Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

Answer:Woburn, MA – May 18, 2021 — Today Kaspersky announces that Kaspersky Machine Learning for Anomaly Detection (MLAD), designed to reveal deviations in production processes at the earliest stage, is now generally available as a commercial product. The detector is empowered with ML algorithms that analyze telemetry from machinery sensors. It warns of machine malfunctions by raising alerts as soon as manufacturing process parameters (tags) begin to behave in an unexpected way. Kaspersky MLAD provides a feature-rich graphical interface for detailed analysis of anomalies as well as tools that can integrate the product with existing systems to deliver alerts to operators’ dashboards.
In industrial settings, it is critical to keep technological processes on an optimal path and avoid interruptions such as equipment malfunctions, operator errors, or cyberattacks on industrial control systems. If something goes wrong, early detection can prevent disruption and therefore reduce the cost of downtime, the waste of raw materials and the impact of other serious consequences. According to Kaspersky estimates, a 50% reduction in downtime enables annual savings of up to $1 million for a large power plant or $2.5 million for an oil refinery[1].
Kaspersky Machine Learning for Anomaly Detection’s neural network analyzes telemetry in real-time from various sensors used in the production process. It detects minor deviations such as a change in signals’ dynamics or correlations, and gives alerts before the values reach their thresholds and impact performance allowing plant operators to take preventive actions. To be able to detect anomalies, the neural network learns the normal behavior of the machine from historical telemetry data. If a parameter of the production process changes (for example, a new type of raw material is introduced) or a part of the machine is replaced, an operator can re-run the ML trainer to update the neural network. In addition to an ML-based detector, customized diagnostic rules for specific cases can be added at the customer’s request.

In the diagram, △ABC∼△DEF. The area of △ABC is 180 square centimeters. Find the area of △DEF.
pls pls pls help me answer
Answers
Answer:
20
Step-by-step explanation:
The first step is to find out the similarity reason of the sides of the triangle, so we just divide the big side by the small side (12/4=3).
Now, for the similarity reason of the areas, we just square that number (3^2=9).
Then we just divide the area of the big triangle by 9, which is 180/9= 20.
Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. The area of the △DEF is 20cm².
What are Similar Figures?Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. It is denoted by the symbol "~".
Given △ABC∼△DEF, therefore, the sides will be in a particular ratio,
Ratio = AB/DE = 12/4 = 3
Also, the area of △ABC is 180 square centimeters. since the area is a two-dimensional quantity it will be the product of two sides, therefore, the ratio will also be multiplied twice. Thus, the area of △DEF will be 1/9 of the area of △ABC. Hence, the area of △DEF is,
△DEF = △ABC/9
△DEF = 180cm²/9 = 20cm²
Hence, the area of the △DEF is 20cm².

11. From clue 11, we know that John is not a banker or a programmer. Therefore, John is the writer.
12. From clue 12, we know that the writer earns more than the programmer. Therefore, John earns $48,100 and Alyssa earns $44,700.
Therefore:
- Madison is the banker and earns $53,600.
- Alyssa is the programmer and earns $44,700.
- Christopher is the writer and earns $53,600.
- John is the chemist and earns $48,100.

What is the median for the set of data?
71
70
72
74
Answers
Answer:
Step-by-step explanation:
To find the median, we need to arrange the data in ascending order:
70, 71, 72, 74
Since the data set has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 71 and 72. Therefore, the median is:
(71 + 72) / 2 = 143 / 2 = 71.5
So, the median for the given set of data is 71.5.
the width of the rectangle fence is 5 ft less then the length if the length is decreased by 3 ft and the width is increased by 1 ft the area limited by the old fence will be the same as the area of the original fence
Answers
Answer: Length is 6 ft and
Width is 1 ft
Step-by-step explanation: The first clue we have been given is that the width of the rectangular fence is five feet less than it's length. So, if the length is L, the width is L - 5. From that bit of information on we can calculate the area if he rectangular fence as
Area = L x W
Area = L x (L - 5)
Area = L² - 5L
Also, the question further states that if the length is decreased by three feet (L = L - 3), and the width is increased by one foot (W = {L - 5} + 1 and that becomes L - 4), the area of the new enclosure would be the same as the first one. The area of the new enclosure would be given as
Area = L x W
Area = (L - 3) (L - 4)
Area = L² - 4L - 3L + 12
Area = L² - 7L + 12
Since the question states that the area of the original fence and the new one are the same, we can now write the following expression
L² - 5L = L² - 7L + 12
(That is, area of the first set of dimensions equals area of the second set of dimensions)
L² - 5L = L² - 7L + 12
By collecting like terms we now have
L² - L² - 5L + 7L = 12
(Note that when a positive value crosses the equation to the other side, it becomes negative and vice versa)
2L = 12
Divide both sides of the equation by 2
L = 6
Having calculated the length of the rectangular fence as 6 ft, the width is now derived as
W = L - 5
W = 6 - 5
W= 1
Therefore, the length is 6 ft and the width is 1 ft.

Sarah was asked to solve the following problem. Identify her errors and explain how to correct her mistakes.
Answers
Answer:
\(5x^3-18x^2+2x+21\)
Step-by-step explanation:
In the second step, -9x-21 should be 9x+21. This is because -3 in x-3, and -3x-7 in 5x²-3x-7 are both negative, so each term's product should be positive.
Also, in the third line, she wrote -3x²-15x² as -18x⁴ instead of -18x²,and similarly, she wrote -7x-9x as -16x² (however this is wrong anyway because step 2 was done incorrectly).
If we continued off from the second step with these corrected errors:
\(5x^3-3x^2-7x-15x^2+9x+21\\5x^3-18x^2+2x+21\)
Therefore, the correct simplification is \(5x^3-18x^2+2x+21\).
