Cos(60) = cos(90 - 30) = sin(30) = 1/2
This should be what you want.
This question is impossible to solve.
this is why:
if 4x-4=0
then x=1
so if 8x + 4 = 8
then x is false.
I get these question quite a lot in my GCSEs.
you have to prove why they are fake.
Answer:
Step-by-step explanation:
Given that a survey was conducted that asked 1004 people how many books they had read in the past year.
Results are:
x bar =12.5
s = 16.6
n = 1004
Std error of sample = 
Since population std dev is not known t critical value can be used for confidence interval.
df = 1004-1 =1003
t critical = 1.96
Margin of error 
Confidence interval lower bound 
Upper bound
Answer:
It would be $62.62 because basically you want to do 52.50 times 1.25
Answer:
(5,-2)
