Is 7,8,10 linear or non linear and why and pls don’t use big words cuz I don’t and then the teacher gonna ask why hahahah
Leona [35]

Answer:

9 and 8 are linear and 10 is non linear

Step-by-step explanation:

an = dn - c

The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.

For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:

an = 2n - 1.

Hitman42 [59]

Answer:

a)33.33333333%  b) 25%

Step-by-step explanation:

a) To find you're answer, you need to find the equivalent percentage to the fraction 4/12.  SO you need to do 4 divided by 12, or you can find an equivalent fraction. 4/12=1/3 and 1/3 is 33.33333%

b) The total number of fish is 4+12=16.  4/16= 1/4 and 1/4 is 25%

I really hope this answer helps!
