Answer:
0.77 and 0.06
Step-by-step explanation:
Relative frequency basically means the probability that a random student does it. In the first question's case, there are 42 + 22 = 64 students who drive or ride the bus to school that are juniors, and the total number of juniors is 83, yielding 64 ÷ 83, which is about 0.77.
Repeating the same process, there are 11 seniors who walk to school out of a total number of 182 students. Therefore, 11 ÷ 182 gives us approximately 0.06

Step-by-step explanation:
the formulas can be easily found on the internet.
remember, the diameter of a circle is 2 times the radius.
so, the radius of our circle here is 4/2 = 2 cm.
circumference :
2×pi×r = 2×3.14×2 = 12.56 cm
area :
pi×r² = 3.14×2² = 3.14×4 = 12.56 cm²
hey, your teacher gave you the circle, where the circumference and the area have the same quantity ! funny !
so, make double sure you use the correct unit dimensions (remember, a distance has only one dimension, an area has 2 dimensions, and a volume has 3 dimensions).
Just plug in the square root of 100 in your calculator (10) and then either leave it as 10/49 or simplify it to a decimal...depending on what your teacher is expecting from you.
