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
The answer is definitely false
Look ar the picture.
Your answer: 2 lines of symmetry.
Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
468.
Triangles=108
Base=120
Back=90
