Let's begin by identifying key information given to us:
\(y=-x+7\)In order to graph this equation, we will assume values for the x-variable to obtain the output. This is shown below:
\(\begin{gathered} y=-x+7 \\ x=-5 \\ y=-(-5)+7=5+7=12 \\ \Rightarrow(-5,12) \\ \\ x=-1 \\ y=-(-1)+7=1+7=8 \\ \Rightarrow(-1,8) \\ \\ x=2 \\ y=-2+7=5 \\ (2,5) \\ \\ x=4 \\ y=-4+7=3 \\ \Rightarrow(4,3) \\ \\ x=7 \\ y=-7+7=0 \\ \Rightarrow(7,0) \end{gathered}\)We will proceed to plot this on a graph as shown below:

Diane, Sam, and Boris served a total of 54 orders Monday at the school cafeteria. Diane served 6 fewer orders than Sam. Boris served 2 times as
many orders as Sam. How many orders did they each serve?
Number of orders Diane served:
Number of orders Sam served:
Number of orders Boris served:
Answers
Answer:
Let's denote:
- The number of orders Diane served as `D`
- The number of orders Sam served as `S`
- The number of orders Boris served as `B`
From the problem, we know:
1. `D + S + B = 54` (the total number of orders they served)
2. `D = S - 6` (Diane served 6 fewer orders than Sam)
3. `B = 2S` (Boris served 2 times as many orders as Sam)
We can substitute equations 2 and 3 into equation 1 to solve for the variables:
Substitute `D` and `B` in equation 1:
`(S - 6) + S + 2S = 54`
Combine like terms:
`4S - 6 = 54`
Add 6 to both sides:
`4S = 60`
Divide by 4:
`S = 15`
Now that we know `S = 15`, we can find `D` and `B` by substituting `S` into equations 2 and 3:
`D = S - 6 = 15 - 6 = 9`
`B = 2S = 2 * 15 = 30`
So, Diane served 9 orders, Sam served 15 orders, and Boris served 30 orders.

A computer software company has submitted bids on two separate government contracts, A and B. The company estimates that it has a 36 percent chance of winning contract A and a 53 percent chance of winning contract B. The company believes that winning contract A is independent of winning contract B. Answer the following questions, rounding your answers to two decimal places where appropriate.
a) What is the probability that the company will win both contracts?
b)What is the probability that the company will win at least one of the two contracts?
Now suppose that the company believes that, given that it wins contract B, it has a 40 percent chance of winning contract A.
c)What is the probability that the company will win both contracts?
d) What is the probability that the company will win at least one of the two contracts?
e) If the company wins contract B, what is the probability that it will not win contract A?
Answers
Using probability concepts, it is found that there is a:
a) 0.1908 = 19.08% probability that the company will win both contracts.
b) 0.6992 = 69.92% probability that the company will win at least one of the two contracts.
c) 0.212 = 21.2% probability that the company will win both contracts.
d) 0.6992 = 69.92% probability that the company will win at least one of the two contracts.
e) 60% probability that it will not win contract A.
Conditional probability:
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
In which
P(B|A) is the probability of event B happening, given that A happened. \(P(A \cap B)\) is the probability of both A and B happening. P(A) is the probability of A happening.Item a:
0.36 probability of winning contract A.0.53 probability of winning contract B.The probability of both is the multiplication of each probability, thus:
\(p = 0.36(0.53) = 0.1908\)
0.1908 = 19.08% probability that the company will win both contracts.
Item b:
1 - 0.36 = 0.64 probability of not winning contract A.1 - 0.53 = 0.47 probability of not winning contract B.The probability of winning none is:
\(p_N = 0.64(0.47) = 0.3008\)
The probability of winning at least one is:
\(p = 1 - p_N = 1 - 0.3008 = 0.6992\)
0.6992 = 69.92% probability that the company will win at least one of the two contracts.
Item c:
Now, conditional probability is used, considering \(P(B) = 0.53, P(A|B) = 0.4\). Hence:
\(P(A \cap B) = P(B)P(A|B) = 0.53(0.4) = 0.212\)
0.212 = 21.2% probability that the company will win both contracts.
Item d:
If it doesn't wins contract A, the probability of not winning B is the same as in item B, so the probability of winning none is the same, which means that the probability of winning at least one is the same, that is:
0.6992 = 69.92% probability that the company will win at least one of the two contracts.
Item e:
If it wins contract B, it has a 40% percent change of winning contract A, thus 100% - 40% = 60% probability that it will not win contract A.A similar problem is given at https://brainly.com/question/25229135

There are some different ways to find the area of a donut shape. One is to multiply its centerline length by its width. We'll use that here to find the shaded area of the sector.
The centerline radius of shaded area A is ...
(6x -2) cm + (1/2)(4x cm) = 8x -2 cm
The length of the centerline is ...
s = rθ = (8x -2)(π/4) . . . . . . for a central angle of 45° = π/4 radians
Then the area A is ...
area A = (π/4)(8x -2)(4x) = 2πx(4x -1) . . . cm^2
__
The radius of circle B is ((4 -4x) cm)/2 = (2 -2x) cm. The area of circle B is ...
A = πr^2 = π(2 -2x)^2 cm^2
We're told the two areas are equal, so we have ...
2πx(4x -1) = π(2 -2x)^2 . . . . . . . expressions for the areas are equal
8x^2 -2x = 4x^2 -8x +4 . . . . . . divide by π, eliminate parentheses

Find the missing angle according to the Triangle Exterior Angle Theorem
Answers
Answer:
x = 105 degrees
Step-by-step explanation:
First, figure out the interior angle, we can do this ading the two angles and then subtracting the sum from 180 (since the interior angle of a triangle adds up to 180 degrees)
180 - (55 + 50) = 75
next, we can figure out x by taking the sum (75) and subtracting that from 180 since it is a supplementary angle:
180 - 75 = 105
x = 105
Answer:
105 degrees!
Step-by-step explanation:
all the angles in a triangle must add to 180.
50+55= 105
therefore, the missing angle would be 75
x+75 must also add to 180 so the answer would be: 105 because 75+105= 180

Answers
60 units / 14 units per case ≈ 4.29 cases
Since you can't have a fractional number of cases, you would need to round up to the nearest whole number of cases. Therefore, you would need 5 full cases.
To determine the number of additional items needed to fulfill the order, you can subtract the number of units in the full cases from the total number of units:
60 units - (5 cases * 14 units per case) = 10 additional items
So, in total, you would need 5 full cases and 10 additional items to fulfill the order of 60 units.

Using the slope formula, find the slope of the line through the given points. (4. - 2) and ( - 2, - 2)
Answers
- 0/6
Step-by-step explanation:
*I’m pretty sure you meant to type “(4, -2)” instead of “(4. -2)” Anyways…*
m = slope
m = change in y/change in x
m = y2 - y1/x2 - x1
Points: (4, -2) and (-2, -2)
m = -2 - -2/-2 - 4
m = 0/-6
The slope is - 0/6
Hi! I'm happy to help!
To solve this problem, we have to find the slope, which is rise over run, or how much the line rises and how far forward the line goes.
We find the slope using this formula (slope formula)
m(slope)=\(\frac{y_{2}-y_{1} }{x_{2} -x_{1} }\)
This refers to the second y point minus the first y point, divided by the second x point minus the first x point. Y refers to the y axis, so that is the rise, because it is the difference of height in the line. X refers to the x axis, so that is the run, because it is the difference in how far it travels forward.
Our second y point is -2, our first y point is also -2. Our second x point is -2, and our first y point is 4. Let's plug in our values.
\(\frac{-2-(-2)}{-2-4}\)
Let's simplify this so there isn't a double negative.
\(\frac{-2+2}{-2-4}\)
Now, let's solve
\(\frac{0}{-6}\)
0 divided by -6, is still 0, so there is no slope or the slope is 0. This means that the line is horizontal and the y coordinate doesn't change.

The equation for the line of best fit is: C. y = 0.894x + 0.535.
How to determine the equation for the line of best fit?In order to determine the equation for the line of best fit, we would create a table of values based on the given x-values and y-values as follows;
x y x² y² xy__
5 4 25 16 20
6 6 36 36 36
9 9 81 81 81
10 11 100 121 110
14 12 196 144 168
Sum 438 398 415
Next, we would calculate the mean of the x and y variables as follows;
Mean = [∑(x)]/n
Mean = 44/5
Mean, \(\bar{x}\) = 8.8
Mean = [∑(y)]/n
Mean = 42/5
Mean, \(\bar{y}\) = 8.4
∑(x - \(\bar{x}\))(x - \(\bar{y}\)) = (5-8.8)(4-8.4) + (6-8.8)(6-8.4)+(9-8.8)(9-8.4)+(10-8.8)(11-8.4)+(14-8.8)(12-8.4)
∑(x - \(\bar{x}\))(x - \(\bar{y}\)) =45.4
∑(x - \(\bar{x}\))² = (5-8.8)²+(6-8.8)²+(9-8.8)²+(10-8.8)²+(14-8.8)²
∑(x - \(\bar{x}\))² = 50.8
Now, we can determine the slope coefficient for the line of best fit:
Slope (b) = 45.4/50.8
Slope (b) = 0.894.
Lastly, we would determine the intercept (a) as follows;
\(a = \bar{y} - b\bar{x}\)
a = 8.4 - (0.894)8.8
a = 0.535
Therefore, the required equation is y = 0.894x + 0.535.

Step-by-step explanation:
In the given figure, secants PA and PC are intersecting outside of the circle at point P.
PA = PB + AB = 7 + 5 = 12
PC = 14, PD =?
By the property of intersecting secants outside of a circle:
\( PB \times PA = PD\times PC\\
\therefore 7\times 12 = PD \times 14\\
\therefore 84 =PD \times 14\\\\
\therefore PD = \frac{84}{14}\\\\
\therefore PD = 6\\\\
\)
Answer: PD = 6
Step-by-step explanation:
PD = PB + AB = 12
When two secant lines intersect each other outside a circle, the products of their segments are equal. This is:
PB x PA = PD x PC
7 x 12 = PD x 14
PD = 7 x 12 / 14
PD = 6
Cold Beans wants to make a blend of their two best coffees, Guatemalan and Jamaican coffee. The pound of Guatemalan Coffee costs $11/lb and the other one costs $5/lb. If they want the cost of a 6 pound bag of blend to be $8/lb, how much Guatemalan coffee should they use per pound of the blend?
Answers
For each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.
This means that in a 6-pound bag of the blend, they would use \(3 \times 6 = 18\)pounds of Guatemalan coffee.
Let's assume that x pounds of Guatemalan coffee are used per pound of the blend.
Given information:
Cost of Guatemalan coffee = $11/lb
Cost of the other coffee = $5/lb
Desired cost of the blend = $8/lb
Total weight of the blend = 6 pounds
To find the ratio of Guatemalan coffee to the total blend, we can set up the equation:
\((x \times 11 + (6 - x) \times 5) / 6 = 8\)
In this equation, \((x \times 11)\) represents the cost of the Guatemalan coffee in the blend, and\(((6 - x) \times 5)\) represents the cost of the other coffee in the blend.
The numerator is the total cost of the blend, and we divide it by 6 (the total weight of the blend) to find the cost per pound.
Now, let's solve the equation for x:
(11x + 30 - 5x) / 6 = 8
6x + 30 = 48
6x = 48 - 30
6x = 18
x = 18/6
x = 3
Therefore, for each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.
This means that in a 6-pound bag of the blend, they would use \(3 \times 6 = 18\)pounds of Guatemalan coffee.
To summarize, to achieve a cost of $8 per pound for a 6-pound bag of blend, Cold Beans should use 3 pounds of Guatemalan coffee per pound of the blend.
