Answer:
The volume of the bottle is 46.56cm³
Step-by-step explanation:
Thinking of the bottle as a cylinder we can solve the problem as follows
radius = half of diameter
d = 2.4cm
r = 2.4cm / 2 = 1.2cm
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 10.3cm
π = 3.14
r = radius = 1.2cm
v = (π * r²) * h
we replace with the known values
v = (3.14 * (1.2cm)²) * 10.3cm
v = (3.14 * 1.44cm²) * 10.3cm
v = 4.52cm² * 10.3cm
v = 46.56cm³
The volume of the cylinder is 46.56cm³
Answer:
Step-by-step explanation:
Using the formula
p +/- z* √(p(1-p) / n)
Where p is sample proportion = 3226/3957 = 0.8153, n = 3957 and z* is 2.576
0.8153 + (2.576 √(0.8153(1-0.8153) / 3957))
0.8153 + (2.576 √ (0.8153(0.1847) /3957)
0.8513 + (2.576 √(0.1572/3957)
0.8513 + (2.576 √0.00003974)
0.8513 + 2.576(0.0063)
0.8513 + 0.016
0.8670 ~ 87%
For the lower interview
0.8513 - 0.016
= 0.8353 ~ 84%
Thus, at 99% confidence interval is 84% and 87%
Answer:
P (6 , -3)
Step-by-step explanation:
point P : (6 , -3)
Answer:
21 - n = 7 ; n = 14
Step-by-step explanation:
21 - 14 = 7
7 + 14 = 21
14 is 7 multiplied by 2 and 21 is 7 multiplied my 3
