18 is 15% of 120. Because 15% = 0.15 and 15% of 120 is 120x0.15= 18.
Answer:
Many techniques will simplify your work as you perform operations with algebraic fractions. As you review the examples, note the steps involved in each operation and any methods that will save you time.
Answer:
Place "SUM" at 4 on the number line.
Step-by-step explanation:
8 + (-4) = 8 - 4 = 4
Adding a negative number is the same as subtracting its opposite. Adding -4 is the same as subtracting 4.
The answer is 2 = p
Explanation: Here the goal is to get the variable "p" by itself, so first your have to distribute 2 to (p-12) which gives you -10p = 2p-24. Then you add 10p on both sides so that the variable is on one side. Then you add 24 to both sides. After that you divide 12 from both sides, giving you 2 = P
-10P = 2(p-12)
-10p = 2p-24
+10p +10p
0 = 12p-24
+24 +24
24 = 12p
24÷12 = 12p÷12
2 = p
Using the weighted mean, the coordinate of P is of P = -1.77.
<h3>What is the missing information?</h3>
This problem is incomplete, but researching it on a search engine, the points and weights are given as follows:
- D = 2 with a weight of 3.
- B = -6 with a weight of 9.
- A = -9 with a weight of 2.
- C = -1 with a weight of 3.
- E = 6 with a weight of 5.
<h3>What is the weighted mean?</h3>
The weighted mean is given by the <u>sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights</u>.
Hence, for the points this problem, the weighted mean is given as follows:
P = (2 x 3 - 6 x 9 - 9 x 2 - 1 x 3 + 6 x 5)/(3 + 9 + 2 + 3 + 5) = -1.77.
The coordinate of P is of P = -1.77.
