Answer: C
Step-by-step explanation:
Answer:
0.06 = 6% probability of landing open side up.
0.14 = 14% probability of landing closed side up.
0.8 = 80% probability of landing on its side.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these numbers are taken from previous trials.
Landing open side up:
3 out of 50, so:

0.06 = 6% probability of landing open side up.
Landing closed side up:
7 out of 50, so:

0.14 = 14% probability of landing closed side up.
Landing on its side:
40 out of 50, so:

0.8 = 80% probability of landing on its side.
Answer:
A
Step-by-step explanation:
Answer:
39.27
Step-by-step explanation:
Calculate whole area of circle - pi5^2 = 78.54
Divide answer by 2 as only half of the circle is shaded - 78.54/2 = 39.27
Answer:
B. (-2,-4)
Explanation
Given equations:
y = 3x + 2
y = -2x - 8
Solving both equations will yield the values of x and y;
Solution:
y = 3x + 2 ----- (i)
y = -2x - 8 ------ (ii)
Using substitution method, input equation i, into ii
3x + 2 = -2x - 8
Collect like terms and solve;
3x + 2x = -8 -2
5x = -10
x = -2
Then put x = -2 into i, to find y
y = (-2 x 3) + 2
y = -6 + 2 = -4
So, the solution of the equation is B. (-2,-4)
