Make ‘y’ the subject of the formula

w = x^2 - 2yz

At the bicycle manufacturer, the average cost per bicycle is $77.

To find the average cost per bicycle, we need to find the total cost of making all three bicycles and divide that by the number of bicycles.

The total cost is of the bicycles is given by -

$72 (cost of first bicycle) + $83 (cost of second bicycle) + $77 (cost of third bicycle) = $232

Now to find the average cost per bicycle, we will divide the total cost by the number of bicycles.

Hence, $232 ÷ 3 = $77

Therefore, the average cost per bicycle is $77.

Answer:

We can use proportion to estimate the number of households that have a dog in the town of Nowaday.

From the data given in the random sample, we know that 24 out of 60 households had a dog. This can be written as:

24/60 = x/3000

where x is the number of households in the town that have a dog.

To solve for x, we can cross-multiply and simplify:

24 x 3000 = 60 x x

x = (24 x 3000) / 60

x = 1,200

Therefore, we can estimate that approximately 1,200 households in the town of Nowaday have a dog.

The coordinates of X that partitions XY in the ratio 5 to 4 include the following: X (-1.6, -7).

In this scenario, line ratio would be used to determine the coordinates of the point X on the directed line segment AB that partitions the segment into a ratio of 5 to 4.

In Mathematics and Geometry, line ratio can be used to determine the coordinates of X and this is modeled by this mathematical equation:

M(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

By substituting the given parameters into the formula for line ratio, we have;

M(x, y) = [(5(2) + 4(-6))/(5 + 4)],  [(5(-11) + 4(-2))/(5 + 4)]

M(x, y) = [(10 - 24)/(9)],  [(-55 - 8)/9]

M(x, y) = [-14/9],  [(-63)/9]

The amount of radioactive material left after half a day = 0.4883 g

Let us assume that function f(x) represents the amount of radoactive material and x represents the time in hour.

Initially the amount of radioactive material is a = 2000 g

A material decays by half every every hour.

This means that the rate of decay  = 1/2

So, we get an exponential decay function as:

f(x) = 2000 (1/2)^x

We need to find the amount of material after half a day.

The number of hours in half a day = 12

This means that we need to find the value of f(x) for x = 12

f(x) = 2000 × (1/2)¹²

f(x) = 0.4883 g

Therefore, the amount of  material is left = 0.4883 g

Step-by-step explanation:

The predicted value of the tip amount if when bill $100 is $15.80

The value of r, the correlation coefficient, can be found using a calculator. After calculating the values, the correlation coefficient between the bill amount and tip amount is approximately 0.939.

To calculate the correlation coefficient (r), the sum of the products of the standardized bill amounts and tip amounts, as well as the square roots of the sums of squares of the standardized bill amounts and tip amounts, need to be calculated.

These calculations are performed for each data point. Then, the correlation coefficient can be obtained using the formula:

r = (n * ∑(x * y) - ∑x * ∑y) / √((n * ∑(x^2) - (∑x)^2) * (n * ∑(y^2) - (∑y)^2))

Yes, there is a linear correlation between the bill amount and tip amount. The correlation coefficient of 0.939 indicates a strong positive linear relationship.

This means that as the bill amount increases, the tip amount tends to increase as well.

To find the linear regression equation, we can use the least squares method.

The equation represents the line of best fit that minimizes the sum of squared differences between the actual tip amounts and the predicted tip amounts based on the bill amounts.

Using a calculator, the linear regression equation is found to be:

Tip ($) = 0.176 * Bill ($) + 3.041.

To predict the tip amount if the bill was $100, we can substitute the bill amount into the linear regression equation. Plugging in $100 for the bill amount, we have:

Tip ($) = 0.176 * 100 + 3.041.

Calculating the expression, we find that the predicted tip amount would be approximately $19.64.

There are 24 adult-sized shirts in the Order.

The number of adult-sized shirts in the order, we need to calculate two-fifths of the total number of shirts and subtract it from the total.

Given that the order consists of 40 shirts and two-fifths of the shirts are children-sized, we can calculate the number of children-sized shirts as follows:

Children-sized shirts = (2/5) * 40

                    = (2/5) * 40

                    = 16

Since the remaining shirts are adult-sized, we can find the number of adult-sized shirts by subtracting the number of children-sized shirts from the total number of shirts:

Adult-sized shirts = Total shirts - Children-sized shirts

                 = 40 - 16

                 = 24

Therefore, there are 24 adult-sized shirts in the order.

Given

A semi-circle is placed over a rectangle

width of the rectangle is w=1.5 cm

The length of the rectangle is l=9.2 cm

from the figure, we can write

\(\Rightarrow 9.2=2.5+2r\quad (\text{length of rectangle is equal})\)

where r=radius of the semi-circle

\(\Rightarrow 2r=6.7\\\Rightarrow r=3.35\ cm\)

Perimeter of figure

\(\Rightarrow 9.2+1.5+2.5+\pi r+1.5\\\Rightarrow 14.7+10.52=25.22\ cm\)

Area of the figure

\(\Rightarrow A=\text{Area of rectangle+Area of semi-circle}\\\Rightarrow A=1.5\times 9.2+\pi \times 3.35^2\\\Rightarrow A=13.8+35.26=49.06\ cm^2\)

The correct option is;

Choice A 4·(n - 3) - 6·n

Step-by-step explanation:

The given expression is

Which gives;-6·n+(-12)+4·n

- 12 + 4·n-6·n = -2·n - 12 = - (2·n + 12)

The options given are Choice A and/or Choice B;

(Choice A) 4·(n - 3) - 6·n

Which can be simplified as follows;

4·(n - 3) - 6·n = 4·n - 12 - 6·n

Which gives;

4·n - 12 - 6·n = 4·n  - 6·n- 12 = -2·n - 12 = -(2·n + 12)

Therefore, 4·(n - 3) - 6·n is equivalent to -6·n+(-12)+4·n

For choice B, we have;

2·(2·n - 6) which gives;

2·(2·n - 6) = 4·n - 12

Therefore, 2·(2·n - 6) is not equivalent to -6·n+(-12)+4·n

Which gives the correct option as Choice A.

Let D be the region bounded by the lines y = 1, y = 2, x = 0, and x = x. In order to express the double integral as an iterated integral with reversed order of integration, we first need to sketch the region D.

\(\int\limits^x_0\int\limits^2_1 f(x,y) dydx\)

The region is bounded by the lines y = 1, y = 2, x = 0, and x = x. This forms a triangle-like shape with 1 and 2 being the x-coordinates of the vertices and x = 0 being the base of the triangle. Then, we can express the double

integral as: \(\int\limits^x_0\int\limits^2_1 f(x,y) dydx\)where the order of integration is reversed from the original double integral. This means that first we are integrating with respect to y from 0 to x, and then we are integrating with respect to x from 1 to 2.

Therefore,

∫10∫1∫ ∫01∫x1∫xy dzdydx as an iterated integral in the order dydzdx then the sum of the six limits of integration =  \(\int\limits^x_0\int\limits^2_1 f(x,y) dydx\)
