- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x = 2y - 5
-2x + 5y = 11
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: -2(2y - 5) + 5y = 11
- Distribute -2: -4y + 10 + 5y = 11
- Combine like terms: y + 10 = 11
- Isolate <em>y</em>: y = 1
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x = 2y - 5
- Substitute in <em>y</em>: x = 2(1) - 5
- Multiply: x = 2 - 5
- Subtract: x = -3
What units are the numbers? Assume they are in millimeters (i am just assuming).
<span>Then the IQR is 7 millimeters and the range is 12 millimeters. </span>
<span>If they haven't given any units in your questions, you cannot write the answer using units.
i hope this answers your question</span>
Answer:
Probability =0.8854 (Approx)
Step-by-step explanation:
Given:
Mean μ = 100
Standard deviation σ = 15
Computation:
Z at 70
Z = (70-100)/15
Z at 70 = -2
Z at 120
Z = (120-100)/15
Z at 100 = 1.33
Probability = φ(1.33) - φ(-2.0)
Probability = 0.9082-0.0228
Probability = 0.8854 (Approx)
The two points shown are (0, -4) and (2, 0).
slope = (-4 - 0)/(0 - 2)
Answer is B. (-4 - 0)/(0 - 2)
