STELLE
A skating rink attendant monitored the number of injuries at the rink over the past year. He tracked the ages of those injured
and the kinds of skates worn during injury. The probability that an injured skater was age 12 is 0.141, the probability that an
injured skater was wearing roller skates is 0.701, and the probability that an injured skater was age 12 and was wearing roller
skates is 0.108. What is the probability that a randomly chosen injured skater was age 12 or was wearing roller skates?

the answer will be

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

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.
