The goal is to get x by itself. All we need to do is work around it.
1. -5x + 2 = 67
2. The reversed operation, or the opposite operation, for addition is subtraction. Thus subtract 2 from 67 and 2. The 2 should cancel itself out. -5x + [2-2=0] = 67 - 2 = 65 -> -5x = 65.
3. The reversed operation, or the opposite operation of multiplication is division. Thus divide 65 and-5 as well as -5 and -5. [-5/-5x = 1x. 1x -> 1 * x = x.] = 65/-5 = -13 -> x = -13.
4. Check your answer by plugging in -13 where x is. Solve with pemdas.
-5(13) + 2 = 67 -> 65 + 2 = 67 -> 67 = 67. Therefore the answer is -13.
Answer:
Second Choice ( AD, IH )
Step-by-step explanation:
Point A is the center of this circle.
The ratio of the lengths of ____ and ____ is 2:1
In the given diagram EF is the diameter of the circle.
BC is the chord of the circle. Diameter and chord length will vary.
AD is the radius of the circle. IH is the diameter of the circle.
Diameter of the circle IH is 2 times the radius AD
The ratio of the lengths of AD and IH is 2:1
Answer is option B
The probability distribution table is used to represent individual probabilities
The value of E(y) is 5.0
<h3>How to compute e(y)?</h3>
The value of e(y) is calculated using the following expected value formula
So, we have:
Evaluate
Hence, the value of E(y) is 5.0
