Does anyone know the answer to this problem??

20 of the 120 don’t take either. This means 100 students take French, Spanish or both.

The total taking a language is 53 + 68 = 121

A) 131 -100 = 21

There are 21 students taking both French and Spanish

B) 53-21 = 32 take Spanish only.

32 / 120 students = 4/15 probability

none cuz there are no "following statements" regarding the question

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
