Answer:
A
Step-by-step explanation:
none of the listed correlations make sense.
Answer:
The vector equation
The parametric equation
Step-by-step explanation:
Given
Required
The vector equation
First, we calculate the position vector of the point.
This is represented as:
The vector equation is then calculated as:
Open bracket
Collect like terms
Factorize
The parametric equation is represented as:
Where
By comparison:
Part A. 1 2/5 . or 1.4 because 5/10 = 1/2. 45/50 = 9/10. 1/2+9/10= 1 2/5 part B. no. explained in part a. part C. 9/10

Answer:
¼
Step-by-step explanation:
The probability of having a boy is ½ and that of a girl is ½.
Probability of boy, boy is (pb*pb) and given pb to be ½ then we can prove the point as follows
For these two children
The options are as follows
1 boy(first) and 1 girl
2 boys
2 girls
1 girl( first) and 1 boy
These are four possible options and the option for two boys is 1 out of the four.
The probability of 2 boys is ½*½=¼
