Answer:

a. 12.4 mi

Step-by-step explanation:

Hello

this is a unit conversion problem,you must know the equivalence

in this case

1 mi. ≈ 1.61 km.

Now, we need to convert 20 Km into miles

we can use a simple rule of three

1 mi. ⇔ 1.61 km

x mi. ⇔ 20 Km

$\frac{x (mi)}{20 Km} =\frac{1 mi}{1.61 Km} \\\\Now\ isolating\ x\\\ \\x(mi)=\frac{20km*1mi}{1.61 Km} \\x=12.42\ mi\\$

a. 12.4 mi

Have a fantastic day.

Dean won a trip to the upcoming Winter Olympics and needs to plan which events to attend. During the first week of competition,

zlopas [31]

Answer:

6 different orders

Step-by-step explanation:

Given:

Number of events taking place = 3 (Speed skating, ice hockey and cross-country skiing)

Now, Dean plans to attend ne round from each one of them.

The questions asks us to find the different orders in which Dean can attend each event.

So, this is a question of permutations as order of events is important here.

So, number of ways to attend 1 event out of 3 events is 3.

Now, there are 2 events left. Number of ways of attending 1 event out of the remaining two events is 2 ways.

Now, only one event will be left. So, Dean will finally attend that event.

Thus, total number of different orders in which Dean can attend one round of all the 3 events is given as:

$=3\times2\times 1\\=6$

Hence, Dean can attend each of the three events in 6 different orders.

Answer:

b) The Pie Eating Contest would be more skewed

Step-by-step explanation:

Let's begin by drawing out a frequency distribution table for the given information:

Pie Eating Contest

Age Group (Years) Frequency

0 - 19 20

20 - 39 40

40 - 59 60

60 - 79 50

If all 20 people (aged 75 - 79) joined this event, the frequency tables changes to become:

Pie Eating Contest (2)

Age Group (Years) Frequency

0 - 19 20

20 - 39 40

40 - 59 60

60 - 79 70

Chili Cookoff

Age Group (Years) Frequency

0 - 19 30

20 - 39 50

40 - 59 40

60 - 79 10

If all 20 people (aged 75 - 79) joined this event, the frequency tables changes to become:

Chili Cookoff (2)

Age Group (Years) Frequency

0 - 19 30

20 - 39 50

40 - 59 40

60 - 79 30

The graphical representation of each event is attached as a picture

A histogram is skewed if its frequency distribution is biased to one side (either to the left or to the right). This implies that the histogram is not evenly distributed. When the histogram is cut into equal halves, the left side and the right side look unidentical.

A histogram is symmetrical if its frequency distribution is neither biased to the right or to the left. It implies that the histogram is evenly distributed across the left and the right side. When the histogram is cut into equal halves, the left side and the right side look identical.

When we consider the event in which all 20 people join the Pie Eating Contest, the histogram becomes skewed to the right.

When we consider the event in which all 20 people join the Chili Cookoff, the histogram becomes more symmetrical

We will observe that when all 20 people joined the Pie Eating Contest, the histogram becomes more skewed to the right and less symmetrical. On the other hand, if all 20 people join the Chili Cookoff, the histogram becomes more symmetrical and less skewed

Hence, the correct answer is option b) The Pie Eating Contest would be more skewed

A dishwasher uses 11 liters of water for each cycle. A washing machine uses 5 times as much water as a

castortr0y [4]

Answer:

55,000 milliliters

Step-by-step explanation:

So if washing machine uses 5 times more than dishwasher

Dishwasher: 11 litters of each cycle

Washing machine: 11 x 5= 55 litters for each machine in litters

If 1 litter is equal to 1000 milliliter then 55 x 1000 = 55,000 milliliters

FORMULA for milliliter: multiply the volume value by 1000

Hope this helps
