Answer:
Step-by-step explanation:
The city contributed $13,500; the county contributed $27,000; and the state contributed $54,000.
Let x be the amount the city contributes. Since the county contributes twice as much as the city, the county's amount is 2x. Since the state contributes twice as much as the county, the state's amount is 2(2x) = 4x.
They total 94,500:
x+2x+4x = 94500
7x = 94500
Divide both sides by 7:
x = 13500
2x = 27000
4x = 54000
Answer:
yes
Step-by-step explanation:
youre trying to find when -1/4x + 3/2 = -x+ 3
so if you set it up like that and then solve for x you get 2
then, you know that 2 is your x value so just plug in x into one of the equations to get the y value
(i used -x+3 bc its easier)
-2+3=y
y= 1
so your solution is (2,1)
also heres the graph
(a) without replacement:
P(S)=13/52=1/4
P(SS)=(1/4)*(12/51)=1/17
Probability of selecting two spades without replacement is 1/17.
(b) with replacement
P(S)=13/52=1/4
P(SS)=(1/4)(13/52)=1/16
Probability of selecting two spades with replacement is 1/16.
-1.43*0.11= -0.1573
That should be it
