If the number is between 25 and 35 It would have to be either 28 or 32.
Answer:
1st one
Step-by-step explanation:
Since the x's for each one are going up by the same number, you are looking for a column of y's to either by going up by the same number or down by the same number.
The first table has a column of y's that look like this: 1/2 , 1 , 1 1/2, 2
This is actually going up for 1/2 each time.
This table shows a linear function.
9x=5x+ (9=x)
(combine like terms)
9x=6x+9
(get the x value alone on one side of the equation, in this case by subtracting 6x from both sides)
3x=9
(divide by 3 on both sides to get x alone)
x=3
Answer: 0.263169
Step-by-step explanation:
Since for every child there is two outcomes (either a boy or a girl), so it is a binomial distribution.
Let x = Number of boys
Given: probability that a child is a boy: p= 0.513
Binomial distribution formula : 
Now, the probability that both children are boys= 
The chance both children are boys = 0.263169
