The two lines intersect at point B, hope this helps.
Answer:
z=3
Step-by-step explanation:
4(z+6)-11=25
add 11 to both sides
4(z+6)-11+11=25+11
simplify
4(z+6)=36
divide each side by 4
(4(z+6))/4=36/4
Simplify
z+6=9
subtract 6 from each side
z+6-6=9-6
simplify
z=3
From the information given:
Random wins 2000 800 400 0
Probabilities 1/10^4 4/10^4 10/10^4 9985/10^4
thus the expectation will be:
E(x)=[2000+4*800+4000+9985*0]/10^4
E(x)=9200/10000
E(x)=$0.92
Answer:
e=3 d=2
e=7 d=3
e=11 d=4
e=15 d=5
Step-by-step explanation:
all you have to do is solve for the d by substituting the value of e into the equation.
Answer:
For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.
Step-by-step explanation:
For example, x > 2 would have an open circle and you are NOT including the 2 that is inputted.
For x
6, it would have a closed circle and you ARE including the 6 that is inputted.
