Gator Brews manufactures three types of brews: A, B, and C. These brews are produced via twa production processes: 1 and 2. Running process 1 for an hour costs $400 and yields three hundred gallons of brew A, one hundred gallons of brew B, and one hundred gallons of brew C. Running process 2 for an hour costs $100 and yields one hundred gallons of brew A, one hundred gallons of brew B. To meet customer demands, at least 1000 gallons of brew A, 500 gallons of brew B, and 300 gallons of brew C must be produced daily. Gator Brews wants to minimize the cost of running both processes. Set up and answer this question in worksheet "Part 6" using the simplex method in solver. (15 points) X1-hrs of process 1 X2 - hrs of process 2 MIN Z = 400x1 +100X2 s.t. Gallons of A 300 x1 + 100 x2 1000 Gallons of B 100 x1 + 100 x2 2500 Gallons of C 100 x1 + 0x2 2 300
Answer:
z(min) = 1400
x = 3
y = 2
Step-by-step explanation:
Formulation:
Let´s call
x number of running hours of process 1
y number of running hours of process 2
Then Objective Function to minimize is:
z = 400*x + 100*y
Constrains:
Subject to
Demand constraint ( by type of brews)
300*x + 100y ≥ 1000
100*x + 100*y ≥ 500
100*x ≥ 300
General constraint
y≥0 Note that we already have x≥= (in the third constraint)
By using the on-line slver we find:
z (min) = 1400 $
x = 3
y = 2

Answer:
Quadrant 4
Step-by-step explanation:
To find this out, simply get a coordinate plane and plot the coordinate point.
OR
You can remember this formula for coordinate points:
Quadrant 1: (x,y)
Quadrant 2: (-x,y)
Quadrant 3: (-x,-y)
Quadrant 4: (x,-y)
Point (7,-10) has a positive x-coordinate and a negative y-coordinate. This means it belongs in quadrant 4.

To estimate the benefits of an SAT prep course, a random sample of 10 students enrolled in the course is selected. For each of these students, their entrance score on the exam taken at the beginning of the course is recorded. Their exit score on the exam they take at the end of the course is recorded as well. The table displays the scores.
A 3-column table with 10 rows. Column 1 is labeled student with entries 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Column 2 is labeled Before with entries 800, 870, 860, 820, 1140, 1050, 850, 910, 830, 1140. Column 3 is labeled after with entries 1100, 1010, 1000, 980, 1410, 1270, 1020, 1010, 1060, 1340.
A 98% confidence interval for the mean difference (after – before) in score is 137.04 points to 248.96 points. Based on the confidence interval, is it reasonable to claim that the SAT prep course is beneficial?
No, 0 is not contained in the confidence interval.
Yes, 0 is not contained in the confidence interval.
No, the confidence interval only contains positive values.
Yes, the confidence interval only contains positive values.
Answer:
,, yes the confidence interval only contains positive values
Answer:
Yes, the confidence interval only contains positive values.
Step-by-step explanation:
A 98% confidence interval for the mean difference (after – before) in score is 137.04 points to 248.96 points.
Based on the confidence interval if we go though the table we will find that each student show increase in confidence level .
As, At least the confidence level improved because it contains positive values only if we subtract previous value with the new values.
Therefore ,Yes, the confidence interval only contains positive values.

Courtney and Christy both leave the coffee shop at the same time, but in opposite directions. If Christy travels 9 mph faster than Courtney and after 7 hours they are 189 miles apart, how fast is each traveling?
Courtney is traveling ___________ mph.
Christy is traveling _____________ mph.
Answer:
Courtney is travelling at 9mph
Christy is travelling at 18mph
Step-by-step explanation:
Courtney's speed = x
Christy's speed = y
Christy travels 9 mph faster than Courtney: x+9=y
Distance = speed * time
Courtney's distance after 7 hours = 7x
Christy's distance after 7 hours = 7y
After 7 hours, they're 189 miles apart:
7x+7y=189
x+y=27
x+y=27
x+x+9=27
2x=18
x=9
y=x+9
y=9+9
y=18

Note: Make your final answer clear by writing 'The number is ...'
(the question is formatted a bit weird, but I'm assuming the third statement is meant to be '1/3 of the number is a square number'. If not, let me know and I'll adjust my answer accordingly)
Answer:
The number is 27
Step-by-step explanation:
Let the number be called x.
10% of x is greater than 1 but less than 7. Written mathematically, this is 1<0.1x<7. Multiply this by ten to get 10<x<70.
1/3 of x is a square number. The squares 4, 9, and 16 are the only squares that satisfy this statement, because the if the square was 1, x would be 1, which doesn't fit x>10, and if the square was 25 or higher, x would be greater than 70, which doesn't fit x<70.
x isn't a multiple of six. If the square is 4, x is 12, which is a multiple of six so this doesn't work. If the square is 16, x is 48, which is a multiple of six too, so this doesn't work. But if the square is 9, x is 27, which isn't a multiple of six and satisfies the statement.
Double check that x=27 is a valid answer.
Is 27 a whole number between 1 and 100? Yes
Is 10% of 27 greater than 1 and less than 7? Yes (10% of 27 is 2.7)
Is 1/3 of 27 a square number? Yes (1/3 of 27 is 9, which is the square of 3)
Is 27 not a multiple of 6? Yes (27 isn't divided evenly by 6)
Therefore, the number is 27.
