Step-by-step explanation:
and 4/2 = 2
Given:
A sum of money is divided between A,B and C in the ratio 9:8:7.
Total sum is 480.
To find:
The part of money A get.
Solution:
Let A, B and C get 9x, 8x and 7x respectively.
Total sum is 480.
Divide both sides by 24.
Now,
Therefore, amount received by A is 180.
Answer:
B. Yes, because P(X ≥ 68) ≤ .05
Step-by-step explanation:
The probability of a score X occuring is said to be unusually high if the probability of a score of X or larger is lower than 5%.
For each student, there are only two possible outcomes. Either they think that the court shows too much concern for criminals, or they do not think this. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
Three out of four students said that courts show too much concern for criminals. This means that
Would 68 be considered an unusually high number of students who feel that courts are partial to criminals?
We have to find .
So
is lower than 0.05, so this is an unusually high number.
So the correct answer is:
B. Yes, because P(X ≥ 68) ≤ .05
