Step-by-step explanation:
P(BorL)=(2/8)+(1/8)=(3/8)
He is expected to wear boots or loafers in the next 264 days
264(3/8)=99 of those days
Answer:
b=2
c=-24.01
Step-by-step explanation:
If I understood your question right you need to find the constants b and c in the polynomial:

such that:

In order to get a system of two equations you can find limes when x goes to 4 from the right side or from the left side.
I solved this using a number that is close to 4. When it goes from right I used 4.1 and from left 3.9. This way you get two equations:

When you solve the system you get the answers above.

Step-by-step explanation:
(it's a system)
4x+3y=615
x+y=180
(system as well)
4x+3y=615
x=180-y
4(180-y)+3y=615
720-4y+3y=615
-y=-105
y=105
x+105=180
x=180-105
x=75
