As a promotion a clothing company sent out an email with a link where recipients have a 1/20 probability of receiving a 40% off coupon. Otherwise, they receive a 5% off coupon. If 340 of the recipients click the link, what is the best prediction for the number of recipients that received a 40% off coupon.

17

Step-by-step explanation:

In this case we know that there are a total of 340 recipients and they tell us that of 20 recipients only 1 receipt of the 40% discount.

So what you need to do is apply the probability to the total recipients, like so:

Number of recipients with 40% = Total recipient * probability of 40%

N = 340 * (1/20)

N = 17

Which means that the best projection is that only 17 people out of those 340 will benefit from the 40% discount.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

me! what did you put for this question?
