Hi !

I’m sorry I won’t be doing the solving for you because it should be easy but I will give you the logic in case you don’t know how to solve them...

Please look at the picture below

According to the theorem we know that DE is:

DE = 1/2 ( BC)

Solve for X then find the values.

Note: remember that if you want to make your life easy multiply both side by 2 to get rid of the 1/2.

You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can you do this?

puteri [66]

Answer:

Step-by-step explanation:

lets begin to set up this question. i personally find questions like these easiest when i begin to set up ideas to help my brain process it better, for example:

person a

person b

person c

person d

we know that each (person) must receive at least 1 candy. we also know that we have 7 candies. therefore if we want do draw this out :

person a- 1

person b- 1

person c- 1

person d -1

notice that we now have given away 4 of the 7 candies. now we have 3 candies left. we can simply:

person a- 2

person b-2

person c-2

person d- 1

but, keep in mind that there are still many more ways that we can distribute the candies to other kids. the question we are asked is how may ways can we do this. since i have already illustrated the question, you can either learn how to put this into an equation, or experiment how many variations there are. the answer, either way is 15.

According to the rational root theorem, which is a factor of the polynomial

vekshin1

Supposing 2x-7 were a factor, then 7/2 would be a root. Use synth. div. to determine whether 7/2 actually is a root:

__________________________
7/2 / 6 -21 -4 24 -35
21 0 -14 35
----------------------------------------
6 0 -4 10 0

Since the remainder is zero, 7/2 is a root and 2x - 7 is a factor.

Let E be the event where the sum of two rolled dice is even. List the outcomes in Ec (complement of E)

d1i1m1o1n [39]

We have an event E that represent the outcomes where the sum of the two rolled dice is even.

This includes all the combinations when both dices are even or both dices are odd.

We have to list the outcomes for Ec, the complement of E. This event Ec will represent all the outcomes where the sum of the two dices is odd.

All outcomes where one dice is even and the other is odd are part of Ec.

Then, we can list them as:

(1,2), (1,4), (1,6)

(2,1), (2,3), (2,5)

(3,2), (3,4), (3,6)

(4,1), (4,3), (4,5)

(5,2), (5,4), (5,6)

(6,1), (6,3), (6,5)

This represents half of the sample space. The other half corresponds to outcomes that are part of event E.

Answer: all the outcomes that correspond to Ec are (1,2), (1,4), (1,6), (2,1), (2,3), (2,5), (3,2), (3,4), (3,6), (4,1), (4,3), (4,5), (5,2), (5,4), (5,6), (6,1), (6,3) and (6,5).
