Answer:
212 children, and 265 adults
Step-by-step explanation:
To find the number of children and adults, we can set up a systems of equations.
x= number of children
y= number of adults
Equation 1: Price
1.50x+2.25y=914.25
Equation 2: Total number of people
x+y=477
Now, let's solve the equation using substitution.
Rearrange the second equation to solve for one variable.
x+y=477
x=477-y
Now plug x equals into the first equation, and solve for y.
1.50x+2.25y=914.25
1.50(477-y)+2.25y=914.25
715.5-1.50y+2.25y=914.25
715.5+0.75y=914.25
0.75y=198.75
y=265
We just solved for the number of adults. Now let's plug y equals into the second equation to find the number of children.
x+y=477
x+265=477
x=212
So I am pretty sure that inverse means reason.
example:
2+4=6
Basically, any two even numbers together make an even number
230/10 = 23 with no remainder.
236/10 = 23 with remainder 6.
6 crayons were left over.
Answer:
yes 613 is odd

Answer:
11.04
Step-by-step explanation:
Given the data:
29, 15, 22, 52, 38
The mean absolute deviation :
Mean, m = Σx / n
n = sample size = 5
29 + 15 + 22 + 52 + 38 = 156
Mean = 156 / 5 = 31.2
Mean absolute deviation (MAD):
Σ|x - m| / n
(|29 - 31.2| + |15 - 31.2| + |22 - 31.2| + |52 - 31.2| + |38 - 31.2|) / 5
(2.2 + 16.2 + 9.2 + 20.8 + 6.8) / 5
55.2 / 5
= 11.04
