Hello! So, the cost of $350, has been discounted by 20%. First off, let's find the discounted price. Even though there is a discount, 80% of the price still needs to be paid, because 100 - 20 = 80. Let's multiply. 350 * 80% (0.8) is 280. That's $280 on the dinette. The tax rate is 6.5%. To find the amount of tax, all you have to do is multiply the price by the tax rate. 280 * 6.5% (0.065) is 18.2. There. The tax is $18.20. The answer is B: $18.20.

Answer:
$18.20

Explanation:
The original price is $350
There is a discount of 20%
This means that the amount to be paid is 100% - 20% = 80% of the original price
Therefore:
amount to be paid = 80% * 350 = 0.8 * 350 = $280

Now, the tax rate is 6.5% of the paid price. This means that:
tax = 6.5% * 280 = 0.065 * 280 = $18.20

Hope this helps :)

Answer:

Probability that the mean daily precipitation will be 0.09 inches or less for a random sample of 40 November days is 0.103.

Step-by-step explanation:

We are given that according to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches; with a standard deviation of 0.05 inches.

A random sample of 40 November days is taken(taken over many years).

<u><em>Let </em></u> $\bar X$ <u><em> = sample mean daily precipitation</em></u>

The z score probability distribution for sample mean is given by;

Z = $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

where, $\mu$ = population mean = 0.10 inches

$\sigma$ = population standard deviation = 0.05 inches

n = sample of days = 40

Now, the probability that the mean daily precipitation will be 0.09 inches or less is given by = P( $\bar X$ $\leq$ 0.09 inches)

P( $\bar X$ $\leq$ 0.09 inches) = P( $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ $\leq$ $\frac{0.09-0.10}{\frac{0.05}{\sqrt{40} } }$ ) = P(Z $\leq$ -1.265) = 1 - P(Z < 1.265)

= 1 - 0.8971 = <u>0.1029</u>

<em>The above probability is calculated by looking at the value of x = 1.265 from the z table which will lie between x = 1.26 and x = 1.27 which has an area of 0.89617 and 0.89796 respectively.</em>

Hence, the probability that the mean daily precipitation will be 0.09 inches or less for a random sample of 40 November days is 0.103.
