Answer:
A
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.
Option B:
The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.
Solution:
Given expression: 
To find the equivalent expression for the given expression.
Apply absolute value rule:
<em>If |x| ≤ m then -m ≤ x ≤ m.</em>

⇒ -5 ≤ a ≤ 5
⇒ -5 ≤ a and a ≤ 5
Switch the sides, we get
⇒ a ≥ -5 and a ≤ 5
The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.
Option B is the correct answer.
1/4 =2/8+3/8 =5/8
1-5/8=3/8
