Answer:
There are typically 12 decision variables and 7 constraints. ( option A )
Step-by-step explanation:
Given that there are 4 sources and 3 destinations The true statement is :
There are typically 12 decision variables and 7 constraints.
Because : In general linear programming optimization
number of decision variables in transportation = destination * source
= 3 * 4 = 12 variables
number of constraints = destination + sources = 3 + 4 = 7 constraints

Step-by-step explanation:
If a soil sample test gives a positive result, it is ___% likely that the soil sample contains organic matter.
Answer:
91.72% likely that the soil sample contains organic matter.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have that:
Of 700 samples that contain organic matter, 665 give a positive result and 700 - 665 = 35 give a negative result.
Of 300 samples that do not contain organic matter, 300 - 240 = 60 give a positive result and 240 give a negative result.
If a soil sample test gives a positive result, it is ___% likely that the soil sample contains organic matter.
665 with organic matter out of 665 + 60 = 725 positive tests.
665/725 = 0.9172
0.9172*100% = 91.72%.
91.72% likely that the soil sample contains organic matter.

what is the measure of m
9514 1404 393
Answer:
m = 8
n = 4√3
Step-by-step explanation:
The right triangles in this figure are all similar, so the ratios of hypotenuse to short side are the same.
(12+4)/m = m/4
64 = m² . . . . multiply by 4m
8 = m . . . . . . square root
__
Likewise, the ratio of long side to short side is the same.
12/n = n/4
48 = n² . . . . . . multiply by 4n
4√3 = n . . . . . take the square root
_____
Additional comment
You may have noticed that the ratios of side lengths are ...
4 : n : m = 4 : 4√3 : 8 = 1 : √3 : 2 . . . . . side lengths of a 30°-60°-90° triangle
This means the unmarked side is 8√3.
__
We supplied all of the missing lengths because we know this problem is likely to be presented in different forms, asking for values other than m.

The staff person is setting up the escape room and will add code books and flashlights. She needs at least 50 of a combination of code books and flashlights. (c + f ≥ 50) Each code book costs $2 and each flashlight costs $5. The budget for escape room supplies is no more than $175. Use c for the number of code books and f for the number of flashlights. What is the equation of the second inequality? *
Answer:
The second inequality is 2c + 5f ≤ 175
Step-by-step explanation:
Given - The staff person is setting up the escape room and will add code books and flashlights. She needs at least 50 of a combination of code books and flashlights. (c + f ≥ 50) Each code book costs $2 and each flashlight costs $5. The budget for escape room supplies is no more than $175.
To find - What is the equation of the second inequality?
Proof -
Let us assume that,
The number of code books = c
The number of flashlights = f
So,
Given that, She needs at least 50 of a combination of code books and flashlights
⇒ c + f ≥ 50
Now,
Given that, Each code book costs $2 and each flashlight costs $5.
So,
Cost of c code books = 2c
Cost of f flashlight = 5f
And Given, The budget for escape room supplies is no more than $175.
⇒2c + 5f ≤ 175
∴ we get
The second inequality is 2c + 5f ≤ 175

Answer: both equal 82
Step-by-step explanation: When you have parallel lines with a transversal, all the angles are either the same as the given angle or 180- the angle given. This is because they are all supplementary or equal. 1, 3, 5, and 7 are equal, 2, 4, 6, and 8 are equal. 180-98=82

A manufacturer produces widgets that are packaged in boxes of 100. The probability of a widget being defective is 0.021. Find the mean and standard deviation for the number of defective widgets in a box.
Answer:
[tex]\=x=2.1[/tex]
[tex]\sigma=2.03[/tex]
Step-by-step explanation:
From the question we are told that:
Sample size[tex]n=100[/tex]
Probability of a defective widget [tex]P=0.021[/tex]
Generally the equation for binomial trial is mathematically given by
[tex]q=1-p[/tex]

[tex]q=0.979[/tex]
Since X is binomial random variable with functions of n and p,The equation of mean \=x

What is the surface area?
And an explanation too but if not it’s ok
Answer:
356 cm.
Step-by-step explanation:
Whenever you find the surface area of a rectangular prism, remember this mnemonic:
LISA WILSON LOST HER WITCH HAT TWICE.
(TWICE) 2 (LENGTH × WIDTH + LENGTH × HEIGHT + WIDTH × HEIGHT)
In this rectangular prism, the length is 8, the width is 14, and the height is 3 (the order of numbers in length, width, and height does not matter).
Now, we can just plug in the numbers.
LENGTH × WIDTH + LENGTH × HEIGHT + WIDTH × HEIGHT
[tex]2(8*14+8*3+14*3) = 356.[/tex]
Therefore, the surface area of this rectangular prism is 356 centimeters.

solve for x lesser and greater x
Answer:
x = - 2, x = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given
(2x + 4)(3x - 2) = 0
Equate each factor to zero and solve for x
2x + 4 = 0 ( subtract 4 from both sides )
2x = - 4 ( divide both sides by 2 )
x = - 2 ← lesser x
3x - 2 = 0 ( add 2 to both sides )
3x = 2 ( divide both sides by 3 )
x = [tex]\frac{2}{3}[/tex] ← greater x
