Question

Answer 2

PLEASE HELP!!!!!

Answer 3

FIRST-write your given values.

Answer 4

Chance(probability that Katie with get married) = 72% (or 72/100)
Chance (probability that Katie will graduate) = 46 % (or 46/100)

Answer 5

60/100 (probability that Katie will get married and graduate)=60%

Answer 6

SECOND -->Write your unknown-what you want to solve for.

Answer 7

i want to solve for the chances she'll either graduate or get married
so if 72% is married
and 46% is graduate

Answer 8

Yes-you are solving for the chance/probability Katie will get married OR the chance/probability that she will graduate.

Answer 9

THIRD-what RULE can you use to solve this problem?

Answer 10

empirical rule?

Answer 11

Hint-it is one of the PROBABILITY rules.

Answer 12

Probability that one OR another event will occur =

Probability of desired event #1 occurring + Probability of desired event #2 occurring

Answer 13

so its adding the married and graduate together

Answer 14

hello?

Answer 15

Yes-correct.

Answer 16

72+46

Answer 17

The total probability must never exceed 100%......... YOU MUST USE A SECOND RULE HERE:

When two events, #1 and #2, are not mutually exclusive (they can occur at the same time), there is some overlap between these events.........so---------->

[The probability that either event #1 OR event #2 will occur] =



[Probability of desired event #1 occurring + Probability of desired event #2 occurring] - [THE PROBABILITY THAT BOTH EVENT #1 AND EVENT #2 WILL OCCUR]

Answer 18

So apply the above rule using your final GIVEN - the one you provided above:

probability that Katie will get married and graduate)=60%

Answer 19

76+42-60

Answer 20

Yes-awesome!

Answer 26

hey can you help with more question please

Answer 27

[7] Find the radian measure for 2100 and its associated coordinate point on the unit circle. Then find the sin, cos, and tangent.

210(π/180) = 7 π/6 radians
Notice the 210 degrees brings ( - v3/2, -1/2)
The Sin=y/rad = -1/2 / 1 = -1/2 =
The Cos=x/rad = -v3/2 / 1 =
The Tan=y/x = -1/2 /-v3/2 = -1/ v3 =

I am not sure how to do this one-sorry!
