A criminologist has developed a questionnaire for predicting whether ateenager will become a delinquent. Scores on the questionn
Reika [66]

Answer:

Probability=0.8413

So option A is correct.

Step-by-step explanation:

In order to find the probability that the criminologist will classify all of them as delinquents, we will proceed as following:

We are required to find:

P(m>=75|m-N(80,5))

it can be written as:

1-P(m<75|m-N(80,5))

P(m<75|m-N(80,5)) can be solved as

Z=(75-80)/5

Z=-1

Probability = 1-Z(-1)

Fromm distribution table:

Probability=1-0.15866

Probability=0.8413

So option A is correct.

Rewrite as a simplified fraction.<br> 3.541<br> 41 is repeating
dmitriy555 [2]

If <em>x</em> = 3.5414141…, then 10<em>x</em> = 35.414141… and 1000<em>x</em> = 3541.414141…. Then

1000<em>x</em> - 10<em>x</em> = 3541.414141… - 35.414141…

990<em>x</em> = 3506

<em>x</em> = 3506/990 = 1753/495

The design of a nomadic tribal rug is shown, where m&lt;AED=34° and m&lt;EAD=112°
Lady_Fox [76]

The required angle m∠ADB  of the nomadic tribal rug is 112°

Given, that in ΔAED and ΔBDC,

where, m∠AED = 34° and m∠EAD = 112°

To find m∠ADB

By using the angle sum property of a triangle, which states that the sum of interior angles of a triangle is 180°.

Therefore in ΔAED,

m∠AED + m∠EAD +  m∠ADE = 180°

   34°  +    112°    +   m∠ADE   = 180°

or,    m∠ADE + 146° = 180°

or,       m∠ADE    = 34°

Similarly, m∠BDC = 34°

Now, by using the sum of linear pair of angles,

m∠ADE + m∠ADB + m∠BDC = 180°

  34° + m∠ADB + 34°  = 180°

   m∠ADB + 68° = 180°

   m∠ADB  = 180°- 68°

    m∠ADB = 112°
