2(3/4)=5<br> 3(4×2)=1<br> 1/4+4/3

Andrej [43]

Answer:

$2( \frac{3}{4} )= 5 \\ \frac{3}{2} = 5 \\ 3 = 5 \times 2 \\ 3 = 10$

$3( 4 \times 2) = 1 \\ 3(8) = 1 \\ 24 = 1$

$\frac{1}{4} + \frac{4}{3} \\ \frac{1}{1} + \frac{1}{3} \\ 1 \times 3 + 1 \times 1 \\ 3 + 1 \\ 4$

An installation technician for a specialized communication system is dispatched to a city only when 3 or more orders have been p

bazaltina [42]

Answer:

0.3233

0.09

Step-by-step explanation:

Given that :

Mean, λ = 0.25 for a 100,000 per week

For a population of 800,000 :

λ = 800,000 / 100,000 * 0.25 = 8 * 0.25 = 2 orders per week

Probability that technician is required after one week ;

After one week, order is beyond 2 ; hence, order, x ≥ 3

P(x ≥ 3) = 1 - [p(x=0) + p(x= 1) + p(x =2)]

P(x ≥ 3) = 1 - e^-λ(1 + 2¹/1! + 2²/2!)

P(x ≥ 3) = 1 - e^-2(1+2+2) = 1 - e^-2*5 = 1 - e^-10

P(x ≥ 3) = 1 - e^-2 * 10

P(x ≥ 3) = 1 - 0.6766764

P(x ≥ 3) = 0.3233

B.)

Mean, λ for more than 2 weeks = 2 * 2 = 4

P(x < 2) = p(x = 0) + p(x = 1)

P(x < 2) = e^-4(0 + 4^1/1!)

P(x < 2) = e^-4(0 + 4) = e^-4(5)

P(x < 2) = e^-4(5) = 0.0183156 * 5 = 0.0915

P(x < 2) = 0.09

3. Bob has 8 pieces of square index cards that each measures 8 inches per side. Using a pair of scissors, he cuts each piece in

const2013 [10]

The number of pieces of card stock which would result upon the process repetition is; 256 pieces.

<h3>What is the number of card stock pieces resulting from the cutting process?</h3>

According to the task content, it follows that since, there are 8 pieces of the 8 inches per side cards initially, the resulting number of cards after carrying out the process of cutting cards into half five, 5 times is;

No of cards = 8 (2)⁵

No. of cards = 256 pieces.

The size of each of the cards in discuss provided that all cuts will be made along and not across the longer edge is; 8 by 1/4 inches.

2- log 6-log 9<br> In condensing

Tju [1.3M]

Answer:

$\log(150)$

Step-by-step explanation:

We want to rewrite the following as a single logarithm:

$2 - log(6) - log(9)$

We introduce logarithm in the first term to get:

$2 \log(10) - \log(6) - \log(9)$

Recall that:

$log(a) - log(b) = \log \frac{a}{b}$

We apply this property to get:

$2 log(10) - log( \frac{6}{9} )$

This gives:

$log( {10}^{2} ) - log( \frac{6}{9} )$

$log( {100}) - log( \frac{2}{3} )$

$log( \frac{100}{ \frac{2}{3} } ) = log( \frac{300}{2} ) = log(150)$
