Answer:
the solution of given rational equation is x= 3/2
Step-by-step explanation:
We need to solve the above rational equation and find value of x
Finding LCM of 4 and (2x-1) we get 4(2x-1).
Multiplying 4(2x-1) on both sides of equation and solving
So, the solution of given rational equation is x= 3/2
675 people will have score between 85 and 120
Step-by-step explanation:
Given
Mean = 100
SD = 15
If we have to find percentage of score between two values we have to find the z-score for both values and then area under the curve for both values
z-score is given by:
for a value x:
So,
For 85:
Now we have to find the area under the curve for both values of z-score. z-score tables are used for this purpose.
So,
For z1 : 0.1587
For z2: 0.9082
The area between z11 and z2:
So the probability of score between 85 and 120 is 0.7495
As the sample is of 900 people, the people with scores between 85 and 120 will be:
900*0.7495 = 674.55 people
Rounding off to nearest whole number
675 people will have score between 85 and 120

Hello,
Let's x² the square number
and 3*y the multiple of 3.
2 solutions : for (x,y) as integers : (-6,18) and (6,18)
but one solution for (x²,3y) as integers :<u> (36,54) </u>
