Answer:
Step-by-step explanation:
Given given that
- Lower confidence interval = 7.1
- Upper confidence interval = 7.5
- As such, We are 95% confident that it's somewhere between 7.1 and 7.5 hours per night
Average value = LCI + UCI /2 = 7.1 + 7.5 / 2
= 7.3hours per night, so we are 95% confident that it's somewhere between 7.1 and 7.5 hours per night which is eventually 7.3hrs per night.
Answer:
The system of equations has no solution.
Step-by-step explanation:
Given the system of equations
2y = 2x+7
x = y+2
solving the system of equations
Arrange equation variables for elimination
Multiply -y+x=2 by 2: -2y+2x=4
so adding
so the system of equations becomes
0 = 11 is false, therefore the system of equations has no solution.
Thus,
No Solution!
3/5 of 7500 is 4500. That means 4500 chose coke. Now all u need to do is subtract 4500 from 7500 to get the amount of people that chose Pepsi. The answer would be 3000
Cos ( ∠C ) = 5/13 = 0.38462
m ∠C = cos^(-1) 0.38642 = 67.4°
m ∠A = 90° - 67.4° = 22.6°
m ∠C - m ∠A = 67.4° - 22.6° = 44.8°
Answer:
B ) 44.8°
Answer:
1200 mg
Step-by-step explanation:
16% = .16
.16x = 192
x =(192/.16)
x = 1200mg
