Answer:

50 increased by 30% is 65

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

30% = 30/100 = 30 ÷ 100 = 0.3.

100% = 100/100 = 100 ÷ 100 = 1.

Percentage increase = 30% × 50

New value = 50 + Percentage increase

Calculate

New value =

50 + Percentage increase =

50 + (30% × 50) =

50 + 30% × 50 =

(1 + 30%) × 50 =

(100% + 30%) × 50 =

130% × 50 =

130 ÷ 100 × 50 =

130 × 50 ÷ 100 =

6,500 ÷ 100 =

65

Or just find 30% of 50 (15) and add that

The inverse of a power function of exponent n is a nth root radical function. For example, the inverse of y = 10x^2 is y = √(x/10) (at least for positive values of x and y).

The area of the semicircle is approximately 112.5π square meters.

To find the area of a semicircle, we will use the following terms: diameter, radius, and area.
Find the radius of the semicircle
Since the diameter is given as 30 meters, we can find the radius by dividing the diameter by 2:
Radius = Diameter/2 = 30 meters/2 = 15 meters.

Use the formula for the area of a circle and adjust it for a semicircle
The area of a full circle is given by the formula

\(A = \pi  \times  r^2,\)

where A is the area and r is the radius.

Since we are dealing with a semicircle (half of a circle), we will adjust the formula to find half the area of a full circle:
Semicircle Area\(= (1/2) \times \pi \times  r^2\)
Step 3: Calculate the area of the semicircle
Substitute the radius value (15 meters) into the formula:
Semicircle Area \(= (1/2) \times  \pi  \times (15 meters)^2\)
Semicircle Area \(\approx (1/2) \times \pi \times  225\) square meters \(\approx  112.5 \times \pi\) square meters.

Let's calculate the total cost of all the items purchased by the computer club:

Cost of 14 portfolios = 14 * $24.59

Cost of 14 binders = 14 * $12.92

Cost of 14 school sweatshirts = 14 * $14.00

Cost of 14 music cases = 14 * $1.25

Cost of 14 phone cases = 14 * $1.99

Cost of 14 mouse pads = 14 * $2.14

Total cost of all items = Cost of 14 portfolios + Cost of 14 binders + Cost of 14 school sweatshirts + Cost of 14 music cases + Cost of 14 phone cases + Cost of 14 mouse pads

Plugging in the given values:

Total cost of all items = (14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14)

Now, the computer club will pay for 40% of the total cost. To calculate this, we can multiply the total cost by 40% (or 0.40):

Club's payment = 0.40 * Total cost of all items

The remaining cost will be divided equally among the 14 members:

Remaining cost per member = (Total cost of all items - Club's payment) / 14

Plugging in the values and calculating:

Club's payment = 0.40 * ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14))

Remaining cost per member = ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14) - Club's payment) / 14

So, each member of the computer club will owe the calculated value for "Remaining cost per member".

A graph which represents the overall equation (inequality) represented by this scenario is shown in the image attached below.

A graph can be defined as a type of chart that is commonly used for the graphical representation of data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis).

Let the variable x represent the total number of guests.

Let the variable y represent the amount of meat

Next, we would write an inequality that represents an amount of meat that must be 2 pounds fewer than one-third (1/3) the total number of guests. Since the customer decides they want at least that amount of meat, the inequality symbol that must be used is greater than (>).

y > 1/3(x) + 2

y > x/3 + 2

In conclusion, the y-value for this inequality graph (see attachment) intersects the x-axis at 0 and 6 with the boundary line shaded upward and dashed to indicate that it is not part of the solution, which must be represented with a greater than (>) inequality symbol.

Step-by-step explanation:

The area of  region enclosed in line y=mx and curve y=x/(x^2 1) is  \(ln(m \sqrt{(1/m^2 - 1))\)- m/2 (1/m^2 - 1) square unit.

The line y = mx intersects the curve y = x/(x^2 + 1) at two points, say (a, ma) and (b, mb), where a < b. Setting mx = x/(x^2 + 1), we can solve for x to get x = mx / (1 - m^2 x^2), or equivalently, (1 - m^2 x^2)x = mx, which gives x = 0 (when m = 0) or x^2 = 1/m^2 - 1, or equivalently, x = ±\(\sqrt{(1/m^2 - 1)\). Since the line is symmetric about the origin, we can assume m > 0.

For the line to enclose a region with the curve, we must have a < 0 < b, which means the intersection points are (- \(\sqrt{(1/m^2 - 1)\), - m \(\sqrt{(1/m^2 - 1)\)).  and\(\sqrt{(1/m^2 - 1)\), m \(\sqrt{(1/m^2 - 1)\)). The area of the enclosed region is then:

∫_-\(\sqrt{(1/m^2-1)^\sqrt{(1/m^2-1)\)[x/(x^2+1) - mx] dx

We can use partial fraction decomposition to write x/(x^2+1) as 1/2 [1/(x-i) - 1/(x+i)], where i = sqrt(-1), and then integrate term by term to get:

∫_-\(\sqrt{(1/m^2-1)^\sqrt{(1/m^2-1)\) [x/(x^2+1) - mx] dx

= 1/2 [ln(x-i) - ln(x+i) - m/2 x^2] |_ - \(\sqrt{(1/m^2-1)^\sqrt{(1/m^2-1)\)

= ln(\(m \sqrt{(1/m^2 - 1))\) - m/2 (1/m^2 - 1)

Therefore, the area of the enclosed region is \(ln(m \sqrt{(1/m^2 - 1))\)- m/2 (1/m^2 - 1) square unit. This expression is undefined when m <= 1 or m >= -1, since in those cases, the curve and line do not intersect.

The mean of the probability distribution is μ = 118.

We are given that a random variable x has a normal distribution with standard deviation σ = 25, and the probability that x exceeds 150 is 0.90. We need to find the mean of the probability distribution, denoted by μ.

Using the properties of the standard normal distribution, we can convert the given probability to a z-score:

P(x > 150) = 0.90

z = (150 - μ) / σ

From standard normal distribution tables or a calculator, we can find the z-score that corresponds to a probability of 0.90, which is approximately 1.28.

Substituting these values into the z-score formula and solving for μ, we get:

1.28 = (150 - μ) / 25

Multiplying both sides by 25, we get:

32 = 150 - μ

Subtracting 150 from both sides, we get:

-118 = -μ

Dividing both sides by -1, we get:

μ = 118

Therefore, the mean of the probability distribution is μ = 118.

The expected value of n ( a random variable that corresponds to your net winnings in dollars ) is :

-$4.83

To find the expected value of n, we need to calculate the product of each possible outcome (1, 2, 3, 4, 5, 6) with its corresponding probability and sum them up.

The probability of each outcome is equal since each outcome is equally likely. Therefore, the probability of each outcome is 1/6.

Using this information, we can calculate the expected value of n as follows:

Expected value of n = (1/6)($1)^2 + (1/6)($2)^2 + (1/6)($3)^2 + (1/6)($4)^2 + (1/6)($5)^2 + (1/6)($6)^2 - $20

Expected value of n = (1/6)(1) + (1/6)(4) + (1/6)(9) + (1/6)(16) + (1/6)(25) + (1/6)(36) - $20

Expected value of n = 15.17 - $20

Expected value of n = -$4.83

Therefore, the expected value of n is -$4.83. This means that on average, you are expected to lose $4.83 for every game you play.

The given expression (-3. 8)+0+y would yield the following values, if evaluated for the mentioned values of y. If y = -3.3, the value is -7.1, If y = -7.1, the value is -10.9 , If y = -2.6, the value is -6.4 , If y = 1, the value is -2.8. and If y = 4.2, then the value is 0.4.

To evaluate the funtion (-3.8) + 0 + y for the given values of y, we substitute the values of y one by one and simplify:

In order to calculate  y = -3.3, putting the values of y in the given expression,

= (-3.8) + 0 + (-3.3) = -7.1

Now for y = -7.1, the expression can be evaluated as

=(-3.8) + 0 + (-7.1) = -10.9

For the calculation of y = -2.6,

=(-3.8) + 0 + (-2.6) = -6.4

Calculating y = 1, we will get,

=(-3.8) + 0 + 1 = -2.8

And finally for y = 4.2

= (-3.8) + 0 + 4.2 = 0.4

Therefore, the resultant values of the expression (-3.8) + 0 + y for the given values of y are:

For y = -3.3, the value is -7.1.

For y = -7.1, the value is -10.9.

For y = -2.6, the value is -6.4.

For y = 1, the value is -2.8.

For y = 4.2, the value is 0.4.

Answer:

a) $26

b) 24.07%

c) $94.3

Step-by-step explanation:

Given that:

Before tax:

Normal price of dress = $62

Discounted price of dress = $48

Normal price of a pair of shoes = $46

Discounted price of a pair of shoes = $34

a) Before the sales tax, total savings = ($64 - $48) + ($46 - $34) = $26

b) Total percentage discount on total sales.

Total bill for original price = $62 + $46 = $108

Percentage discount can be found by the formula:

\(\dfrac{\text{Total discount}}{\text{Total bill for original price}}\times 100\\\Rightarrow \dfrac{26}{108} \times 100 = 24.07\%\)

c) Total amount paid if the sales tax is 15%.

Amount paid with tax = Amount after discount + 15% of amount after discount

Amount after discount = $48 + $34 = $82

15% of $82 = $18.29

Amount paid with sales tax = $82 + $12.3 = $94.3
