The answer is A. And here's how you get it. You start by simplifying between the numerator and the denominator in the top fraction. Factor the top and the botttom so you have this: [7(x+3)/(x+3)(x+2)]/[(x+6)/(x+2)]. The (x+3)'s in the top fraction cancel each other out leaving you with [7/(x+2)]/[(x+6)/(x+2)]. When you divide fractions by fractions you change the sign and flip the fraction in the denominator so now you have this: [7/(x+2)]*[(x+2)/(x+6)]. The (x+2)'s cancel each other out then leaving you with 7/(x+6)
Answer:
He sold 960 kg
Step-by-step explanation:
Let the initial stock measure be x kg
So if he sold 45% ; what he sold was;
45/100 * x = 0.45x
So the quantity left would be;
x - 0.45x = 0.55x
So what was left is 96kg more than what was sold
Mathematically, we have this as;
0.55x - 0.45 x = 96
0.1x = 96
x = 96/0.1
x = 960 kg
Y=12.5x
because 12.5 is the constant and this is a directly proportional equation
Answer:
The distribution of sample means will form a normal distribution
Step-by-step explanation:
Answer:
<h2><em>
n = 11</em></h2>
Step-by-step explanation:
n + 1 = 4(n - 8)
n + 1 = 4n - 32 [Multiply 4 times (n-8)]
1 = 3n - 32 [Subtract 1n from both sides]
33 = 3n [Add 32 to both sides]
3n = 33
<h2><u>
n = 11</u></h2>
CHECK:
Does n + 1 = 4(n - 8) when n = 11?
n + 1 = 4(n - 8)
11 + 1 = 4(11 - 8)
11 + 1 = 4(3)
12 = 12 YES
