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

The absolute value of a given number is [tex]4\frac{1}{2}[/tex].

The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To find the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.

The given number is [tex]-4\frac{1}{2}[/tex].

So, absolute value of a number is

|[tex]-4\frac{1}{2}[/tex]|= [tex]4\frac{1}{2}[/tex]

Hence, the absolute value of a given number is [tex]4\frac{1}{2}[/tex].

Step-by-step explanation:

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.

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.

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]

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.

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.

Step-by-step explanation:

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

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

Answer:

#5 = $676.40

#6 = $522.50

Step-by-step explanation:

Lets start with number 5.

Marla earns $17.80 per hour. If she works 38 hours a week she will earn $(17.80*38) per week which is $676.40 per week

Now for number 6

He earns $11.00 an hour for a 40 hour work week. If he gets paid 1.5 that (1.5 his normal rate) for overtime and he has 45 hours vs his 40 hours, heres how we solve:

Solve for his pay on a normal week:

11 * 40 = 440 a week on a normal week

Find out how much overtime

45-40 = 5 hours

Calculate the pay for the overtime

(11*1.5) x 5 =

16.50 x 5 = 82.5

Add the two pays together

440 + 82.50 = $522.50

[tex]\frac{8}{6}=1\frac{1}{3}[/tex]

Step-by-step explanation:

[tex]3\frac{1}{2}-2\frac{1}{6}[/tex]  Fractions cannot be added or subtracted unless they have the same denominator (bottom number)

[tex]\frac{7}{2}-\frac{13}{6}[/tex]     Change to an improper fraction. Multiply the denominator times the whole number (number on the side) then add to the numerator (top number) and place over the the denominator (3*2+1=7→[tex]\frac{7}{2}[/tex])

[tex](\frac{7}{2}*\frac{3}{3})[/tex] - [tex]\frac{13}{6}[/tex]   In order to give both fractions the same denominator, find the least common denominator (LCD = one number that both denominators will divide evenly into) LCD = 6. Then multiply the top and bottom by a number that gives the LCD. We only need to multiply the first fraction  top and bottom by 3.

[tex]\frac{21}{6} - \frac{13}{6} = \frac{8}{6}[/tex]   This is an improper fraction because the numerator is larger than the denominator. To make a mixed number divide the numerator by the denominator and simplify.

[tex]\frac{8}{6} = 1\frac{2}{6} = 1\frac{1}{3}[/tex]   [tex](\frac{2}{6} \frac{divided by}{divided by}\frac{2}{2} = \frac{1}{3})[/tex]
