Answer:
x = 48 and y = 104
Step-by-step explanation:
Given equations are:
From equation 1:
Putting the value of y in equation 2
Now we have to put the value of y in one of the equation to find the value of x
Putting y = 104 in the first equation
Hence,
The solution of the system of equations is x = 48 and y = 104
The value of variable which was assumed for number of hats, is the total number of hats.
Answer:
A
Step-by-step explanation:
is the standard deviation of x.
The standard deviation is gotten by:
1. find the average of x-values (add up all the values and divide by number of numbers, which is 5)
2. subtract the average, x bar, from each of the values, square it, and add up the difference
3. Divide that final answer by n, which is 5
4. Take the square root of the answer
<em>Now, let's find the average (x bar):</em>
<em>x bar = </em>
