Answer:

It is linear

Step-by-step explanation:

Due to the pattern in the table the common difference it always 4. For example, 18-14=4 .    14-10=4 and so on.

Here the difference between two consecutive x terms =14-18=-4

And we have to use the following formula

f(x) = a + (x-1)d

Substituting the values of first term, a common deifference,d, we will get

f(x) = 18+(x-1)(-4)

f(x) = 18 -4x+4

f(x) = 22-4x

So the required model for the given table is f(x) = 22-4x .

Help me fast I need please
ale4655 [162]

Answer:

2/9

Step-by-step explanation:

Since there are 18 total eggs (cracked, white, brown) we can say that the denominator will be 18.

There are 8 white eggs, and when half of those are cracked there will be 4 uncracked and 4 cracked, so 4/18.

Simplify 4/18 to 2/9 and there is your answer.
