Using the standard form of the equation of line, the slope of the line represented by the equation 3x-4y=7 is 3/4.

In the given question,

We have to find the slope of the line represented by the equation 3x-4y=7.

The given equation is 3x-4y=7.

To find the slope we first express the given equation in the form of standard equation of line.

The standard form of equation is y=mx+c where m is slope of the equation.

Now expressing the equation in standard form.

3x-4y=7

Subtract 3x on both side

3x-4y-3x=7-3x

-4y=7-3x

Divide by -4 on both side

-4/-4 y=7/-4 - (-3)/(-4) x

Simplifying

y=3/4x-7/4

Now comparing from the standard equation to find the slope(m).

m = 3/4

Hence, the slope of the line represented by the equation 3x-4y=7 is 3/4.

The starting price of the toys was $7.50.

What is addition?

Addition is a basic arithmetic operation that combines two or more numbers to get a sum or a total. It is represented by the "+" symbol. When we add numbers, we are finding the total amount when we combine them.

Let's assume the starting price of the toys as "x".

After the first hour, the price of the toys will be "x - 0.25".

After the second hour, the price of the toys will be "x - 0.25 - 0.25 = x - 0.5".

Similarly, after the third hour, the price of the toys will be "x - 0.75".

We can see that the price of the toys decreases by $0.25 every hour. So, after the 8th hour, the price of the toys will be:

x - (0.25 + 0.25 + 0.25 + 0.25 + 0.25 + 0.25 + 0.25 + 0.25)

= x - (8 x 0.25)

= x - 2

We know that after the 8th hour, the price of the toys is $5.50. So we can write:

x - 2 = 5.50

Adding 2 to both sides:

x = 7.50

Therefore, the starting price of the toys was $7.50.

Loretta would not have paid any taxes last year because her total earnings were below the €8625 threshold.

What is Percentage ?

A Percentage is a figure or ratio that is stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

The total amount paid in tax from Cary's last year earning is £9640
Total earning last year = €34 500

Tax on earnings :
First €3500 = 0%
€3500 to €10 500 = 25%
Earnings above €10 500 = 35%
Therefore, tax paid on €34 500 :

Tax percentage × amount earned

First €10 500 earned = (25% × 10,500) = 2625

Excess above €10 500 = (34500 - 10500) = 24000

25% × 24000 = 6000

The main difference between the denominator of the F-ratio (the error term) for a repeated-measures ANOVA and an independent-measures ANOVA lies in the way variability is accounted for within the groups.

In a repeated-measures ANOVA, the same participants are exposed to multiple conditions or measured at different time points. Therefore, this design accounts for individual differences, leading to a smaller error term in the denominator of the F-ratio.

The error term in repeated-measures ANOVA represents the variability due to individual differences and the residual error, but not the variability between participants. In contrast, an independent-measures ANOVA involves separate groups of participants for each condition, meaning that variability between participants is included in the error term.

As a result, the error term for the independent-measures ANOVA is larger than that of the repeated-measures ANOVA. This difference in the denominator of the F-ratio affects the sensitivity of the statistical test, with the repeated-measures ANOVA being more sensitive due to its smaller error term.

In summary, the denominator of the F-ratio (the error term) differs for a repeated-measures ANOVA compared to an independent-measures ANOVA in terms of the variability accounted for within groups. The repeated-measures ANOVA error term is smaller, as it controls for individual differences, while the independent-measures ANOVA error term is larger because it includes variability between participants.

According to the Central Limit Theorem, for a sufficiently large sample size, the distribution of sample means will be approximately normal, regardless of the shape of the population distribution.

To calculate the probability, we need to convert the sample mean score to a z-score and then find the corresponding area under the standard normal distribution curve.

Calculate the standard error of the mean (SE):

SE = σ / sqrt(n)

SE = 127 / sqrt(72)

SE ≈ 14.96

Calculate the z-score:

z = (X - μ) / SE

z = (567 - 572) / 14.96

z ≈ -0.334

Find the probability corresponding to the z-score:

We can find the area to the left of the z-score -0.334. Let's denote this probability as P(z < -0.334).

The probability that the sample mean score is less than 567 is approximately equal to P(z < -0.334).

The following system of equation can be solved by first substituting the dependent variable in the other equation . The solution yields x = -1.5 and y = 6.5 .

The two equations are given as -

4x-2y=7

3x-3y=15

First substituting the value of x from the first equation and then putting that value in the second equation for the following system of equation.

From first equation,

⇒ 4x = 7 + 2y

∴  x = (7 + 2y)/4

Putting this value of x in second equation,

⇒ 3*(7 + 2y)/4 - 3y = 15

⇒ 3*(7 + 2y) - 12y = 60

⇒ 21 + 6y - 12y = 60

⇒ -6y = 39

∴  y = -6.5

∴ x = (7 + 2y)/4 = -1.5

Thus x = -1.5 and y = -6.5

The projection Proj,u of vector v onto vector u in the weighted Euclidean inner product space is (-1.13, -0.57).

The projection Proj,u of vector v onto vector u in the weighted Euclidean inner product space is calculated using the formula:

Proj,u = ((v⋅u) / (u⋅u)) * u

In this case, u = (-2.3) and v = (4, 2). The dot product of u and v is (4 * -2.3) + (2 * -2.3) = -9.2 + -4.6 = -13.8. The dot product of u and itself is (-2.3 * -2.3) = 5.29.

Therefore, the projection Proj,u of vector v onto vector u is ((-13.8 / 5.29) * -2.3, (-13.8 / 5.29) * -2.3) = (-1.13, -0.57).

The projection Proj,u of vector v onto vector u in the weighted Euclidean inner product space is (-0.794, -0.397).

In order to find the projection Proj,u, we need to compute the scalar projection of vector v onto vector u and then multiply it by the unit vector of u. The scalar projection is given by the formula:

proj_scalar = (v · u) / (u · u)

where "·" represents the inner product operation. In this case, we have w = (3, 2), u = (-2.3), and v = (4, 2).

To compute the inner product, we use the weighted Euclidean inner product defined as follows:

(u, v)w = (u · v) + w

where w = (3, 2). Therefore, the inner product of u and v becomes:

(u, v)w = (-2.3 × 4 + 0 × 2) + (3 × 4 + 2 × 2) = -9.2 + 16 = 6.8

Next, we calculate the inner product of u with itself:

(u, u)w = (-2.3 × -2.3 + 0 × 0) + (3 × 3 + 2 × 2) = 5.29 + 13 = 18.29

Now we can compute the scalar projection:

proj_scalar = (6.8) / (18.29) = 0.3716

Finally, we multiply the scalar projection by the unit vector of u:

Proj,u = proj_scalar × (u / ||u||) = 0.3716 × (-2.3 / ||-2.3||) = (-0.794, -0.397)

Time taken by mark to travel 5000 feet, 20 minutes.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Mark lives 5,000 feet from the school.

Since He walks to school at a steady rate of 250 feet per minute.

Thus,

Time is taken by mark to travel 250 feet  = 1 minute

So, Time taken by mark to travel 1 foot = 1/250 minute

Thus,

Time is taken by mark to travel 5000 feet  = 1/250 * 5000 minute

Time is taken by mark to travel 5000 feet  = 20 minutes
