Can someone answer this question please answer it correctly and please show work please help me if it’s correct I will mark you brainliest

3/7

Step-by-step explanation:

There are 39 swimmers. To find the probability we must put 39 over the total amount of students on each winter sports team.  50 + 39 + 1 + 1 =  91.

Now solving we get 39/91  simplified as 3/7 as our final answer and the probability that the athlete is a swimmer.

3/7

Step-by-step explanation:

Step 1:  Find the total amount of people

50 + 39 + 1 + 1

91

Step 2:  Find the probability of a swimming team

swimming / all

(39/13) / (91/13)

3/7

 3/7

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.
