Answer:
The probability that the student will not guess correctly on any one question is 4/5
Step-by-step explanation:
The question posed is an application of the binomial probability distribution.
We have been informed that the test has multiple choice questions with 5 choices for each answer that only one answer is correct for each question.
If the student guesses the answer to each question, then the probability that the student will guess correctly on any one question is 1/5.
Therefore, the probability that the student will not guess correctly on any one question is;
1 - 1/5 = 4/5
The answer is zero, when you multiply anything with zero, it always gives uou zero, no matter what the number or ewuation is.

When YZ and XW were identical,
Because the angles are all 180 degrees in either a triangle:
Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
Now when k =1.6 , y = 40 then x will be
Therefore the value of x is 25 when y =40.
