Alan is arranging 3 different stuffed toys in a row on a shelf. Create a sample space for the arrangement of a teddy bear (T), a

belka [17]

Answer:

In the row, we will have 3 positions.

first position

second position

third position.

Let's use the notation:

(1, 2, 3)

to describe the first, second and third positions respectively.

If we can put 3 elements there (a teddy bear (T), a kitten (K), and an elephant (E))

The sample space will be all the possible elements of the form (1, 2, 3)

For example, the element where the teddy bear is in the first position, the kitten is in the second position, and the elephant is in the third position can be written as:

(T, K, E)

And because a single toy can not be in two different positions, the elements like (T, T, T) are not allowed, so the sample space will be the set of the permutations of:

(T, K, E)

(So we just reorder these elements in all the possible different ways)

That set is:

(T, K, E); (T, E, K); (E, T, K); (E, K, T); (K, T, E), (K, E, T)

Then the sample space will be:

S = {(T, K, E); (T, E, K); (E, T, K); (E, K, T); (K, T, E), (K, E, T)}

A space defined by these 6 elements.

1. There are 100 cm in 1 m and 1000 m in 1 km. You need a curtain for a window that is 156 cm wide.

DIA [1.3K]

Part 1)There are 100 cm in 1 m and 1000 m in 1 km. You need a curtain for a window that is 156 cm wide.

Part (a) If you wanted to convert the width to kilometers, what conversion factor should you use? Show your work.

we know that
100 cm------> 1 m
1000 m-----> 1 km

step 1
convert cm to m
156 cm---------> 156*(1/100)-----> 1.56 m

step 2
convert m to km
1.56 m------> 1.56*(1/1000)----> 0.00156 km

step 3
find the factor
156 cm---------> 156*(1/100)*(1/1000)---> 156*[1/100000]=0.00156 km

the answer part 1a) is
the conversion factor is (1/100000)

Part (b) What is the width in kilometers?

the answer Part 1b) is 1.56 km

Part 2) The driver of a taxi charges $2 every minute plus a pickup fee of $3.
Part (a) Write an expression for the total cost of a taxi ride.

let
x-----> quantity of minutes of a taxi ride
y----> total cost of a taxi ride

we know that
y=2x+3

the answer Part) 2a is
An expression for the total cost of a taxi ride is
y=2x+3

Part b) How much does an 18-min drive cost?
y=2x+3
for x=18 minutes
y=2*18+3-----> y=$39

the answer Part 2b) is
$39

Part 3) Draw a net for each of the following shapes:
(a) Rectangular prism
(b) Triangular prism
(c) Pyramid
