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

The equation below describes a proportional relationship between x and y. What is the constant of proportionality? 2 у= 5Х.
Answer:Hello, my name is woods245 and I'm here to help you with your problem K?
So the equation that you have is 2y=5X.
So what you will have to is put a line under 2y and 5X.
Then you mark out 2y and divide 5X and 2y and get 2.5 that's your answer.

Answer:
x = 36
1 = 42
2 = 108
Step-by-step explanation:
2x + x + 72 = 180
3x + 72 = 180
-72 -72
3x = 108
divide by 3
x = 36
_______________________
1 = 2x
1 = 2(36)
1 = 42
_______________________
2 = x + 72
2 = 36 + 72
2 = 108

The pitchers that Isaac bought for the party each hold 2 quarts of liquid. If he makes 15 pints of smoothie and has three pitchers, how much of the smoothie will not fit into the pitchers?

an event that has probability 1
is said to be
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.
