[tex]2nx^{2} +15n+7\\[/tex]

Answers

Answer 1

Answer:

x = ± √(-15n-7) / √2n    (± (-15n-7)^(1/2) / (2n)^(1/2))

Step-by-step explanation:

Factoring?

2nx² + 15n+7 = 0

2nx² + 0*x + (15n+7) = 0  ... ax²+bx+c=0

Roots: x = (-2b ± √b²-4ac)) / 2a = (0 ± √0-4*2n*(15n+7)) / 4n

x = ± (√8n (-15n-7)) / 4n = ± (2√2n(-15n-7)) / 4n = ± (√2n(-15n-7)) / 2n

or x = ± √(-15n-7) / √2n

an event that has probability 1
is said to be

Answers

Answer:

guaranteed to occur

Step-by-step explanation:

An event that has a probability of 1 or in other terms P(E) = 1 is said to be guaranteed to occur. This is basically stating that the event has a 100% chance of happening, meaning that no matter what the external factors turn out to be in the scenario, the event will occur regardless. 1 basically represents 100%, while lower values such as 0.5 represent 50% when dealing with these probabilities.
