Tom was saving $3000 for a trip. He initially deposited $200 in a savings account and then deposited a fixed amount every month in the account for the next 5 months. Then he received a check in the mail. The check was three times as much as the total amount he had saved so far. When he deposited the check in his savings account, he had $200 more than he needed. What was the fixed amount he deposited in the savings account during the 5 months?
Huey works 175 hours each month and earns $14.25 per hour after taxes. His monthly budget is shown. How much money is left over in his budget for unplanned expenses?
Answer:
Nothing will be left over.
Step-by-step explanation:
You need to multiply the 175 by 14.25 to get his total income each month.
Then you add all of the expenses of 1250, 200, 350, 400, 225, 300.
Huey earns 2,493.75 every month, and his expenses are 2,725.
2,493.75 - 2725 = a negative rational number
I ain't gonna do it, because he ain't got no money in his wallet.
(I don't talk like that above, I'm just pretending to be an official Texan.)
If he has negative money left over, I don't think he would spend some more tbh, so the answer would be nothing would be left over.
Hope this helps someone in the future!

Vicki started jogging. The first time she ran she ran 3/16 mile. The second time, she ran 3/8 Mile, and the third time, she ran 9/16 mile. If she continue this pattern, when was the first time she ran more than one mile explain
Answer:
In seventh time she ran more than one mile from first time she ran.
Step-by-step explanation:
Given Vicki started jogging. The first time she ran she ran 3/16 mile. The second time, she ran 3/8 Mile, and the third time, she ran 9/16 mile.
We have to find when was the first time she ran more than one mile.
The sequence followed is
[tex]\frac{3}{16}, \frac{6}{16}, \frac{9}{16}, \frac{12}{16}, \frac{15}{16}, \frac{18}{16}, \frac{21}{16}....[/tex]
First time she ran more than 1 mile is [tex]\frac{3}{16}+1=\frac{19}{16}[/tex]
In the seventh time she ran [tex]\frac{21}{16}[/tex] miles which is more than one mile from the first time.
Hence, in seventh time she ran more than one mile from first time she ran.

Ron is taking an inventory at his store. Based on previous sales, he predicted sales of 25 folders and 230 erasers. He actually sold 30 folders and 200 erasers. What is the percent error for the erasers?
Answer: There is 15% error for the erasers
Step-by-step explanation:
Since we have given that
Number of folders he predicted = 25
Number of erasers he predicted = 230
Total number of inventories he predicted is given by
[tex]230+25=255[/tex]
Number of erasers he actually sold = 200
Number of folders he actually sold = 30
Total number of inventories he actually sold is given by
[tex]200+30=230[/tex]
Error in estimation is given by
[tex]230-200=30[/tex]
Percentage of error for the erasers only
[tex]\frac{30}{200}\times 100\\\\=\frac{30}{2}\\\\=15\%[/tex]
Hence, there is 15% error for the erasers.
Answer:

The distance between major cracks in a highway follows an exponential distribution with a mean of four miles. (a) what is the standard deviation of the distance between two major cracks
The level of nitrogen oxides (nox) in the exhaust after 50,000 miles or fewer of driving of cars of a particular model varies normally with mean 0.03 g/mi and standard deviation 0.01 g/mi. a company has 64 cars of this model in its fleet. what is the level l such that the probability that the average nox level x for the fleet is greater than l is only 0.01? (hint: this requires a backward normal calculation. round your answer to three decimal places.)
We can use the z-score formula with the known z-score corresponding to a probability of 0.01 to calculate the exhaust NOx emission level. This gives us approximately 0.001 g/mi.
Explanation:In this scenario, we're dealing with a normal distribution problem wherein we use the formula for z-score to answer it. The z-score formula is =(−)/(/√), where x is the data point, μ is the population mean, n is the size of the data set, and σ is the standard deviation.
In this case, we want to find x, or the NOx emission level, such that the probability of finding an automobile with a level greater than x is 0.01. So, we need to find the z-score that corresponds to a probability of 0.01 and then use it in our formula to solve for x.
Using standard z-score tables or an online z-score calculator, we find that a probability of 0.01 corresponds to a z-score of approximately -2.33 (p and z have opposite signs). We then substitute this z-score, along with the given mean μ=0.03 and standard deviation σ=0.01 into the z-score formula, solving for x. The value of n is 64 (number of vehicles in the fleet).
Inserting these values into the formula gives us = + z/√ =0.03 + (-2.33)*(0.01/√64), which simplifies to =0.03 - (2.33/80) = 0.03 - 0.029125= 0.000875 g/mi. Therefore, the NOx emission level, such that the probability of finding an automobile with a level greater than it, is 0.01 for this fleet is approximately 0.001 g/mi when rounded to three decimal places.

To find the level l such that the probability that the average NOx level x for the fleet is greater than l is only 0.01, we can use the z-score formula and the properties of the normal distribution. The z-score formula allows us to convert a probability into a corresponding value on the distribution. Rearranging the z-score formula, we can find the value of l.
Explanation:To find the level l such that the probability that the average NOx level x for the fleet is greater than l is only 0.01, we can use the z-score formula and the properties of the normal distribution. The z-score formula is z = (x - µ) / (σ / √n), where x is the average NOx level, µ is the mean, σ is the standard deviation, and n is the sample size. We want to find the value of l such that the area to the right of l under the normal curve is 0.01.
First, we need to find the z-score corresponding to a right-tail probability of 0.01. This can be done using a z-table or a calculator. In this case, the z-score is approximately 2.326. Now we can use the z-score formula to find the value of l. Rearranging the formula, we have l = µ + (z * σ / √n). Substituting the given values, l = 0.03 + (2.326 * 0.01 / √64). Calculating this, we get l ≈ 0.031.
Therefore, the level l such that the probability that the average NOx level x for the fleet is greater than l is only 0.01 is approximately 0.031 g/mi.

List 3 values that would make this inequality true 43 < y -30
Final answer:
To make the inequality 43 < y - 30 true, add 30 to both sides to get 73 < y. Any number greater than 73, such as 74, 80, or 90, will satisfy the inequality.
Explanation:
To find values that make the inequality 43 < y - 30 true, you simply need to add 30 to both sides of the inequality. This gives you:
73 < y
This means that any value greater than 73 will make the inequality true. Here are three examples:
y = 74 (since 74 is greater than 73)y = 80 (since 80 is greater than 73)y = 90 (since 90 is greater than 73)You can choose any three numbers greater than 73, and they will satisfy the inequality 43 < y - 30.

Express in exponential form. log100.001 = -3
Answer:
I believe you meant to put " log10 (0.001)= -3
10^-3=0.001
The expression log100.001 = -3 in exponential form is 10^-3 = 0.001. This demonstrates that 10 raised to the power of -3 equals 0.001, showing the inverse relationship between logarithms and exponents.
To express log100.001 = -3 in exponential form, recall that the logarithm is the exponent to which the base, in this case, 10, must be raised to produce the given number. The equation log10(0.001) = -3 tells us that the base 10 raised to the power of -3 equals 0.001.
In exponential form, this can be written as 10-3 = 0.001.The concept of converting a decimal to a negative power of 10 involves moving the decimal point to make the number into a whole number, and the negative exponent indicates how many places the decimal point needs to move to the left. In our case, 10-3 means we move the decimal three places to the left: 1 becomes 0.001.

HELP 50 POINTS! What are the key features needed to graph a polynomial function? Explain how to find these key features to sketch a rough graph of a polynomial function.
The explanation can be given down in details . Using this information
are the key features needed to graph a polynomial function and to find these key features to sketch a rough graph of a polynomial function.
To graph a polynomial function, you need to identify and understand its key features, which include:
Degree: The highest power of the variable in the polynomial determines its degree. For example, a polynomial of degree 3 would have terms like [tex]ax^{3} +bx^{2} +cx+d.[/tex] The degree influences the behavior of the polynomial, such as whether its ends point up or down.
Leading Coefficient: The coefficient of the term with the highest power of the variable. It influences the end behavior of the polynomial, determining whether the graph rises to the left and rises to the right or falls to the left and falls to the right.
Roots (Zeros): These are the values of [tex]x[/tex] for which the polynomial evaluates to zero. They are the points where the graph crosses the [tex]x[/tex]-axis.
Turning Points: Points where the graph changes direction. These occur at local maxima or minima and can be found by setting the derivative of the polynomial equal to zero and solving for [tex]x[/tex].
To sketch a rough graph of a polynomial function, follow these steps:
Determine the Degree and Leading Coefficient: Identify the highest power of the variable and the coefficient of that term.
Find the Roots (Zeros): Set the polynomial equal to zero and solve for
[tex]x[/tex]. These are the points where the graph intersects the x-axis.
Identify Turning Points: Find the critical points by taking the derivative of the polynomial, setting it equal to zero, and solving for
[tex]x[/tex]. Then, use the second derivative test or analyze the behavior of the function around these points to determine whether they are local maxima or minima.
Plot Key Points: Use the roots and turning points to plot key points on the graph.
Consider End Behavior: Determine whether the leading coefficient is positive or negative. If it's positive, the ends of the graph will point upwards; if it's negative, they will point downwards.
Sketch the Curve: Connect the plotted points smoothly, taking into account the behavior of the polynomial between the key points. Make sure to show any symmetry if present and adjust the curvature based on the behavior around turning points.
Optional: Use a Graphing Tool: If available, utilize graphing software or calculators to verify your sketch and refine it if necessary.
By following these steps, you can sketch a rough graph of a polynomial function and visualize its key features effectively.
