The notation just means
(f/g)(-4) = f(-4) / g(-4)
If f(x) = x² + 2 and g(x) = 1 - 3x, then
f(-4) = (-4)² + 2 = 16 + 2 = 18
g(-4) = 1 - 3 (-4) = 1 + 12 = 13
and so
(f/g)(-4) = 18/13
Answer:
<h2><u><em>
15</em></u></h2>
Step-by-step explanation:
what is the value of 10×+z=150
10× (+z) = 150
10 × z = 150
z = 150 : 10
z = 15
-----------------------
check
10 × 15 = 150
the answer is good
Answer:
Z = 6
Step-by-step explanation:
Z/12 = Cos(60°)
Z/12 = 1/2
Statistic significance requires that your sample be representative of the population, but I'm struggling with this because if the class is an elective then the answer would be: <span>No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school.
BUT if the class is required, as most science classes are, then it WOULD be a random sample of the school. So the last option would be correct.
My guess though is that the teacher is looking for answer B.

Answer:
The smallest number n could be is 64.
Step-by-step explanation:
35 + 64 = 99
64/8 = 8
= √289 = 17
