Answer:
18 inches
Step-by-step explanation:
formula is V = π* r^2* h/3.
h = 21. 21/3 = 7.
7*3.14 = 21.98.
1,780.38/21.98 = 81.
√81 = 9.
r = 9
d = 2r
9*2 = 18 inches.
I believe the answer is 0.2105 and the error you made of saying 0.4209 was because you did a 2-PropZTest when this question seems to be asking for one proportion (not two). When the p value is greater than or less, use one-proportion, if it is "!=" not equal than it is two-proportion. Please let me know if this was correct.
Answer:
B. x ≤ 1 or x > 6
Step-by-step explanation:
Subtract 8 and divide by 2. (Same steps for both inequalities.)
2x +8 ≤ 10
2x ≤ 2
x ≤ 1
__
2x +8 > 20
2x > 12
x > 6
The solution is x ≤ 1 or x > 6.
Answer:
x = 4
Step-by-step explanation:
180° - 114° = 66°
15x - 6 = 66
15(4) - 6 = 66
60 - 6 = 54
Statement is wrong because we can see another angle. so...
Final answers: x = 4 while 54 + 114° = 168° then 180° - 168° = 12°
