A store manager receives a delivery of 10 boxes of lightbulbs. Each box contains 20 lightbulbs. The store manager tests all the lightbulbs in one of the boxes and finds that 4 of them are defective.

Which statement about the lightbulbs in the remaining boxes is best supported by this information?

Between 25 and 50 lightbulbs will be defective.


More than 80 lightbulbs will be defective.


Between 60 and 80 lightbulbs will be defective.


No more than 25 lightbulbs will be defective.

Answers

Answer 1
We can expect that there will be about 4 broken lightbulbs in each of the 10 boxes, which is 40 lightbulbs. This means between 25 and 50 lightbulbs will be defective.

Convert 639 into quinary system​

Answers

Step-by-step explanation:

To convert decimal number 639 to quinary, follow these steps:

Divide 639 by 5 keeping notice of the quotient and the remainder.

Continue dividing the quotient by 5 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 639.

Using the above steps, here is the work involved in the solution for converting 639 to quinary number:

639 / 5 = 127 with remainder 4127 / 5 = 25 with remainder 225 / 5 = 5 with remainder 05 / 5 = 1 with remainder 01 / 5 = 0 with remainder 1

Then just write down the remainders in the reverse order to get the answer, The decimal number 639 converted to quinary is therefore equal to :

Why might Razis method not be a good way to estimate the probability? My team won 18 of their last 20 matches, so the probability that they will win their next match is 18/20 = 90%

Answers

Answer:

It is a really idealistic way to estimate probability.

It usually works well for random events where there is no restriction like:

"There are N elements in a set, the probability of randomly selecting any element is the same (so there is no restriction) meaning that for every single element, the probability is 1/N.

Now suppose that there are K elements (K < N) with a given characteristic, then the probability of randomly selecting one of the K elements out of the sett with N elements is equal to K times the probability of each element, this is:

P = K*(1/N) = K/N"

Then if a dice has 6 possible outputs, and we want to find the probability of getting a 3 or a 5, we need to find the quotient between the outcomes where we get a 3 or a 5 (2) and the total number of outcomes (6)

P = 2/6

Now let's go to the case in the problem:

We know that out of the last 20 games, your team won 18.

Then yes, your team won (18/20)*100% = 90% of their played games.

Does this mean tath the probability of winning the next game is 90%?

Well no, because this is not a random selection, there are a lot of other things needed to analyze, as the win rate of the other team (suppose that the other team won 14 of their last 20 games, then their win rate is (16/20)*100% = 70%

Does this mean that the probability where our team wins is 90%, and the probability of the enemy team winning is 70%?

Well no, this makes no sense at all, and this is why this method is not a good way to estimate probability in complex cases like this one.

Ian went to a music store to buy a guitar. The guitar which he picked out was $350. He found out that there was a sale that day and all guitars were 20% off. Since he had a rewards card at the music store,he was also able to receive 5% off the sale price. How much did Ian pay, without tax,for the guitar?

Answers

Answer:

$266

Step-by-step explanation:

The amount did Ian pay, without tax,for the guitar is to be considered as the $266 when the off and discount are given.

Calculation of the amount:

Since the cost of the guitar is $350

There is 20% off.

And, there is 5% off the sale price

So, it be like

= 350 (1 - 0.20) (1 - 0.05)

= $266

hence, The amount did Ian pay, without tax,for the guitar is to be considered as the $266 when the off and discount are given.

Can you please help solve for x?
x+6+x-2=180

Answers

Answer:

x=88

Explanation:

x+6+x-2=180

2x+4=180

2x=180-4

2x=176

*divivd both sides*

x=88

Answer:

x = 88

A = 94°

B = 102°

C = 86°

D  = 78°

Step-by-step explanation:

We find the angle measurements by finding x first.

what we first do in this equation x+6+x-2=180 is combine like terms

this would equal

2x+4=180

we want x by itself so we subtract 4 from both sides

this would equal

2x=176

x is still not by itself so now we divide 2 by both sides

this would equal

x = 88

Now we just plug in our answers in to the angles meaning

we replace everything that is x in the quadrilateral with 88

Now that we found all the sides with equations there is still one angle that is undefined

We figure this out by subtracting all the angles with 360.

this is because all the angles degrees added in a quadrilateral equals 360. so 360-258=102

so the angle measurement of angle B is 102
