Answer:
75%
Step-by-step explanation:
We are given that Sara bought a chest for $42, and then sold it for $73.50.
Recall that when finding by how much something was marked up, you should use the following formula:
(new price-original price)/(original price)
Let's substitute the values, like so:
[tex]\frac{73.50-42}{42}=\\\\ \frac{31.50}{42}[/tex]
Now, set up a proportion to find what this fraction is as a percentage:
[tex]\frac{31.5}{42} =\frac{x}{100} =\\42x=3150=\\x=75[/tex]
So, the price was marked up by 75%.
About 16% of people who get their feet examined are found to have athlete's foot. What is the probability of a podiatrist examining five people until he finds the first patient who has athlete's foot? (0. 16)^5 (0. 84)^4(0. 16)^1 (0. 16)^4(0. 84)^1 (0. 84)5 1 − (0. 16)^4
The probability of examining the five people till first patient has athlete's foot is given by (0. 84)^4(0. 16)^1.
Percent of people have athlete foot = 16%
Let us consider the probability of success represented by p = 0.16.
Using geometric distribution,
Probability of finding first patient with athlete's foot on kth examination is given by geometric probability distribution,
P(X = k) = (1 - p)^(k - 1) × p
where X is random variable representing number of trials needed until first success.
Probability of finding the first patient with athlete's foot on the fifth examination k = 5,
⇒ P(X = 5) = (1 - p)^(5 - 1) × p
⇒ P(X = 5) = (0.84)^4 × 0.16
Simplify it we get,
⇒ P(X = 5) = 0.0473
Therefore, the probability of a podiatrist examining five people until he finds the first patient who has athlete's foot is (0. 84)^4(0. 16)^1.

For the given inequality substitute the coordinates of x and y to form the graph of y ≥ 2000 (1 + 0.04)ˣ.
What is compound interest?Interest that is calculated on both the initial principle and any accrued interest is known as compound interest. This implies that the interest for the subsequent period is computed using the new total amount after the interest for the prior month has been added to the principal. If the interest rate and the duration are both high, the interest might add up to a sizable amount over time. Savings accounts, investments, loans, and other financial instruments frequently use compound interest.
For the given inequality we have:
For x = 0, y = 2000.
For x = 1, y = 2000(1 + 0.04) = 2080.

When solving an oblique triangle given three sides, use the inverse cosine form of the Law of cosines to solve for an angle.
When solving an "oblique-triangle" given three sides, we would use the inverse cosine, form of the Law of Cosines to solve for an angle.
The "Inverse-Cosine" function allows us to find the measure of an angle when given the ratio of the lengths of the triangle's sides.
The "Law-of-Cosines" relates the lengths of the sides of a triangle to the cosine of one of its angles.
The "Law-of-Cosines" states that for any triangle with sides of lengths a, b, and c, and opposite angles A, B, and C, respectively:
⇒ c² = a² + b² - 2ab × cos(C),
To solve for an angle, we would rearrange the equation to find the cosine of the angle,
⇒ Cos(C) = (a² + b² - c²)/(2ab),
Then, we will take the inverse cosine of both sides of the equation to find the value of the angle,
⇒ C = cos⁻¹((a² + b² - c²)/(2ab)),
This helps us to find the measure of angle C, depending on the units used in the original triangle sides.

Spinning a spinner that has 5 equal sections marked 1 through 5 and anding on an even number. Find the probability and write answer in simplest form.
The probability of spinning an even number is 2/5, which can be written in simplest form.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
The spinner has 5 equal sections marked 1 through 5. Two of the five numbers are even (2 and 4). Therefore, the probability of spinning an even number is:
Probability of spinning an even number = (number of even numbers) / (total number of possible outcomes)
Probability of spinning an even number = 2/5
Hence, The probability of spinning an even number is 2/5, which can be written in simplest form.

Select the correct answer. Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(-13) = 20 B. g(7) = -1 C. g(0) = 2 D. g(-4) = -11
Therefore, the correct answer is A. We cannot determine whether g(-13) = 20 or not as -13 is outside the domain of g, but it is a possibility within the Domain range of g.
How are the domain and range determined?Determine the values of the independent variable x for which the function is specified in order to find the domain and range of the equation y = f(x). Simply write the equation as x = g(y), and then determine the domain of g(y) to determine the function's range.
Since g has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45, we can eliminate options B and D as they fall outside the range of g.
Since -13 is outside of the range of g, we are unable to verify whether g(-13) = 20 for option A.
For option C, we are given that g(0) = -2, so option C cannot be true.
Therefore, the correct answer is A. We cannot determine whether g(-13) = 20 or not as -13 is outside the domain of g, but it is a possibility within the range of g.

a freight train left a station at 12 noon g . 4. , o~g north at a rate of 50 miles per hour. at 1:00 p.m. a passenger train left the same station, going south at a rate of 60 miles per hour. at what time were the trains 380 miles apart?
The trains will be 380 miles apart at 3:00 PM, which is 4 hours after the freight train leaves the station at 12 noon.
How to solve the problem for distance and time?We can use the formula d = rt (distance = rate x time) to calculate the distance each train has traveled during this time:
Let's call the time elapsed from 12 noon until the trains meet as t hours.
During this time, the freight train has traveled at a rate of 50 mph for t hours and the passenger train has traveled at a rate of 60 mph for (t-1) hours (since it started one hour after the freight train).
Distance traveled by freight train = 50t
Distance traveled by passenger train = 60(t-1)
The total distance between the two trains at time t is the sum of these distances, which we can write as:
Total distance = 50t + 60(t-1)
We want to find the time t at which the total distance is 380 miles. So we can set up the equation:
50t + 60(t-1) = 380
Simplifying this equation, we get:
110t - 60 = 380
110t = 440
t = 4
Therefore, the time elapsed from 12 noon until the trains meet is 4 hours. Since the passenger train left one hour after the freight train, it has been traveling for 3 hours.
So the time at which the trains are 380 miles apart is 3:00 PM (12 noon + 4 hours).

Find the number of red counters and the number of green counters that were in the bag originally
Number of red counters in the original bag is 3, and the number of green counters is 7.
Let's use algebra to solve the problem. Let U be the number of red counters and G be the number of green counters originally in the bag.
From the first part of the problem, we know that
Probability (selecting a green counter) = G / (U + G) = 3/7
Solving for U in terms of G, we get
U = (7G - 3G) / 3 = 4G/3
So we know that there were 4G/3 red counters and G green counters in the bag originally. But since the number of counters must be a whole number, we can assume that there were 4R red counters and 3G green counters originally, where R and G are both integers and R + G is the total number of counters.
After adding 2 red and 3 green counters, the number of counters in the bag is now R + 2 + G + 3 = R + G + 5.
From the second part of the problem, we know that
P(selecting a green counter) = (G + 3) / (R + G + 5) = 6/13
Solving for R in terms of G, we get
R = (13G - 9G - 15) / 7 = 4G/7 - 15/7
Since R must be an integer, we can try different values of G to see if R is an integer. For example, if G = 7, then R = 3 and the total number of counters is 10.

Since the vertex is (0, -3), the quadratic function can be written in vertex form as:
f(x) = a(x - 0)^2 - 3
Where 'a' is a constant that determines the shape of the parabola. Since the end behavior of the function is y --> - Infinite as x --> - infinite and y --> - Infinite as x --> + infinite, the leading coefficient 'a' must be negative.
So, f(x) = -a(x^2 - 0x) - 3
Now, using the given point (1, -7) on the parabola, we can substitute the coordinates into the function and solve for 'a'.
-7 = -a(1^2 - 0(1)) - 3
-7 = -a - 3
a = 10
Therefore, the quadratic function that satisfies the given characteristics is:

If older men are shorter than younger men. However, we do have information about the mean height for U.S. men, which is 69.4 inches.
Additionally, we have a sample of 170 men between the ages of 60 and 69, but we do not have the value for the mean height of this sample (represented as "x" in the question).
If we were given the value of "x", we could compare it to the mean height for all U.S. men and potentially make conclusions about the height of older men compared to younger men.

-16x^2+160x+120 in vertex form
The vertex form of the quadratic expression -16x² +160x+120 is -16(x - 5)² + 520.
What is vertex form?
Vertex form is a way to write a quadratic function in the form:
f(x) = a(x - h)²+ k
where "a" is the vertical stretch or compression factor, "h" and "k" are the x-coordinate and y-coordinate of the vertex of the parabola respectively. The vertex form allows you to easily identify the vertex and the direction of the parabola's opening.
To write -16x²+160x+120 in vertex form, we need to complete the square.
First, let's factor out the coefficient of x²:
-16(x² - 10x) + 120
Next, we need to add and subtract (10/2)² = 25 to the expression inside the parentheses:
-16(x² - 10x + 25 - 25) + 120
Now we can group the first three terms and factor the perfect square trinomial:
-16((x - 5)² - 25) + 120
Simplifying:
-16(x - 5)² + 520
Therefore, the vertex form of the quadratic expression -16x² +160x+120 is -16(x - 5)² + 520.

2. For two consecutive integers, the sum of the smaller and twice the larger is 29. Find the smaller integer.
1. we can use the first equation to find y = 3x + 1 = 3(9) + 1 = 28 So, the larger integer is 28, (2). The smaller integer is 9. The larger integer is 10, which is the next consecutive integer.
What is an integer ?An integer is a whole number ,neither a fraction or a decimal, in mathematics. Integers can be zero, positive, or negative.
Integer examples include -3, -2, -1, 0, 1, 2, 3, and so forth.
The letter "Z" stands for the set of integers.
In mathematics and allied disciplines such as computer science, physics, and finance, integers are utilized extensively.
What is a whole number ?A whole number is a non-negative integer in mathematics, which indicates that it is either a positive integer or zero.
Negative and fractional numbers are not included in whole numbers. The full integers 0, 1, 2, 3, 4, and so on are examples.
In many different branches of mathematics as well as in other disciplines, such as arithmetic, algebra, and geometry, whole numbers are used. They are also employed in daily tasks like quantity calculations and object counts.
According to question :-
Let's call the smaller integer x and the larger integer y. We know that:
y = 3x + 1 (the largest of the two integers is one more than three times the smaller)
x + y = 37 (the sum of the two integers is 37)
We can use substitution to solve for y in terms of x:
x + (3x + 1) = 37
4x + 1 = 37
4x = 36
x = 9
Now we can use the first equation to find y:
y = 3x + 1 = 3(9) + 1 = 28
So the larger integer is 28.
Let's call the smaller integer x and the larger integer y. We know that:
y = x + 1 (the integers are consecutive)
x + 2y = 29 (the sum of the smaller and twice the larger is 29)
We can substitute y = x + 1 in the second equation:
x + 2(x + 1) = 29
Simplifying and solving for x:
3x + 2 = 29
3x = 27
x = 9
So the smaller integer is 9. The larger integer is 10, which is the next consecutive integer.

An investment of $600 is made into an account that earns 6. 5% annual simple interest for 15
years. Assuming no other deposits or withdrawals are made, what will be the balance in the
account?
According to the investment, after 15 years, the balance in the account would be $1185.
To calculate the final balance after 15 years, we can use the formula for simple interest:
Simple Interest = Principal x Interest Rate x Time
In this case, the principal is $600, the interest rate is 6.5%, and the time is 15 years.
Simple Interest = $600 x 0.065 x 15
Simple Interest = $585
So the investment of $600 earns $585 in simple interest over 15 years. To find the final balance, we add the interest earned to the initial investment:
Final Balance = Principal + Simple Interest
Final Balance = $600 + $585
Final Balance = $1185
