The box plots show data about the number of years that farmworkers have been employed at each of two farms
Answers
Answer:
The third quartile of the data for Farm Y is less than the third quartile of the data for Farm X.
Step-by-step explanation:
The correct option is the median for the data of farm Y is greater than the farm X.
What is a box plot?A box plot is a method for graphically demonstrating the locality, spread and skewness of groups of numerical data through their quartiles.
Given that, a box plots show data about the number of years that farmworkers have been employed at each of two farms
Range for farm X = 35-16 = 19
Range for farm Y = 30-15 = 15
Therefore, the range of X is greater than Y and not equal.
Third quartile for Y = 27
Third quartile for X = 24
That mean, q3 X < q3 Y
First quartile for Y = 12
First quartile for X = 17
That mean, q1 X > q1 Y
Median of X = 17
Median of Y = 18
Therefore,
M X < MY
Hence, the correct option is the median for the data of farm Y is greater than the farm X.

Answers
Answer:
The answers of all four questions are below.
Step-by-step explanation:
(5)4+2x=−2x+44
Step 1: Simplify both sides of the equation.
2x+4=−2x+44
Step 2: Add 2x to both sides.
2x+4+2x=−2x+44+2x
4x+4=44
Step 3: Subtract 4 from both sides.
4x+4−4=44−4
4x=40
Step 4: Divide both sides by 4.
4x/4=40/4
x=10
-----------------------------------------------------------------------------------------------------------------
(6)114−3x=194−11x
Step 1: Simplify both sides of the equation.
114−3x=194−11x
114+−3x=194+−11x
−3x+114=−11x+194
Step 2: Add 11x to both sides.
−3x+114+11x=−11x+194+11x
8x+114=194
Step 3: Subtract 114 from both sides.
8x+114−114=194−114
8x=80
Step 4: Divide both sides by 8.
8x/8 = 80/8
x=10
------------------------------------------------------------------------------------------------------
(7)4x-12=-2x+36
4x-12+12=-2x+36+12
4x=-2x+48
4x+2x=-2x+48+2x
6x=48
6x/6=48/6
x=8
-----------------------------------------------------------------------------------------------------------
(9)-3x+90=117-12x
-3x+90-90=117-12x-90
-3x=-12x+27
-3x+12x=-12x+27+12x
9x=27
9x/9=27/9

Answers
area of rectangle is length x width
3x2=6
12x7=84
add them together
6+6+84=96
Answer:
90 cm^2
Step-by-step explanation:
So we can split the figure to two rectangles and a square
The first and last rectangle have the same area,
The area of the first rectangle = 9 * 3
= 27 cm^2
The area of the square = 6 * 6
= 36 cm^2
So the total area of the figure is,
(27+27) + 36 = 54 + 36 = 90cm^2

Number 1
For triangle
A=1/2bh
A=1/2*3*4
A=1/2*12
A=6
Find the area of the circle
Diameter is twice a radius so the radius would be 2
