Answer:

51

Step-by-step explanation:

when n=1

<h2><u><em>t 1=1 </em></u></h2>

<u><em>when n=2</em></u>

<u><em>t2=4</em></u>

<u><em>as first term is 1 and second term is 4 so the common difference is 3 ,for 6 term if you put this in formula for sum to the n term you will get 51 </em></u>

The number of typing errors made by a typist has a Poisson distribution with an average of five errors per page. If more than fi
xeze [42]

Answer:

0.61596

Step-by-step explanation:

Given that:

λ = 5 (5 errors per page)

Poisson distribution formula :

P(x = x) = (λ^x * e^-λ) / x!

Probability that page does not need to be retyped means that error on page is less than or equal to 5

P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)

The individual probabilities can be obtained using the formula above or the use of a calculator

P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674

P(x ≤ 5) = 0.61596

At a sale this week, a sofa is being sold for $272. This is a 36% discount from the original price. What is the original price?
Gwar [14]

Answer:

Step-by-step explanation:

A 36% discount means the selling price is (100-36)% = 64% of the original price.

$272 = 64% of x = 0.64·x

x = $272/0.64 = $425
