Answer:
the answer is (2,-3)
Step-by-step,-explanation:
<span>Outcome Heads Tails
Relative Frequency 0.69 0.31
so first statement is false as 69% is close to 70%.
second statement is false as heads probability is close to 70%
last 2 statements are true:
</span><span>The theoretical probability of tails is most likely 30%.
It is likely that the coin is not fair.
</span>
<span>r means radius so it can't be negative.
<=>
A = 4 pi r²
r = sqr (A / 4pi)

Answer:
(eduacted guess) 7 minutes, 30 seconds
Step-by-step explanation:
May not be correct but what I did was find the average of 6 and 9. You add the 6 and the 9 (15), then divide it by 2.
The shape looks like a box with a chunk taken out of it. So, to find the volume of the shape, let us find the volume of the hypothetical "perfect" box and then subtract the volume of the chunk.
Volume of the box = 15x6x12 = 1080 cm³
Volume of the chunk = 10x6x4 = 240 cm³
Volume of weird shape = 1080-240 = 840 cm³
Answer: 840 cm³
