The value of x, which represents the cost of each carton of ink is $63.

Let's break down the given information:

The subscription fee for the printer ink service is $230.

The company paid a total of $1364, which includes the subscription fee.

The company purchased 18 cartons of ink.

To find the value of x, we need to determine the cost of the ink cartridges alone, excluding the subscription fee. We can subtract the subscription fee from the total payment to get the cost of the ink:

Total payment - Subscription fee = Cost of ink cartridges

$1364 - $230 = $1134

Now, we divide the cost of the ink cartridges by the number of cartridges to find the cost per cartridge:

Cost of ink cartridges / Number of cartridges = Cost per cartridge

$1134 / 18 = $63

Therefore, the value of x, which represents the cost of each carton of ink, is $63.

A. -10x^2 - 3x +4 , is the expression is equal to f(x) + g(x).

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

f(x)= -3x^2+4x+4

g(x)= x(-7x-7)

now,

f(x) + g(x)

=-3x^2+4x+4 +x(-7x-7)

= -10x^2 - 3x +4

Hence, A. -10x^2 - 3x +4 , is the expression is equal to f(x) + g(x).

(a) Sketching the respective stress-strain curves for the hard and brittle steel and the soft and ductile steel:

Hard and Brittle Steel:

The stress-strain curve for hard and brittle steel typically shows a steep linear elastic region followed by a sudden drop in stress and limited plastic deformation before fracture. The curve would have a high modulus of elasticity and a low strain at failure.

Soft and Ductile Steel:

The stress-strain curve for soft and ductile steel exhibits a more gradual linear elastic region, followed by a yield point, significant plastic deformation, and necking before ultimate failure. The curve would have a lower modulus of elasticity and a higher strain at failure compared to the hard and brittle steel.

(b) Quantifying brittleness/ductility:

Brittleness and ductility can be quantified using different mechanical properties:

Brittleness:

Brittleness is often measured by the fracture toughness or the ability of a material to resist crack propagation. It is commonly represented by parameters such as the critical stress intensity factor (KIC) or the fracture toughness (KIC = σ√πc), where σ is the applied stress and c is the crack length.

Ductility:

Ductility is typically measured by the elongation or strain at failure. It is represented by the engineering strain (ε = ΔL/L0), where ΔL is the change in length and L0 is the original length of the specimen. The greater the elongation or strain at failure, the higher the ductility of the material.

To quantify brittleness/ductility, these parameters can be determined experimentally using specialized tests such as fracture toughness tests or tensile tests. By comparing the values obtained for different materials, their relative brittleness or ductility can be assessed.

Measurements on an ordinal scale offer additional information by providing an ordered arrangement of categories or variables, enabling comparisons and understanding of relative positions or preferences.

Measurements on an ordinal scale provide additional information compared to measurements on a nominal scale by allowing for the establishment of a ranking or order among the measured categories or variables. While a nominal scale categorizes data into distinct groups without any inherent order, an ordinal scale assigns a specific order or hierarchy to the categories or variables being measured.

With measurements on an ordinal scale, it becomes possible to determine the relative position, preference, or level of a particular category or variable in relation to others. This ordering provides more nuanced information about the data, allowing for comparisons such as "greater than" or "less than" relationships. However, the precise magnitude or interval between categories is not defined in an ordinal scale, unlike in other scales like interval or ratio scales.

According to the approximation, the critical value of χ^2 for this scenario is approximately 2799.93.

To test the claim that males have a standard deviation greater than the standard deviation of 7460 words for females, we can perform a right-tailed hypothesis test using the chi-square distribution.

Given:

Sample size of males (n) = 68

Sample standard deviation of males (s) = 7884 words

Standard deviation of females (σ) = 7460 words

Significance level (α) = 0.01

Degrees of freedom (df) = n - 1 = 68 - 1 = 67

To estimate the critical value of χ^2, we'll use the approximation formula:

χ^2 ≈ 21√(z + 2k - 1)^2

Here, k is the number of degrees of freedom (67) and z is the critical value obtained from technology or a standard normal distribution table. In this case, z = 2.33 is given.

Substituting the values into the formula:

χ^2 ≈ 21√(2.33 + 2(67) - 1)^2

≈ 21√(2.33 + 132 - 1)^2

≈ 21√(133.33)^2

≈ 21 * 133.33

≈ 2799.93

According to the approximation, the critical value of χ^2 for this scenario is approximately 2799.93.

Comparing this estimate to the critical value of χ^2 = 96.828 obtained by using Statdisk and Minitab, we see that they are significantly different. The estimate obtained using the approximation method is much larger than the critical value obtained from Statdisk and Minitab.

Answer:

124

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180:

m<R + m<S + m<T = 180

11x + 3 + x + 15 + 2x + 8 = 180 add like terms

14x + 26 = 180 subtract 26 from both sides

14x = 154 divide both sides by 14

x = 11 to find m<R replace x with 11

11*11 + 3 = 124

Apply angle sum property

\(\\ \rm\rightarrowtail 11x+3+x+15+2x+8=180\)

\(\\ \rm\rightarrowtail 14x+26=180\)

Answer:

Step-by-step explanation:

The expected value of each game for the player is $2.50.

In this game, a player pays $3 to play and rolls a standard six-sided die.

The expected value of each game can be calculated by finding the probabilities of each outcome and their respective payouts.

There are 3 even numbers (2, 4, 6) and 3 odd numbers (1, 3, 5) on a six-sided die.

The probability of rolling an even number is 3/6 (or 1/2) and the probability of rolling an odd number is also 3/6 (or 1/2).

If a player rolls an even number, they receive $6. If they roll an odd number, they receive $5.

To calculate the expected value, multiply the probability of each outcome by its payout:

(1/2 * $6) + (1/2 * $5) = $3 + $2.50 = $5.50

Since the player pays $3 to play, the expected value for the player is:

$5.50 - $3 = $2.50

Using unit value, Kelly earned a total of $87.55 this week.

In most cases, the unit value is obtained by dividing the cost or value of a group of objects by the total number of items.

The appraisal of a single item or component within a group is known as unit value. The concept of unit value is applicable in a variety of contexts, including building, inventory control, sales, and stock trading. The unit value is typically the result of dividing the price or worth of a set of things by the total number of items.

Kelly delivered three packages on Monday, five on Wednesday, and nine on Saturday in light of this.

There have been 17 shipments delivered in all.

\(x=\dfrac{3}{2}\pi +2 \pi n\)

\(x=\dfrac{1}{6}\pi+2 \pi n\)

\(x=\dfrac{5}{6}\pi+2 \pi n\)

Step-by-step explanation:

Given trigonometric equation:

\(\sin x \cos x &= \dfrac{1}{2} \cos x\)

Rearrange the equation so that it equals zero:

\(\begin{aligned}\sin x \cos x &= \dfrac{1}{2} \cos x\\2 \sin x \cos x &= \cos x\\2 \sin x \cos x - \cos x &=0\\ \cos x (2 \sin x - 1)&=0\end{aligned}\)

Case 1

\(\begin{aligned}\cos x &=0\\x&=\cos^{-1}(0)\\x&=\dfrac{1}{2} \pi +2\pi n, \; \dfrac{3}{2}\pi +2 \pi n\end{aligned}\)

Case 2

\(\begin{aligned}2\sin x - 1& = 0\\2 \sin x & = 1\\\sin x & = \dfrac{1}{2}\\x&=\sin^{-1}\left(\dfrac{1}{2}\right)\\x & = \dfrac{1}{6} \pi+2 \pi n, \; \dfrac{5}{6} \pi +2 \pi n\end{aligned}\)
