Answer:
In this scenario you should use chefs if you have less than 55 people and you should use cece's if you have more than 55 people.
Step-by-step explanation:
To find out which one will be cheaper you need to know where they intersect, to do this you need to set up a system of equations.
y=28x+590 (chefs)
y=31x+425 (cece's)
to know where they intersect you need to make the y=0
28x+590=31x+425
Then solve
subtract the x from each side
590=3x+425
Subtract 425 from each side
3x=165
divide each side by three
x=55
now evaluate
Place a number above 55 (60 for example) into the place of x
28(60)+590=2,270
31(60)+425=2,285
In this scenario you should use chefs if you have less than 55 people and you should use cece's if you have more than 55 people.
<span>In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it. For this we get: 6724, 2209, 10404, 11664, 729, 1764, 12544, 9, 529, 71824, 1444, 1024. Now we sum all of these up and take the average by dividing the sum by 12. Doing this we get 120868/12=10072. The last step is the take the square root of that number to get the standard deviation. The final result is 100.</span>
Answer:
4,000
Step-by-step explanation:
You go to the thousand number and see if the hundred number is higher than 5, if not then its stays the same.
The answer to this question using the quadratic formula is x= -1+3√5/2 and x=-1-3<span>√5/2
</span>that is a square root, or, 3 times the square root of 5 ALL over 2, except for the 1. Same with the other one.
