Answer:
Step-by-step explanation:
From the given information:
Total number of students,
The choices were: Chess(C), Swimming(S), and Football(F).
Everyone liked at least one sport except 7 kids,
Chess is not an active sport; and
10 children liked Chess only,
The probability that a randomly-chosen child from this group does not like active kinds of sport is the Probability that a student plays chess only or like no kind of sport at all.
The base is 30.
Hopefully I got this correct, not 100%
50, 66, 73, 74, 75, 75, 76, 76, 81, 81
Remember, the range is when you subtract the lowest number from the highest number :)
Range : 81 - 50 = 31
Remember, the median is the middle number of an ordered data set from least to greatest.
Median : 75
Remember, the mode is the number that is on there the most.
Mode : 75, 76, 81 are all considered to be modes. However, if that is not one of the answer options, then your answer would be : There are not modes.

Step-by-step explanation:
Answer:
Therefore it will take s for the object to reach the ground.
Step-by-step explanation:
Given function is
H(t) = -64 t²+169.
where H is height in feet, and t is time in second.
When the object touches the ground, the height of the object will be zero.
i.e H(t) = 0.
Therefore
H(t) = 0
⇒ -64 t²+169=0
⇒ -64 t²= -169
[ square root both sides]
Time can not be negative.
Therefore
Therefore it will take s for the object to reach the ground.
