1.2*3/2=1.8
Answer:
0.0778, 0.1789,0.0250
Step-by-step explanation:
Given that μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5
(Right tailed test)
To find p value:
a) Z = 1.42: p = 0.077804
=0.0779
b) z = 0.92
p value = 0.1789
c)z= 1.96
p value = 0.0250
Answer:
Step-by-step explanation:
<u>Use the Pythagorean theorem:</u>
<u>Verify this for each line:</u>
1.
- 28² + 45² = 53²
- 2809 = 2809
- Yes
2.
- 33² + 56² = 64²
- 4225 ≠ 4096
- No
3.
- 36² + 77² = 85²
- 7225 = 7225
- Yes
Answer:
Step-by-step explanation:
(x+6)(x+4)(x-3)
= [(x+6)(x+4)](x-3)
= (x² + 4x + 6x + 24)(x - 3)
= (x² +10x + 24)(x - 3)
= x³ - 3x² + 10x² - 30x + 24x - 72
= x³ + 7x² - 6x - 72
Answer: 
Step-by-step explanation:
Given
