Answer:
answer is in the attached picture
Step-by-step explanation:
To construct the box-and-whisker plot from the given data we first need to find the 3rd quartile.
To find the 3rd quartile we will use the interquartile range and 1st quartile.
Interquartile range = 3rd quartile - 1st quartile
(substitute the values given in the question)
3 = 3rd quartile - 6
3rd quartile = 3 + 6
3rd quartile = 9
hence we now have the complete data to construct the box-and-whiskers plot.
The plot is in the attached picture.
Answer:
127.3
Step-by-step explanation:
T≈127.333≈127.3
∘
Answer:The answer is c
Step-by-step explanation:
Multiply both side is the equation by -1.
Sum the equations vertically to eliminate at least one variable
Divide both sides of the equation by 3
Substitute the given value of y into the equation 2x+3y=8
and then solve for x
X=70 because you have to convert the decimals to fractions so that the .35 equals 7/20 and .45 equals 9/20 then simplify the complex fractions on each side so 7/20 over 2X/3 equals 21/40X and the 9/20 over the X-10 equals 9/20(X-10), then cross multiply to get 420 (X-10)= 320X, next you would distribute the 420 through the parenthesis to get 420X-4200=360X, then add 4200 to both sides so 420X on its own then add 360X on both sides so both X's are on the same side then combine like terms and get 60X on the left, then divide both sides by 60 so X is on its own so X=70
