6z - 12 + 4 = 10
6z -8 = 10
6z = 18
z = 3

Answer: 405 students
Step-by-step explanation:
From the question, Banneker Middle School has 750 students and we are told that Lynn surveys a random sample of 50 students and finds that 27 have pet dogs. The number of students at the school that are likely to have pet dogs goes thus:
Since out of 50 students surveyed, 27 have pet dogs, this means we multiply the fraction by 750. This can be mathematically written as:
= 27/50 × 750
= 27 × 15
= 405
This means 405 students are expecting to have pet dogs.
Answer:
0.012
Step-by-step explanation:
Linear approximation says that,

For a cube the surface area is
.
So the side is 1.0 inch in, the surface area is
square inches.
In Linear approximation means you ignore the term
, if
is a small number, because then
will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,

So here, 
The error in the area is approximately,

So the error is 0.012.
