Answer:
-3
Step-by-step explanation:
First - change the equation to y=mx+b format
3y/3 = 4x/3 - 17/3
y = 4/3x - 17/3
Second - then (2,y) plug x = 2
Third - solve
y = 4/3(2) - 17/3
y = 8/3 - 17/3 = -9/3 = -3
Answer:
Use Pythagorean theorem,
Hypotenuse² = base² + altitude²
= 3²+ 6²
= 9 + 36
x² = 45
x = √45
x = 6.71
Step-by-step explanation:
Answer:
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
is the estimate
z is the zscore that has a pvalue of 
, also called the critical value.
The standard error is:
90% confidence level critical value
So 
, z is the value of Z that has a pvalue of 
, so 
.
Estimate:
72 petty theft cases and finds 45 of these have gone unsolved.
So 
Standard error:
