Answer:
2) Subtraction Property of Equality Properties
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Addition Property of Equality - Adding on both sides
- Subtraction Property of Equality - Subtracting on both sides
- Multiplication Property of Equality - Multiplying on both sides
- Division Property of Equality - Dividing on both sides
- Transitive Property - If a = b and b = c, then a = c
- Symmetric Property - If a = b then b = a
Step-by-step explanation:
<u>Step 1: Define</u>
4m + 1 = 7 → 4m = 6
<u>Step 2: Identify</u>
We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.
Answer: Hello your question is poorly written attached below is the complete question
answer : 101.8
Step-by-step explanation:
Given data :
Standard deviation ( б ) = 14
55% have IQ scores > 100
45% have IQ scores < 100
<u>Determine the mean IQ score for the region</u>
P ( X > x ) =
P ( Z ≥ ( 100 - μ ) / 14 ) = 0.55 also
P ( Z ≤ ( 100 - μ ) / 14 ) = 0.45
<em>using standard normal calculator </em>
100 - μ / 14 = Z₀.₄₅ = - 0.126
<em>resolving the relation above</em>
100 - μ / 14 = - 0.126
μ = 100 - 14 ( -0.126 )
= 101.764 ≈ 101.8
Answer:
-20/33
Step-by-step explanation:
y2 - y1 / x2 - x1
1/6 - (-1/4) / -5/16 - 3/8
5/12 / -11/16
= -20/33
