, tails, heads, tails) when flipping a coin. This means that all of the possibilities are HH, HT, TT, TH.

Chance of getting heads = 1/2

Chance of getting tails = 1/2

Chance of getting 2 heads (divide by 2) = 1/4

Chance of getting 2 tails = 1/4

HH, HT, TT, TH: 1/4
