Answer:
0.726 < p < 0.874
Step-by-step explanation:
p = 64/83 = about 0.8
confidence interval = p +- z 
= 0.8 +- (1.64 x 0.04472)
= 0.8 +- 0.073343
= (0.726656 and 0.873343)
0.726 < p < 0.874
Answer:
-6x⁴y - 2x³y² + 9x²y³ - 3xy⁴ + y⁵
Step-by-step explanation:
(–2x³y² + 4x²y³ – 3xy⁴) – (6x⁴y – 5x²y³ – y⁵)=
–2x³y² + 4x²y³ – 3xy⁴ – 6x⁴y + 5x²y³ + y⁵=
-6x⁴y - 2x³y² + 9x²y³ - 3xy⁴ + y⁵
Answer:
A night stay and meal cost= $40.18
Step-by-step explanation:
Simultaneous equations
2n +4m=195 x 10
7n+10m=650 x 4
28n+40n= 2600
20n+40n=1950
Subtract
8n=650
1 night= 81.25
Substitute
81.25 x 2 +4m=195
162.5+4m=195
4m= 32.5
1 meal= 8.13
1 night and meal= $40.18
