Answer:
c) H0 : p = 5.8%
H1 : p > 5.8%
Step-by-step explanation:
At the null hypothesis, we test that the percentage is equal to a certain value. At the alternate hypothesis, we have a test about this percentage, if it is more, less, or different from the tested value.
A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness
At the null hypothesis, we test if the percentage is 5.8%

At the alternate hypothesis, we test if this percentage is more than 5.8%. So

This means that the correct answer is given by option c.
Answer:
71.6056
Step-by-step explanation:
c² = a² + b² - 2abcosC°
29² = 30² + 15² - 2(30)(15)cosC°
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056
Answer:
28/7=n is what I believe would be the answer
Answer:
C
Step-by-step explanation:
3x^2 * -x =-3x^3
3x^2 * 2. =6x^2
4x* -x =-4x^2
4x * 2 = 8x
-5 * -x = 5x
-5 * 2 = -10
6x^2 + -4x^2 = 2x^2
8x+5x = 13 x
Ans: -3x^3 + 2x^2 + 13x -10
