Crystal surveyed 60 people in her neighborhood to determine their favorite free-time activities. her data shows that 50% said watching television, 25% said reading, 10% said playing sports, and the rest said going to the movies. what circle graph best represents crystal’s data?

First circle graph

Step-by-step explanation:

Given: Crystal surveyed 60 people in her neighborhood to determine their favorite free-time activities.

Also her data shows that 50% said watching television, 25% said reading, 10% said playing sports, and the rest said going to the movies.

Since 50% means exactly half of people watching television and 25% means exactly one quarter of people said reading.

By matching these properties only the first circle graph represents Crystal's data.

x + 4/7

step-by-step explanation:

use cymath

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.
