Answer:
Money spent on playstation games per week: =$8169861
Money spent on other video games per week: = $5542467
Step-by-step explanation:
Hi to answer this first, we have to calculate how much Americans spend on non Playstation video games. So, we have to subtract the money spent on Sony Playstation games to the total money spent:
$1958904.00-$1167123.00= 791781 on other video games per day
Now, since each week has 7 days. We have to multiply each daily amount by 7.
Money spent on playstation games per week: $1167123.00 x 7=8169861
Money spent on other video games per week: $791781 x 7= 5542467
What is the fewest number of intersection points that two planes can have?
Answer: 4 points
Step-by-step explanation:
The minimum number of points needed to define two distinct planes is 4 points. Two distinct planes can be defined by 4 points under the conditions that the two distinct planes intersect at a line, and two points exist on that line that are shared between the planes.
Answer:
One line of intersection (three points of intersection)
Step-by-step explanation:
When two planes intersect, they don't form points of intersection, but they form a line of intersection.
From equation of a line,
[tex]{ \tt{ax + by + cz = 0}}[/tex]
x, y, z are points of intersection

However, the angle described by when x = 0 are;
E) Either 90° or 270°
Which method can be used to find the measure of the required angle?
The question appears to be incomplete. The possible other part of the question is as follows;
When x = 0, and the calculator is used to find the tangent, the calculator indicates that the value is undefined, such that the calculator will not be able to give the value of the angle that corresponds with a value of x = 0.
What must the angle in degrees be when x = 0
Solution;
[tex]tan( \theta) = \frac{ \Delta y}{\Delta x} = \frac{y - value}{x - value} [/tex]
When x = 0, we have;
[tex]tan( \theta) = \frac{y - value}{0} = \infty [/tex]
However, when x = 0, the terminal side have rotated from the initial side to the positive or negative side of the ordinate, which corresponds to 90° or 270°, which are located on the ordinate of the graph

When using the inverse tangent function on a calculator to find the angle of a vector in the x-y plane, it is important to understand the limitations and considerations involved. The inverse tangent function, commonly denoted as arctan or atan, returns the angle whose tangent is a given value. However, special attention should be given to the range of the output and the quadrant of the angle. Additionally, some calculators have a two-argument inverse tangent function that considers both the x and y components of the vector, providing a more accurate result. To find the angle of a vector in the x-y plane using the inverse tangent function on a calculator, we typically use the atan or arctan function. The function takes a single argument, which is the ratio of the y-coordinate to the x-coordinate of the vector. It returns the angle in radians whose tangent is equal to that ratio. However, it's important to consider the limitations of the inverse tangent function. The output of the function is typically in the range of -π/2 to π/2 (-90 degrees to 90 degrees). This means that the function can only provide angles within this range. If the vector falls in the second or third quadrant (where the x-coordinate is negative), the function will return an angle between -90 degrees and 90 degrees. To obtain the correct angle in these cases, we need to add or subtract 180 degrees, depending on the quadrant. Some calculators also have a two-argument inverse tangent function, often denoted as atan2 or arctan2. This function takes both the x and y components of the vector as arguments. It provides a more accurate result by considering the signs of both components and the quadrant of the angle. This eliminates the need for additional calculations to determine the correct quadrant. In conclusion, when using the inverse tangent function on a calculator to find the angle of a vector in the x-y plane, we should be aware of the range of the output and the quadrant in which the vector lies. For more accurate results, it is recommended to use the two-argument inverse tangent function (such as atan2 or arctan2) if available on the calculator, as it handles the quadrant determination automatically.

3 Answers: Choice A, Choice B, Choice E
=========================================================
Explanation:
We have four copies of x in the original expression. So that accounts for the 4x. In other words, 4x = x+x+x+x. Multiplication is used for repeated addition.
Also, the other terms add to 15+5+15+5 = 20+20 = 40
Therefore, we end up with 4x+40 from choice A.
-----------------------------
Once we get to 4x+40, we can factor out 2 from it like so
4x+40
2*2x + 2*20
2(2x+20) which is choice B
I used the distributive property to factor. That rule is a(b+c) = ab + ac
-------------------------------
Choice C is not one of the answers. We can determine this fairly quickly by noting that the expression in choice C talks about a quadratic, but the original expression given to us is linear.
Choice D is a similar story to choice C.
--------------------------------
Choice E is another answer
This is because we have two copies of (x+15), so that gives 2(x+15)
We also have two copies of (x+5) to get 2(x+5)

The sum of 2 integers is 7 and the sum of their squares is 37 what is the integers
Answer:
[tex]1[/tex] and [tex]6[/tex].
Step-by-step explanation:
Let [tex]x[/tex] denote one of the integers. Since the two integers add up to [tex]7[/tex], the other integer would be [tex](7 - x)[/tex].
The sum of the squares of these integers is [tex]37[/tex]. In other words:
[tex]x^{2} + (7 - x)^{2} = 37[/tex].
Expand [tex](7 - x)^{2}[/tex] using binomial expansion. Simplify and rewrite this equation and solve for [tex]x[/tex].
[tex]2\, x^{2} - 14\, x + 12 = 0[/tex].
[tex]x^{2} - 7\, x + 6 = 0[/tex].
Using the quadratic formula or factorization, [tex]x = 1[/tex] or [tex]x = 6[/tex]. Thus, the two integers are [tex]1[/tex] and [tex]6[/tex].
37 centimeters is the same as how many inches? Hint: 1 cm ≈ 0.39 in Round your answer to the nearest tenth. HELP PLEASE!!!
37 centimeters is equal to approximately 14.5 inches.
In both the British imperial and American customary systems of measurement, the inch serves as a unit of length. It is equal to 1/12 of a foot or 336 yards.The International System of Units (SI) uses centi as the prefix for a factor of 1/100, making a centimeter (international spelling) or centimeter (American spelling) (SI symbol cm) equivalent to one tenth of a meter. In the now-outdated centimeter-gram-second (CGS) system of units, the centimeter served as the fundamental unit of length.We know that 1 cm is equal to 0.39 inches.
So to convert 37 cm to inches we multiply 37 with 0.39
37×0.39=14.47 inches
The length is approximately 14.5 inches (rounded to the nearest tenth)

There are a total of seven combinations where arranging the digits 1 to 9 into three groups (one group of two digits, one group of three digits, and one group of four digits) results in a four-digit number when the first group is multiplied by the second group.
Here, we have to form the three groups with the digits 1 to 9, we need to consider that the first group of two digits multiplied by the second group of three digits should result in a four-digit number.
The third group will consist of the remaining four digits.
Let's try different combinations:
Group 1 (two digits): 1 and 2
Group 2 (three digits): 3, 4, and 5
Group 3 (four digits): 6, 7, 8, and 9
Now, let's calculate the product of the first group (1 and 2) and the second group (3, 4, and 5):
12 * 345 = 4140
So, when we arrange the digits 1 to 9 as described above, we get the product 4140, which is a four-digit number.
We can also verify the other six possible combinations using different arrangements of the digits into three groups, and each combination should result in a four-digit number when the first group is multiplied by the second group.
Here are the other six possible combinations:
Group 1 (two digits): 1 and 3, Group 2 (three digits): 2, 4, and 5, Group 3 (four digits): 6, 7, 8, and 9
13 * 245 = 3185
Group 1 (two digits): 1 and 4, Group 2 (three digits): 2, 3, and 5, Group 3 (four digits): 6, 7, 8, and 9
14 * 235 = 3290
Group 1 (two digits): 1 and 5, Group 2 (three digits): 2, 3, and 4, Group 3 (four digits): 6, 7, 8, and 9
15 * 234 = 3510
Group 1 (two digits): 2 and 3, Group 2 (three digits): 1, 4, and 5, Group 3 (four digits): 6, 7, 8, and 9
23 * 145 = 3335
Group 1 (two digits): 2 and 4, Group 2 (three digits): 1, 3, and 5, Group 3 (four digits): 6, 7, 8, and 9
24 * 135 = 3240
Group 1 (two digits): 2 and 5, Group 2 (three digits): 1, 3, and 4, Group 3 (four digits): 6, 7, 8, and 9
25 * 134 = 3350
So, there are a total of seven combinations where arranging the digits 1 to 9 into three groups (one group of two digits, one group of three digits, and one group of four digits) results in a four-digit number when the first group is multiplied by the second group.

Using the distributive property, the equivalent expressions are given as follows:
3(937) = 3(900) + 3(30) + 3(7).11(143) = 11(100) + 11(40) + 11(3).9(821) = 9(800) + 9(20) + 9(1).5(209) = 5(200) + 5(0) + 5(9).6(342) = 6(300) + 6(40) + 6(2).What is the distributive property?The distributive property is when the outside term of an expression multiplies all the inside terms, keeping the inside operations, as the following example:
a(b + c) = ab + ac.
For this problem, the numbers can be decomposed as follows:
937 = 900 + 30 + 7.143 = 100 + 40 + 3.821 = 800 + 20 + 1.209 = 200 + 0 + 9.342 = 300 + 40 + 2.Applying the distributive property, the equivalent expressions are:

Answer:
Down Here ↓↓↓↓
Step-by-step explanation:
Hello!
Let's take an example: x > y
The rule that we currently have would state that -x < -y.
Now, let's substitute values for x and y. Say x is 5 and y is -3.
5 is greater than -3 (x > y), but -5 would be less than -3. (-x < -y). Hence the inequality would be true.
We can also take a look at this graphically on a number line. Turning a number negative is simply reflecting it over value 0.
As you can see, flipping the signs would change the values. To keep the inequality accurate, we reverse the inequality sign as well.
Write an equation of the line that passes through the point (1,5) and is (a) parallel to the line y = 3x-5 and (b) perpendicular
to the line y = 3x - 5.
Answer:
[tex]\textsf{An equation of the parallel line is $y = \boxed{3x+2}$}[/tex]
[tex]\textsf{An equation of the perpendicular line is $y = \boxed{-\dfrac{1}{3}x+\dfrac{16}{3}}$}[/tex]
Step-by-step explanation:
Point-slope form of a linear equation:
[tex]\boxed{y-y_1=m(x-x_1)}[/tex]
Where:
m is the slope.(x₁, y₁) is a point on the line.Given:
Equation: y = 3x - 5Point: (1, 5)Part (a)If two lines are parallel, they have the same slope.
Therefore, the slope of the line that is parallel to the given equation is 3.
To find the equation of the line, substitute the found slope and the given point into the point-slope form of a linear equation:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-5=3(x-1)[/tex]
[tex]\implies y-5=3x-3[/tex]
[tex]\implies y-5+5=3x-3+5[/tex]
[tex]\implies y=3x+2[/tex]
Part (b)If two lines are perpendicular, their slopes are negative reciprocals.
Therefore, the slope of the line that is perpendicular to the given equation is -¹/₃.
To find the equation of the line, substitute the found slope and the given point into the point-slope form of a linear equation:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-5=-\dfrac{1}{3}(x-1)[/tex]
[tex]\implies y-5=-\dfrac{1}{3}x+\dfrac{1}{3}[/tex]
[tex]\implies y-5+5=-\dfrac{1}{3}x+\dfrac{1}{3}+5[/tex]
[tex]\implies y=-\dfrac{1}{3}x+\dfrac{16}{3}[/tex]
a test shows that 10 out of 100 gadgets are defective. in a random sample of two gadgets are chosen the probability that both are defective is
The probability of selecting both defective gadgets out of 100 gadgets is 1/110, which is calculated using the basic concepts of probability theory.
What is a random experiment?
An experiment that is repeated several times and produces more than one possible outcome is called as the random experiment. It contains a well-defined set of values which constitutes a sample space. Eg: Rolling a die, tossing a coin etc.
Calculation of the probability of selecting both gadgets as defective
The total amount of gadgets = 100
Number of defective gadgets = 10
The probability of selecting a defective gadget is 10 / 100 or 1 / 10
Now, the total number of gadgets and defective gadgets are decreased by 1
So, the probability of selecting another gadget as defective is 9 / 99 or 1 / 11
P(E) = P(when two selected gadgets are defective) = 1 / 10 x 1 / 11
P(E) = 1 / 110
Hence, the probability of selecting both defective gadgets is 1/110.

Isaac bought two DVD's and spent over 50 . Use indirect reasoning to show that at least one of the DVD's he purchased was over 25 .
By assuming that both DVD's cost $25 or less, we will reach an absurd. In that way we conclude that at least one of the two DVD's costs over $25.
How to use the indirect reasoning?
We know that Isaac bought two DVD's and spent over $50.
Let's define the variables:
x = cost of the DVD 1y = cost of the DVD 2Because the cost is over $50 we can write the inequality:
x + y > $50
Here we want to prove that at least one of the two DVD's costed over $25, now let's find an absurd here, let's assume that neither of the DVD's costed over $25, then we can write:
x ≤ $25
y ≤ $25
So we have a set of 3 inequalities:
x + y > $50
x ≤ $25
y ≤ $25
Now, the maximum values that x and y can take are $25, if we use these values in the first inequality we will get:
$25 + $25 > $50
$50 > $50
So this is an absurd, this means that we can't assume that neither of the DVD's costs over $25, then we conclude that at least one of the DVD's costs over $25, which is what we wanted to prove.
