Zachariah paid $126 for 6 concert tickets. At this rate, what is the cost of 10 concert tickets?

Hello there! I can help you with joy! :)

If we have 2 points, then we can find the slope using this formula:

m=\(\frac{y2-y1}{x2-x1}\)

y2=11

y1=-14

x2=11

x1=10

\(\frac{11-(-14)}{11-10}\)

\(\frac{11+14}{1}\)

Answer: A conclusion you reach using inductive reasoning is called conjecture.

Step-by-step explanation: Examining several specific situations to arrive at a conjecture is called inductive reasoning.

A conclusion that is arrived by inductive reasoning is called a conjecture.

An inductive reasoning is made following observable patterns. For instance when the patterns occurring in a sequence are closely monitored, inductive reasoning can be used to know what would be the next terms of the sequence.

A conjecture is a conclusion that one gets to while they are using the inductive type of reasoning.

Answer:

L=7

W=10

Step-by-step explanation:

W=2L-4

WL=70

(2L-4)L=70

2L^2-4L-70=0

2(L^2-2L-35)=0

2(L-7)(L+5)=0

L-7=0

so:

L=7 IS THE LENGTH OF THE RECTANGLE.

W=2*7-4

W=14-4

W=10 IS THE WIDTH OF THE RECTANGLE.

PROOF:

Answer:

1.66

---------

First find the value of 8 divided by 10 because they are in parentheses.

\(10/8 = 1.25\)

Divide 6 by 1.25

\(6 / 0.8 = 4.8\)

Then, divide by 4

\(4.8 / 4 = 1.2\)

Finally, divide 2 by 1.2

\(2 / 1.2 = 1.66\)

The answer should be 1.66 if you do the problem right to left(because of the order of operations).

If the dilation is centered at the origin, determine the vertices of polygon A′B′C′D′ are: D. A′(−2.4, 3.6), B′(−1.2, 1.2), C′(2.4, −1.2), D′(2.4, 2.4).

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 3/5 centered at the origin as follows:

Ordered pair A (-4, 6) → Ordered pair A' (-4 × 3/5, 6 × 3/5) = Ordered pair A' (-2.4, 3.6).

Ordered pair B (-2, 2) → Ordered pair B' (-2 × 3/5, 2 × 3/5) = Ordered pair B' (-1.2, 1.2).

Ordered pair C (4, -2) → Ordered pair C' (4 × 3/5, -2 × 3/5) = Ordered pair C' (2.4, -1.2).

Ordered pair D (4, 4) → Ordered pair D' (4 × 3/5, 4 × 3/5) = Ordered pair D' (2.4, 2.4).

Answer:

Step-by-step explanation:

log3(x+2)-log3(x)=1

Subtraction sign means you can divide the values inside the parintheses

log3(x+2/x)=1

split up the fraction into x/x and 2/x; x/x = 1

log3(1+(2/x))=1

Change of base - three to the first power = value in parintheses

3to1st=1+(2/x)

subtract 1 from both sides

2=2/x

divide both sides by 2

Answer:

The degrees of freedom for this problem are 21

Step-by-step explanation:

Degrees of freedom:

When testing an hypothesis involving two samples, the number of degrees of freedom is given by:

\(df = n_1 + n_2 - 2\)

In which \(n_1\) is the size of the first sample and \(n_2\) is the sample of the second sample.

In this question:

Samples of 9 and 14, so \(n_1 = 9, n_2 = 14\)

The degrees of freedom for this problem are

\(df = n_1 + n_2 - 2\)

\(df = 9 + 14 - 2 = 21\)

The degrees of freedom for this problem are 21

The required degree of freedom is 21.

Given that,

He randomly selects a sample of 9 lunch tickets from the city population resulting in a mean of $14.30 and a standard deviation of $3.40.

He randomly selects a sample of 14 lunch tickets from the suburban population resulting in a mean of $11.80 and a standard deviation $2.90.

He is using an alpha value of .10 to conduct this test.

We have to find,

The degrees of freedom for this problem are.

According to the question,

Degrees of freedom refers to the maximum number of logically independent values, which are values that have the freedom to vary, in the data sample.

Degrees of freedom are commonly discussed in relation to various forms of hypothesis testing in statistics, such as a chi-square.

When testing an hypothesis involving two samples, the number of degrees of freedom is given by,

\(Degree \ of \ freedom = n_1+n_2-2\)

Where, \(n_1\) is the size of the first sample and \(n_2\) is the sample of the second sample.

\(n_1 = 9 \ and\ n_2 = 14\)

Therefore,

\(Degree \ of \ freedom = 9+14-2\\\\Degree \ of \ freedom = 21\)

Hence, The required degree of freedom is 21.

Answer: x = -3/2 , x = -1 1/2 , x = -1.5

Step-by-step explanation:

6/-4.5 = 8/4x

first determine the defined range --> x ≠ 0

cancel out the common factor 4 --> 6/-4.5 = 2/x

the convert the decimal into a fraction --> 6/-9/2 = 2/x

now use -a/b = a/-b = -a/b to rewrite the fraction --> 6/-9/2 = 2/x

then simplify the complex fraction --> -4/3 = 2/x

simplify the equation using cross-multiplication --> -4x=6

divide both side of the equation by -4 --> x = -3/2 , x ≠ 0

lastly, check if the solution is in the defined range --> x = -3/2

solution : x = -3/2

Alternative form: x = -1 1/2 , x = -1.5 (simplified)

Answer:

(x - 10)(x - 2) = 0, x = 10, 2

Step-by-step explanation:

x² - 12x = -20

Add 20 to both sides.

x² - 12x + 20 = 0

To complete the square, find values that add up to the middle coefficient and multiply to the final number. In this case, -10 and -2 add to -12 and multiply to 20.

(x - 10)(x - 2) = 0

Now solve each individual pair.

x - 10 = 0

x = 10

x - 2 = 0

x = 2

Answer:

Step-by-step explanation :

N = number of nickels

D = number of dimes

Q = number of quarters

`

252 = N + D + Q <---- Equation 1

D = 3(N+Q) <---- Equation 2

24.85 = 0.05N + 0.10D + 0.25Q <---- Equation 3

We a have set of three linear equations to solve for three unknowns N, D, and Q.

Rearranging the equations we have :

N + D + Q = 252

3N - D + 3Q = 0

0.05N + 0.10 D + 0.25Q = 24.85

Solving the set of linear equations, we end up with :

N = 49

D = 189

Q = 14

Answer:

  a) sound system: $500

  b) navigation system: $1000

Step-by-step explanation:

The cost of the car with its upgrades (before tax) is ...

  $48,346.31/1.065 = 45,395.60

This means the total cost of the sound and navigation upgrades is ...

  $45,395.60 -43,895.60 = $1500

The ratio of sound system cost to navigation system cost is 1 : 2, so the sound system accounts for 1/(1+2) = 1/3 of the cost of the upgrades.

a) The upgraded sound system cost is 1/3 × $1500 = $500.

b) The upgraded navigation system cost is 2/3 × $1500 = $1000.

Step-by-step explanation:

The slope-intercept form of the equation is y = (4/5)x -1.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that slope=4/5 passing through (5,3). The equation of the line can be written as,

y = mx + c

3 = ( 4 x 5/5) + c

Answer: 15 inches

Step-by-step explanation:

An equilateral triangle has three equal sides, so if the perimeter of the triangle is 45 inches, then each side must be 45 inches divided by 3, which gives us:

45 in ÷ 3 = 15 in

Therefore, the length of each side of the flag is 15 inches.

The given geometric sequence has the common ratio, r = -2/3, and the value of the 4th term, a₄ = -8/3.

A geometric sequence is a special series where every term is the product of the previous term and a common ratio.

The first term of a geometric sequence is represented as a, the common ratio as r, and the n-th term as aₙ, which is calculated as, aₙ = a.rⁿ⁻¹.

In the question, we are asked to find the common ratio and the 4th term of the geometric sequence, 9, -6, 4, ........

The first term of the sequence, a = 9.

The second term of the sequence, a₂ = -6.

By the formula of the n-th term, aₙ = a.rⁿ⁻¹, we can show that:

a₂ = a.r²⁻¹.

Substituting the values, we get:

-6 = 9(r²⁻¹),

or, r²⁻¹ = -6/9,

or, r = -2/3.

Thus, the common ratio of the given geometric sequence is -2/3.

The 4th term can be calculated using the formula of the n-th term, aₙ = a.rⁿ⁻¹ as:

a₄ = a.r⁴⁻¹ = a.r³.

Substituting the values, we get:

a₄ = 9(-2/3)³,

or, a₄ = 9.(-8/27),

or, a₄ = -8/3.

Thus, the 4th term of the given geometric sequence is -8/3.
