Any number that you can completely write down on paper using digits ... and a fraction bar or decimal point if necessary ... is a rational number. If you add it to 0.5, then the sum is another rational number.
Answer:
Forgive me if I'm wrong, but if I am correct that would be 30 people.
Answer:
The determinant is 15.
Step-by-step explanation:
You need to calculate the determinant of the given matrix.
1. Subtract column 3 multiplied by 3 from column 1 (C1=C1−(3)C3):
2. Subtract column 3 multiplied by 3 from column 2 (C2=C2−(3)C3):
3. Expand along the row 2: (See attached picture).
We get that the answer is 15. The determinant is 15.
Step-by-step explanation:
1/x^24 is the correct expression
Answer:
0.6808
Step-by-step explanation:
First, find the standard deviation of the sample.
s = σ / √n
s = 3 / √49
s = 0.429
Next, find the z-score.
z = (x − μ) / s
z = (28.8 − 29) / 0.429
z = -0.467
Use a calculator or z-score table to find the probability.
Using a table:
P(x > -0.47) = 1 − 0.3192 = 0.6808
Using a calculator:
P(x > -0.467) = 0.6796
