1104.

4800/100=48               48=1%                  48(1%)*23=1104

If a profit of 23% was made on an article bought for 4800 Naira, then the selling price was 5904.

We know that,

Profit%=(selling price- cost price)/cost price.

Now here given, Profit % = 23%.

The cost price = 4800.

Suppose the selling price is, x.

∴We can say,

23=\(\frac{x-4800}{4800}\)×100.

⇒\(x\)-4800 = 23×48.

⇒\(x\)=1104+4800.

⇒\(x\)=5904.

Hence, the selling price was 5904.

The solutions to the quadratic equation f(x) = x² + 10x - 1 are x = -5 + √26 and x = -5 - √26

To solve the quadratic equation f(x) = x² + 10x - 1

we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

For the given equation, a = 1, b = 10, and c = -1.

Substituting these values into the quadratic formula:

x = (-(10) ± √((10)² - 4(1)(-1))) / (2(1))

= (-10 ± √(100 + 4)) / 2

= (-10 ± √104) / 2

Simplifying further:

x = (-10 ± 2√26) / 2

= -5 ± √26

Therefore, the solutions to the quadratic equation f(x) = x² + 10x - 1 are:

x = -5 + √26 and x = -5 - √26

Answer:

  25.1 square inches

Step-by-step explanation:

You want the area of a 1/8 slice of a 16-inch pizza.

The area of a circle is given by the formula ...

  A = πr²

where r represents the radius of the circle, half the diameter.

For the 16-inch diameter pizza, the radius is 8 inches, so the area of the whole pizza is ...

  A = π(8 in)² = 64π in²

The area of a slice will be 1/8 of this:

  slice area = 1/8(64π in²) = 8π in² ≈ 25.133 in²

The area of a slice of the pizza is about 25.1 square inches.

The composition of functions f(g(x)) simplifies to x. This means that for any value of x, the result of the composition is simply x itself.

To solve the composition of functions f(g(x)), where f(x) = 4x and g(x) = x/4, we need to substitute g(x) into f(x) and simplify. Here are the steps to solve it:

Start with the function f(x) = 4x and the function g(x) = x/4.

Substitute g(x) into f(x), replacing every occurrence of x in f(x) with g(x):

f(g(x)) = 4 * (x/4).

Simplifying the expression:

f(g(x)) = x.

The result is f(g(x)) = x, indicating that the composition of functions f(g(x)) is equal to the input function x.

Note: In this case, the composition of functions simplifies to the identity function. The composition of functions involves substituting one function into another and simplifying the resulting expression. Here, when we substitute g(x) into f(x), we find that f(g(x)) simplifies to x, which means that the composition of functions is equivalent to the input function itself.

The one-way ANOVA test would be the best choice to compare the average number of adjustments made by service representatives at five different locations in Texas.

To compare the average number of adjustments made by service representatives at five different locations in Texas, the best choice of statistical test would be the one-way ANOVA (Analysis of Variance) test.

The one-way ANOVA test is used to compare the means of three or more independent groups to determine whether there is a statistically significant difference between them.

Five different groups (locations) that we want to compare.

The one-way ANOVA test allows us to test the null hypothesis that all the groups have the same population mean, against the alternative hypothesis that at least one group has a different population mean than the others.

If the p-value is less than the significance level (usually set at 0.05), we can reject the null hypothesis and conclude that there is a statistically significant difference between the means of the groups.

The one-way ANOVA test, we can determine whether there is a significant difference in the average number of adjustments made by service representatives across the five different locations in Texas.

If a significant difference is found, we can then conduct post-hoc tests to determine which specific locations have different means.

Answer:

Step-by-step explanation:

The clinic should hire at least 7 doctors in order to serve 122 patients per day.

To determine how many doctors the clinic should hire in order to serve 122 patients per day, we need to calculate the number of patients each doctor can see within their working hours.

Let's start by calculating the total number of minutes each doctor works per day. Since each doctor works 8 hours per day and there are 60 minutes in an hour, the total minutes worked by a doctor per day would be 8 hours × 60 minutes = 480 minutes.

Next, we need to find out how many patients a doctor can see within their working hours. Given that each patient requires an average of 27 minutes with a doctor, the number of patients a doctor can see per day would be 480 minutes ÷ 27 minutes per patient = 17.7778 patients.

Since we can't have a fractional number of patients, we need to round this number up to the nearest whole number to ensure that each patient gets the required attention. Therefore, each doctor can see approximately 18 patients per day.

To serve 122 patients per day, we divide the total number of patients by the number of patients each doctor can see per day: 122 patients ÷ 18 patients per doctor = 6.7778 doctors.

Again, we can't have a fractional number of doctors, so we need to round this number up to the nearest whole number. Therefore, the clinic should hire at least 7 doctors to serve 122 patients per day.

In summary, the clinic should hire at least 7 doctors in order to serve 122 patients per day.

HP's pricing strategy allows them to capture a larger customer base, create customer loyalty and long-term profitability.

HP uses the 'razor' and 'blade' model. Here, Laser printer is sold at a lower price while the consumables (printer cartridges) are sold at higher profit margins. This strategy aims to create a recurring revenue stream from the sales of consumables, which have higher profit margins compared to the initial printer sale.

By relying on the sales of consumables, HP diversifies its revenue streams. While printer sales may have lower profit margins, the higher profit margins from consumables help offset those costs and contribute to overall profitability. This reduces HP's reliance on a single revenue source and improves financial stability.

Therefore , HP is leaning towards a scheme which aims at long-term profitability.

The plant that produced the most tomatoes was treated with the old fertilizer, thus it was better. So statement B is correct.

A line plot is one type of graph that helps us to represent the data along the number line. This plot is also referred to as a dot plot. In this plot, we show the data as a check or point above a number line. Each point or check in this plot represents the frequency of each value.

The given plot about fertilizers is a line plot. In this plot, 1 dot over 2 in the old fertilizer treatment means about 2 plants have one tomato.

By comparing the line plot for both the new fertilizer and old fertilizer, we will be able to say that there are more tomatoes produced when the old fertilizer is used than the new fertilizer.

Nearly 65 tomatoes were produced when old fertilizer is used but only 58 tomatoes were produced when new fertilizer is used. Therefore, statement B is correct.

Disjoint events are events that cannot happen at the same time. Two events A and B are independent if the occurrence of A does not affect the probability of B happening, and vice versa. Mathematically, this can be written as P(A and B) = P(A)P(B).

In the case of disjoint events, P(A and B) = 0 because they cannot occur at the same time. Therefore, the condition for A and B to be independent is that either P(A) = 0 or P(B) = 0, since any non-zero probability for either event would make the product P(A)P(B) also non-zero.

Two disjoint events are independent if and only if at least one of them has zero probability.

|x/3| = (-x/3)  if x < 0

Here we want to simplify the absolute value expression:

|x/3|  when we have the restriction x < 0.

First, remember how this function works, we will have:

|x| = x   if x ≥ 0

|x| = -x  if x < 0.

In this case, when x < 0, x/3 < 0.

Then we need to use the second part for that rule, so we can rewrite the expression:

|x/3| = -(x/3)   if x < 0.

Step-by-step explanation:

The measure of angle L is approximately 48.59 degrees.

What is Pythagoras' Theorem?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

We can use trigonometry to solve for angle L. Using the Pythagorean theorem, we can find that the length of side MN is:

MN = sqrt(LN² - LM²) = √(60² - 18²) = √(3444) ≈ 58.66 inches

Now, using the definition of sine, we have:

sin(L) = MN / LN = 58.66 / 60

Taking the inverse sine (sin⁻¹) of both sides, we get:

L = sin⁻¹(58.66/60) ≈ 48.59 degrees

Therefore, the measure of angle L is approximately 48.59 degrees.
