The required probability is 0.55 while selecting a group that has an average value of at least $26.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

John has six bills of paper money in the following denominations $1, $5, $10, $20, $50, and $100.

The total number of possible combinations = [tex]^6c_3[/tex] = 6!/313! = 20

Combinations for which the average value is at least $26:

(1.5.100), (1,10,100), (1.20,100). (1.50,100), (5,10,100), (5,20,100), (5,50,100), (10,20,100), (10,20,50), (10,50,100), (20,50,100)

Number of favorable combinations = 11

So, required probability = 11/20 = 0.55

Thus, the required probability is 0.55 while selecting a group that has an average value of at least $26.

Answer:

The correct option is C) Store B is reducing prices by 5% more than Store A.

Step-by-step explanation:

Consider the provided information.

Store B is advertising a sale that will reduce prices on all merchandise by one over five.

Convert one over five in percentage as shown below:

[tex]\frac{1}{5}=\frac{1}{5}\times{\frac{20}{20}}[/tex]

[tex]\frac{1}{5}=\frac{20}{100}[/tex]

[tex]\frac{1}{5}=20\%[/tex]

Thus, the store B reduce the prices by 20%.

Store A reduces the prices on all merchandise by 15%.

From the above calculation, it is clear that store B reduces more prices by 5%.

Therefore, the correct option is C) Store B is reducing prices by 5% more than Store A.

The student should understand how to use the concept of ratios to solve the problem. With a 56-foot length of rope and a ratio of 3:1, each unit is worth 14 feet. Thus, the longer piece, representing 3 units, is 42 feet.

The question is essentially asking for one to utilize the concept of ratios in problem solving. Given that a 56-foot rope is cut into two pieces in the ratio 3:1, the lengths of the two pieces would be divided in line with the said ratio. To obtain the lengths of the pieces in feet, you have to add the two parts of the ratio (3+1=4) and then divide the total length by this sum. In this case, 56/4 equals 14 feet. Therefore, one unit of the ratio is equivalent to 14 feet.

Following on, you multiply the first part of the ratio which is 3 by 14 to get the longer piece's length. Thus, the length of the longer piece is 42 feet.

Answer:

$1486.41.

Step-by-step explanation:

Purchase price = $309,900

Down payment percent = 20 %

Remaining amount Percentage  = 100-20 = 80%

Mortgage amount = [tex]309900 \times 0.80[/tex]

                              =[tex]247920[/tex]

Formula of monthly payment : [tex]P =\frac{\frac{rM}{1 -(1 +\frac{r}{n})^-{nt}}}{n}[/tex]

where P = the payment,

r = the annual rate =6% = 0.06

M = the mortgage amount = $247920

t = the number of years=30

n = the number of payments per year= 12

Substitute the values.

[tex]P =\frac{\frac{0.06 \times 247920}{1 -(1 +\frac{0.06}{12})^-{12\times 30}}}{12}[/tex]

[tex]P=1486.40566196[/tex]

Hence the monthly payment is $1486.41.

True

Step-by-step explanation:

Two or more figures are congruent if all of their sides and angles are equal.

You can draw two not congruent triangles with equal congruent parts.

For example, you know that the sum of the inside angles of a triangle is 180º.

You could find two triangles with 90º 45º and 45º angles but with different-length sides.

Those would be congruent angles but not congruent triangles.

To find two positive real numbers whose product is a maximum, we need to use a mathematical technique called optimization. By solving the given equation and substituting the values back, we can find the two positive real numbers with a maximum product.

To find two positive real numbers whose product is a maximum, we need to use a mathematical technique called optimization. Let's define the two numbers as x and y.

Since the sum of the first number and three times the second number is 30, we can write the equation:

x + 3y = 30

To find the maximum product, we need to express the product of x and y in terms of a single variable. We can do this by substituting x = 30 - 3y into the product equation xy = (30 - 3y)y.

Now, we have a quadratic equation: y^2 - 10y + 15. Finding the maximum product corresponds to finding the vertex of this quadratic equation, which occurs when y = 5.

Substituting y = 5 back into the equation x + 3y = 30, we can solve for x: x + 3(5) = 30, x + 15 = 30, x = 15. Therefore, the two positive real numbers with a maximum product are x = 15 and y = 5.

Let us now tackle the problem!

This problem is about Kinematics.

Given:

vo = (-14.0i - 7.0j) m/s

a = (6.0i + 3.0j) m/s²

Unknown:

r = ? → v = 0 m/s

Solution:

To solve this problem, we need to use the following integral formula.

[tex]v = v_o + \int {a} \, dt[/tex]

[tex]v = (-14.0 \, \widehat{i} - 7.0 \, \widehat{j}) + \int {(6.0 \, \widehat{i} + 3.0\, \widehat{j})} \, dt[/tex]

[tex]v = (-14.0 + 6.0t) \, \widehat{i} + ( -7.0 + 3.0t ) \, \widehat{j}[/tex]

If the object comes to rest (momentarily) , then :

[tex]v_x = 0[/tex]

[tex](-14.0 + 6.0t) = 0[/tex]

[tex]6.0t = 14[/tex]

[tex]t = 14 \div 6.0[/tex]

[tex]\boxed {t = \frac {7}{3} ~ s}[/tex]

or

[tex]v_y = 0[/tex]

[tex]( -7.0 + 3.0t ) = 0[/tex]

[tex]3.0t = 7[/tex]

[tex]t = 7 \div 3.0[/tex]

[tex]\boxed {t = \frac {7}{3} ~ s}[/tex]

[tex]r = r_o + \int {v} \, dt[/tex]

[tex]r = 0 + \int { (-14.0 + 6.0t) \, \widehat{i} + ( -7.0 + 3.0t ) \, \widehat{j} } \, dt[/tex]

[tex]r = ( -14.0t + 3.0t^2 ) \, \widehat{i} + ( -7.0t + 1.5t^2 ) \, \widehat{j}[/tex]

At t = 7/3 s , then :

[tex]r = ( -14.0(\frac{7}{3}) + 3.0(\frac{7}{3})^2 ) \, \widehat{i} + ( -7.0(\frac{7}{3}) + 1.5(\frac{7}{3})^2 ) \, \widehat{j}[/tex]

[tex]r = [ (-16\frac{1}{3}) \, \widehat{i} + (-8\frac{1}{6}) \, \widehat{j} ] ~ m[/tex]

[tex]r \approx (-16.3 \, \widehat{i} - 8.2 \, \widehat{j} ) ~ m[/tex]

The behavior of the function f(x) as x becomes a very small negative number depends on the function's specific characteristics, such as decreasing values on a curve, a linear relationship, or asymptotic behavior.

When considering what happens to the function f(x) as x becomes a very small negative number, it depends on the behavior described by the function's equation. If the graph of the function shows a declining curve starting with a maximum at x = 0, as x becomes more negative, f(x) tends to decrease assuming that this behavior continues beyond the given graph. If the graph of f(x) shows a horizontal line between x = 0 and x = 20, this would typically indicate that for small negative values of x, the function would not be defined unless otherwise specified that the function's behavior extends with the same horizontal trend outside the given interval.

Situations such as the behavior of a spring force, described by a function like f(x) = -kx, might lead to a linear decrease as x becomes a small negative number, consistent with Hooke's Law. On the other hand, the presence of asymptotes would indicate that the function's value could grow without bounds as x approaches certain critical values, as seen in the case of a function like y = 1/x.

F(x) when x is a very small positive number then F(x) is a negative number with a small absolute value.

The correct option is (D).

The question shows a graph of a function[tex]\( f(x) \)[/tex]and asks what happens to[tex]\( f(x) \)[/tex] when [tex]\( x \)[/tex] is a very small negative number.

To answer this question, we do not need calculations but rather an interpretation of the graph. When [tex]\( x \)[/tex] is a very small negative number (approaching zero from the left), we need to look at the behavior of the graph as it approaches the y-axis from the left-hand side.

From the graph, it appears that as [tex]\( x \)[/tex] becomes a very small negative number (close to zero), [tex]\( f(x) \)[/tex] increases without bound. This suggests that[tex]\( f(x) \)[/tex]approaches positive infinity.

So, based on the graph, the answer would be:

[tex]\( f(x) \)[/tex] is a very large positive number.

This corresponds to option D on the multiple-choice answers provided.

To increase 72 by 130 percent, convert the percentage to a decimal (1.3), multiply 72 by this number to get 93.6, and then add it back to the original number to get the result of 165.6.

To calculate the result of increasing 72 by 130 percent, you multiply 72 by 130% (which is the same as 1.3 in decimal form) and then add it to the original number.

Calculation steps:

Convert the percentage increase to decimal form: 130% = 1.3.

Multiply the original number by this decimal: 72 × 1.3 = 93.6.

Add this value to the original number: 72 + 93.6 = 165.6.

Therefore, when you increase 72 by 130 percent, you get 165.6.

The graph resembles a "V" shape with its vertex at the origin.

The function f(x) = |x| - 1 is a piecewise function that represents the absolute value of x minus 1.

The absolute value function  |x| returns the distance of x from the origin on the number line.

When x is positive or zero, |x| = x , and when x is negative, |x| = -x.

Thus, f(x) = |x| - 1behaves differently for positive and negative values of x .

For [tex]\( x \geq 0 \)[/tex], the function is f(x) = x - 1, and for x < 0, the function is f(x) = -x - 1.

The graph of  f(x)  consists of two straight lines intersecting at the point (0, -1), with a slope of 1 for [tex]\( x \geq 0 \)[/tex] and a slope of -1 for x < 0.

The graph resembles a "V" shape with its vertex at the origin.
