hope this helps!
if you graph these equations, they will intersect at (4,1). They look very short because they are vertical and horizontal.
Step-by-step explanation:
The answer to this question is X>0 because if u work it out then the value of X will be greater than 0.
Find the perimeter of the triangle and your answer is yellow
Answer:
a. no, there are no sufficient data to use
b. assumption b is right
Step-by-step explanation:
a. for the standard deviation to be calculated at 99% confidence, the data needed should be the mean (given), the variate value to be calculated for(not given), the standard deviation(not given), the z value of the normal distribution ( not given),
since there are too many unknown, the data given are not sufficient to calculate.
b. validity of this interval requires that coating layer thickness be at least approximately normally distributed.
16 to 18 simplifies down to 8 to 9 because you divide 2 to both terms
24 to 27 simplifies down to 8 to 9 because you divide 3 to both terms
So yes
A
