There are 16 girls and 18 boys in a class. The teacher chooses a student's name at random to answer a question. What is the probability that the teacher chooses a girl to answer the question?
A
1
34
O
B.
16
OO

8/17

Step-by-step explanation:

16 girls and 18 boys in a class

Total number of students:

16 + 18 = 34

Probability of choosing a girl:

P(g) = number of girls / total numberP(g) = 16/34 = 8/17

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
