Answer: Papst blue ribbon

Step-by-step explanation:

Ryan lives in a trailer park. He likes to drink papst blue ribbon and not wear satin robes.

Answer:

112

Step-by-step explanation:

Find the lowest common multiple of 14 and 16.

To find the lowest common multiple:

1) Break the numbers down into their prime factors.

14 = [tex]2^{1}[/tex] x [tex]7^{1}[/tex]

16 = 2 x 8 = 2 x 2 x 4 = 2 x 2 x 2 x 2 =  [tex]2^{4}[/tex]

2) Multiply the highest power of each prime number.

We have three numbers, but only two are unique:  [tex]2^{1}[/tex] , [tex]7^{1}[/tex] and  [tex]2^{4}[/tex]

  [tex]2^{4}[/tex] >  [tex]2^{1}[/tex] , so we will use  [tex]2^{4}[/tex]

[tex]7^{1}[/tex] x  [tex]2^{4}[/tex] = 7 x 16 = 112

The true statement about the graph of the parabola inequality given as y < x^2 + 2x - 6 is (b) the vertex is located at (-1,-7)

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The parabola inequality is given as

y < x^2 + 2x - 6

Next, we plot the graph of the parabola inequality

To plot this graph, we simply enter the inequality y < x^2 + 2x - 6 in a graphing calculator

From the attached graph, we can see that the vertex of the parabola inequality is at (-1, -7)

Hence, the true statement about the graph of the parabola inequality given as y < x^2 + 2x - 6 is (b) the vertex is located at (-1,-7)

The response times for a certain ambulance company are normally distributed with a mean of 12.5 minutes. Ninety-five percent of the response times are between 10 and 15 minutes. What is the standard deviation of the response time?

Answer: 12346

Step-by-step explanation:

Firstly, to round the decimal number 12345.6789 to its nearest whole number we will look at the tenth place. the digit to the immediate right of the decimal point.

Here in the given example 12345.6789, the tenth digit is 6.

If the tenth place digit is equal to or more than 5 we will round up and if it is less than 5 we will round down.

If the hundredth digit of the decimal number is equal to or more than 5, then round up.

Since the tenth digit 6 is >= 5 we will round up i.e. ( ones place digit + 1 ) and the remaining all digits next to the decimal point are removed.

Therefore, the number 12345.6789 rounded to the nearest whole number is 12346. if this is wrong im sorry but i think this is how i even double checked.

The domain and the range are  −∞ < x < ∞ and −∞ < y < ∞ while the intercept is (2, 0)

The domain of the function is the set of input values of the graph

The range of the function is the set of input values of the graph

The function is given as

g(x) = 3x + 6

The above function is a linear function

This means that the domain and the range of the function are the set of all real values

i.e. −∞ < x < ∞ and −∞ < y < ∞

Calculate x when g(x) = 0 to determine the x-intercept

So, we have

3x + 6 = 0

Divide through by 3

x + 2 = 0

This gives

x = -2

Hence, the domain and the range are  −∞ < x < ∞ and −∞ < y < ∞ while the intercept is (2, 0)

Check for Extraneous solution by putting value of x in the original equation -

Let x = 1

Which graph correctly shows the system of equations [tex]\left \{ {{x-2y=4} \atop {y=2x+4}} \right.[/tex] ?

Correct graph for the system of equations is 3rd graph.

We graph the collection of ordered pairs that make up the equation's solution when graphing a system of equations in two variables.

The universal equation for any straight line is y=mx+c. m is the line's slope, and c is the y-intercept.

First, we take the equations as x-2y=4 as equation (1) and y=2x+4 as equation (2).

Now solve the equation (1)

x-2y=4

The equation is not in the form of y=mx+c.

So, we write as y= [tex]\frac{1}{2}[/tex]x-2

Here, slope m=[tex]\frac{1}{2}[/tex] and y-intercept is (0,-2).

If we take x=2 we get y=-1.

y= [tex]\frac{1}{2}[/tex](2)-2

y=1-2

y=-1

Now we have 2 solution for the equation (1) that are (0,-2) and (2,-1).

If we see the third graph in the given options.

There is a blue straight line and that is the line for equation (1) there we can see the points (0,-2) and (2,-1).

Now solve the equation (2)

y=2x+4

The equation is in the form of y=mx+c.

Here, slope m=2 and y-intercept is (0,4).

If we take x=1 we get y=6.

y= 2(1)+4

y=2+4

y=6

Now we have 2 solution for the equation (2) that are (0,4) and (1,6).

If we see the third graph in the given options.

There is a green straight line and that is the line for equation (2) there we can see the points (0,4) and (1,6).

Therefore, the correct graph for the given system of the equation[tex]\left \{ {{x-2y=4} \atop {y=2x+4}} \right.[/tex] is the third graph.

The value of m<1 is 65 degrees

From the diagram shown, we have that;

It is important to note that angles on a straight line sum up to 180 degrees

Also, corresponding angles are equal

Then, we have that;

m<2 + m<3 = 180°

Substitute the values

9x + 7 + 5x + 5 = 180

collect like terms

14x = 180 - 12

14x = 168

Make 'x' the subject

x = 168/ 14

x = 12

We have that;

m<3 = 5x + 5 = 5(12) + 5 = 60 + 5 = 65

Two parallel lines have equal slope.

Therefore, slope of line y = -2/9x + 6 is equal to the slope of the line joining the points (3,2).

Slope of line is given by :

m= -[(coefficient of x) / (coefficient of y)]

Where m= slope,

Slope of line y = -2/9x + 6

2/9x + y = 6

(m1) slope of equation g = -x/y

                                     = -(2/9)/1

                                     = -2/9

Since equation h is parallel to g

So, m1=m2

That is slope of equation h=slope of equation g

We know,

Equation of the line h having slope=m2= -2/9

passing through the slope of the point (3,2) is,

       y-y1=m(x-x1)

Replace with values x1,y1=(3,2) and m=-2/9

      y-2=(-2/9)(x-3)

We can solve it :      

       9y-18=-2x+6

       2x+9y=6+18

       2x+9y=24

       2x+9y-24=0

Hence,

     2x+9y-24=0 is the equation of h.

Therefore,

Line g has an equation of y = -2/9x + 6. Parallel to line g is line h, which passes through the point (3, 2), then the numbers in the equation of line h is 2x+9y-24=0

2x - 3y=  - 15

Subtract equation(i) from equation(ii)

Therefore,

The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity. That means, we can say that if one values will increase then other will automatically decrease and vice versa.

Let say if x and y are two values and k is a constant value, then

According to inverse variation

k = xy or y = k/x

Step-by-step explanation:

Based on the concept of conditional probability, the probability that the first iPod is defective and the others are not defective is approximately 0.1842

Conditional Probability is a term that is used to describe the chances that some outcome occurs given that another event has also occurred.

Generally, the functional probability is often stated as the probability of B given A and is written as P(B|A), where the probability of B depends on that of A happening

In this case, to find the answer we break down the problem step by step:

Step 1: Find the probability that the first iPod is defective.

Since there are 3 defective iPods out of 20 total the probability of selecting a defective iPod on the first draw is 3/20.

Step 2: Find the probability that the second and third iPods are not defective.

After selecting a defective iPod there are 19 remaining iPods in the box out of which 17 are not defective.

Hence, the probability of selecting a non-defective iPod on the second draw is 17/19.

Also, given that the probability of selecting a non-defective iPod on the third draw (assuming the previous two iPods were not defective) is 16/18.

Step 3: Finding the overall probability.

The overall probability of the first iPod being defective and the second and third iPods being non-defective can be computed by multiplying the probabilities of each step:

Probability = (3/20) * (17/19) * (16/18)

= (51/380) * (16/18)

= 0.1842105

Therefore, in this case, it is concluded that the correct answer is approximately 0.1842 or 18.42%.
