Answer: 99.73%
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Let X be the random variable that represents the data values.
Formula for Z-score : 
For x=94, we have
For x=106, we have
The probability that the samples are between 94 and 106:-
Hence, the percent of the samples are expected to be between 94 and 106 = 99.73%
Answer:
The slope of the line is constant. This is because all straight lines have a constant slope. The slope of this line is 1/3. When you use the legs to measure, the horizontal legs of the triangle, they increase in length by 3 units from the previous triangle. The vertical legs of the triangle also increase by 1 with each added triangle. Both of these observations support that the slope of the line is a constant 1/3.

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -3x² - 7x
f(7) is x = 7
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(7) = -3(7)² - 7(7)
- Exponents: f(7) = -3(49) - 7(7)
- Multiply: f(7) = -147 - 49
- Add: f(7) = -196
