Answer:
n = 200
p = 0.33.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this problem we have that:
33% of the births are Cesarean, so 
Sample of 200 births, which eans that, 
Answer: The equation is $29 + x*$4.50 = $42.50, and the solution is x = 3
Step-by-step explanation:
The data we have is:
Gonzales has $42.50
He wants to buy:
a shirt that costs $29
some bracelets that cost $4.50 each.
The equation that we need to solve is:
Total cost = money that Gonzales has.
The cost is $29 + x*$4.50
where x is the number of bracelets he can buy.
The equation that we need to solve is:
$29 + x*$4.50 = $42.50
to solve it we must isolate x:
x*$4.50 = $42.50 - $29 = $13.50
x = 13.50/4.50 = 3
So we have that Mr. Gonzales can buy a total of 3 bracelets.
Step-by-step explanation:
You can choose one of the prices above to find the proportion.

Answer:
HOPE THAT MAY HELP YOU :)
Step-by-step explanation:
Equal groups are illustrations of using the same variable.
A word problem that uses equal group is:
Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled
The only condition for equal groups is that:
The units or variable must be the same
For instance:
Add 5 miles and 4 miles ----- This represents distance
Remove 2 liters from 7 liters --- This represents volume
Add 5 hours and quarter of an hour -- This represents time
And so on.
