Andrew, who is ill, takes vitamin pills. Each day, he must take at least 16 units of myra X, at least 5 units of myra Y, and at least 20 units of myra Z. He can choose between tablets and capsules. Each tablet contains 8 units of myra X, 1 unit of myra Y, and 2 units of myra Z, while each capsule contains 2 units of myra X, 1 unit of myra Y and 7 units of myra Z. The cost per tablet is Php15, and Php30 per capsule. How many tablets and capsules should he buy in order to minimize his cost?
Answer:
z (min) = 105
x₁ = 3
x₂ = 2
Step-by-step explanation:
Let´s call x₁ (number of tables) and x₂ ( number of capsules)
assuming it is only possible to get a whole table or capsule we have:
Table x₁ 8 u myra X 1 u of myra Y and 2 u of myra Z
Capsule x₂ 2 " 1 " and 7 u "
Objective function
z = 15* x₁ + 30* x₂ to minimize
First constraint ( Myra X )
8*x₁ + 2*x₂ ≥ 16
Second constraint ( Myra Y )
x₁ + x₂ ≥ 5
Third constraint ( Myra Z )
2*x₁ + 7*x₂ ≥ 20
General constraints x₁ ≥ 0 x₂ ≥ 0 both integers
Then the model is:
z = 15 * x₁ + 30 * x₂ to minimize
Subject to
8*x₁ + 2*x₂ ≥ 16
x₁ + x₂ ≥ 5
2*x₁ + 7*x₂ ≥ 20
x₁ ≥ 0 x₂ ≥ 0 both integers
As the constraints, all are of the form ≥ we have to subtract surplus variables sₐ and add artificial variables Aₐ
sₐ ≥ 0 Aₐ ≥ 0
The first table is
z x₁ x₂ s₁ s₂ s₃ A₁ A₂ A₃ = Cte
1 - 15 - 30 0 0 0 M M M = 16
0 8 2 -1 0 0 1 0 0 = 5
0 1 1 0 -1 0 0 1 0 = 20
0 2 7 0 0 -1 0 0 1 = 20
Using AtoZmax and after 6 iterations we find
z (min) = 105
x₁ = 3
x₂ = 2

Solve the equation. 10p -5= - 6+2p
Answer:
STEPS : 10p -5= - 6+2pArrange similar algebra given there ... which is 'p' here , Now ;
10p -5= - 6+2p
or, 10p -2p = -6+5
( NOTE : Moving to opposite side , + becomes - and - becomes + )
10p -2p = -6+5
8p = - 1
p = - 1 / 8
Answer:
[tex]\frac{-1}{8}[/tex]
Step-by-step explanation:
You balance the equation by getting rid of the variable on one side and then you get rid of the constant on the other then solve from there
10-5=-6+2p
10p-5-2p=-6+2p-2p
8p-5+5-6+5
8p=-1
[tex]\frac{8p}{8}=\frac{-1}{8}[/tex]
p=[tex]\frac{-1}{8}[/tex]
To solve the equation we put -1/8 in the p spot:
10x-1/8-5=-6+2x-1/8
-1.25-5=-6+-0.25
-6.25=-6.25
The equation = -6.25

Step-by-step explanation:
What is the equation of the line that passes through the point (-6, -2) and has a
slope of 1/6
Step 1: Determine b by using the point (-6,-2), the given slope, and the slope intercept formula, y = mx + b.
[tex]y = mx + b\\\\-2 = \frac{1}{6}(-6) + b\\\\-2 = -1 + b\\\\-1 = b[/tex]
Step 2: Now that we have b, we can determine the equation of the line.
[tex]y = \frac{1}{6}x -1[/tex]
I didn't use + (-1) because b is negative. Therefore you need to change the equation from y = 1/6x + (-1) to y = 1/6x - 1.

B. 2,097,152
C. 524,288
D. -524,288
Answer:
B
Step-by-step explanation:
The 20th term of the sequence that begins as -4,8,-16,32,...is 2097152.
What is a geometric progression?
It is a type of sequence in which all the elements have common ratio. To calculate the common ratio we apply the following formula:
Ratio=a n/ a n-1
How to solve a geometric progression?
If we carefully watch our sequence we will be able to find that it is a geometric progression because all the terms have common ratio of -2.
To calculate the 20th term we will apply the formula:
20th term =[tex]ar^{20-1}[/tex]
=-4* [tex](-2)^{19}[/tex]
=-4*-524288
=2097152
Hence the 20 th term is 2097152.

Answer:
Parallelogram
Step-by-step explanation:
Observation 1:
the sides do not have the same measure √53≠√68 so is NOT a square and NOT a rhombus
Observation 2:
the opposite sides are congruent
AB=CD=√53, and BC=DA=√68
Observation 3:
lines that have the same slope are parallel so opposite sides are also parallel
slope of AB =slope of CD =-2/7, and slope of BC=slope of DA=8/2
so we have 2 pair of sides congruent and parallel but to decide if is a parallelogram or rectangle we need to see if the adjacent sides form 90° or not
Observation 4:
lines that are perpendicular form 90° and their slope is negative reciprocal.
AB slope =-2/7 and slope of BC =8/2 so are NOT perendicular therefore is a parallelogram
A bakery has 18 large trays of bagels and 20 small trays of bagels. Each large tray holds 30 bagels and each small tray holds 15 bagels.
Which equation could be used to find n, the total number of bagels the bakery has?
18 × 30 + 20 × 15 = n
18 + 30 + 20 + 15 = n
18×30−20×15=n
18 + 30 × 20 + 15 = n

préstamo en 36 meses a un interés del 5.8%. Calcula la cantidad total a pagar
requerida del préstamo.
Answer:
El monto total a devolver por parte de Josean Hernández será de $40,227.2, y lo devolverá en 36 cuotas de $1,117.42 cada una.
Step-by-step explanation:
En tanto Josean Hernández solicitó un préstamo de $38,400, y acordó con la financiera devolverlo durante 36 meses a un interés del 5.8%, para determinar la cantidad total a pagar y el monto de cada cuota, es necesario realizar el siguiente cálculo:
(38,400 x 5.6 / 100) + 38,000 = X
2,227.2 + 38,000 = X
40,227.2 = X
40,227.2 / 36 = 1,117.42
Así, el monto total a devolver por parte de Josean Hernández será de $40,227.2, y lo devolverá en 36 cuotas de $1,117.42 cada una.

A player pays $15 to play a game in which a chip is randomly selected from a bag of chips. The bag contains 10 red chips, 4 blue chips, and 6 yellow chips. The player wins $5 if a red chip is
selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. Let the random variable X represent the amount won from the selection of the chip, and let the random variable W
represent the total amount won, where W= X - 15. What is the mean of W?
$10.50
B
$4.50
-$4.50
D
- $6.50
E
-$10.50
Answer:
C. -$4.50
Step-by-step explanation:
To find the mean of W we must first find the mean of X. So, 10/20*5+4/20*10+6/20*20=10.5
Then because mean is impacted by transformations, the mean of W=the mean of X-15=10.5-15=-$4.50
Here we need to find the expected value of the given probabilistic game.
The correct option is B: -$4.50
-------------------------------
For an event with outcomes {x₁, x₂, ...}, each one with probability {p₁, p₂, ...}, the expected value is defined as:
[tex]EV = x_1*p_1 + x_2*p_2 + ...[/tex]
Here the outcomes are:
x₁ = winning $5.
This happens if a red chip is selected, and there are 10 red chips in a bag of 20 chips, so the probability is:
p₁ = 10/20 = 1/2
x₂ = winning $10
This happens if a blue chip is selected, and there are 4 blue chips out of 20 chips, so the probability is:
p₂ = 4/20 = 1/5
x₃ = winning $20
This happens if a yellow chip is selected, and there are 6 of these in a total of 20, then the probability is:
p₃ = 6/20 = 3/10
Now we can compute the expected value:
[tex]EV = \$ 5*(1/2) + \$ 10*(1/5) + \$ 20*(3/10) = \$ 10.50[/tex]
Now if you also take in mind that you need to pay $15.00 to play, we will see that the mean of W, the amount that you won, is:
W = $10.50 - $15.00 = -$4.50
Which means that in average, you lose $4.50
