Mark needs a total amount of 215 to buy sneakers and we know that his aunt gave him 100 for the same, he also know that he can earn 16 for each hour that he works at his aunt's store, therefore he needs to work 8 hours.

Mark needs a total amount of 215 to buy sneakers and we know that his aunt gave him 100 for the same,

therefore, we can say that 215 - 100 = 115

therefore, Mark now needs only 115 for him to buy sneakers and  now we need to find how many full hours do Mark need to work to buy sneakers:

therefore, we need to divide 115 by 16 to find out the hours he needs to work at his aunt's store:

115/16 = 7.2

we get 7.2 which also means 7 hours 20 mins but we need to find full hours Mark needs to work, that will be:

8 hours.

Therefore, we know that Mark needs to work 8 full hours for him to buy sneakers.

Answer:

a = 72° b = 88°

Step-by-step explanation:

We know in the cyclic quadrilateral opposite angles are supplementary so

a + 108° = 180° { being opposite angles of cyclic quadrilateral }

a = 180° - 108°

a = 72°

b + 92° = 180° { being opposite angles of cyclic quadrilateral }

b = 180° - 92°

b = 88°

The circumference of the circular test track is 3.3 km. When a car travels around the track from the southernmost point to the northernmost point, it covers the entire circumference of the track.

To calculate the distance traveled by the car, we can use the formula: distance = circumference.

In this case, the distance traveled by the car is equal to the circumference of the track, which is 3.3 km.

So, when the car completes one full lap around the track, it will have traveled a distance of 3.3 km.

If the car completes multiple laps around the track, the total distance traveled will depend on the number of laps. For example:

- If the car completes 2 laps, the total distance traveled will be 2 times the circumference, which is 2 * 3.3 km = 6.6 km.
- If the car completes 3 laps, the total distance traveled will be 3 times the circumference, which is 3 * 3.3 km = 9.9 km.

Therefore, the distance traveled by the car around the circular test track depends on the number of laps completed.

Answer:

6566

Step-by-step explanation:

To find the value of z sub x (dz/dx) for the given implicit function xyz³ + x²y³z = x+y+z, we need to differentiate the equation implicitly with respect to x. This involves taking the partial derivative of each term in the equation with respect to x while treating y and z as independent variables. After calculating the derivative, we can substitute the values of x, y, and z to find z sub x.

To find the derivative fz at the point P(1, 0, -3) for the function Z-X f(x, y, z) = z+y, we can differentiate the function with respect to z. Since the function only depends on z and y, the derivative with respect to z will be 1. Therefore, fz at the point P is equal to 1.

To find zx for the given implicit function xyz³ + x²y³z = x+y+z, we differentiate the equation implicitly with respect to x. Treating y and z as independent variables, we calculate the partial derivative of each term with respect to x.

Taking the derivative of the first term, we have (3xyz² + 2xy³z) dx/dx. Since dx/dx is equal to 1, this term simplifies to 3xyz² + 2xy³z.

The second term, x²y³z, has a partial derivative of (2xy³z) dx/dx, which simplifies to 2xy³z.

The derivative of the right-hand side, x + y + z, with respect to x is simply 1.

Setting up the equation, we have 3xyz² + 2xy³z + 2xy³z = 1.

Simplifying further, we get 3xyz² + 4xy³z = 1.

Substituting the values of x, y, and z at the point P(1, 0, -3), we can calculate the value of zx.

To find fz at the point P(1, 0, -3) for the function Z-X f(x, y, z) = z+y, we differentiate the function with respect to z.

Since the function only depends on z and y, the derivative with respect to z is simply 1.

Therefore, fz at the point P is equal to 1.

Answer:

B) y = -5x + 7

Step-by-step explanation:

Pick 2 points on the line:  (10, 5) and (15, 4)

slope = change in y ÷ change in x = (15 - 10) ÷ (4 - 5) = -5

from inspection, the y-intercept is (0, 7)

Therefore, using slope-intercept formula:  y = mx + b

(where m is the slope and b is the y-intercept)

y = -5x + 7

Step-by-step explanation:

Example: (5,2)

On a graph, the 5 goes on the x-axis and the 2 goes on the y-axis.

Also, in the world of variables, and the alphabet, x is before y.

The 10%-90% rise time of the response is approximately 0.3 seconds, to the nearest third decimal place.

To determine the 10%-90% rise time of a response, we need to find the time it takes for the response to go from 10% of its steady-state value to 90% of its steady-state value.

Looking at the graph or response data provided, we can estimate that the steady-state value of the response is approximately 1.4.

10% of 1.4 is 0.14, and 90% of 1.4 is 1.26.

So we need to find the time it takes for the response to go from 0.14 to 1.26.

By examining the graph or data, we can see that this occurs between t = 0.9 seconds and t = 1.2 seconds.

The difference between these two times is:

1.2 - 0.9 = 0.3 seconds

Therefore, the 10%-90% rise time of the response is approximately 0.3 seconds, to the nearest third decimal place.

Answer:

1. 38.3 x 10^5

2. 6.67 x 10^9

3. 4.48 x 10^4

Step-by-step explanation:

4.2 X 10 ^6 - 1.2 X 10^5 - 2.5 x 10^5

For the above question, we need to make the exponents equal

=> 42 x 10^5  -  1.2 x 10^5  -  2.5 x  10^5

SInce, all the exponents are equal, we can now add and subtract the normally.

=> (42 - 1.2 -2.5) x 10^5

=> (42 - 3.7) x 10^5

=> 38.3 x  10^5

So, the answer to the 1st question is 38.3 x 10^5

Next question:

=> 3.3 x 10^9 + 2.6 x 10^9 +7.7 x 10^8

=>  we need to make the exponents equal

=> 3.3 x 10^9 + 2.6 x 10^9 + .77 x 10^9

=> All the exponents are equal, we can now add and subtract the normally.

=> (3.3 + 2.6 + .77) x 10^9

=> 6.67 x 10^9

=> So the answer to the 2nd question is 6.67 x 10^9

Next question,

=> 8 X 10^4 - 3.4 x 10^4  - 1.2 x 10^3

=> we need to make the exponents equal

=> 8 x 10^4 - 3.4 x 10^4 - .12 x 10^4

=> All the exponents are equal, we can now add and subtract the normally.

=> (8 - 3.4 - .12) x 10^4

=> 4.48 x 10^4

=> So the answer to the 3rd question is 4.48 x 10^4

The solutions to the expressions are:

\(4.2 \times 10^6 - 1.2 \times 10^5 - 2.5 \times 10^5\)=\(38.3\times 10^5\)

\(3.3 \times 10^9 + 2.6 \times 10^9 + 7.7 \times 10^8\) = \(6.67\times 10^9\)

We are 90% confident that the true difference in proportions between France and the United States falls between -0.1783 and 0.1383.

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

The point estimate for the difference in proportions between France and the United States is:

p₁ - p₂ = (60/120) - (26/50) = 0.5 - 0.52 = -0.02

We can use the following formula to calculate the standard error of the difference in proportions:

SE = √(p₁ * (1 - p₁) / n₁ + p₂ * (1 - p₂) / n₂)

where n₁ and n₂ are the sample sizes.

SE = √((0.5 * 0.5 / 120) + (0.52 * 0.48 / 50))

SE = 0.0936

To construct a 90% confidence interval, we can use the formula:

(point estimate) ± (critical value) * (standard error)

The critical value for a two-sided 90% confidence interval with 169 degrees of freedom (calculated as df = (p₁ * n₁ + p₂ * n₂) / (p₁ + p₂)) can be found using a t-distribution table or calculator.

For a 90% confidence level, the critical value is approximately 1.656.

Using these values, the 90% confidence interval for the difference in proportions is:

-0.02 ± 1.656 * 0.0936

which simplifies to:

-0.1783 to 0.1383

Therefore, we are 90% confident that the true difference in proportions between France and the United States falls between -0.1783 and 0.1383.

Part 1a. The correct answer is D, all of the information is required to solve the problem. To compute the bill after tax and tip, we require all the given information.

Here's how you can calculate the bill after tax and tip: Let x be the cost of the meal.

The tax on the meal is 5%, so the tax amount would be 0.05x. Thus, the total cost of the meal is x + 0.05x

= 1.05x.The customer left a 20% tip on the cost of the meal, including tax. So, the tip amount was 0.20 * 1.05x

= 0.21x.The total bill including tax and tip is therefore: x + 0.05x + 0.21x

= 1.26x. Now, substituting the value of the tip left by the customer in the question we get:$1.80

= 0.21x

=> x

= $8.57The total bill including tax and tip is: 1.05 * $8.57 + 0.21 * $8.57

The result of -6 x 4 is -24.

To understand why this is the case, it's important to remember the basic rules of multiplication. When we multiply two numbers together, we are essentially adding one number a certain number of times. For example, 3 x 4 can be thought of as adding 4 three times: 4 + 4 + 4 = 12

In this case, we are multiplying -6 and 4 together. So we are taking -6 and adding it to itself four times: -6 + -6 + -6 + -6 = -24.

It's important to note that the order of the numbers being multiplied does not change the result. So -6 x 4 is the same as 4 x -6, which would also equal -24.

It's also important to remember that when one of the numbers being multiplied is negative, the result will also be negative. So, -6 x 4 = -24

Standard Deviation (σ) = 1.2 oz

Threshold value (X) = 32 oz

We can use the standard normal distribution (Z-distribution) to calculate the cumulative probability.

First, let's standardize the threshold value using the formula

Z = (X - μ) / σ

Z = (32 - 32.3) / 1.2 Z ≈ -0.25

Next, we'll look up the cumulative probability corresponding to Z = -0.25 in the standard normal distribution table or use a calculator.

From the standard normal distribution table or calculator, we find that the cumulative probability for

Z = -0.25 is approximately 0.4013.
