S_A_V [24]

Answer: 0.9

Step-by-step explanation:

$\mathrm{Total \ sample \ space \ $=100$} \\\mathrm{Event \ $A = \ taking \ subway \ each \ day}$$P(A)=0.85$$Event $B=$ taking taxi $\because P(B)=0.6$$$P(A \cap B)=0.55$$$

$\begin{aligned}P(A \cup B) & \Rightarrow \text { Person taking either taxi/subway } \\&=P(A)+P(B)-P(A \cap B) \\&=(0.85-0.555)+(0.6-0.55)-0.55 \\&=1.45-0.55\\&\bf{=0.9} \end{aligned}$

What is the volume of the rectangular prism? A prism has a length of 6 meters, height of 4.5 meters, and width of 5.5 meters. 16

Sidana [21]

Answer:

148.5 meters^3

Step-by-step explanation:

The volume of a rectangular prism can be found using the following formula.

V=l*w*h

The length is 6 meters. The height is 4.5 meters. The width is 5.5 meters. Substitute these values into the formula.

V=6*5.5*4.5

Multiply all the values together

V=33*4.5

V=148.5

Add appropriate units. Volume uses units^3 and the units are meters.

V=148.5 meters^3

The volume of the rectangular prism is 148.5 cubic meters.
