The formula to solve the area for all triangles is Area= Base x Height or A=BxH.
Answer:
231.07 in^2
Step-by-step explanation:
The radius of the semicircle is 14/2 = 7 in
22x14 - 3.14x(7^2)/2 = 231.07 in^2
Answer:
4 Units
Step-by-step explanation:
Answer:
Step-by-step explanation:
here you go,
1st Step - Find the mean (average):
245 + 300 + 325 + 465 + 100 = 1435
1435/5 = 287 ( mean)
2nd step find the sun of the sqaure the difference between the gievn data and the mean
287 - 245 = 42^2 = 1,764
300 - 387 = 13^2 = 169
325-287 = 38^2 = 1,444
465 - 287 = 178^2 = 31,684
287 - 100 = 187^2 = 34,969
1,764 +169 + 1,444 + 31,684 + 34,969 = 70,030
Now divide that by the number of samples minus 1 ( 5-1=4)
70,030 / 4 = 17,507.5
The variance = 17, 507.5
