1. in a poll of students at the basketball championship, 82% of the students say that basketball is better than football.
(a) explain why it is not a valid conclusion to say that basketball is more popular than football at the school.
(b) suggest a better method of determining which sport is more popular.

Step-by-step explanation:

The conclusion is not valid because here sample is drawn from those who are at the basketball championship.

OBviously these students will prefer basketball to football and hence sample is not randomly drawn.

If instead general group of students is surveyed this would have given a more reliable answer.

b) A random sample covering all students including students not at the basketball championship should have been included to get a better reliable conclusion.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
