Zekes family has more children. Because of when they say 2/3. it basicly tells u. that Sonia's family has less children. since it's not equal or greater then Zekes.
Answer:
<h2>B. cannot be determined</h2>
Step-by-step explanation:
For two events A and B to be independent, it means they can occur at the same time i.e the occurrence of one does not affect the other occurring. It is represented as P(A∩B) = P(A)P(B)
Given P( A) = 0.60 and P( A| B) = 0.60, to find P(B), we will use the formula for the conditional probability P( A| B) = P(A∩B) /P(B)
P( A| B) = P(A)P(B) /P(B)
P( A| B) = P(A)
Since P( A| B) = 0.60, therefore P(A) is also equal to 0.60 and P(B) cannot be determined since they cancelled out already
The correlation coefficient measures the relationship between the two variables
The correlation coefficient is 0.234
<h3>How to determine the correlation coefficient</h3>
The formula of correlation coefficient is:
Using the dataset from the complete question, we have:
Evaluate the difference
Evaluate the quotient
Approximate
Hence, the correlation coefficient is 0.234

Answer:
Third option
Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (-1, 5)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (-1, 5), the equation sought is:
Therefore the answer is the Third option.
