If two events are disjoint (i.e. mutually exclusive) they cannot both occur and so we can determine probabilties by simple addition:

P(AorB)=P(A)+P(B) 
P(AorB)=\frac{40}{61}+\frac{2}{61} 
P(AorB)=\frac{42}{61} 
P(AorB)\approx 68.8\% 

A more complete answer would use a joint probability table but that's difficult to type out/format correctly here.

Answer:

a. earned: $292.50

b. total: $2,092.50

Step-by-step explanation:

A = 1800 [1 + (0.065 * 2.5)] = 2092.5

A = $2,092.50

To find the amount is earned, subtract the total with how much to started with

2,092 - 1,800 = 292.50

Help out please thank you

Answer:

x = 26

Step-by-step explanation:

The three angles form a straight line, so they will sum to 180

4x - 8  + 34  + 76- x = 180

Combine like terms

3x+ 102 = 180

Subtract 102 from each side

3x+102-102 = 180-102

3x= 78

Divide each side by 3

3x/3 = 78/3

x = 26

I have a project, im gonna have to teach someone how M and B in the equation y=mx+b affect the equation of the line.
Luba_88 [7]
Y = mix + b would be slope intercept for. your y intercept would be B which is the line that crosses that y intercept your Mx would be a fraction for point slope form like if your slope would be 1 over 2 you would fo up and left twice because of rise over run
