Answer:
33/338
Step-by-step explanation:
Green = 11
Red = 6
Blue = 9
P.Red = 6/26 = 3/13
P.Green = 11/26
P. Both in turns = 3/13 * 11/26
= 33/338
<u>Given</u>:
Mean,

Standard deviation,

The Chebyshev theorem will be used for the solution of the given query,
i.e., 
(i)
⇒ 

The lower limit will be:
= 
= 
= 
The upper limit will be:
= 
= 
= 
hence,
The 75% houses sold are between:
⇒ (200000, 400000)
(ii)
⇒ 
By putting the values, we get





now,
⇒ 


(%)
hence,
88.88% houses sold between 150000 and 450000.
(iii)
⇒ 
By putting the values, we get





now,
⇒ 

(%)
hence,
85.21% houses are sold between 170000 and 430000.

Answer:
x=-1
Step-by-step explanation:
2x+6=3-x
Step 1: Simplify both sides of the equation.
2x+6=3−x
2x+6=3+(−x)
2x+6=−x+3
Step 2: Add x to both sides.
2x+6+x=−x+3+x
3x+6=3
Step 3: Subtract 6 from both sides.
3x+6−6=3−6
3x=−3
Step 4: Divide both sides by 3.
3x/3=−3/3
x=−1
Answer:
x=−1

Step-by-step explanation:
Answer:
Interquartile Range = 34
Range = 55
Step-by-step explanation:
Max - Min = Range
75 - 20 = 55
Quartile 3 - Quartile 1 = IQR
68 - 34 = 34
