SOLUTION
Given the question in the image, the following are the solution steps to answer the question
STEP 1: Write the given details
STEP 2: Get the number of students that takes the subjects only
From the basic stuff, we have Number of candidates who had taken only each of the subjects
STEP 3: Represent the values above on a Venn Diagram after getting the values
STEP 4: Find the total number of candidate that sat for the exam.
Hence, the total number of candidates that sat for the exam is 276
Answer:
N=52
Step-by-step explanation:
13=n/4
13*4=n/4*4
52=n
X+127 = 180
x = 180 - 127
x =53
y + 74 = 180
y = 180 -74
y = 106
answer B.
x = 53, y = 106
Answer:
Step-by-step explanation:
In statistical hypothesis testing we use p values. For any test we select significance level alpha as 5% or 1% or 10%
Whenever p < alpha we reject our null hypothesis. Otherwise we accept our null hypothesis.
Hence p should be high to accept null hypothesis
Option A is incorrect
B is correct
C is wrong as p is the probability
D False
Option B is right.
C = 2πr
c/2π = 2πr/2π <--divide both sides by 2π
c/2π = r
r = c/2π <-- answer :)
