We have to find the graph where the mean of the flower heights is higher and the median is lower.
1st graph
M = ( 3 + 3 + 3 + 3 + 3 ) / 7
M = 15 / 7
Medium = 3
15 / 7 < 3 ( False )
2st graph
M = ( 2 + 6 + 2 + 1 + 1 + 3 ) / 6
M = 15 / 6
Medium = 4 / 2 = 2
15 / 6 > 2
So this is the requested chart.
Hope this helps, good studies.
Answer:
-3.2 or -1.5
** PS - with these problems literally just go to the website "mathpapa" it has an algebra calculator....ik the name is weird just go with it thank me later. **
x+(-2)>3
-2x>3 -3/2 or -1.5

-2 -2
Answer:
2, 4
Step-by-step explanation:
Let there are two unknown consecutive pairs of even integers 2n and 2n+2.
If the sum of the reciprocals of those two integers is 3/4, then we can write,
1/2n +1/(2n+2) =3/4 ...... (1)
Solving this above equation we can check whether the integers exist or not.
Now, from equation (1) we get,
1/n +1/(n+1) =3/2
⇒
⇒4n +2 =3n²+3n
⇒3n²-n-2 =0
⇒ (n-1)(3n+2) =0
⇒ (n-1) =0 {Since if (3n+2) =0 then, n will be a negative fraction, which is not possible}
⇒ n=1
∴ 2n =2 and 2n+2 =4
Hence, the two integers are 2, 4. (Answer)
