A candy store called "Sugar" built a giant hollow sugar cube out of wood to hang above the entrance to their store. It took 13.5

Sunny_sXe [5.5K]

Answer:

$\frac{27}{8}m^3$ or $3.375m^3$

Step-by-step explanation:

The formula for volume is Base * Height * Width; and the formula for area is Base * Height.

This problem mentions the structure is a cube and therefore it is assumed that every wall has the same area. Since there are 6 sides to a cube you divide the total amount of ft which make up this cube to know the area to each wall.

$13.5 m/6$ = 2.25 or $\frac{9}{4} m$ per wall

With the area of each wall you can find the base and height:

base * height = area

$b=\sqrt{\frac{9}{4} } = \frac{3}{2}$

base = $\frac{3}{2}$ m

height = $\frac{3}{2}$ m

since: base=height=width, the width also equals $\frac{3}{2}$ m

volume = $(\frac{3}{2})^3$ = $\frac{27}{8}$

Describe different ways in which a plane might the cylinder,and the cross section the results.

Mademuasel [1]

The plane could be:
-perpendicular to the axis --> gives a circle
-parallel to the axis and tangent to the cylinder --> gives a line
-parallel to the axis and not tangent to the cylinder --> gives a pair of parallel lines
-neither perpendicular nor parallel to the axis --> gives an ellipse

All human blood can be "ABO-typed" as O, A, B, or AB, but the distribution of the types varies a bit among groups of people. Her

Tanya [424]

Answer:

a. Pr(They both have type O)

= Pr(They both have type O)

= 0.35 x 0.45

= 0.1575 = 15.75%

b. Pr( they both have the same blood type)

= Pr( they both have the same blood type)

= 2/8

= 0.25 = 25%

c. Pr( at least one person has type O)

= Pr (at least one person has type O)

= 1 - 0.3575

= 0.6425 = 64.25%

Step-by-step explanation:

a) Data:

O A B AB

Chinese 0.35 0.27 0.26 0.12

American 0.45 0.4 0.11 0.04

b) Calculations:

i. Pr(They both have type O)

= Probability of Chinese with O multiplied by Probability of American with O

= 0.35 * 0.45

= 0.1575 = 15.75%

ii. Pr( they both have the same blood type)

= Probability of two out of 8 outcomes

= 2/8

= 0.25 = 25%

iii. Pr( at least one person has type O)

= Probability of (1 – p(none) )

The probability of none = p(none O blood type)

= p(none)

for Chinese = (0.27 + 0.26 + 0.12) * for American ( 0.4 + 0.11 + 0.04)

= 0.65 * 0.55 = 0.3575

Pr (at least one person has type O) = 1 - 0.3575

= 0.6425
