Let the positive number be

The expression is

⇒ expanding the bracket gives,

⇒ rearranging to equate one side to zero

⇒ Dividing each term by 7 to simplify

⇒ Factorising gives


and

Hence, the first number is -5 and the second number is 3
According to the given, 1 in every 10 women has been a victim, therefore the probability of a victim of domestic abuse at some pint is

We need to use Binomial distribution to take a randomly sampled of 25 women and asked each whether she has been a victim.

Where x is the event that shows a victim of domestic abuse at some point.
We need to find the probability of these victim at least 2 has been victim of abuse, so
![P(x>=2) = 1- [P(x=0)+P(x=1)]](https://tex.z-dn.net/?f=P%28x%3E%3D2%29%20%3D%201-%20%5BP%28x%3D0%29%2BP%28x%3D1%29%5D)
![P(x>=2) = 1 - [^{25}C_0(0.10)^0(1-0.10)^{25-0}+^{25}C_1(0.10)^1(1-0.10)^{25-1}]](https://tex.z-dn.net/?f=P%28x%3E%3D2%29%20%3D%201%20-%20%5B%5E%7B25%7DC_0%280.10%29%5E0%281-0.10%29%5E%7B25-0%7D%2B%5E%7B25%7DC_1%280.10%29%5E1%281-0.10%29%5E%7B25-1%7D%5D)
![P(x>=2) = 1 - [0.07198+0.199]](https://tex.z-dn.net/?f=P%28x%3E%3D2%29%20%3D%201%20-%20%5B0.07198%2B0.199%5D)

So the probability is 0.729
The answer is 0.833333333
Answer: 450 yards
Step-by-step explanation:
From the question, we are informed that two blueberry farms are similar in shape and that the ratio of the side lengths of the farms is 4 : 5, and the smaller farm has a perimeter of 360 yards.
Since the smaller side which is denoted by 4 has a perimeter of 360, we divide 360 by 4 and then multiply the answer by 5 to get the perimeter of the larger blueberry farms. This will be:
= 360/4 × 5
= 90 × 5
= 450 yards
