Answer:
I got zero but I am not sure if that is right
Step-by-step explanation:
To find the perpendicular line a y- 2 = 7/3 (x + 5) you must first observe that the slope is m = 7/3, therefore, the slope of the perpendicular line put of the reciprocal, that is, m = - 3/7. So the possible options are A or C, but since the point (-4, 9) must go through the line, we find that the equation that satisfies that is option C.Therefore the perpendicular line that passes through the point (-4, 9) is C. y - 9 = -3/7 (x + 4)
Answer:
Confidence Level z*-value
90% 1.645 (by convention)
95% 1.96
98% 2.33
99% 2.58
Step-by-step explanation:
Thus, the difference in sample means is 0.1, and the upper end of the confidence interval is 0.1 + 0.1085 = 0.2085 while the lower end is 0.1 – 0.1085 = –0.0085.
Answer:
12 & 7
Step-by-step explanation:
12 + 7=19
12 - 7=5
Answer:
3
Step-by-step explanation:
-(x-4)+5=3x+6-x(BODMAS)
-x+4+5=3x+6-x(collect like terms )
4+5=3x+x-x
9=3x (divide both sides by 3)
9/3=3x/3
3=x
