Please can someone help me I will answer one of your questions that you are stuck on thanks xx

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".

Hope this is good

Answer:

You can use grid method.

That is easy.

Answer:

(f*g)(x) = 4x⁵ - 16x³ + x² - 4

Step-by-step explanation:

To find (f*g)(x), you need to multiply f(x) with g(x).  Use FOIL to multiply.

f(x) = 0.5x² - 2

g(x) = 8x³ + 2

(f*g)(x) = (0.5x² - 2)(8x³ + 2)

(f*g)(x) = 4x⁵ + x² - 16x³ - 4

(f*g)(x) = 4x⁵ - 16x³ + x² - 4

(A) qualitative and quantitative categories. (A) True. (C) is highly susceptible when used outside tested range of X values.

Data is broken into (A) qualitative and quantitative categories, which refers to the nature of the data being analyzed. Qualitative data is non-numeric and describes characteristics or attributes, while quantitative data is numeric and describes quantities or measurements.

The statistical calculation r shows the correlation between variables (Y, X) in a regression analysis. This statement is true. The correlation coefficient r is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.

Linear regression used for estimation of A is susceptible when used outside the tested range of X values. This statement is true. Linear regression models are based on the assumption of a linear relationship between the dependent variable Y and the independent variable X within a certain range of X values. When used outside of this range, the linear regression model may not accurately predict the values of Y. This is because the linear relationship between Y and X may not hold outside of the tested range, or other factors may come into play that were not accounted for in the model. Therefore, it is important to carefully consider the range of X values used in the regression analysis and to exercise caution when making predictions outside of this range.

Answer:

0.0421

Step-by-step explanation:

We solve using the z score formula

z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean = μ = 8.9 pounds

σ is the population standard deviation = σ = 1.1 pounds

For x < 7 pounds

z = 7 - 8.9/1.1

= -1.72727

Probability value from Z-Table:

P(x<7) = 0.042059

The sum of the shares of seun and dayo is n80.00.

A ratio shows how frequently a number encompasses another. If you have eight oranges and six lemons in a fruit plate, the orange-to-lemon ratio is eight to six. Similarly, the orange-lemon ratio is 6:8, and the orange-to-total fruit ratio is 8:14.

Given that,

Seun, tayo and dayo are to share n = 120 in the ratio 4:3:2 respectively.

Here n = 120

Seun ,tayo and dayo = 4:3:2

Seun shares = 120 × \(\frac{4}{9}\)

seun shares = 120 × 0.44

seun shares = 53.33

dayo shares = 120 × \(\frac{2}{9}\)

dayo shares = 120 × 0.22

dayo shares = 26.67

Sum of the shares of seun and dayo is 53.33 + 26.67

well, since the y-intercept is at -5, or namely when the line hits the y-axis is at -5, that's when x = 0, so the point is really (0 , -5), and we also know another point on the line, that is (-1 ,6), to get the equation of any straight line, we simply need two points off of it, so let's use those two

\(\stackrel{y-intercept}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{-5})}\qquad (\stackrel{x_2}{-1}~,~\stackrel{y_2}{6}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{(-5)}}}{\underset{run} {\underset{x_2}{-1}-\underset{x_1}{0}}} \implies \cfrac{6 +5}{-1} \implies \cfrac{ 11 }{ -1 } \implies - 11\)

Por lo tanto, el precio final con descuento e IVA incluido será de $22,673.75.

El impuesto al valor agregado (IVA) en la franja fronteriza es del 8%. Por lo tanto, para calcular cuánto se pagará de IVA por un equipo de cómputo de $23,589.00, se debe multiplicar el valor del equipo por el porcentaje del IVA:

$23,589.00 x 0.08 = $1,887.12

Por lo tanto, se pagará $1,887.12 de IVA.

Para calcular el total a pagar, se debe sumar el valor del equipo y el valor del IVA:

$23,589.00 + $1,887.12 = $25,476.12

Por lo tanto, el total a pagar será de $25,476.12.

Si el equipo cuenta con un descuento del 11%, se debe restar el valor del descuento al precio original del equipo:

$23,589.00 x 0.11 = $2,594.79 (descuento)

$23,589.00 - $2,594.79 = $20,994.21 (precio con descuento)

Para calcular el valor del IVA sobre el precio con descuento, se multiplica el precio con descuento por el porcentaje del IVA:

Answer:

cos W = 7/15

Step-by-step explanation:

Mathematically the cosine of an angle is the ratio of the adjacent to the hypotenuse side

From the diagram given, 14 is adjacent to vertex w and 30 faces the right angle which makes it the hypotenuse

So, we have it that;

cos W = 14/30

cos W = 7/15

The composite Simpson’s rule approximates the integral by applying Simpson’s rule to each of these m sub-intervals and adding up the results. So, T1,m corresponds to the composite Simpson's rule.

Given: T1, m defined in (6.32). To,

m+1-To, 0,

m 1 1 – SN

(f) = N-1 N-1 h 1 { f(x) + f(xXx) + 2 Σ¹ f(x) + 4*Σ* ƒ((x₂ + x + 1)/2) 6 j

=1 j

=0

To show: T1, m corresponds to the composite Simpson's rule

Formula for Simpson's rule for n=2, f(x) is a function on [a, b], and h = (b − a)/2:S2(f) = h/3 [f(a) + 4f((a + b)/2) + f(b)]

Here, the interval [a,b] is partitioned into two intervals of equal length and the composite Simpson’s rule approximates the integral by applying Simpson’s rule to each of the sub-intervals and adding up the results.So,T1,m can be rewritten as (6.32):

T1,m = h/3 [ f(x0) + 4f(x1/2) + 2f(x1) + 4f(3/2) + ... + 2f(xm-1) + 4f(xm-1/2) + f(xm)]                

 = (h/3) [f(x0) + 4f(x1/2) + 2f(x1) + 4f(3/2) + ... + 2f(xm-1) + 4f(xm-1/2) + f(xm)]

Here, we can see that m sub-intervals of the form [xi-1, xi] are formed by the partition of the interval [a,b] into m sub-intervals. Each sub-interval has a length of h = (b − a)/m = x1 − x0. The composite Simpson’s rule approximates the integral by applying Simpson’s rule to each of these m sub-intervals and adding up the results. So, T1,m corresponds to the composite Simpson's rule.

There were 140 children and 145 adults admitted to the amusement park.

The number of children admitted is represented by 'c' and the number of adults admitted is represented by 'a'.

The admission fee for children is $5.50, and the admission fee for adults is $14.00.

We know that the total number of people admitted is 285, and the total admission fees collected is $2,800.00.

Equation for the total number of people admitted

c + a = 285 ...(1)

Equation for the total admission fees collected)

5.50c + 14.00a = 2800 ...(2)

From equation 1, we can express c in terms of a:

c = 285 - a

Substituting this value of c in equation 2:

5.50(285 - a) + 14.00a = 2800

1567.50 - 5.50a + 14.00a = 2800

8.50a = 2800 - 1567.50

a = 145.29

a = 145

Substituting this value of a in equation 1 to find c:

c + 145 = 285

Two-person, non-zero sum games can have a single unique Nash equilibrium in pure strategy, such as the Prisoner's Dilemma, or multiple Nash equilibria in pure strategy, like the Battle of the Sexes.

Example of a two-person, non-zero sum game with a single unique Nash equilibrium in pure strategy:

Prisoner's Dilemma:

Player 1 options: Cooperate (C) or Defect (D)

Player 2 options: Cooperate (C) or Defect (D)

        | Player 2 Cooperate | Player 2 Defect |

----------------------------------------------

Player 1 |      (-1, -1)      |    (-3, 0)     |

----------------------------------------------

Player 2 |       (0, -3)      |    (-2, -2)    |

In this game, both players have a dominant strategy to defect (D) regardless of the other player's action. The Nash equilibrium is (D, D) since neither player can unilaterally deviate to improve their payoff.

Example of a two-person, non-zero sum game with multiple Nash equilibria in pure strategy:

Battle of the Sexes:

Player 1 options: Opera (O) or Football (F)

Player 2 options: Opera (O) or Football (F)

        | Player 2 Opera | Player 2 Football |

----------------------------------------------

Player 1 |    (2, 1)     |      (0, 0)      |

----------------------------------------------

Player 2 |    (0, 0)     |      (1, 2)      |

In this game, there are two pure strategy Nash equilibria: (O, O) and (F, F). Each player prefers a different outcome, but both players agree on their preferred action at each Nash equilibrium.

From the question, we are to determine the values of the missing sides

From the diagram,

Opposite = 9

Adjacent = y

Hypotenuse = x

Included angle = 45°

Using SOH CAH TOA, we can write that

\(tan 45^\circ= \frac{9}{y}\)

\(1 = \frac{9}{y}\)

∴ y = 9

Since the triangle is a right triangle, we can write that

x² = y² + 9² (Pythagorean theorem)

x² = 9² + 9²

x² = 81 + 81

x² = 162

x = √162
