Answer:
50.29 in^2
Step-by-step explanation:
From the circumference we need to find the radius.
Since C = 2*pi*r, r = C / (2*pi).
Here, with C = 25  1/7 in, r = (25  1/7 in) / [ 2(22/7) ], or r = 4 in
The area of the cake is A = pi*r^2, or (here)  A = (22/7)(4 in)^2 = 50.29 in^2
 
        
             
        
        
        
Answer:
 
So the answer for this case would be n=107 rounded up to the nearest integer
Step-by-step explanation:
Information given
 the sample mean
 the sample mean
 the sample deviation
 the sample deviation
 the sample size
 the sample size
Solution to the problem
The margin of error is given by this formula:
 (a)
    (a)
And on this case we have that ME =0.001 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
 (b)
   (b)
We can use as estimator of the real population deviation the sample deviation for this case  / The critical value for 99% of confidence interval is given by
/ The critical value for 99% of confidence interval is given by  , replacing into formula (b) we got:
, replacing into formula (b) we got:
 
So the answer for this case would be n=107 rounded up to the nearest integer

Answer:
89°
Step-By-Step Explanation:
<WYT is the angle 4
<UYW is the angle 5
since angle 4 and 5 are on the same line and 
anngle 4 is 91°,
180° - 91° = 89°
This shows that <UYW is 89°

Answer: You plug in a value for one of the variables
Step-by-step explanation: For example f(x)=2x+2
x=6 2(6) +2=14
