Answer:
The dimensions of the largest shed are 17 ft by 17 ft.
The area of the largest shed is 289 sq ft.
Step-by-step explanation:
Given that:
Fixed perimeter of the rectangular shed = 68 ft
To find:
The dimensions of the largest shed that can be built = ?
And
Area of the largest shed that can be built = ?
Solution:
First of all, let us have a look at the formula for perimeter of a rectangular shape shed:
Perimeter of a rectangle = 2 [tex]\times[/tex] (Length + Width)
68 = 2 [tex]\times[/tex] (Length + Width)
Length + Width = 34
The largest possible values are only in the case when the rectangle is a square.
i.e. Length = Width
Therefore values of length and width are:
Length = Width = [tex]\frac{34}{2} = 17\ ft[/tex]
Area of a square is given by the formula:
[tex]A = Side \times Side[/tex]
[tex]A[/tex] = 17 [tex]\times[/tex] 17 = 289 sq ft
The answer is:
The dimensions of the largest shed are 17 ft by 17 ft.
The area of the largest shed is 289 sq ft.
The Cardiovascular Risk in Young Finns Study showed average baseline triglyceride levels among 920 people of 0.926 mmol/L associated with a total sum of squared deviations of approximately 160 mmol/L. If a linear regression analysis of baseline triglyceride levels on physical activity levels had an R-squared of 0.30, what are the sum of squared deviations explained by the regression model?
a. 112 mmol/L
b. Not enough information
c. 48 mmol/L
Answer:
The sum of the squared deviations explained by the regression model is:
c. 48 mmol/L
Step-by-step explanation:
Average baseline triglyceride levels among 920 people = 0.926 mmol/L
Total sum of squared deviations, approximately = 160 mmol/L
Linear regression analysis of baseline triglyceride levels on physical activity levels had an R-squared = 0.30
Therefore, the sum of the squared deviations explained by the regression model = 160 * 0.30 = 48 mmol/L

A deck of 52 cards is shuffled. The first five cards of the deck are red. What is the probability that the last card in the deck is the ace of spades
Answer:
The answer is "[tex]\frac{1}{47}[/tex]".
Step-by-step explanation:
Although the five first players are red, the very first five cards are not spaded as the spad is a black card.
Its chance of the final card mostly on deck being the ace of spades is therefore determined as:
[tex]= \frac{1}{\text{Number of remaining cards with the initial 5 cards}} \\\\= \frac{1}{47}[/tex]
Thus, [tex]\frac{1}{47}[/tex] here is the necessary chance.
Answer:
1/47
Step-by-step explanation:
52 cards
5 red
probability= last card ace of spades
First do, 52-5, which gives you 47, and last card ace of spades, is 1, so 1/47 is the answer

A concession stand sell hot dogs and hamburgers. At a football game, 84 hot dogs and 36 hamburgers were sold for $276. At another football game, 60 hotdogs and 18 hamburgers were sold for $174. Wrote a system of equations to represent this situation. Then solve the system of equations.
Answer:
The concession stand sold 46 hot dogs and 32 hamburgers.
Step-by-step explanation:
The first thing to do in algebraic problems is assign variables to things we don't know, so let's start there:
We don't know how many hot dogs the concession stand sold, so we will call that number d.
We don't know how many hamburgers the concession stand sold, so we will call that number h.
Now we translate the statements into algebraic equations:
The number of hot dogs and hamburgers that were sold is 78, so d+h=78.
If each hot dog is sold for 1.25, then the total revenue from hot dogs is given by 1.25d. In the same way, the total revenue from hamburgers is 1.50h. The total revenue from both hot dogs and hamburgers should be the sum of these, and since we are told the total revenue is 105.50, we can say 1.25d+1.5h=105.5.
We now have a system of two linear equations:
d+h=78
1.25d+1.5h=105.5
We can solve it using several methods, though I'm going to go with substitution. Use the first equation to solve for d:
d+h=78
→d=78−h
Now plug this in for d in the second equation:
1.25d+1.5h=105.5
→1.25(78−h)+1.5h=105.5
Solving for h, we have:
97.5−1.25h+1.5h=105.5
0.25h=8
h=8.25→h=32
Since h+d=78,
32+d=78→d=46
The concession stand therefore sold 46 hot dogs and 32 hamburgers.
From the given situation the cost of each hot dogs is $2 and the cost of each hamburgers is $3.
For the given situation we need to find a system of equations.
What are the system of equations?In algebra, a system of equations comprises two or more equations and seeks common solutions to the equations. "A system of linear equations is a set of equations which are satisfied by the same set of variables."
Let the cost of hot dogs be x and the cost of hamburgers be y.
At a football game, 84 hot dogs and 36 hamburgers were sold for $276 =
84x+36y=276
⇒ 21x+9y=69 ..........(1)
At another football game, 60 hotdogs and 18 hamburgers were sold for $174 = 60x+18y=174
⇒ 10x+3y=29 ..........(2)
Multiply equation (2) by 3, that is 30x+9y=87 ..........(3)
Subtract equation (3) and (1)
That is, 30x+9y-(21x+9y)=87-69
9x=18
⇒ x=2
Put x=2 in equation (1), we get 21(2)+9y=69
⇒ 42+9y=69
⇒ 9y=27
⇒ y=3
Therefore, from the given situation the cost of each hot dogs is $2 and the cost of each hamburgers is $3.

A slow pitch softball diamond is actually a square 61 ft on a side. How far is it from home to second base?
Answer:
This would be the same as an isosceles right triangle. It would be 61ft x (square root of 2) = ~86.3ft
This is rounded of course...
The distance from from home to second base is 86.26 ft.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, a slow pitch softball diamond is actually a square 61 ft on a side.
A slow-pitch softball diamond is actually a square shape.
The side length of the square is 61 ft
Here ABCD is square. The length of the side is AB=BC=CD=DA=60 feet.
Consider the distance between home base to second base is the hypotenuse if we draw a right triangle using the diagonal across the square and two sides of the square.
Let us assume the diagonal distance from home to second base BD=x.
Let us find the distance from home base to second base by using Pythagorean Theorem:
Now, x²=61²+61²
x²=3721+3721
x²=7442
x=√7442
x=86.26 ft
Therefore, the distance from from home to second base is 86.26 ft.

Find the length and width (in feet) of a rectangle that has the given area and a minimum perimeter.Area: 49 square feet ft (smaller value) ft (larger value)
Answer:
Length = 7 ft
Breadth = 7 ft
Step-by-step explanation:
Let lenght of rectangle be x
and breadth be y
Area = [tex]49\ \text{ft}^2[/tex]
[tex]xy=49\\\Rightarrow x=\dfrac{49}{y}[/tex]
Permiter of a rectangle is given by
[tex]P=2(x+y)\\\Rightarrow P=2x+2y\\\Rightarrow P=2\times\dfrac{49}{y}+2y\\\Rightarrow P=\dfrac{98}{y}+2y[/tex]
Differentiating with respect to y we get
[tex]\dfrac{dP}{dy}=-\dfrac{98}{y^2}+2[/tex]
Equating with zero
[tex]0=-\dfrac{98}{y^2}+2\\\Rightarrow -2=-\dfrac{98}{y^2}\\\Rightarrow y^2=\dfrac{98}{2}\\\Rightarrow y^2=49\\\Rightarrow y=7[/tex]
Double derivative of the equation
[tex]\dfrac{d^2P}{dy^2}=2\dfrac{98}{y^3}\\\Rightarrow \dfrac{d^2P}{dy^2}=\dfrac{196}{y^3}>0[/tex]
So the value of y is minimum at 7.
[tex]x=\dfrac{49}{y}=\dfrac{49}{7}\\\Rightarrow x=7[/tex]
Hence, [tex]x=7,y=7[/tex]
The mimimum length and breadth of the rectangle is both 7 ft.

92% of what number is 351.
Thanks
Answer:
x = 381.52
Step-by-step explanation:
We start by writing 92% in decimal form: 92% = 0.92
Now we want to find 92% of what number "x" equals 351, and write the equation in math form that represents such statement:
0.92 * x = 351
solve for "x" by dividing both sides by 0.92:
x = 351/0.92
which gives approximately:
x = 381.52

A box of 11 transistors has 4 defective ones.
A) If 2 transistors are drawn from the box together, what is the probability that both transistors are defective?
B) If 2 transistors are drawn from the box together, what is the probability that neither transistor is defective?
C) If 2 transistors are drawn from the box together, what is the probability that one transistor is defective?
Answer:
(a) 0.1325
(b) 0.4045
(c) 0.463
Step-by-step explanation:
Let X denote the number of defective transistors.
The proportion of defective transistors is, p = 4/11 = 0.364.
All the transistors are independent of the others.
The random variable X follows a binomial distribution.
(a)
Compute the probability that both transistors are defective, if 2 transistors are drawn from the box together as follows:
[tex]P(X=2)={2\choose 2}(0.364)^{2}(1-0.364)^{2-2}\\\\=1\times 0.132496\times 1\\\\=0.132496\\\\\approx 0.1325[/tex]
(b)
Compute the probability that neither transistors are defective, if 2 transistors are drawn from the box together as follows:
[tex]P(X=0)={2\choose 0}(0.364)^{0}(1-0.364)^{2-0}\\\\=1\times 1\times 0.404496\\\\=0.404496\\\\\approx 0.4045[/tex]
(c)
Compute the probability that one transistors are defective, if 2 transistors are drawn from the box together as follows:
[tex]P(X=1)={2\choose 1}(0.364)^{1}(1-0.364)^{2-1}\\\\=2\times 0.364\times 0.636\\\\=0.463008\\\\\approx 0.463[/tex]
