Answer:
35 is 2 standard deviations BELOW the mean of 43
51 is 2 standard deviations ABOVE the mean of 43
find z - score for + 2 S.D. then subtract the z-score for - 2 S.D.
This is the percentage ( in decimal form) of 200 members between the ages of 35 and 51 Can you finish?
We can solve this by distributing
Now, distribute the 4 to both 8x and 5.
That's your answer!
Answer:
The equation has no solution; therefore, the system of equations has no solution
Step-by-step explanation:
we have
-----> equation A
-----> equation B
we know that
If after applying the linear combination method, Heather arrived at the equation 0 = 60
then
The reason is because both lines are parallel, therefore the system of equations has no solutions
<u>Verify</u>
isolate the variable y in the equation A
--------> the slope is 1/3
isolate the variable y in the equation B
--------> the slope is 1/3
Remember that
If the slopes are equal the lines are parallel
so
The system of equations has no solutions
