Answer:
3. It is likely.
Step-by-step explanation:
Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side
<u>Then the areas covered will be as:</u>
- point 20 = πr² = S
- point 15 = π(2r)² - πr² = 3πr² = 3S
- point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
- point 5 = π(4r)² - π(3r)² = 7πr² = 7S
Total area of the dartboard is S+3S+5S+7S = 16S
The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S
The probability of scoring at least 10 points is:
As it is between 1/2 and 1, the probability is in 'likely' region
<u>So the correct answer choice is:</u> 3. It is likely
What 2 numbers muliply to get -30 and add to get 7?
-3 and 10
(x-3)(x+10) is da answer
C is answer
Answer:
(0.5, 1)
Step-by-step explanation:
The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:
Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:
The answer is thus (0.5, 1).
5) To find the answer we can set up a proportion (see image 1), then solve for x. 5 x 1000/100 = x
x = 50
The answer is 50. :)
7) Set up another proportion (see image 2), then solve for x again.
100 x 100/25 = x
x = 400
Hope this helps! :)
