Total number of computers in sample = 72 + 112 + 711 = 895.
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Answer:
$0.70 per letter, $1.50 flat fee
Step-by-step explanation:
x+18y=14.1 -> x=-18y+14.1
x+35y=26

\/
(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7
|
\/
x+35(0.7)=26 -> x+24.5=26 -> x=1.5
|
\/
y=0.7
x=1.5
Hope this helps. :)
Answer:
Solution given
:total n[U]=590
customers using coupon n[C]=177
the percentage of all customers who often use coupons=177/590×100%=30%.
If n[U]=5000
no of customer using coupon be x
we have
30% of 5000=x
x=30/100×5000
x=1500
<h3>
<u>So1500 people</u><u> </u>would you expect to use a coupon if all 5,000 people in the community visited the store.</h3>
