When asked to factor the trinomial 6x^2-18x+12, a student gives the answer (x-2)(x-1). what is one thing wrong with this answer? a. there is nothing wrong with the answer b. 6 is also a factor of this trinomial c. the factors are not simplified d. the minus signs should be plus signs

B. 6 is also a factor of this trinomial.

Step-by-step explanation:

We have been given a trinomial . A student gives the answer (x-2)(x-1).

To figure out student's mistake, let us factor our given trinomial by splitting the middle term.  

Therefore, 6 is also a factor of our given trinomial and option B is the correct choice.

b) 36

step-by-step explanation:

18 times 2 is 36

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
