Answer:
188 meters cubed
Step-by-step explanation:
- radius = 1/2d d=6 radius =3 height 20
- formula for thia equation is 1/3 (3.14)(3^2)(20)
- (3.14)(9)(20)
- 3.14 x 9 = 28.26
- 28.26 x 20 = 565.2
- 565.2/3 = 188.40
- 188.4 round to 3sf is 188
Answer:
-3y < -2/5
Step-by-step explanation:
Multiplied means times
-3y
is less than means <
-3y < -2/5
2z^7
-3--5=2. z^7
Since both have the same exponent
The first answer y to the second power + z to the second power = x to the second power
The range rule of thumb is that the range is four times the standard deviation. The range in this case is 922 cubic cm to 1496 cubic cm, i.e., 574 cubic cm.
Therefore, according to the rule, the standard deviation is 574 cubic cm/4 =
143.5 cubic cm. The actual standard deviation is 161.7 cubic cm. The difference is 161.7 - 143.5 = 18.2. Since this is greater than 15 cubic cm, the rule in this case is not accurate.
