The defensive coaches had hoped that the average number of tackles of the opponent’s QB would increase during the game in a distribution of 15% of the tackles in the first quarter,15% in the second,30% in the third, and 40% in the fourth. The mean number of tackles for the 2007 season was as follows: 37, 35, 73, 40. Did the mean sacks per game fit the desired distribution? Let a = 0.10.
5. Mr. Q's class is having a give-
away where his students can
receive 100 classroom credits.
He will pull names out of a hat
and select two winners. Once a
student wins, they are not
eligible to win a second time. If
there are 40 total people in the
class, including you and your
best friend.
What is the probability that both you and your best friend get the 100 classroom
credits? (Show work please)
Answer:
The probability that both me and my best friend get the 100 classroom credits is 0.06%.
Step-by-step explanation:
Since Mr. Q's class is having a give-away where his students can receive 100 classroom credits, and he will pull names out of a hat and select two winners, and once a student wins, they are not eligible to win a second time, if there are 40 total people in the class, including me and my best friend, to determine what is the probability that both me and my best friend get the 100 classroom credits, the following calculation must be performed:
I = 1/40 = 0.025
my best friend = 1/39 = 0.02564
0.02564 x 0.025 = X
0.0006410 = X
X x 100 = 0.064
Therefore, the probability that both me and my best friend get the 100 classroom credits is 0.06%.
Celia simplified the expression Negative 4 x (1 minus 3) minus (2 x + 2). She checked her work by letting x = 5 in both expressions. Her work for the original expression is shown below.
Negative 4 x (1 minus 3) minus (2 x + 2) = negative 4 (5) (1 minus 3) minus (2 (5) + 2) = negative 20 (negative 2) minus 12 = 40 minus 12 = 28.
Celia knows that the simplified expression should also equal 28 when x = 5. Which shows Celia’s simpllifed expression?
Answer:
-4x (1-3) - (2x + 2)
-4(5)(1-3) - (2(5) + 2)

Suppose you plan to go out for a picnic during spring break. You plan to bring sandwiches, fruits, and drinks. But you only have one picnic basket that can only hold a certain capacity. Each of the items has a value and a size, and you cannot hold all your items in the basket. The picnic basket can hold a total size of 17. Given that the size and the value of items are as follows, how many of each item should you bring to maximize the total value?
Size Value
Sandwich 9 6
Fruit 3 4
Drink 4 6
a) List and explain carefully what the decision variables are.
b) Write out the objective function.
c) Write out the constraints.
d) Write the linear program.
e) Solve the Linear Programming problem using excel. Show your results.
Answer:
e) z (max) = 24
x₁ = x₂ = 0 x₃ = 4
Step-by-step explanation:
a) The problem requires maximizing the total value from sandwich fruits and drink, therefore the objective function is associated to the sum of the values of each value.
We have three variables xi ( x₁, x₂, x₃ ) the values of sandwich, fruits and drink, and we have to maximize such quantities subject to the constraint of size (the capacity of the basket)
b) z = 6*x₁ + 4*x₂ + 6*x₃ Objective Function
Constraint :
basket capacity 17
9*x₁ + 3*x₂ + 4*x₃ ≤ 17
General constraints:
x₁ ≥ 0 x₂ ≥ 0 x₃ ≥ 0 all integers
e) z (max) = 24
x₁ = x₂ = 0 x₃ = 4
NOTE: Without the information about fractional or decimal feasible solution we decided to use integers solution

Assume that y varies inversely with x. If y = 7 when x = 2/3, find y when x = 7/3.
y = [?]
Answer:
y = 2
Step-by-step explanation:
varies inversely
xy = k
y = 7 when x = 2/3
(2/3)7 = k
14/3 = k
k = 14/3
--------------------
find y when x = 7/3
(7/3)y = 14/3
multiply both sides by 3/7
y = 14/3 * 3/7
y = 2
Answer: y = 2
Step-by-step explanation: When we have two sets of inversely related coordinates, x₁ and y₁, and x₂ and y₂, we can use the product rule, shown below, to find the missing value.
x₁y₁ = x₂y₂Since we know that y = 7 when x = 2/3, one set of coordinates will be 7 and 2/3 and since we want to find the value of y when x = 7/3, our other coordinates will be 7/3 and y.
(2/3)(7) = (7/3)(y)
So we have 14/3 = 7/3y and solving for y from here, we find that y = 2.

Find the standard form of the equation of the circle with endpoints of a diameter at the points (7,8) and (-3,6). Type the standard form of the equation of this circle
Answer:
The equation of the circle is [tex](x - 2)^2 + (y - 7)^2 = 21[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle, with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Diameter at the points (7,8) and (-3,6).
The diameter is the distance between these two points, so:
[tex]D = \sqrt{(-3-7)^2+(6-8)^2} = \sqrt{104}[/tex]
Radius is half the diameter, so:
[tex]r = \frac{\sqrt{104}}{2} = \frac{\sqrt{104}}{\sqrt{4}} = \sqrt{\frac{104}{4}} = \sqrt{21}[/tex]
So
[tex]r^2 = (\sqrt{21})^2 = 21[/tex]
Center:
Midpoint of the diameter, which is the mean of the coordinates. So
[tex]x_0 = \frac{7 - 3}{2} = \frac{4}{2} = 2[/tex]
[tex]y_0 = \frac{8 + 6}{2} = \frac{14}{2} = 7[/tex]
Then
[tex](x - 2)^2 + (y - 7)^2 = 21[/tex]

The perimeter and total area of the composite shape are; 292.53 and 65.135 .
What is the area of a square?The area of a square can be calculated as the square of the sides of a given figure.
The area of a square = side x side
The Square part of perimeter = 40.
Half circle = 25.135.
The perimeter = 40 + 25.135 = 65.135 is perimeter.
The Area of square = 192
Are of half circle: 100.53.
Together 292.53
Rounded =292.48
Therefore, the perimeter and total area of the composite shape are; 292.53 and 65.135 .

One side of a triangle is three times the shortest side.
"The third side is 7 feet more than the shortest side. The
perimeter is 62 feet. Find all three sides.
Answer:
The lengths of the sides are - 11, 18, 33
Step-by-step explanation:
Shortest side = x
Second side = 3x
Third side = 7 + x
Perimeter = sum of all three sides
62 = x + 3x + x + 7
62 = 5x + 7
55 = 5x
x = 11
Shortest side = x = 11
Second side = 3x = 33
Third side = 7 + x = 18
