Solve for the value of X 130 degrees X+134

A system of 4 linear equations in 3 variables x, y, z can have at most one solution.

It is because a system with more than three equations and only three variables will not have a unique solution due to the fact that the dimension of the solution space of 3-dimensional equations is three, so adding an extra equation will result in an over-determined system.

In other words, there are not enough variables in the system to meet the requirements of all the equations, which leads to an over-determined system where there is either no solution or a unique solution. If the system has exactly two solutions, it means that the solution space of the system of equations has a dimension greater than 3, which contradicts the fact that the dimension of the solution space of a system of 3-dimensional equations is 3.

Answer:

Number of sodas sold: 78

Number of hot dogs sold: 24

Step-by-step explanation:

Number of sodas sold = x

Number of hot dogs sold = x - 54

Total number of sodas and hot dogs = x + x - 54 = 2x - 54

Total number = 102

2x - 54 = 102

2x = 156

x = 78

Number of sodas sold = x = 78

Number of hot dogs sold = x - 54 = 78 - 54 = 24

Answer:

Number of sodas sold: 78

Number of hot dogs sold: 24

Answer:

B, -3/4

Step-by-step explanation:

Slope can be found by using rise over run. From point x the line drops three points making the rise -3, and it goes to the right four points making the run 4. That makes our answer -3/4.

If the diagonal of a rhombus id x-4d and x+ 4d then the area of rhombus is (x² - 16d²) / 4 unit²

In a rhombus, the diagonals are perpendicular bisectors of each other, and they divide the rhombus into four congruent right triangles. Let's call the length of one half of the diagonal "a" and the length of the other half of the diagonal "b". So we have:

a = (x - 4d) / 2

b = (x + 4d) / 2

The area of a rhombus can be calculated as half the product of its diagonals, or as half the product of its side lengths:

Area = (1/2) × a × b × 2

Area = a × b

Substituting the expressions for "a" and "b" from above, we get:

Area = [(x - 4d) / 2] × [(x + 4d) / 2]

Area = (x² - 16d²) / 4

Therefore, the area of the rhombus is (x² - 16d²) / 4 square units.

For the poset or the ordered set given in question

a) The maximal elements are 27, 48, 60, and 72.

b) The minimal elements are 2 and 9.

c) There exists no greatest element.

d) There exists no least element.

e) The upper bounds of {2, 9} are 18, 36, and 72.

f) The least bound of {2, 9} is 18.

g) The lower bounds of {60, 72} are 2, 4, 6,  and 12.

h) The greatest lower bound of {60, 72} is 60.

A poset is a partially ordered set that helps to establish and expand the logical idea of an ordering and arrangement of elements of a set.

In a poset we can find the greatest, least, upper bounds,

An element a of x will be the maximal element provided that there exists no b ∈ x such that a < b.

An element a of x will be the minimal element provided that there exists no b ∈ x such that b < a.

An element a of x will be the greatest element provided that b ≤ a for all b ∈ x.

An element a of x will be the least element provided that a ≤ b for all b ∈ x.

To find the upper bound of the set {2, 9}, with respect to the poset, is to find all of the elements that both 2 and 9 divides. These elements are 18, 36, and 72.

To find the least upper bound of the set {2, 9} is to consider the upper bounds, and find the one that divides the others.

To find the lower bounds of the set {60, 72}, with respect to the poset, is to find the elements that divide into 60 and 72. These elements are 2, 4, 6, and 12.

To find the greater lower bound of the set {60, 72}, is to consider the lower bounds, and see which one is divisible by them all.

To find the missing sides and angles of a right triangle with side b = 32 and side c = 51, we can use the Pythagorean theorem and trigonometric ratios.

Let's denote the missing side as a and the angles as A and B, with B being the right angle.

Using the Pythagorean theorem, we know that in a right triangle, the sum of the squares of the two legs (a and b) is equal to the square of the hypotenuse (c):

a^2 + b^2 = c^2

Plugging in the given values, we have:

a^2 + 32^2 = 51^2

a^2 + 1024 = 2601

a^2 = 1577

a ≈ 39.73

Therefore, the length of the missing side a is approximately 39.73.

The answer to your question depends on the specific context and analysis being referred to. In statistical analysis, a coefficient is a measure of the strength and direction of the relationship between two variables. The term "statistically significant" refers to whether a result or relationship observed in a sample is likely to hold true in the larger population, based on the probability of obtaining such a result by chance.

If the coefficient for population is found to be statistically significant at a certain level, this means that the relationship between population and the outcome being studied is unlikely to have occurred by chance alone.

In your question, the possible answers suggest different levels of statistical significance, ranging from 1% to 49.5%. Generally, a standard level of significance is set at 5%, meaning that there is a 95% chance that the relationship observed in the sample is true for the population as a whole. If the coefficient for population is found to be statistically significant at the 5% level, this would suggest that the relationship is strong enough to be confident that it holds true in the larger population.

However, if the coefficient is only statistically significant at a higher level (such as 1%), this suggests an even stronger relationship between population and the outcome being studied. On the other hand, if the coefficient is not statistically significant at any level (i.e. it is "insignificant"), this suggests that there is not enough evidence to support a relationship between population and the outcome, or that any relationship that does exist is weak and likely due to chance.

Without more context or information about the specific analysis being conducted, it is difficult to determine which of these answers is correct. However, if a coefficient for population is found to be statistically significant, it is important to provide an explanation of what this means in the context of the research question and the data being analyzed.

The probability of the sets are solved and

a) n(P U Q) = 85%

b) n(P ∩ Q) = 20%

c) n(only P) = 35%

d) n(only Q) = 30%

Given data ,

P and are the subsets of universal set U

And , n (p) = 55% n (Q) = 50% and n(PUO)complement = 15%

Now , we'll use the formula for the union and intersection of sets:

n(P U Q) = n(P) + n(Q) - n(P ∩ Q)

n(P ∩ Q) = n(P) + n(Q) - n(P U Q)

n(only P) = n(P) - n(P ∩ Q)

n(only Q) = n(Q) - n(P ∩ Q)

We're given that:

n(P) = 55%

n(Q) = 50%

n(P U Q)' = 15%

To find n(P U Q), we'll use the complement rule:

n(P U Q) = 100% - n(P U Q)'

n(P U Q) = 100% - 15%

n(P U Q) = 85%

Now we can substitute the values into the formulas above:

(i)

n(P U Q) = n(P) + n(Q) - n(P ∩ Q)

n(P ∩ Q) = n(P) + n(Q) - n(P U Q)

n(P ∩ Q) = 55% + 50% - 85%

n(P ∩ Q) = 20%

(ii)

n(P ∩ Q) = 20%

(iii) n(only P) = n(P) - n(P ∩ Q)

n(only P) = 55% - 20%

n(only P) = 35%

(iv)

n(only Q) = n(Q) - n(P ∩ Q)

n(only Q) = 50% - 20%

n(only Q) = 30%

Hence , the probability is solved

The sum of the first fifteen terms of the given sequence is 220.

The given sequence can be expressed as: \($2, 8, 14, \dots$\), in which each term is six more than the preceding term. This is an arithmetic sequence, where the common difference between terms is 6. The formula to calculate the sum of the first n terms of an arithmetic sequence is given by \($S_n = \frac{n}{2}(a_1 + a_n)$\), where \($a_1$\) is the first term and \($a_n$\) is the nth term.

In the given sequence, the first term \($a_1$\) is 2 and the 15th term \($a_n$\) is 42. So, plugging these values to the formula gives us, \($S_{15} = \frac{15}{2}(2+42) = \frac{15\times 44}{2} = 220$\).

f(x) is increasing on the intervals (−∞, π/4) and (5π/4, ∞), and decreasing on the interval (π/4, 5π/4).

To determine the intervals on which f(x) = 3sin(x) + 3cos(x) is increasing and decreasing, we need to find the derivative of f(x) and examine its sign.

f'(x) = 3cos(x) - 3sin(x)

To find where f'(x) = 0, we set the derivative equal to zero and solve:

3cos(x) - 3sin(x) = 0

cos(x) - sin(x) = 0

From this equation, we can see that it is satisfied when x = π/4 and x = 5π/4.

Now, we analyze the sign of f'(x) in different intervals:

For x < π/4: f'(x) > 0, so f(x) is increasing.

For π/4 < x < 5π/4: f'(x) < 0, so f(x) is decreasing.

For x > 5π/4: f'(x) > 0, so f(x) is increasing.
