A solid line, because each lunch cost the same, and the price does not differ from lunch to lunch. So, 100 - 4 = 96  |  96 - 4 = 92, etc.

Answer:

The relationship will be a solid line.

Step-by-step explanation:

The relationship between the number of $4 lunches you buy with a $100 school lunch card and the money remaining on the card.

The relationship will be a solid line as it is a linear and common slope. Each time you buy lunch, the amount in the card will decrease by $4.

Let the number of lunches you buy be = x

Let the amount remaining in the card be = y

So, equation forms:

y=100-4x

When you buy 1 lunch, or x = 1

y=100-4(1)=96

When x = 2

y=100-4(2)=92

When x = 3

y=100-4(3)=88

We can see that the decrease is gradual and same.

You can also see the graph attached that a straight line is formed.

Montano1993 [528]

Answer:

P = 10/171

P = 0.058

The probability that both fish selected are Catfish is 0.0058

Step-by-step explanation:

Given:

The tank contains;

Algae eaters = 8

Catfish = 5

Tilapia fish = 6

Total number of fish = 8+5+6= 19

To determine the probability that both fish selected are Catfish P;

P = 5/19 × 4/18

( The number of the total number of fishes, and Catfish reduce by one after each selection because it is selected without replacement)

P = 10/171

P = 0.058
