Let's assume
rent of the one chair = x
rent of the one table = y
3x + 2y = 24
8x + 4y = 53
multiply the first equation by 2
6x + 4y = 48
8x + 4y = 53
if we subtract from last equation to previous equation,
2x = 5
x = 2.5
y = 8.25
Therefore the cost of one chair is 2.5 dollars
the cost of one table is 8.25 dollars
That would mean the week before there were 120 students, so you have to add 120 and 103 to get how many there were absent in those two weeks which would be 123
Answer:
C. The fill weight is less than 910 grams.
Step-by-step explanation:
To normalize a given stadistical we do:
![\frac{X - \mu }{\sigma} \\Where:\\X = $ the weight of the cereal box\\\mu = $ the mean of 910 grams\\\sigma = $ the standard deviation](https://tex.z-dn.net/?f=%5Cfrac%7BX%20-%20%5Cmu%20%7D%7B%5Csigma%7D%20%5C%5CWhere%3A%5C%5CX%20%3D%20%24%20the%20weight%20of%20the%20cereal%20box%5C%5C%5Cmu%20%3D%20%24%20the%20mean%20of%20910%20grams%5C%5C%5Csigma%20%3D%20%24%20the%20standard%20deviation)
To be negative then, X should be lower than the mean.
Therefore, is the nevatige value of Z represent the value is below the mean therefore, below 910 gram
