Answer:
q=12
Step-by-step explanation:
-11=61-6q
-11-61 =-6q
-72=-6q
q=72/6
q=12
To solve this, you know that both values listed (4x - 3 and -3x + 4) are equal to y, so you know that they also must be equal to each other! Therefore you can form the following equation:
4x - 3 = -3x + 4
Now you can add -3x to both sides to combine like terms:
7x - 3 = 4
Now add 3 to both sides:
7x = 7
Now if you divide everything by seven, you see that x = 1. Now that we have out x value, we can go ahead and plug it into one of the equations. This gives us:
y = 4(1) - 3
If we multiply out, we get:
y = 4 - 3
y = 1
So y also equals 1! Now that we have our answers, we can simply put them into an ordered pair which should be in the form of (x value, y value.)
Our final answer will be (1, 1).
Hope this helps!

Answer with explanation:
Given : The heights of a certain population of corn plants follow a normal distribution with mean 
and standard deviation 
a) Using formula 
, the z-value corresponds to x= 135 will be
At x= 155, 
The probability that plants are between 135 and 155 cm tall :-
Hence, 34.73% of the plants are between 135 and 155 cm tall.
b) Sample size : n= 16
Using formula 
, the z-value corresponds to x= 135 will be
At x= 155, 
The probability that plants are between 135 and 155 cm tall :-
Hence,The percentage of the samples would the sample mean height be between 135 and 155 cm.= 93.12%
