Afactory produces 1000 bottles of pasta sauce in a day. fifty bottles are selected at random to determine if they weigh the correct amount. the factory rejects bottles that are over or under the correct weight.

one bottle is under weight, 46 bottles are the correct weight, and 3 bottles are over weight.

based on this random sample, approximately how many bottles will the factory reject from the day's production?

a.4

b.20

c.60

d.80

option: D is correct.

Step-by-step explanation:

The random sample is given of 50 bottles which is depicted as:

1 bottle under weight

46 bottles correct weight

3 bottles over weight

As the bottles which are under weight and over weight are rejected.

that means out of 50: 4 bottles are rejected.

Now we have to find out the number of bottles rejected out of the 1000 bottles.

As 1000 is 20 times of 50.

Hence the number of bottles rejected will also get multiplied by 20.

Hence total number of bottles rejected=80.

Hence, option D is correct.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
