What is linear programming problem?
The goal of the Linear Programming Problems (LPP) is to determine the best value for a given linear function. The ideal value may be either the highest or lowest value. The specified linear function is regarded as an objective function in this situation. The objective function may have a number of variables that must meet a set of linear inequalities known as linear constraints. These variables may also be subject to conditions. The following scenarios, such as manufacturing difficulties, diet problems, transportation challenges, allocation problems, and so on, can be solved optimally using the linear programming problems.
After first iteration,
Negative minimum Z_j-C_j is -2 and its column index is 1. So, the entering variable is x_1.
Minimum ratio is 1 and its row index is 2. So, the leaving basis variable is S_2.
∴ The pivot element is 2.
Entering =x_1, Departing =S_2, Key Element =2
After second iteration:
Since all Z_j-C_j≥0
Hence, optimal solution is arrived with value of variables as :
x_1=1,x_2=0
Max Z=2

A line with a slope of -7/16 passes through the point (-16, 7). What is its equation in
slope-intercept form?
Answers
A equation of line with a slope of -7/16 passes through the point (-16, 7) is y = (-7/16)x
We know that the formula for the slope-point form of equation of line:
(y - y1) = m(x - x1)
Let (x1, y1) = (-16, 7)
and slope m = -7/16
Using above formula,
(y - 7) = (-7/16)(x - (-16))
y - 7 = (-7/16)(x + 16)
y = -7/16x - 7 + 7
y = (-7/16)x
This equation is slope-intercept form (y = mx + c) with slope -7/16 and y-intercept 0.
Therefore, a equation of line with a slope of -7/16 passes through the point (-16, 7) is y = (-7/16)x

The mean of the number of plants (d) increases by 5.5
How to compare the mean of the number of plants?From the question, we have the table of values that can be used in our computation:
In the table, we have the following rows
Plants and Number of tomatoes
The mean of the number of plants is calculated as
Mean plant = Total number of tomatoes/Total number of plants
For the four plants, we have
Total number of tomatoes = 31 + 25 + 6 + 28 = 90
Total number of plants = 4
Substitute the known values in the above equation So, we have the following equation
Mean plant = 90/4
Mean plant = 22.5
For the three plants, we have
Total number of tomatoes = 31 + 25 + 28 = 84
Total number of plants = 3
Substitute the known values in the above equation So, we have the following equation
Mean plant = 84/3
Mean plant = 28
See that the difference is an increment of
Increment = 28 - 22.5

Step-by-step explanation:
Area of prism:Area of one regular hexagon is given. Multiply 23 *2 and it will give the area of two regular hexagons.
There are 6 rectangles. Find the area of one rectangle and multiply it by 6.
Area of regular hexagon = 23 cm²
Area of rectangle = length * width
= 8 * 3
= 24 cm²
Area of the regular hexagon prism = 2* area of regular hexagon + 6*area of rectangle.

Answers
Considering a discrete distribution modeling the situation, it is found that:
a) The expected value of each $1 bet in roulette is of: -$0.988.
b) The interpretation is given as follows: Over time, you should expect to lose about 999 cents for every dollar you bet.
What is the expected value of a discrete distribution?The expected value of a discrete distribution is calculated as the sum of each outcome multiplied by it's respective probability.
The total number of outcomes for the three-number bet is of:
10 x 10 x 10 = 1000.
As three numbers are taken, and for each number, there are 10 possible outcomes.
Hence the probability of winning is of:
p = 1/1000.
As there is only one correct sequence.
The probability of losing is of:
p = 1 - 1/1000 = 999/1000.
Considering a payout of $11 for a $1 bet, the distribution of earnings is presented as follows:
P(X = 11) = 1/1000.P(X = -1) = 999/1000.Hence the expected value of a $1 bet is calculated as follows:
E(X) = 11/1000 - 999/1000 = -$0.988.
Which means that you are expected to lose approximately 99 cents for every dollar that you bet.

Answers
86.135 is the IQ score separating the bottom 25% from the top 75%.
The number between a data set's lowest and median is known as the first quartile. We would utilize a Z table to locate it.
As we are looking on the left side of distribution, value of z-score will be negative.
z-score equation for x : [tex]z = \frac{x-M}{S}[/tex]
[tex]x = zS+M[/tex]
where x = value we're looking for
M = Mean
= 99.2
S = Standard deviation
= 19.5
z = z-score
= -0.67
Putting the value in equation,
x = -0.67*19.5 + 99.2
= -13.065 + 99.2
= 86.135
Hence, 86.135 is the IQ score separating the bottom 25% from the top 75%.

Answer:
t=1.33333 seconds
Step-by-step explanation:
1. We are give the the position function, s(t). We must differentiate s(t) twice in order to find the acceleration function, a(t).
s(t) = t⁶-2t⁵
Taking the power rule to differentiate s(t), we find the velocity function, v(t).
v(t) = d/dt (t⁶-2t⁵)
v(t) = 6t⁵-10t⁴
Differentiate v(t) using the power rule again to find the acceleration function, a(t).
a(t) = d/dt (6t⁵-10t⁴)
a(t) = 30t⁴-40t³
2. To find the other t value where acceleration is equal to zero, we must set a(t) to zero.
a(t) = 30t⁴-40t³ = 0
3. Algebraically solve for t. Factoring out 10t³ from a(t), we have:
10t³(3t-4)=0
Our solutions are t=0 and t=4/3.
The other value of t when acceleration is equal to zero is 4/3, or 1.33333 seconds.

GivenConveyor belt1: m(x) = 157.1xFind the equation of p(x) using table.
We see it is a proportional relationship, therefore:
p(x) = kx125.6 = 2kk = 125.6/2k = 62.8Conveyor belt2: p(x) = 62.8x
As we see 157.1 > 62.8 which means conveyor 1 belt is faster.
Answer:
The conveyor belt 1 is faster.
Step-by-step explanation:
Speed of conveyor belt 1,
→ m(x) = 157.1x
Now the speed of conveyor belt 2,
→ p(x) = x
→ p(125.6) = 2x || p(188.4) = 3x
→ x = 125.6/2 || x = 188.4/3
→ [ p(x) = 62.8 ] || [ p(x) = 62.8 ]
Then the fastest conveyor is,
→ m(x) = 157.1x > p(x) = 62.8
→ 157.1x > 62.8
→ Conveyor 1 > Conveyor 2
Hence, the conveyor belt 1 is faster.

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.
Slope of a Line :
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.
where "m" represents a line's slope.

B. The graph of K has a greater y-intercept
D. The graph of J has a greater slope.
Step-by-step explanation:
Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.
Y-interceptThe y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.
We see from the equation for function K that the constant is 8. This is the value of y when x=0.
Function K has the greater y-intercept (8 vs. 2).
SlopeThe slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.
The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.
Function J has the greater slope (5 vs. 3).

The probabilities in this problem are given as follows:
First strike is a critical hit: 33%.First strike is not a critical hit: 67%.First strike is critical and the second is not: 22%.Cause damage: 11%Not critical followed by two criticals: 7%.What are the probabilities?The probabilities for each strike are given as follows:
Critical hit: 33%.Not a critical hit: 67%, as 100 - 33 = 67.The probabilities are independent, meaning that for each trial they are the same.
Thus the probability that your first strike was a critical hit but not your second strike is obtained as follows:
P = 0.33 x 0.67 = 0.2211 = 22%. (rounded).
Damage is caused with two consecutive critical hits, hence:
p = 0.33 x 0.33 = 0.11 = 11%.

Evaluate this expression: (7 ⋅ 2) + 4^2 - 12 ÷ 4
I don't know how to figure this out
Answers
Explanation:
• = multiplication
^ = exponent
- = subtraction
÷ = division
You can use a strategy called GEMS to solve these expressions too.
G grouping symbols | () {} []
E exponents | n^2
M multiply/divide | ÷ x •
S subtract/add | + -
Always start with your grouping symbols. The grouping symbols are (7 • 2), which equals 14.
Now, our expression is 14 + 4^2 - 12 ÷ 4.
Next, you want to do your exponents.
4^2 = 16.
Now, our expression is 14 + 16 - 12 ÷ 4.
Next, you do division.
12 ÷ 4 = 3.
The expression is now 14 + 16 - 3.
You do the addition first.
14 + 16 = 30.
The expression is now 30 - 3.
Lastly, we do subtraction.
30 - 3 = 27.
I hope this helps!
