7 0

Answer:

7/16

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

Proportion of defective televisions in the shipment = 15/240 = 1/16

Probability that 1 of the 7 chosen is defective = 1/16 x 7 = 7/16

Complete the following by calculating the cash discount and net amount paid:
Fittoniya [83]

Based on the terms of the invoice, the gross amount on the invoice and the date of payment, the cash discount is $19 and the net amount paid is $931.

<h3 /><h3>What is the cash discount?</h3>

The terms of the invoice are such that if the person pays within 10 days they get a 3% discount. If they pay in 15 days, they get a 2% discount.

The person paid on the 22nd after buying on the 8th so they qualify for the 2% for paying within 15 days.

The cash discount is:

= 2% x 950

= $19

The net amount paid is:

= 950 - 19

= $931

Calculate the center angle a if the lenght of the circular arc 31,4cm and the radius of the circle 9cm​
Fed [463]

Answer:

3.49 radians

Step-by-step explanation:

The arc length formula is s = rФ, where r is the radius and Ф is the central angle.  We know s and r and need to calculate Ф.

From s = rФ we get Ф = central angle = s/r

Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
