Answer:
angle bisector theorem
Step-by-step explanation:
the angle bisector theorem tells us that if an angle is cut by a bisector than it willl be equally cut and congruent
Answer:
option (a) It will be closer to 30 than to 20
Step-by-step explanation:
Data provided in the question:
For sample 1:
n₁ = 10
variance, s₁² = 20
For sample 2:
n₂ = 15
variance, s₂² = 30
Now,
The pooled variance is calculated using the formula,

on substituting the given respective values, we get

or
= 26.0869
Hence,
the pooled variance will be closer to 30 than to 20
Therefore,
The correct answer is option (a) It will be closer to 30 than to 20
Answer:3 and 1/4 is closer to 3 and 3/5 is closer to 4
Step-by-step explanation: one is closer on the number scale then the other
Hey there!
The formula for the volume of a cylinder is
, which is essentially the base multiplied by the height.
If our diameter is six, then our radius is three, so we can solve for our base below. We will use 3.14 for pi.

Now, we multiply this by our height of four.

Therefore, our volume is 113.04 cubic units.
I hope this helps!
