The correct option is 1.
Step-by-step explanation:
It is given that the box plot shows the number of books sold each day at a store for 80 days.
A box plot is drawn with end points at 0 and 16. It means minimum value is 0 and maximum is 16.
The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.
He have to find the number of days in which the bookstore sell 2 to 12 books.
2 is first quartile and 12 is third quartile, we know that
The data lies between Q₁ and Q₃ is 50% of the data.
The bookstore sell 2 to 12 books in 40 days.
Therefore, the correct option is 1.
Answer:
A. (3,2)
Step-by-step explanation:
One way to solve without graphing
equate both equations to each other:
add x on both sides:
add 4 on both sides:
collect like terms:
divide 3 on both sides, so
now that we have x, go back to any one of the equations and substitute x=3 to find y. I'll use y=2x-4
sub x=3
2 × 3 is 6
we now have x and y, so the coordinates are (3,2)
If you want to use the graphing method, substitute in x values of your choice, for example -2 to 2 into each equation to find y and when there is a same coordinate in both equations that is the solution.
y = 2x - 4
when x is -2, y = 2(-2)-4 = -8. (-2,-8)
when x is -1, y = 2(-1) - 4= -6. (-1,-6)
when x is 0, y = 2(0)-4 = -4. (0,-4)
when x is 1, y = 2(1) - 4 = -2. (1,-2)
when x is 2, y = 2(2) - 4 = 0. (2,0)
when x is 3, y = 2(3) - 4 = 2. (3,2)
do the same thing of substituting to the other equation
y = -x + 5
when x is -2, y is 7 (-2,7)
when x is -1, y is 6. (-1,6)
when x is 0, y is 5. (0,5)
when x is 1, y is 4. (1,4)
when x is 2, y is 3. (2,3)
when x is 3, y is 2. (3,2)
plot these coordinates on a graph
they both have same x value (3) and same y value (2)
