Agroup of students were surveyed to find out if they like bike riding and/or roller skating as a hobby. the results of the survey are shown below: 80 students like bike riding 20 students like bike riding but do not like skating 90 students like skating 40 students do not like bike riding make a two-way table to represent the data and use the table to answer the following questions. part a: what percentage of the total students surveyed like both bike riding and skating? show your work. (5 points) part b: what is the probability that a student who does not like bike riding also does not like skating? explain your answer. (5 points)

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

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
