Answer:
mean =median, so the data is symmetrical
Step-by-step explanation:
Given
Data set= {10,5,8,10,12,6,8,10,15,6,12,18}
Mean= Sum of data points/number of data points
= (10+5+8+10+12+6+8+10+15+6+12+18)/12
=10
Median= mid value
={5,6,6,8,8,10,10,10,12,12,15,18}
Middle values are 10 and 10
Median = 10+10/2
= 20/2
= 10
Mean= median so there will be no skewness and the distribution is equal !
the answer is 22
i took the test
length = 15
breadth = 25
length = breadth + 10
let length be x
length = x
breadth = x + 10
perimeter = 2(length) + 2(breadth)
80 = 2(x) + 2(x + 10)
80 = 2x + 2x + 20
80 = 4x + 20
80 - 20 = 4x
60 = 4x
15 = x
length = x = 15
breadth = x + 10 = 25
Answer 10x + 6 is greater than or equal to 42.
Step-by-step explanation: The greater than or equal to symbol is not on here, but it’s > with a line underneath.
