The concession stand charges $2.25 for each nacho.
What is the percentage?
In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" is also used. A percentage is a dimensionless number; it has no unit of measurement.
To find out how much the concession stands charge for each nacho, we need to calculate the markup percentage.
The markup percentage is calculated by:
(Markup Amount / Cost) * 100 = Markup Percentage
In this case, the markup amount is 80% of the cost of each nacho, which is:
(80/100) * $1.25 = $1
So, the markup amount is $1.
To calculate the final price of each nacho, we need to add the markup amount to the cost:
$1.25 (cost of nacho) + $1 (markup amount) = $2.25
Therefore, the concession stand charges $2.25 for each nacho.

The Salk vaccine field trials were conducted only in certain experimental areas (school districts), selected by the Public Health Service in consultation with local officials. In these areas, there were about 3 million children in grades 1, 2, or 3; and there were about 11 million children in those grades in the United States . In the experimental areas, the incidence of polio was about 25% higher than in the rest of the country. Did the Salk vaccine filed trials cause children to get polio instead of preventing it? Answer yes or no, and explain briefly.
Based on the information provided, it can be concluded that the vaccine trials most likely did not cause children to get polio as these are independent variables.
What is causality bias?This type of bias implies people believe two events are related as a cause or effect. This often happens when one event follows another, and therefore people believe one event causes the other.
In this case, people are likely to believe the vaccine caused higher polio rates just because after the vaccine, polio rates seemed to increase. However, these two variables are independent as vaccines produce immunization against polio.

A bottle of liquid laundry detergent priced at $16.99 for a 52-load bottle has been changed to $16.49 for a 48-load bottle. By what percentage has the price per load changed?
Answer:
5.1% increase
Step-by-step explanation:
You want the percentage change in price per load when the price of detergent went from $16.99 for 52 loads to $16.49 for 48 loads.
Percentage changeThe percentage change is given by the formula ...
((new price)/(old price) -1) × 100%
Price per loadThe price per load is found by dividing the price of the bottle of detergent by the number of loads it will wash.
old price per load = $16.99/52 ≈ $0.32673
new price per load = $16.49/48 ≈ $0.34354
ApplicationThen the percentage change is ...
(0.34354/0.32673 -1) × 100% ≈ 0.05145 × 100% ≈ 5.1%
The price per load has increased by about 5.1%.

Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
Right triangle ABC.
∠C = 90
The other two sides are a = 8 and b = 8
This means,
The angle opposite to the side a = 8 and b = 8 are equal.
Now,
∠A = ∠C
∠C + ∠A + ∠B = 180
90 + ∠A + ∠B = 180
2∠A = 180 - 90
∠A = 90/2
∠A = 45
∠B = 45
Now,
c² = a² + b²
c² = 64 + 64
c² = 128
c = √128
c = 11.31
Thus,
Sin A = a/c = 8/11.31 = 0.71
Cos A = b/c = 8/11.31 = 0.71

3. Ato Liku purchases a house for Br. 250, 000. He makes a 20% down payment, with a balance amortized by a 30 year mortgage at an annual interest rate of 12% compounded monthly. a) Determine the amount of the monthly mortgage payment. b) What is the total amount of interest Ato Liku will pay over the life of the mortgage? c) Determine the amount of the mortgage Ato Liku will have paid after 10 years?
Answer:
a) To determine the monthly mortgage payment, we first need to calculate the amount of the loan, which is equal to the purchase price of the house minus the down payment. In this case, the loan amount is 250,000 * 0.8 = 200,000. Next, we need to calculate the monthly interest rate, which is equal to the annual interest rate divided by 12. In this case, the monthly interest rate is 0.12/12 = 0.01. Using the formula for the monthly mortgage payment (P = L[i(1+i)^n]/[(1+i)^n-1]), where P is the monthly payment, L is the loan amount, i is the monthly interest rate, and n is the number of payments (in this case, 30 years * 12 = 360), we can calculate the monthly payment as:
P = 200,000[0.01(1+0.01)^360]/[(1+0.01)^360-1] = 1326.91
b) To calculate the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount from the total amount of payments made over the life of the mortgage. In this case, that would be 360 * 1326.91 - 200,000 = 480,596.
c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we can multiply the monthly mortgage payment by the number of payments made in 10 years (10 years * 12 = 120). In this case, that would be 120 * 1326.91 = 159,223.20.

What is a pentagon?A pentagon is a 2D polygon with five sides and five angles.
Pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°.
We are given in the figure , following information about a pentagon:
3 angles are 90 degrees, one angle is (6x+1) degrees, and the other angle is (8x-11) degrees.
To solve for x, we need to add all of the angles together.
The sum of the angles in any polygon is always equal to (n-2)*180, where n is the number of sides in the polygon.
In this case, n=5, so the sum of the angles is (5-2)*180 = 540 degrees.
We can now solve for x by substituting our known values into the equation.

based on the graph of the general solution to the differential equation dy over dx equals 2 times x plus y comma which of the following statements is true?
Based on the graph of the general solution to the differential equation dy/dx = 2x + y, the option C: The slopes are all positive in Quadrant 1, is true.
What is a differential equation?
A differential equation is an equation that contains at least one derivative of an unknown function, either a normal differential equation or a partial differential equation.
The given the differential equation is dy/dx=2x+y.
The graph for the function is drawn.
dy/dx=2x+y
Now slope=2x+y
Along x-axis, y=0.
So, slope=2x≠0.
Since it depends upon x hence the slope along the y-axis are not horizontal.
Along y-axis, x=0.
So, slope=y≠0.
Since it depends upon y the slope along the x-axis are also not horizontal.
In quadrant I -
x,y≥0
So, dy/dx≥0
Hence the slopes are all positive in quadrant I.
In quadrant IV -
x≥0,y≤0
So, dy/dx is not always positive.
Therefore, the slopes are not all positive in quadrant IV.

A group of researchers establish a p-value of 0.05 for their hypothesis test. What does this mean?
a. The probability of getting a significant result for the test is 5%.
b. There is 5% probability that a true null hypothesis will be rejected.
C. The chi-square critical value for their dataset is 0.05
d. Only measured values of 0.05 or greater will be included in the test.
Answer:
b
Step-by-step explanation:
b. There is 5% probability that a true null hypothesis will be rejected.
A p-value of 0.05 represents the probability of obtaining a test statistic as extreme or more extreme than the one observed under the assumption that the null hypothesis is true. In other words, it is the probability of observing the data or more extreme data assuming the null hypothesis is true. It is also the threshold level of significance beyond which the null hypothesis is rejected in favor of the alternative hypothesis. A p-value of 0.05 means that there is a 5% probability that the observed results occurred by chance under the null hypothesis and that there is a 95% probability that the observed results occurred due to a real effect.

Put the decimal point to the right to make the divisor a full number if it isn't already. The dividend's decimal point should likewise be moved the same number of spaces to the right (adding some extra zeros if necessary.)
What is meant by decimal point?To distinguish between a full number and its fractional component, a decimal point is a point or a dot. A different name for it is Decimal Mark. The decimal point is the dot that appears in the middle of a whole number and its fractional component. Decimal numbers include, for instance, 34.5. 5 is the fractional portion in this situation, and 34 is a whole number. The decimal point is ".."The word decimal derives from the Latin decimus, which means tenth, from the base word decem, or 10.

use substitution to solve the system of equations -1=2x-y 8x-4y=-4
Given System of equation has multiple solution.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given a system of equation:
-1 = 2x - y and 8x - 4y = -4
From equation 1
-1 = 2x - y
y = 2x + 1
Substitute this value on equation 2
8x - 4y = -4
8x - 4(2x + 1) = -4
-4 = -4
An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.
