Given the general term for calculating the nth term of a sequence;

Sn = n²

Where n is the number of terms.

To find the 99th term of the sequence using the nth term of the sequence;

Since we want to get the 99th term, this means that n = 99. Substituting n = 99 into the formula we will have;

S99 = 99²

Fed [463]

Answer:

0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.

Step-by-step explanation:

Probability of a defective part:

0.04 of \frac{100}{180}, that is, coming from A.

0.05 of \frac{80}{180}, that is, coming from B. So

p = 0.04\frac{100}{180} + 0.05\frac{80}{180} = \frac{0.04*100 + 0.05*80}{180} = 0.0444

0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.

A bicycle is $199.99 and it is marked 5% off. What is the sale price of the bicycle?
vagabundo [1.1K]
<span>Thus, a product that normally costs $199 with a 5 percent discount will cost you $189.05, and you saved $9.95.</span>

<span>You can also calculate how much you save by simply moving the period in 05.00 percent two spaces to the left, and then multiply the result by $199 as follows: $199 x .05 = $9.95 savings.</span>

<span>Furthermore, you can get the final price by simply deducting .05 from 1 and multiplying it by $199 as follows: (1 - .05) x $199 = $189.05 final price. </span>

<span>If something costs $199 and is on sale for 5% off, then how much would it cost? Here we will show you how to calculate how much you save (discount) and how much you have to pay if something you want to buy is regularly $199, but is currently on sale for 5 percent off.

<span>$199
<span>SALE
</span>5% OFF</span>
There are many ways of calculating your discount and final purchase price. One way is to multiply 199 dollars by 5 percent, and then divide the answer by one hundred, then deduct that result from the original price. See illustration below:

+ Purchase Price = $199
- Discount (199 x 5)/100 = $9.95
<span>= Final Price 199 - 9.95 = $189.05

</span></span><span><span>Hope this helps you! <3</span></span>
