Answer:
it is not a prim number because ONE is not greater than ONE and it is not composite because in that case you can not multiply or divide one by its self
Step-by-step explanation:
in order for a number to be prim you have to have it only be able to be multiplied by one to get the answer but it has to be greater than one. in order for a number to be composite it has to have at least one divisor other than one its self

Answer:
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288

Answer:
13/15
Step-by-step explanation:
I assume you mean the ratio 4/5 : 12/13
Ratio means division, so it's 4/5 / 12/13
Multiply by reciprocal: 4/5 * 13/12 = 13/15
