The negative number would most likely be -19/2
let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation
2x^2-3x=209
2x^2-3x-209=0
hence using quadratic eqn
x=11 ( rej since qn stated x is a negative number)
x=-19/2

Answer: 2/3</h3>
Here are the outcomes that are less than five = {1, 2, 3, 4}. There are A = 4 values here.
Here are all the outcomes possible: {1, 2, 3, 4, 5, 6}. There are B = 6 ways to roll a single number cube (aka dice).
Divide the two values: A/B = 4/6 = (2*2)/(2*3) = 2/3
The fraction 2/3 is approximately equal to 0.667 which converts to 66.7%
You are performing a hypothesis test. You have a null hypothesis and an alternate hypothesis. If the test result is not significant, you accept the null hypothesis and reject the alternate hypothesis. That does not mean that you KNOW which hypothesis is true.

Answer:
9.68*10^-10
Step-by-step explanation:
The problem above can be solved using the binomial probability relation :
Where ;
P(x = x) = nCx * p^x * q^(n-x)
n = number of trials = 25
p = 1/4 = 0.25
q = 1 - p = 0.75
x = 20
P(x > 20) = p(x = 21) + p(x = 22) +.. + p(x = 25)
Using the binomial probability calculator to save computation time :
P(x > 20) = 9.68*10^-10
