A company finds that its advertising costs increased from 72000 to 76680 in a year. What was the rate of increase?
Using the percentage increase formula, we know that the rate of increase in the advertising cost of the company is 93.5%.
What is the percentage?In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.
The percent symbol, "%," is widely used to denote it even if the abbreviations "pct," "pct," and rarely "pc" are also employed.
A% is a number that has neither dimensions nor a defined unit of measurement.
For instance, if you properly answered 75 out of 100 questions on a test, you would have received a 75% grade (75/100).
So, the percentage increase formula:
% increase: original - increase/original * 100
Increase: 76680-72000 - 4680
Now, substitute values as follows:
% increase: original - increase/original * 100
% increase: 72000 - 4680/ 72000* 100
% increase:93.5
Therefore, using the percentage increase formula, we know that the rate of increase in the advertising cost of the company is 93.5%.

Answer:
The correct answer is B. looking for work/total work force.
Unemployment rates are typically calculated by dividing the number of people who are looking for work by the total work force. The work force includes all people who are currently employed or actively looking for work, regardless of whether they are currently employed. The number of people who are looking for work is determined by surveying individuals and asking them whether they are currently seeking employment. The unemployment rate is then calculated by dividing the number of people who are looking for work by the total work force, and expressing this as a percentage.
The other answer choices are not accurate ways of calculating unemployment rates. Dividing the total work force by the number of layoffs (A) would not give an accurate measure of unemployment, as it would not account for people who are looking for work but have not been laid off. Dividing the number of people looking for work by the total population (C) would also not be an accurate way of calculating unemployment, as it would not take into account people who are not part of the work force (e.g. children, retirees, etc.). Therefore, the correct method for calculating unemployment rates is to divide the number of people looking for work by the total work force.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The unemployment rate for any area is the number of area residents without a job and looking for work divided by the total number of area residents in the labor force.
Suppose that P(E) = 0.85, P(F) = 0.40, and P(E and F) = 0.30.
Calculate P(F|E).
By using the concept of probability, it can be calculated that-
P(F|E) = [tex]\frac{P(F \ and \ E)}{P(E)} = \frac{6}{17}[/tex]
What is probability?
Probability gives us the information about how likely an event is going to occur
Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probability of any event is greater than or equal to zero and less than or equal to 1.
Probability of sure event is 1 and probability of unsure event is 0.
Here P(F|E) means probability of happening of event F knowing event E will happen
P(E) = 0.85, P(F) = 0.40, and P(E and F) = 0.30.
P(F|E) = [tex]\frac{P(F \ and \ E)}{P(E)} = \frac{0.30}{0.85} = \frac{6}{17}[/tex]

A solid dressing recipe includes 4/5 cup of lime juice for every 2 cups of Greek yogurt. How many cups of lime juice does Marquez need for 3 cups of Greek yogurt?
Answer:
1 1/5
Step-by-step explanation:
So first we need to realize that 4/5 can be turned into 8/10. Plus since they need 3 cups, not 2 (which we have been provided with the cups for) then we have to split it in half. So it would be 8/10 + 4/10. Which is 12/10 or 1 2/10 or 1 1/5

12. How could you write a system of inequalities using the quadratic functions in
the graph so that (6, 6) is a solution to the system but (6, -6) is not a solution to
the system.
Answer:
To write a system of inequalities that has the point (6, 6) as a solution but not (6, -6), we can use the fact that the point (6, 6) is above the graph of the quadratic function, but the point (6, -6) is below the graph. Therefore, we can write a system of inequalities that includes the condition that the y-value must be greater than the value of the quadratic function at a given x-value.
For example, we could use the quadratic function y = x^2 and write the following system of inequalities:
y > x^2
y > 6
The first inequality states that the y-value must be greater than the value of the quadratic function at a given x-value. The second inequality is added to ensure that the y-value is greater than 6, which is necessary for the point (6, 6) to be a solution.
Since the point (6, 6) satisfies both of these inequalities, it is a solution to the system. However, the point (6, -6) does not satisfy the first inequality, since the y-value is less than the value of the quadratic function at x = 6. Therefore, it is not a solution to the system.
Overall, the system of inequalities would be as follows:
y > x^2
y > 6
Cadence has a collection of 52 dolls that all have either blue-eyes or green-eyes. Cadence has 16 more blue-eyed dolls than green-eyed dolls. How many green-eyed dolls does Cadence have? How many blue-eyed dolls?
Answer:
18 green eyed dolls and 34 blue eyed dolls
Step-by-step explanation:
Cadence has a total of 52 dolls, either green eyed or blue eyed so lets take the number of green eyed dolls as g and the number of blue eyed dolls as b. So you have
b + g = 52
also we know b is 16 greater than g so
b - 16 = g
transpose 16 & g
b - g = 16
Now we add the equations
b+g = 52
b-g = 16
______
2b = 68
(+g and -g cancel each other out)
so b = 34
If we put 34 into an earlier equation
34 + g = 52
g = 52 - 34
g= 18
Fatima conducts emissions inspections on cars. She finds that 6\%6%6, percent of the cars fail the inspection. Let ccc be the number of cars fatima inspects until a car fails an inspection. Assume that the results of each inspection are independent.
The probability that the first failed inspection occurs on Fatima's 5th inspection i.e P(c = 5) is 0.05..
Geometric probability distribution:In probability and statistics,the geometric distribution defines the probability of the first success occurring after k trials. The probability of success is p
P r ( X = k ) = ( 1 − p )⁽ᵏ⁻¹⁾ p.
We have given that,

Probability that car fail the inspection, p = 6% = 0.06
let c denoted the number of cars that are inspected until one car fail to inspection.
The random variable c here. Here c follow geometric probability distribution with probability of success (0.06).
Plugging all known values in above formula we get, p(c= 5) = (1-0.06)⁴ × 0.06

What does a scale look like in math?The ratio that describes the relationship between the true figure itself and model is called the scale. It serves as a representation of the real statistics in smaller units on maps. A scale of 1:5, for instance, indicates that 1 on the map is approximately the size of 5 in the actual world.

Horse height in drawing equals one inch
The height of the horse = 250 inche
The original height of the horse = 15 inche
The height in the picture = x inches
To find the height the horse in the picture, we have to use proportion
1 inch : 250 inche = x inches : 15 inche
1 / 250 = x / 15

How do you graph a rational function example?
To graph a rational function example, start by writing the equation in the form y = (ax + b)/(cx + d).
Then, plot the points where the denominator equals zero (when x = -d/c). These points are called vertical asymptotes.Next, plot the points where the numerator equals zero (when x = -b/a). These are called horizontal asymptotes.Finally, plot points between the vertical and horizontal asymptotes to graph the rational function.Plotting the points between the vertical and horizontal asymptotes will allow you to see the shape of the graph. Start by plotting points on either side of the vertical and horizontal asymptotes. Then, plot points at evenly spaced x-values between the vertical and horizontal asymptotes. For example, if the vertical asymptote is at x=-d/c, and the horizontal asymptote is at x=-b/a, you can plot points at x=-1.5d/c, x=-0.5d/c, x=-1.5b/a, and x=-0.5b/a. By plotting these points and connecting them with a smooth curve, you can graph the rational function.
