If both the upstairs and downstairs switches are in the up position, the light will be off
How to determine if the light will be on?The given parameters are
Switches = 2 i.e. top and bottom
Also, we have:
When the upstairs switch is up and the downstairs switch is down, the light is turned on.
This means that the light is only on when the upstairs switch is up and the downstairs switch is down
Any other position of the switches, the light is off
From the question, we have
Both the upstairs and downstairs switches are in the up position
This is different from the required position to on the light
Hence, the light will be off

The diameter of the most popular brand of flying disc used in disc golf measures between 8 and 10 inches. Find the range of possible circumferences and areas for these flying discs to the nearest tenth.
The range of possible circumferences and areas for these flying discs are 25. 24 inches to 31. 42 inches and 50. 27 square inches and 78. 55 square inches respectively.
How to determine the circumferenceThe formula for circumference of a circle is expressed as;
Circumference = πd
Where;
π takes the value 3. 142d is the diameterCircumference for diameter of 8 inches
Circumference = 3. 142 × 8 = 25. 14 inches
Area = 1/ 4 πd² = 1/ 4 × 3. 142 × 8²
Area = 50. 27 square inches
Circumference for diameter of 10 inches
Circumference = 3. 142 × 10
Circumference = 31. 42 inches
Area = 1/ 4 × 3. 142 × 10²
Area = 78. 55 square inches
Thus, the range of possible circumferences and areas for these flying discs are 25. 24 inches to 31. 42 inches and 50. 27 square inches and 78. 55 square inches respectively.

A customer wanted to purchase a video game and realized that they were short $3.96 to be able to pay. Which value is the opposite of being short $3.96?
Using the absolute value function, the value that is the opposite of being short $3.96 is: x + 3.96.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, that is, |2| = |-2| = 2.
For this problem, the number is of $3.96, that is:
|x| = 3.96.
Hence:
Short of $3.96 means that x = -3.96.The opposite is the other solution, of x = 3.96.More can be learned about the absolute value function at https://brainly.com/question/24734454

What measure in linear-regression analysis provides the percent of variation in the dependent variable (y) that is explained by the regression equation?
The measure in linear-regression analysis that provides the percent of variation in the dependent variable as explained by the regression equation is the Coefficient of Determination.
What is the Coefficient of Determination?This is a measure that allows us to see just how much the variation in the dependent variable, is as a result of the independent variable and is therefore explained by the regression equation.
The Coefficient of Variation is very important because it helps to show the usefulness and accuracy of the regression equation model.

The variable y varies directly with the variable x.
If the value of x is 14, what is the value of y?
Given that the variable y varies directly with the variable x. If the value of x is 14, the value of y will be 21.
If the value of x is 14, what is the value of y?Proportional relationships are relationships between two variables where their ratios are equivalent.
A direct variation is expressed;
a ∝ b then a = kb
Where k is the proportionality constant.
Given the data in the question
a = 10b = 15k = ?First, we determine the proportionality constant.
a = kb
15 = k × 10
k = 15/10
k = 3/2
Now, if the value of x is 14, then the value of y will be;
a = kb
y = kx
y = (3/2) × 14
y = ( 3 × 14 )/2
y = 42/2
y = 21

Answer:
Value of y is 21, when x is 14.
Step-by-step explanation:
Now we have to,
→ find the value of y when x is 14.
Forming the formula,
→ k × 2 = x
→ k × 3 = y
Let's complete the given table,
→ k × 2 = x, k × 3 = y
→ 1 × 2 = 2, 1 × 3 = 3
→ 2 × 2 = 4, 2 × 3 = 6
→ 3 × 2 = 6, 3 × 3 = 9
→ 4 × 2 = 8, 4 × 3 = 12
→ 5 × 2 = 10, 5 × 3 = 15
→ 6 × 2 = 12, 6 × 3 = 18
→ 7 × 2 = 14, 7 × 3 = 21
Then the table will look like,
|| x || y |||| 2 || 3 |||| 10 || 15 |||| 14 || 21 ||Hence, y is 21 when x is 14.

In parabola , the coefficient of the squared expression is -3..
What on a graph is a parabola?
Drawing a parabola for the quadratic function f(x) = ax2 + bx + c results in a U-shaped curve. When an is smaller than zero, the parabola's graph is downward (or opens downward). When the value of an is greater than 0, the parabola's graph ascends (or opens up).Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3

A set of 10 scores has ss = 90. if the scores are a sample, the sample variance is ____, and if the scores are a population, the population variance is ____.
If the scores are a sample, the sample variance is 10, and if the scores are a population, the population variance is 9.
A set of 10 scores has SS = 90.
The formula in getting the population variance is
σ² = SS / N
where SS is the sum of squared deviation and N is the number of population.
Therefore, the population variance is
σ² = 90 / 10
σ² = 9
The formula in getting the sample variance is
σ² = SS /( n - 1)
where SS is the sum of squared deviation and n is the number of samples.
Therefore, the sample variance is
σ² = 90/ (10 - 1)
σ² = 90 / 9
σ² = 10
Therefore, if the scores are a sample, the sample variance is 10, and if the scores are a population, the population variance is 9.

Write the first six terms of the arithmetic sequence with the first term, a1, and common difference, d.

Answer:
2.5.8.11.14.17
Step-by-step explanation:
Start from 2 and add 3 every time
How to find the nth term in the sequence
3,6,9,12
The n th term of the series is 3n where n is the term of reference
As we can see that there is constant difference in the terms
12-9=3
9-6=3
6-3=3
We are made sure that it is the arithmetic progression
Common difference is the difference that is constantly subtracted or added to each term after the first term
Thus the common difference 'd' is 3 as per the calculations above
Now the first term is 3
We know that any N th term of arithmetic progression is given by the formula
Tn= a+ (n-1)*d
where a is the first term of the progression and n is the term of reference and d is the common difference
a=3
d=3
Therefore, nth term of the series is = Tn= 3 + (n-1) *3
Tn= 3+3n-3
Tn = 3n
Hence the n th term of the series is 3n where n is the term of reference

The circle below is centered at (4,-1) and has a radius of 3. What is it’s equation?
The equation of the area of the circle (x - 4)^2 + (y + 1)^2 = 9, that is, option B.
The standard form of an equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where, r = radius of the circle and (h, k) are the coordinates of the center of the circle.
Here, we are given that a circle is centered at (4,-1) and has a radius of 3.
Thus, r = 3
h = 4
and k = -1
Therefore, the equation of the circles will be-
(x - 4)^2 + (y - (-1))^2 = 3^2
(x - 4)^2 + (y + 1)^2 = 9

How to determine the parallel lines?The given equations are linear equations
Linear equations are represented as
y = mx + c
Where the slope of the linear equation is
Slope = m
Linear equations that have the same slope are parallel
This means that y = mx + c and y = mx + b are parallel lines because the slopes of the linear equations is m

Trina should buy the $6 packages to get 24 necklaces for the least price as calculated by using multiplication and division.
A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics .One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.At a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.From the attached table let us calculate the cost of buying necklaces in the various packages by using multiplication and division.
For the $4 package:
Number of necklaces in the package = 3
Number of packages Trina should buy (division used) = 24 ÷ 3 = 8
Cost of 8 packages =$ 4 × 8 = $ 32
For the $5 package:
Number of necklaces in the package = 4
Number of packages Trina should buy(division used) = 24 ÷ 4 = 6
Cost of 8 packages =$ 5 × 6 = $ 30
For the $6 package:
Number of necklaces in the package = 6
Number of packages Trina should buy(division used) = 24 ÷ 6 = 4
Cost of 8 packages =$ 6 × 4 = $ 24
Therefore buying the $24 package is the cheapest.
