Will give brainliest a spinner is divided into four equal sections labeled a, b, c, and d. a deck of cards has 10 cards, numbered 1 through 10. if the spinner is spun once and then a card is drawn, how many possible outcomes contain a b and an even number?

Step-by-step explanation:

There are 4 equal section A, B, C, D and each contains 10 cards from number 1 to 10. In total there are 40 cards.

From number 1 to 10, there are 5 even numbers.

They are 2, 4, 6, 8, 10.

These are the only 5 outcomes that can be get.

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.
