Answer:

37.67% probability that the pedestrian was intoxicated or the driver was intoxicated.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

945 accidents.

In 64 of them, the pedestian was intoxicated.

In 292 of them, the driver was intoxicated.

Probability that the pedestrian was intoxicated or the driver was intoxicated.

(64+292)/945 = 0.3767

37.67% probability that the pedestrian was intoxicated or the driver was intoxicated.

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are goi
AURORKA [14]

Answer:

<h2>He is going to pay 40*900= $36000 for the reservation</h2>

Step-by-step explanation:

Step one:

We are told that they need at least 50 total rooms.

Joe has paid for 16 rooms since Joe can only reserve rooms in block, and a block has 8 rooms, then Joe has paid for 2 blocks.

There is a deficit of 50-16= 34rooms

Required

The Number of blocks Joe need to reserve in addition is 34/8

=4.25

The blocks can not be in decimal, so we need to approximate, which is 5 blocks

Therefore Joe is going to reserve 5*8= 40 rooms

<u>He is going to pay 40*900= $36000 for the reservation</u>

Does someone mind helping me with this? Thank you!

\qquad\qquad\huge\underline{{\sf Answer}}

The given two polygons are similar to one another ~

Sides of the given polygons are in ratio of :

\qquad \sf  \dashrightarrow \: 28 : 4

to put in simple Ratio ~

\qquad \sf  \dashrightarrow \: 7: 1

So, the sides of the larger polygon are :

  • 4 × 7 = 28

  • 6 × 7 = 42

  • 3 × 7 = 21

  • 4 × 7 = 28

  • 7 × 7 = 49

  • 3 × 7 = 21

  • 3 × 7 = 21

  • 4 × 7 = 28

Now, to find the Perimeter of larger polygon ~ add the side length of all sides :

\qquad \sf  \dashrightarrow \:p = 28 + 42 + 21 + 28 + 49 + 21 + 21 + 28

\qquad \sf  \dashrightarrow \:238 \:  \: units
