22 because, since they had $8 remaining, you add the $3 so that’ll equal 11, and then since they used 1/2 of their money, $11 plus 11 is 22.
Answer:
21378
Step-by-step explanation:
The confidence level is 90%, which gives us a Z of 1.645.
Our equation is (Z^2*p*q)/e^2
(1.645^2*p*(1-.21))/ (.01^2)
E is the error proportion, .01
Q is 1-p or the proportion
P is the pop you need
With this, we can solve
and get p = 21377.5975 and rounded to 21378
Sin 45=x/s
s=x/sin 45
s=x√2
sin 60=s/12√6
(√3/2)(12√6)=x√2
(18√2)/√2=x
x=18
