Formula for slope:
y₂: 6
y₁: 8
x₂: 1
x₁: -2
Plug them into the slope equation:
-->
--->
The slope is .
Firstly arrange the data pont from smaller to larger:
22------27--------46--------57------------73------------78---------------90
1st Q Median 3rd Q
Total Range : 90-22 = 68
Interquartile range: Q₃ - Q₁ = I = 78 -27 = 51
I hope the above is self explanatory
Step-by-step explanation:
am-an+bm-bn
m(a+b)-n(a+b)
(m-n)(a-b)
Answer:
adults=24
children=36
Step-by-step explanation:
x+y=60
400x+250y=18600
x=60-y
400(60-y)+250y=18600
y=36.
solve this expression then u will get the answer for y.
x+36=60
x=24.
