//I take it you're trying to find the area or circumference of a circle, so I'll do both.
= area
3.14 * <span>
= 28.26 (2 d.p)
</span>2
r = circumfrence
<span>2 * 3.14 * 3 = 18.84 (2 d.p)</span>
Answer:
Probability = 1 / 5
Step-by-step explanation:
Assuming that rates are from 1 to 5 ; with equal probability of being 1, 2 , 3 , 4, 5 each.
So, probability of 3 stars = Outcomes with 3 stars / Total outcomes
= 1 / 5
Work shown above! Answer would be C (3rd option)
Answer:
O 9
Step-by-step explanation:
Subtracting a negative turns it into addition. So this becomes 20 + 3 - 10 - 6 + 3 + 2 - 3.
Going through this problem looks like this: 23 - 10, 13 - 6, 7 + 3, 10 + 2, 12 - 3. And you get 9.
