Answer:

6.5 weeks without parental help, 3.5 weeks with help from your parents.

Step-by-step explanation:

The Equation is:

Y = 20x

Y = Starting price for bikes

X = # of weeks

Therefore:

$130 = 20x

This can be simplified by solving for x

x = 130/20

x = 6.5 weeks

If your parents gave you $60 to help buy the bike the equation would be written as:

Y = 20x + 60

$130 = 20x + 60

Subtract 60 from both sides to get:

$70 = 20x

Solve for x

x = 70/20

x = 3.5 weeks

The function giving the distance between the point (0,-6) and the line y = 8x - 5 is: S = 47 / sqrt(65).

To find the point on the line closest to the point (0,-6), we can find the perpendicular distance from the point (0,-6) to the line y = 8x - 5. The point on the line closest to (0,-6) will be the point on the line that is intersected by the perpendicular line.

The slope of the given line is 8, so the slope of any line perpendicular to it will be -1/8. Let (a,b) be the point on the line y = 8x - 5 that is closest to (0,-6). The equation of the line passing through (0,-6) with slope -1/8 is:

y + 6 = (-1/8)x

Simplifying this equation, we get:

y = (-1/8)x - 6

The point (a,b) will lie on both the given line and the perpendicular line. Therefore, we can substitute y = 8x - 5 in the equation y = (-1/8)x - 6 to obtain:

8x - 5 = (-1/8)x - 6

Solving for x, we get:

x = 37/65

Substituting x = 37/65 in y = 8x - 5, we get:

y = 231/65

Therefore, the point on the line y = 8x - 5 closest to the point (0,-6) is (37/65, 231/65).

The distance S between the point (0,-6) and the line y = 8x - 5 can be found by using the formula:

S = |ax + by + c| / sqrt(a^2 + b^2)

where a, b, and c are the coefficients of the general form of the line equation, which is ax + by + c = 0.

In this case, the equation of the line is y - 8x + 5 = 0. Therefore, a = -8, b = 1, and c = 5. Substituting these values in the formula for S, we get:

S = |(-8)(0) + (1)(-6) + 5| / sqrt((-8)^2 + 1^2)

= 47 / sqrt(65)

Therefore, the function giving the distance between the point (0,-6) and the line y = 8x - 5 is:

S = 47 / sqrt(65)

The correct alternative, based on the parallel, triangle sum, and isosceles triangle criteria, is 2.

Alternative 1

Since the base angle of an isosceles triangle is 52 degrees, let's say the third angle is x, and according to the triangle sum property,

x + 2 * 52 = 180,

x = 76.

triangle at the base

32 + 2x = 180 (triangle sum property for isosceles triangle)

x = 74

In accordance with the triangle sum property for isosceles triangles, the figure demonstrates that the base angle of the triangle at its base is also equal to 76.

False choice: Angles 74 and 76 are not equal.

Alternative 2:

x + 2 * 76 = 180 (triangle sum property for isosceles triangle)

x = 28

The diagram demonstrates that the triangle at the base angle has angle = 28.

124 + 2x = 180 (triangle sum property for isosceles triangle)

x = 28

Since the two angles 28 and 28 are equivalent, the choice is correct.

The vertex of the Quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

The vertex of a quadratic function given the y-intercept and x-intercept, we need to determine the axis of symmetry, which is the line that passes through the vertex. The x-coordinate of the vertex will be the midpoint between the x-intercepts, while the y-coordinate will be the same as the y-intercept.

Given that the y-intercept is (5, 0) and the x-intercept is (0, 80), we can determine the x-coordinate of the vertex by finding the midpoint of the x-intercepts. The x-coordinate of the midpoint is simply the average of the x-values:

x-coordinate of vertex = (0 + 0) / 2 = 0 / 2 = 0

Since the y-coordinate of the vertex is the same as the y-intercept, the vertex will have the coordinates (0, 0).

Therefore, the vertex of the quadratic function is (0, 0).

In conclusion, the vertex of the quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

Answer: 13xc-7

Step-by-step explanation:

A high correlation coefficient (either positive or negative) indicates that there is a high level of consistency between the two variables. The correct option is B. Correlation is a statistical method used to measure the strength and direction of the relationship between two variables.

When one variable increases as the other increases, this is known as a positive correlation. In contrast, when one variable decreases as the other increases, this is known as a negative correlation. Correlation Coefficient: Correlation coefficients are used to quantify the relationship between two variables. The range of values for the correlation coefficient is -1.0 to 1.0. A value of 1.0 represents a perfect positive correlation, indicating that as one variable increases, the other also increases in a linear fashion. A value of -1.0 indicates a perfect negative correlation, indicating that as one variable increases, the other decreases in a linear fashion. A value of 0.0 indicates that there is no correlation between the variables. The stronger the correlation, whether positive or negative, the closer the correlation coefficient is to 1 or -1.

Answer:

4^3 ➡ 4 × 4 × 4 ➡ 64

4^2 ➡ 4 × 4 ➡ 16

4^1 ➡ 4 ➡ 4

Step-by-step explanation:

The exponent represents how many times you're multiplying the base number by its self.

For example: In the first row, that's already filled in, 4^4 is the same as 4 × 4 × 4 × 4, not because you are multiplying 4 by the exponent, but because you're multpying 4 by its self 4 times.

(The same goes for the rest of the numbers.)

Hope this helps :)

Because r must be between -1.00 and +1.00 and the closer to either indicates a stronger relationship, the strongest must be -0.74. It is a strong negative correlation.

Any statistical association, whether causal or not, between two random variables or bivariate data is referred to in statistics as correlation or dependency. A statistical measure known as correlation expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical technique for describing straightforward connections without explicitly stating cause and consequence.

A relationship between two variables is said to have a positive correlation when both variables move in the same direction. Consequently, when one variable rises as the other rises, or when one variable falls while the other falls. The link between height and weight is a good example.

Mixed number is the combination of the whole number and the proper fraction. One is integer and other is fraction in a mixed number. When you multiply a mixed number by another mixed number the product is equal to the another mixed number. For exact same mixed number, when you multiply a mixed number by one  number the product is equal to the mixed number.

Mixed number is the combination of the whole number and the proper fraction. One is integer and other is fraction in a mixed number. As it is the combination of two types of number thus it is known as mixed number.

Mixed number are used to count the whole and part of a thing together.

For example five and a half of a thing can be written as,

\(5+\dfrac{1}{2} =5\dfrac{1}{2}\)

Now when a mixed number is multiplied by the another mixed number the product of both is a another mixed number.

For example let multiply 2 and a half with 3 and a half. The result is,

\(2\dfrac{3}{2} \times3\dfrac{3}{2} =\dfrac{7}{2} \times \dfrac{9}{2}\)

\(2\dfrac{3}{2} \times3\dfrac{3}{2} =\dfrac{63}{4}\)

\(2\dfrac{3}{2} \times3\dfrac{3}{2} =15\dfrac{3}{4}\)

Thus when you multiply a mixed number by another mixed number the product is equal to the another mixed number.

If the product should be equal to the given mixed number thus it need to be multiplied by the one. Thus when you multiply a mixed number by one  number the product is equal to the mixed number.

Answer: LM

Step-by-step explanation:

subtract and the use PEMDAS

Answer:

Let's denote the number of people in Team A as a, and the number of people in Team B as b. From the problem, we know that:

a/b = 3/4

Now, we also know that 4/5 of Team A and 24% (or 24/100 = 6/25) of Team B work full time. So, the number of people working full time from Team A is 4a/5 and from Team B is 6b/25.

The total number of people working for the company is a + b, and the total number of people working full time is 4a/5 + 6b/25.

We are asked to find the fraction of people working full time, which can be represented as:

(4a/5 + 6b/25) / (a + b)

Firstly, we need to have a common denominator for the fractions, so we can express 4a/5 as 20a/25:

\((20a/25 + 6b/25) / (a + b)\)

Simplifying, we can write this as:

\((20a + 6b) / (25(a + b))\)

Now, since we know a/b = 3/4, we can substitute a = 3b/4 in the above expression:

\((20*(3b/4) + 6b) / (25((3b/4) + b))\)

Simplifying the above, we get:

\((15b + 6b) / (25((3b/4) + b)) = 21b / 25b\)

So, the fraction of people working full time is 21/25.

Step-by-step explanation:

The price of an adult ticket is $20

The price of a child's ticket is $19

Let x represent the price of a child ticket

Let y represent the price of an adult ticket

Three adults and four children must pay 136

3y + 4x= 136.........equation 1

Two adults and three children must pay $97

2y + 3x= 97.........equation 2

From equation13 1

3y+4x= 136

3y= 136-4x

y= 136-4x/3

Substitute 136-4x/3 for y in equation 2

2(136-4x) + 3x= 97

272-8x/3 + 3x/1= 97

272-8x+9x/3= 97

cross multiply

272-8x+9x=291

collect the like terms

-8x+9x= 291-272

x= 19

Substitute 19 for x in equation 1

3y+4x= 136

3y + 4(19)= 136

3y+ 76= 136

3y= 136-76

3y=60

(i) tangent length is 64.99 m, (ii) 3359.77 m, (iii) 19.12 m, (iv) 126.08 m, (v) 3485.85 m, (vi) 20 m, (vii) 6, (viii) 12.94 m, 10 m, and 8.06 m, respectively, (ix) 0.65 m, (x) 0.52 m.

To calculate the values, we can use the following formulas:

(i) Tangent length:

Tangent length = (Radius of curve) × tan(Deflection angle/2)

Tangent length = 200 × tan(15°)

Tangent length = 200 × 0.2679

Tangent length = 53.58 m (rounded to 2 decimal places)

(ii) Chainage at the Point of Curve:

Chainage at the Point of Curve = Chainage at Point of Intersection + Tangent length

Chainage at the Point of Curve = 3276.78 m + 53.58 m

Chainage at the Point of Curve = 3359.36 m (rounded to 2 decimal places)

(iii) First subchord:

First subchord = Standard chord - Tangent length

First subchord = 20 m - 53.58 m

First subchord = -33.58 m (negative indicates a deflection angle greater than 90°)

(iv) Curve length:

Curve length = (Deflection angle/360°) × (2π × Radius of curve)

Curve length = (30°/360°) × (2π × 200)

Curve length = (1/12) × (2π × 200)

Curve length = 104.72 m (rounded to 2 decimal places)

(v) Chainage at the Point of Tangency:

Chainage at the Point of Tangency = Chainage at the Point of Curve + Curve length

Chainage at the Point of Tangency = 3359.36 m + 104.72 m

Chainage at the Point of Tangency = 3464.08 m (rounded to 2 decimal places)

(vi) Second subchord:

Second subchord = Standard chord - First subchord

Second subchord = 20 m - (-33.58 m)

Second subchord = 53.58 m

(vii) Number of Full chords:

Number of Full chords = Curve length / Standard chord

Number of Full chords = 104.72 m / 20 m

Number of Full chords = 5.236 (rounded to 3 decimal places)

Number of Full chords = 6 (rounded to the nearest whole number)

(viii) Chords due to first, second, and third subchord:

Chords due to first subchord = First subchord × (Number of Full chords - 1)

Chords due to first subchord = -33.58 m × (6 - 1)

Chords due to first subchord = -167.9 m (rounded to 1 decimal place)

Chords due to second subchord = Second subchord × 2

Chords due to second subchord = 53.58 m × 2

Chords due to second sub

chord = 107.16 m

Chords due to third subchord = Standard chord - First subchord - Second subchord

Chords due to third subchord = 20 m - (-33.58 m) - 53.58 m

Chords due to third subchord = 107.16 m

(ix) Midordinate:

Midordinate = Radius of curve - (Chords due to first subchord + Chords due to second subchord + Chords due to third subchord)

Midordinate = 200 m - (-167.9 m + 107.16 m + 107.16 m)

Midordinate = 63.7 m (rounded to 2 decimal places)

(x) External distance:

External distance = Radius of curve - Midordinate

External distance = 200 m - 63.7 m

External distance = 136.3 m (rounded to 2 decimal places)

Therefore, the values are as follows:

(i) Tangent length = 53.58 m

(ii) Chainage at the Point of Curve = 3359.36 m

(iii) First subchord = -33.58 m

(iv) Curve length = 104.72 m

(v) Chainage at the Point of Tangency = 3464.08 m

(vi) Second subchord = 53.58 m

(vii) Number of Full chords = 6

(viii) Chords due to first, second, and third subchord = -167.9 m, 107.16 m, 107.16 m

(ix) Midordinate = 63.7 m

(x) External distance = 136.3 m
