Answer:
The AILP for management to decide how many classes should be scheduled for each subject daily is
The objective function is mathematically represented as
[tex]M = P_c * a + P_w * b[/tex]
=> [tex]M = 720 a + 300 b[/tex]
Now the first constraints to this functions is
[tex]t_c * x + t_w * y \le t_a[/tex]
=> [tex] 7.5 x + 3 y \le 56[/tex]
Another constraints to this function is
[tex]k x + u y \le N[/tex]
=> [tex]6 x + 2 y \le 100[/tex]
Here x and y are the number of classes
Step-by-step explanation:
From the question we are told that
The time required for each ITC class is [tex]t_c = 7.5 \ hours[/tex]
The profit of each ITC class is [tex]P_c = \$ 720[/tex]
The time require for CWP class is [tex]t_w = 3 \ hours[/tex]
The profit for CWP class is [tex]P_w = \$ 300[/tex]
The total time available is [tex]t_a = 56 \ hours / day[/tex]
the maximum number of trainee that can be accommodated in a daily basis is [tex]N = 100[/tex]
The class size limit for ITC is [tex]k =6[/tex]
The class size limit for CWP is [tex]u =12[/tex]
Generally the aim of Hi-Tech is to maximize profit
So the objective function will be a function that maximizes profit
Generally the objective function is mathematically represented as
[tex]M = P_c * a + P_w * b[/tex]
=> [tex]M = 720 a + 300 b[/tex]
Now the constraints to this functions are
[tex]t_c * x + t_w * y \le t_a[/tex]
=> [tex] 7.5 x + 3 y \le 56[/tex]
Another constraints to this function is
[tex]k x + u y \le N[/tex]
=> [tex]6 x + 2 y \le 100[/tex]
Here x and y are the number of classes

The perimeter, P, of a square whose side length is n.
Answer: p = 4n
Step-by-step explanation:
To find the perimeter of a shape, you need to add the length of the 4 sides. A square's 4 sides are equal. Therefore, you add n+n+n+n which is the same as 4n.
Answer:
P = n4
Step-by-step explanation:
in order to find the perimeter of an object you must add up all the sides. since we are dealing with a square all the sides are n. so in conclusion, 4 times n would you get you the perimeter, P.
If M is the midpoint of AB and AM = 3x -1 and AB =5 x + 2, find x, AM, MB, and AB.
AB = 2x + 3
Just subtract the 3x - 1 from 5x + 2 = 2x + 3 is AB
x = 2
AB = 12
MB = 7
AM = 5

Annabel wants to buy a $50.00 jacket that is marked 30% off. What is the final cost of the jacket (after the discount)?
Question 1 options:
$15.00
$35.00
No Solution
$65.00
Answer:
$ 35.00
Step-by-step explanation:
50.00 ÷ 10 = 5.00 (10%)
5.00 x 3 = 15.00 ( 30%)
50 - 15 = 35.

What is the equation of the line in slope-intercept form? the line perpendicular to y = x + 2 through (-7, -8)
Answer:
[tex]y=-x-15[/tex]
Step-by-step explanation:
Point-slope formula: [tex]y-y_1=m(x-x_1)[/tex], where [tex](x_1, \ y_1)[/tex] are the coordinates of a point on the line, and [tex]m[/tex] is the slope of the line.
You are given a point that the line you are trying to find passes through, and a slope. The slope is less obvious than the point, but you can find the slope using the given information.
The line perpendicular to y = x + 2 will have the opposite reciprocal slope of this line. The slope of y = x + 2 is 1, so the opposite reciprocal of 1 is:
[tex]m=-\frac{1}{1} =-1[/tex]Now that you have both a point and the slope of the line you are trying to find, you can substitute these values into the point-slope formula (Notice: the name of this formula contains both "point" and "slope").
Substitute [tex](-7, \ -8)[/tex] for [tex](x_1,\ y_1)[/tex] and [tex]m=-1[/tex] into the point-slope formula.
[tex]y-(-8)=-1(x-(-7))[/tex]Simplify this equation.
[tex]y+8=-1(x+7)[/tex]Distribute -1 inside the parentheses.
[tex]y+8=-x-7[/tex]Subtract 8 from both sides of the equation.
[tex]y=-x-15[/tex]This line is in slope-intercept form ([tex]y=mx+b[/tex]), so we are done.

Maggie bought a pound of bananas and 4 boxes of cereal for $10.11. If each box of cereal cost $2.40, what was the price of a pound of bananas?
$0.51
$0.61
$1.51
$2.91
Answer:
$0.51
Step-by-step explanation:
If each box of cereal is $2.40, $2.40 multiplied by 4 is $9.60. $10.11 is the total, so $10.11 - $9.60 = $0.51.
Answer:
$0.51

g The average lifespan for a certain type of vehicle is 8 years and follows an exponential distribution. A lot contains 200 of these vehicles, brand new. What is the probability that 50 or more of them fail in the first 2 years
Answer:
The probability is [tex]P(A \ge 50 ) = 0.14321[/tex]
Step-by-step explanation:
The average life span is [tex]\pi = 8[/tex]
The sample size is n = 200
Generally we are told that average lifespan for a certain type of vehicle follows an exponential distribution
i.e
[tex]X \~ \ \ \ exp(8)[/tex]
Gnerally the probability distribution function for exponential distribution is
[tex]f(x) = \left \{ {{\lambda * e^{-\lambda * x }\ \ \ x\ge 0 } \atop {0 \ \ \ \ \ \ \ \ \ \ x < 0}} \right.[/tex]
Now [tex]\lambda[/tex] is the constant which is evaluated as
[tex]\lambda = \frac{1}{\pi}[/tex]
=> [tex]\lambda = \frac{1}{8}[/tex]
=> [tex]\lambda = 0.125[/tex]
Generally the that the vehicles will fail in less than 2 years is mathematically represented as
[tex]P(X \le 2 )= p= \int\limits^2_0 {\lambda e^{- \lambda * x} } \, dx[/tex]
[tex]P(X \le 2 )= p= [ {0.125 * - \frac{1}{0.125 } e^{- 0.125 * x} } ]|\left 2 } \atop {0}} \right.[/tex]
[tex]P(X \le 2 )= p= [ {0.125 * - \frac{1}{0.125 } e^{- 0.125 * 2} } ] - [ {0.125 * - \frac{1}{0.125 } e^{- 0.125 * 0} } ][/tex]
[tex]P(X \le 2 )= p= -0.77880 + 1[/tex]
[tex]P(X \le 2 )= p= 0.2212[/tex]
Generally the probability that the vehicle will fail in the first 2 years follows a binomial distribution with the mean evaluated as
[tex]\mu = n * p[/tex]
=> [tex]\mu = 200 * 0.2212[/tex]
=> [tex]\mu = 44.24[/tex]
The standard deviation is
[tex]\sigma = \sqrt{np(1 - p)}[/tex]
[tex]\sigma = \sqrt{200 * 0.2212 (1 - 0.2212)}[/tex]
[tex]\sigma = 5.86[/tex]
Using normal approximation of binomial distribution the probability that 50 or more of them fail in the first 2 years is mathematically represented as
[tex]P(A \ge 50 ) = 1 - P(A < 50 )[/tex]
Applying continuity correction
[tex]P(A \ge 50.5 ) = 1 - P(A < 50.5 )[/tex]
Here
[tex]P(A < 50.5 ) = P(\frac{A - \mu }{\sigma} < \frac{50 - 44.24}{5.87} )[/tex]
Generally
[tex]\frac{A - \mu }{\sigma} = Z (The \ standardized \ value \ of A )[/tex]
=> [tex]P(A < 50.5 ) = P( Z < 1.0664 )[/tex]
From the z-table the probability value of ( Z < 1.0664 ) is
[tex]P( Z < 1.0664 ) = 0.85679[/tex]
So
[tex]P(A \ge 50 ) = 1 - 0.85679[/tex]
=> [tex]P(A \ge 50 ) = 0.14321[/tex]

ve spent the whole weekend grading math assignments. I graded 30 students
work this weekend, which is 40% of my class. How many students do I have in
my class?
Answer:
75
Step-by-step explanation:
How many students is 1% of the class, 30/40=0.75, so you could do 0.75x100=75, or you could do 0.75x60=45, and 45+30=75.

Answer:
[tex] x = 17 [/tex]
Step-by-step explanation:
[tex] 2x + 7 = 3x - 10 [/tex] (alternate exterior angles are congruent when a transversal cuts across two straight lines)
[tex] 2x - 3x = -7 - 10 [/tex] (collecting like terms)
[tex] - x = -17 [/tex]
[tex] \frac{-x}{-1} = \frac{-17}{-1} [/tex] (dividing both sides by -1)
[tex] x = 17 [/tex]

Michelle has a piece of yarn measuring 7 yards. How many 1-inch strips can be cut from the yarn?
Answer:
252
Step-by-step explanation:
7 yards is equivalent to 252 inches.
Answer:
252 inches
Step-by-step explanation:
There are 3 feet in 1 yard. Multiply 7 yards x the 3 feet in each 1 yard.
You should now have 21 feet.
Multiply 21 feet x the 12 inches in each foot.
You should come up with 252 inches as your final product.
