If the current is 2.2 A, it falls within the 2% tolerance range of 2.156 A to 2.244 A and would be considered correct.
To determine if 2.2 A falls within the 2% tolerance range, we first need to establish what the expected current value is. If the expected current value is not specified, it's best to use the maximum rated current value as the expected value.
Once we have the expected current value, we can calculate the tolerance range. Tolerance is expressed as a percentage of the expected value, and in this case, it's 2%.
So the tolerance range is:
(Expected Value) * (Tolerance Percentage) = Tolerance Range
For example, if the expected value is 2.2 A, then the tolerance range would be:
2.2 * 0.02 = 0.044
The tolerance range represents the amount by which the actual current can deviate from the expected value and still be considered acceptable. In this case, the tolerance range is 0.044 A, so the acceptable range for the current would be:
(Expected Value - Tolerance Range) to (Expected Value + Tolerance Range)
2.2 - 0.044 to 2.2 + 0.044 = 2.156 to 2.244

intuitively, what do we expect to have when the error term's variance increases when we estimate a simple linear regression model?
When the variance of the error term increases in a simple linear regression model, it indicates a less accurate model with a high degree of uncertainty in its predictions.
Regression is a statistical method used to model the relationship between two variables, where one of the variables is dependent on the other.
Simple linear regression is a type of regression where the relationship between the dependent variable and the independent variable is modeled as a linear equation.
Mathematically, let's consider the simple linear regression equation as:
Y = β0 + β1X + ε
Where Y is the dependent variable, X is the independent variable, β0 and β1 are the coefficients of the regression equation, and ε is the error term.
The variance of the error term, Var(ε), is a measure of the spread of the residuals. A large variance of the error term indicates that the residuals are spread out over a large range, and thus, the regression model's predictions may not be very accurate.
In other words, a large variance of the error term means that the model has a high degree of uncertainty in its predictions, leading to a larger deviation between the actual and predicted values.

Which equation best represents the relationship between x and y in the graph?
y = 1500 + 150x, this is correctly represents the relationship between x and y in the graph. This can be solved using the slope formula.
What is slope?Slope, An evaluation of a line's inclination with respect to the horizontal using numbers. The slope of any line, ray, or line segment in analytical geometry is defined as the proportion of the vertically to the horizontally distance between the two points on the line ("slope equals rise over run").
(0, 1500) to (2, 1800)
thus, slope = (y₂ - y₁) / (x₂ - x₁)
or, slope = 300 / 2
or, slope = 150
So, y - 1500 = 150x

The exponential decay model for the investment of $38,976 with decreased rate 3.5% for 't' years is equal to option b. 38,976 (0.965 )^t.
Invested amount by Kindred = $38,976
Each year investment decreased by 3.5%
Number of years represented by 't' = 3 years
Amount decreased by 100 - 3.5% = 96.5%
= 0.965
Total amount decreased in three years = $38,976 × ( 0.965 )³
= $35,025.085
Exponential decay model for 't' years at the same rate is given by the equation :
= 38,976 × ( 0.965 )^t

solve these simultaneous equations
4a+3b=-9
2a+5b=-1
The solution to the system of equations 4a + 3b = -9 and 2a + 5b = -1 is a = 12, b = -5, found through substitution method.
Simultaneous equations are a set of equations with multiple variables, and the solution of these equations gives us the values of the variables that make all the equations true at the same time. To solve these equations, we can use elimination, substitution or matrices method.
Here, the given set of simultaneous equations is
4a + 3b = -9
2a + 5b = -1
One way to solve this is by substitution, where we solve one equation for one variable and substitute that expression into the other equation. Solving the first equation for "a", we get:
a = -3b - 3
Substituting this expression into the second equation, we get:
2(-3b - 3) + 5b = -1
Expanding the left-hand side, we get:
-6b - 6 + 5b = -1
Combining the like terms, we get:
-b - 6 = -1
Adding b and 6 to both sides, we get:
-b = 5
Finally, dividing both sides by -1, we get:
b = -5
Substituting the value of b back into the expression for a, we get:
a = -3(-5) - 3 = 15 - 3 = 12
So the solution to the system of equations is:
a = 12, b = -5

No, the given sequence is neither an arithmetic nor geometric sequence as there is no common difference nor common ratio.
Pattern for difference is dₙ = dₙ₋₁ + 1.
Pattern of the sequence is :
15, 17, 20, 24, 29,.....

29 + 6 = 35
35 + 7 = 42 and so on.
Difference of two consecutive terms are related by :
dₙ = dₙ₋₁ + 1
Common difference is not same for all the terms so it is not arithmetic sequence.
Common ratio is also not constant implies it is not geometric sequence.

7. to survey the opinions of bleacher fans at wrigley field, a surveyor plans to select every one-hundredth fan entering the bleachers one afternoon. will this result in a simple random sample of cub fans who sit in the bleachers?
The survey does not result in a simple random sample of Cubs fans who sit in the bleachers. So, option E) is correct.
Simple random sampling is a method of selecting a sample from a population such that each element in the population has an equal chance of being selected. This is achieved by using a random number generator or by randomly assigning a number to each element in the population and then selecting a sample based on those numbers.
In this case, the survey plan to select every one-hundredth fan entering the bleachers is not a simple random sample because not every sample of the intended size has an equal chance of being selected. For example, the first fan entering the bleachers has a 1 in 100 chance of being selected, while the second fan has a 2 in 100 chance of being selected. This creates a non-uniform selection process, which is not representative of simple random sampling.
Therefore, the survey plan to select every one-hundredth fan entering the bleachers results in a form of systematic sampling, which is not a simple random sample.

F(x)=-6x^4x+2x^2+12 G(x)=-2x^3+6x^2-x-1

How many chocolate bars did Class A and Class C sell altogether?
Class A and Class C sell 187.5 altogether
How many chocolate bars did Class A and Class C sell altogether?Represent the classes with their initials
So, we have
B = 2A
C = 3/4 * B = 3/4 * 2A
C = 3/2A
The total number of bars they had initially was
A + B + C = Total
A + 2A + 3/2A = Total
Total = 4.5A
The average number of bars the 3 classes had initially was 225,
So
4.5A = 225
A = 75
For Class A and Class C together, we have
