Answer:
and 
Step-by-step explanation:
The number of people is 
and the number of hours they are present in the space is 
.
Per person entry cost is $8.
Per hour cost of rent is $40.
They plan to earn a minimum of $600.
Donations by all the people entering the space is 
Total cost of renting the space is 
which will be subtracted from the total amount of donations.
The inequality that represents the situation is and .
4 the first one it would be 1/5 or 2/10 and the second one would be 4/5 or 12/15 Ana the third one would be 3/or 1/2
X + y = 3
2x + 4y = 8
This is a system of equations. You can solve it using elimination. Start by multiplying the top equation by -2.
(x * -2) + (y * -2) = (3 * -2)
-2x - 2y = -6
Now add that and the bottom equation. This will cancel out x.
-2x - 2y = -6
+ 2x + 4y = 8
-----------------------
2y = 2
Solve for y.
2y = 2
y = 2/2
y = 1
Now plug 1 in for y in the first equation.
x + y = 3
x + 1 = 3
Solve for x.
x + 1 = 3
x = 3 - 1
x = 2
So x = 2 and y = 1.
Subtract the mean from Jake's score:
520 - 500 = 20
Divide by the standard deviation:
20/60 = 0.33
Jake scored 0.33 standard deviation above the mean.
From the Z-table, 0.33 = 0.6293 = 62.93% of students scored below Jake.
Round to 63%
