A + c = 186.....a = 186 - c
9.60a + 5.70c = 1399.50
9.60(186 - c) + 5.70c = 1399.50
1785.60 - 9.60c + 5.70c = 1399.50
-9.60c + 5.70c = 1399.50 - 1785.60
-3.90c = - 386.10
c = 386.10 / 3.90
c = 99....so there were 99 child tickets sold
Answer:
a and b
if im not correct im sorry.
Answer:
a = -1
b = -9
c = 9
d = 3
e = 3
f = 2
g = 3/2
Step-by-step explanation:
* Lets explain how to solve the problem
∵
are rational fractions
- To add or subtract the rational fractions they must have same
denominator
∵ 6 - 2x must be written 2x - 6, take (-1) as a common factor from 6 - 2x
∴ - 1(-6 + 2x) = - 1(2x - 6)
∴ 
∴ a = -1
∵ 9 ÷ -1 = -9
∴ = 
∴ b = -9
∵ The denominators of the two fractions are 2x - 6
∴ We can add them by adding their numerator
∵ 3x + -9 = 3x - 9
∴ = 
∴ c = 9
∵ 3x - 9 has a common factor 3
∴ 3x - 9 = 3(x - 3)
∵ 2x - 6 has common factor 2
∴ 2x - 6 = 2(x - 3)
∴ = 
∴ d = 3 , e = 3 , f = 2
- The fraction has same factor (x - 3) up and down then we can cancel
them together
∴ = 
∴ g = 3/2
You need to include the image of the question it doesn’t make sense if
Answer:
The probability of success is 1/2.
Step-by-step explanation:
The histogram of a binomial distribution has a mode of n×p. For that to be n/2, the value of p must be 1/2.
