Answers
The required probability of that the person is of over 40 years of age. Option D is correct.
Given that,
If one of the 255 subjects is randomly selected, find the probability that the person is over 40 years of age is to be determined.
What is probability?
Probability can be defined as the ratio of favorable outcomes to the totalnumber of events.
Here,
Let the total number of people that has age of more than 40 years,
= 20 + 30 + 35
= 85
Now,
According to the question,
Probability is given as,
= 85 / 255
= 1/3
Thus, the required probability of that the person is of over 40 years of age. Option D is correct.

Answer:
1/3
Step-by-step explanation:
The number of people over 40 is 20 + 30 + 35 = 85.
So the probability is 85/255, which reduces to 1/3.

Step-by-step explanation:
As per the given scatter plot of voter turnout every year:
X axis represents the year and
Y axis represents the percentage of people who voted.
The model was predicted as per the equation:
To find:Prediction for the year 1900.
Putting the value of , the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.
So, the model predicts for the year 1900.

I always prefer quadratic formula as compared to factoring or completing the square to solve a quadratic equation.
What is a quadratic equation?
"A quadratic equation is an algebraic equation of the second degree in 'x'. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term."
In order to solve a quadratic equation, I always prefer quadratic formula as compared to the other methods.
In many cases, a quadratic equation can not be converted into a square or into factors.
Therefore, quadratic formula is the only method to solve all type of quadratic equation.
