Answer:

48 feet

Step-by-step explanation:

Distance = rate × time

d = 12 ft/min × 4 min

d = 48 ft

The diver will be 48 feet below the surface.

Answer:

-48 ft

Step-by-step explanation:

The unit rate of descent is

  -12 ft

-----------

  1 min

and so after 4 minutes, the diver will be 48 ft beneath the surface:

  -12 ft

----------- * 4 min = -48 ft

  1 min

There are 3 directors, 4 management executives, 2 statisticians and 1 administrator. A committee of 4 members among them is to b
Vsevolod [243]

Answer:

1) 4/35

2) 11/14

3) 5/6

Step-by-step explanation:

First find the number of selections possible.

\frac{10!}{(10-4)!4!} = 210

There are 210 possible selections. Now we can determine the possibility for each group. For the first probability, since we only want one member from each committee, you would create a fraction by (group members in total / group member being extracted). For this instance, since its only one, we will do whole numbers. Multiply each other.

4*3*2*1=24

The probability for each member to get selected from each kind is : 24/210 or can be simplified to 4/35.

The probability of (I assume) at least one administrator is slightly different. Separate our two selections, the other three and the administrator. Find the number of selections possible for the other three... 4+3+2 = 9 others.

Find the probability for both a administrator included and three others.

\frac{11}{3} * \frac{1}{1} \\\frac{11!}{(11-3)!3!} \\\\165

\frac{165}{210} = \frac{11}{14}

The probability for an administrator and the other three is 165/210 or 11/14.

For the last one, you will figure out what the probability is for no director and use that % to substract from 100.

4+2+1 = 7

Get selections possible.

\frac{7!}{(7-4)!4!} = 35

Get probability of no director.

\frac{35}{210} = \frac{1}{6}

Substract 1/6 from 100%

1 - 1/6 = 5/6

The probability of having at least one director is 5/6.

The circle graphs show the percentage of men and women from Country X who consider owning a home an important part of adult life
morpeh [17]

Answer: a) 76 : 24

              b) 24 : 76

Step-by-step explanation: <u>Odds</u> describe the possibility an event will occur, i.e., is the ratio of an event being successful with the chance of an event failing. It can be in favor or against:

  • <u>Odds</u> <u>in</u> <u>favor</u> is expressed as: favor=\frac{favorable}{unfavorable};
  • <u>Odds</u> <u>against</u> is expressed as: against=\frac{unfavorable}{favorable};

a) Odds in favor

favor=\frac{76/100}{24/100}

favor=\frac{76}{24}

or

favor = 76 : 24

Odds in favor of a man agreeing owning a house is an important part of adult life is 76 : 24.

b) Odds against

against=\frac{24/100}{76/100}

against=\frac{24}{76}

or

against = 24 : 76

Odds against of a man agrreing that owning a house is an important part of adult life is 24 : 76
