Answer:
The probability that a student earns a grade of A is 1/7.
Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:
P(E) = n(E) / n(S)
As the total number of students = n(S) = 35
Students getting the grade A = n(E) = 5
So, the probability that a student earns a grade of A:
P(E) = n(E) / n(S)
= 5/35
= 1/7
Hence, the probability that a student earns a grade of A is 1/7.

Answer:
Option (B) 5.1 units
Step-by-step explanation:
Since the radius of the circle is half of its diameter and given the diameter of the circle is 10.2 units then the radius would be
Thus the answer.
Answer:
$168
Step-by-step explanation:
1. x - 1/4x = 126
2. multiply each side by 4
3. 4x - x = 504
4. 3x = 504
5. divide each side by 3
6. x = 168
It would be a great idea to narrowing it down to (2^3)^134 mod 5. now it is easier cause <span> 8 = 3 (mod 5), let's compute 3^402 (mod 5).
</span><span>3^4 = 81 = 1 (mod 5). </span>
<span>Therefore, 3^402 = (3^4)^100 * 2^2 = 1^100 * 4 = 4 (mod 5). </span>
