Answer:
circle and rectangle
Step-by-step explanation:
we know that
A cross section that is perpendicular to the base of cylinder is a rectangle
A cross section that is parallel to the base of cylinder is a circle
A cross section that is angled to the base of cylinder is an oval
Answer:
B: N-5
Step-by-step explanation:
N-5 is the same as a number (n) minus 5. decreased could also mean minus or subtract in simpler terms
Answer:
(26.2252 ; 27.3748)
Step-by-step explanation:
The confidence interval is given by :
x ± Margin of error
The margin of error = Zcritical * (σ/√(n))
σ = 7.5 ; n = 654
Zcritical = Zα/2 = 1.96
The margin of error = 1.96 * (7.5/√654) = 0.5748
The confidence interval :
Upper boundary = 26.8 + 0.5748 = 27.3748
Lower boundary = 26.8 - 0.5748 = 26.2252
(26.2252 ; 27.3748)
We are 95% confident that the mean BMI of the entire population will fall in between (26.2252 ; 27.3748)
Answer:
h = 39
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the volume is 10000pi and the diameter is 32
The radius is 32/2 = 16
10 000 pi = pi (16)^2 h
Divide each side by pi
10 000 pi/pi = pi/pi (16)^2 h
10 000= 256 h
Divide each side by 256
10000/256 = 256h/256
39.0625 = h
To the nearest whole number
h = 39
Answer:
AB + BC = AC
BC = AC - AB
5x + 6 = 37 - (2 x + 3) = 37 -2 x - 3 = 34 - 2 x
7 x = 34 - 6 = 28
x = 4
BC = 5 x + 6 = 5 * 4 + 6 = 26
Check:
AB = 2 x + 3 = 2 * 4 + 3 = 11
AB + BC = 26 + 11 = 37
