Answer:
P(B and V)=10%
Step-by-step explanation:To solve this poroblema we use the formula of combinations:
C(n,r)=(nr)=n!(r!(n−r)!)
Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:
5C2= 
5C2=10
The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:
2C2=1
Then the probability is:
P( B and V)= 
=0.1= 10%

The slope equals to 4
By rearranging the equation to be this : y=4x-5.5

Step-by-step explanation:
So here are 4 rules when it comes to exponents:
- When you raise a power to a power, you really just multiply the exponents:

- When you multiply 2 exponents of the same base, you add the exponents together:

- When you divide 2 exponents of the same base, you subtract the exponents:

- To convert a negative exponent into a positive one, flip it to its reciprocal:

<u>Part A:</u>

<u>Part B:</u>

<u>Part C:</u>
