Answer:
-200 metre is less 450m because - 200 metre is negative.
Answer:
4
explanation:
well 18 minus 12 would equal 6. correct? so we would add x to 6 so the new equation would be 6 + x = 10 or to make it easier just do 10 - x = 6
To solve this, we use the z test.
The formula:
z = (x – u) / s
where x is sample value = 20, u is the mean = 15, and s is
the standard deviation = 2.5
z = (20 – 15) / 2.5
z = 2
Since we are looking for values greater than 20, this is
right tailed test. We use the standard distribution tables to find for P.
P = 0.0228
Therefore:
number of students = 100 * 0.0228 = 2.28

Answer:
C. p(x) = 5x - 12.
Step-by-step explanation:
p(x) = 8x - (3x + 12) (Note you have to put the 3x+12 in parentheses).
p(x) = 8x - 3x - 12
p(x) = 5x - 12
