inn [45]3 years ago
3 0

Answer:

<h3>$21.54</h3><h3 />

Step-by-step explanation:

price paid    = regular price ( 1 + coupon in percent)

             $28 = regular price x (1.3)

regular price = $28 / 1.3

                     = $21.54

What are the rate of changes for
astraxan [27]
<span>39 & 16.5 = -22.5
30 & 12.4 = -17.6
28 & 10.4 = -17.6
19 & 10.3 = -8.7
23 & 11.2 = -11.8
if the values are y values you will subtract them from each other to get the numerical value and because they all go from a larger number to a smaller number the rate is a negative. if they were from a smaller value to a larger value teh rates of change would be positive.

A shipment of inexpensive digital​ watches, including that are​ defective, is sent to a department store. The receiving departme
Wittaler [7]

0.8926 percent of the time, the shipment will be rejected.

<h3>What is Probability?</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

<h3>According to the given information:</h3>

A delivery of 50 cheap digital watches, 10 of which are flawed.

A digital watch's likelihood of malfunctioning

P = 10/50

= 0.2

Size of sample: n = 10

Additionally, if they find one or more samples to be defective, they reject the entire cargo.

Making use of the binomial probability formula:

P(x)={ }^{n} C_{x} p^{x}(1-p)^{n-x}

The random variable x should stand in for the quantity of defective watches.

The chance that the delivery will be refused is:

\begin{aligned}&P(x \geq 1)=1-P(0) \\&=1-{ }^{10} C_{0}(0.2)^{0}(0.8)^{10}\end{aligned}

= 1 - (0.8)

= 0.8926

As a result, 0.8926 percent of the time, the shipment will be rejected.

I understand that the question you are looking for is:

A shipment of 50 inexpensive digital​ watches, including 10 that are​ defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be​ rejected

Q1: Payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. Calculate the
zhuklara [117]

Answer:

$50,281.04

Step-by-step explanation:

5 years is equivalent to (5 × 12) = 60 months

Now, the first payment $670 is compounded for 60 months at the rate of \frac{8}{12} = 0.667% monthly interest.

So, it will become 670(1 + \frac{0.667}{100})^{60} = 670(1.0067)^{60}.

Similarly the second payment of $670 will become 670(1.0067)^{59}

Therefore, in this way after 60 months i.e. 5 years the total sum will be

= 670 + 670(1.0067)^{1} + 670(1.0067)^{2} + 670(1.0067)^{3} + ........ + 670(1.0067)^{59} + 670(1.0067)^{60}

= 670[1 + (1.0067) + (1.0067)^{2} + (1.0067)^{3} + ....... + (1.0067)^{59} + (1.0067)^{60} ]

= 670[1 \times \frac{(1.0067)^{61} - 1 }{1.0067 - 1} ]

= $50,281.04 (Answer)

{Since, the sum of the G.P. series 1 + r + r^{2} + r^{3} + .......... + r^{n} = 1 \times \frac{r^{n + 1} -1}{r - 1} }
