Answer:

<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>

Step-by-step explanation:

Let's find out the amount of cards that Math and Seth will have in week 20, using the information shown in the graph and table:

Amount of cards Seth has in week 20 = 20 * 4 = 80

The equation to find out the amount of cards, c, Seth has in week w:

c = 4w

Amount of cards Matt has in week 20 = 20 + (2 * 20) = 20 + 40 = 60

The equation to find out the amount of cards, c, Matt has in week w:

c = 20 + 2w

<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>

suter [353]

Answer:

The probability of the student incorrectly solves the next problem is 44%.

Step-by-step explanation:

Let E be the event of solving a problem correctly.

Then E' is the event that the problem is solved incorrectly.

Now, recall the definition of probability.

probability of an event = $\frac{number of favorable events}{total number of events}$

So,

p(E) = $\frac{40}{72}$

Also,

p(E) + p(E') = 1 and

p(E') = 1 - p(E)

= 1 - $\frac{40}{72}$

= $\frac{72-40}{72}$

= $\frac{32}{72}$

= $\frac{4}{9}$

= $\frac{4}{9} (100)$

= 44% rounded.

Hence, the probability of the student incorrectly solves the next problem is 44%.
