URGENT A bakery wanted to make their muffins more uniform in size. They reworked their equipment to do so. To test the changes, they made 25 muffins then measured each one. Which of the following should they use to determine whether or not the equipment changes worked?
Select one:
a.
mean
b.
mode
c.
range
d.
interquartile range
Answers
The bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.
To determine whether the equipment changes made by the bakery have resulted in more uniform-sized muffins, they should use the measure of variability. The most suitable measure, in this case, would be the range.
The range is calculated by finding the difference between the maximum and minimum values in a data set. In this scenario, the bakery made 25 muffins and measured each one. By finding the range of the measurements, they can assess the spread of sizes among the muffins.
Here's how they can use the range to evaluate the effectiveness of the equipment changes:
Collect the measurements of all 25 muffins.
Determine the maximum and minimum measurements.
Calculate the range by subtracting the minimum measurement from the maximum measurement.
If the range of the muffin sizes is smaller compared to the range before the equipment changes, it suggests that the modifications have resulted in more uniform-sized muffins. Conversely, if the range remains similar or larger, it indicates that the changes might not have effectively improved the uniformity of muffin sizes.
Therefore, the bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

In September 2016, the cost of gasoline in Berlin was around 1.21 euros per liter.

1 gallon 3.785 liters
Answers
Using proportions, it is found that the equivalent cost in U.S. dollars per gallon would be of 5.11.
What is a proportion?A proportion is a fraction of total amount, and the measures are related using a rule of three.In September 2016, the cost of gasoline in Berlin was around 1.21 euros per liter. Hence, per gallon, that is, per 3.785 liters, we use a rule of three to find the cost.
1.21 euros - 1 liter
x euros - 3.785 liters
Applying cross multiplication:
\(x = 1.21(3.785) = 4.57985\)
Cost of 4.57986 euros per gallon. Since 1 U.S dollar is equivalent to approximately 0.896 euros, we have that:
1 dollar - 0.896 euros
x dollars - 4.57986 euros
Applying cross multiplication again:
\(0.896x = 4.57986\)
\(x = \frac{4.57986}{0.896}\)
\(x = 5.11\)
The equivalent cost in U.S. dollars per gallon would be of 5.11.

Answers
The correct answer is C. It is the graph of f(x) translated 11 units to the left.
The correct answer is:
C. It is the graph of f(x) translated 11 units to the left.
When we have a function of the form g(x) = f(x - a), it represents a horizontal translation of the graph of f(x) by 'a' units to the right if 'a' is positive and to the left if 'a' is negative.
In this case, g(x) = f(x - 11), which means that the graph of f(x) is being translated 11 units to the right. However, the answer options do not include this specific transformation. The closest option is option C, which states that the graph of g(x) is translated 11 units to the left.
The graph of f(x) = x is a straight line passing through the origin with a slope of 1. If we apply the transformation g(x) = f(x - 11), it means that we are shifting the graph of f(x) 11 units to the right. This results in a new function g(x) that has the same shape and slope as f(x), but is shifted to the right by 11 units.
Therefore, the correct answer is C. It is the graph of f(x) translated 11 units to the left.

A cannonball is fired in the air at an angle of 45°. How far does it travel before it is 600 feet above ground? (Assume the cannonball travels in a straight line. Ignore the force of gravity and wind resistance. Round your answer to the nearest foot.)
Answers
Answer:
Step-by-step explanation:
Since the cannonball is fired at an angle of 45°, it will have the same horizontal and vertical velocities.
Let x be the distance it travels before it is 600 feet above ground. At this point, its vertical displacement will be 600 feet, and we can use the formula for vertical displacement:
y = v0*t + (1/2)at^2
Since there is no initial vertical velocity and we are ignoring gravity, a = 0 and the equation simplifies to:
y = 0*t + 0 = 600
Solving for t, we get:
t = sqrt(2y/a) = sqrt(2*600/0) = undefined
This means that the cannonball will never be 600 feet above ground if we ignore gravity. Since this is not realistic, we cannot answer this question without additional information or by assuming that gravity is acting on the cannonball.

The equation for the line in slope-intercept form that is Perpendicular to the line y = -x +4; containing the point (1, -2) is y = x - 3
The slope intercept equation;The slope intercept equation can be represented as follows:
y = mx + bwhere
m = slope
b = y-intercept
The equation of the line is perpendicular to the line y = -x + 4.
For equations of a line to be perpendicular to each other, the product of their slope is equals to -1.
Therefore,
m₁m₂ = -1 (perpendicular)
-m₂ = -1
m₂ = 1
This means the equation we are looking for has a slope of 1.
Therefore,
