567 square mm
because 27*7 is 189 an times 3 because each side has 3 sides so it equals to 567 square mm! :)
Answer: 2.508
Step-by-step explanation:
As per give , we have
Sample size : n= 23
Degree of freedom : df= n-1=22
significance level :
Since , the sample size is small (n<30) and population standard deviation is unknown.
So , we use t-test.
For confidence interval , we find two-tailed test value.
Critical t-value :
[using students's t-critical value table]
Hence, the critical value that should be used in constructing the confidence interval = 2.508
Answer:
Step-by-step explanation:
The length of the ramp is computed with the help of the following trigonometric function:
Answer:
1/6 because you would change 1/3 to 2/6 and then divide that in half.
