There are 3 Parts. Make sure to answer all 3 Parts. Read the problem and write your
Kryger [21]

Answer:

The answer is below

Step-by-step explanation:

The equation of a linear function is given as:

y = mx + b;

where y, x are variables, m is the rate of change and b is the initial value of variable y.

A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:

T = 25h + B

B) Given that B = 5, h = 6, hence:

T = 25(6) + 5 = 150 + 5 = 155 bacteria

C) The equation of the graph is:

T = 25h + 5

The graph was plotted using geogebra online graphing.

Four couples at a dinner party play a board game after the meal. They decide to play as teams of two and to select the teams ran
Llana [10]

Answer:

0.29

Step-by-step explanation:

We are given that there are 4 couples i.e. 8 people

They decide to play as teams of two and to select the teams randomly

Now we are asked How likely is it that every person will be teamed with someone other than the person he or she came to the party with

For people 1 , there are 6 options for pairing Since he or she cannot pair with his /her own partner

So, Choices For people 1 will be 6 person

So, Probability that person 1 will be teamed with someone other than the person he or she came to the party with = \frac{\text{No. of choices for Person 1}}{\text{Total no. of choices available}}=\frac{6}{7}

So,  Probability that every person (=8 person) will be teamed with someone other than the person he or she came to the party with =(\frac{6}{7})^8=0.29

Hence Probability that every person will be teamed with someone other than the person he or she came to the party with is 0.29
