If three points were A, B and C are collinear points and B is between A and C, then AB+BC=AC
Answer:
A
Step-by-step explanation:
Carlos' score was 2 standard deviations from the mean, so his z-score was 2.0. You can either use the empirical 68-95-98.5 rule, or you can plug it into your calculator as <u>normalcdf(-999, 2) = .977</u>
So 97.7% of people had a score lower than Carlos!
.977 * 1.5 million = 1,465,500 people

Answer:
Option (2) CPCTC
Step-by-step explanation:
In the given regular triangle ADF, all sides and angles of the triangle will be equal
∠A = ∠D = ∠F = 60°
And DE = EF [Since E is the midpoint of side DF]
Statements Reasons
1). ∠D ≅ ∠F Given
2). ∠DBE ≅ ∠ECF Given
3). DE ≅ EF Given
4). ΔDBE ≅ ΔECF By AAS property
Therefore, DB ≅ FC
Option (2) Corresponding parts of the congruent triangles are congruent (CPCTC)
Just make the equations equal to each other. -0.5x+5=3x-2. Solve for x and find that it is 2, via simple algebra. Since you know x is 2, sub it in in either equation to find y. y should be 4. So the point that fits both equation is (2,4). This shows that the two graphs of these lines will intersect at this exact point.
If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.
