Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.

Step-by-step explanation:

Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)

The value of x is 1/5.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3/5 (x − 7/10)= −3 1/4

Now, Solving for x

3/5 ( x- 7/10 )= 13/4

x- 7/10 = -13/4 x 5/3

x- 7/10 = -65 /12

x= -65/12 + 7/10

x= 24/ 120

x= 1/5

hence, the value of x is 1/5.

The cost of having photos taken includes a sitting fee and $12 for each portrait. The cost of 3, 6, and 9 photos respectively is $51, $87, and $123. What is the sitting fee? Use units in your answer and round answer to the hundredths place, for example $2.35
plz help

Answers

Answer:

The sitting fee is 15 dollars

Step-by-step explanation:

1 - 12 x 3 = 36

2 - 51 - 36 = 15

3 - 12 x 6 = 72

4 - 87 - 72 = 15

Answer:

$15.00

Step-by-step explanation:

cost of photos = sitting fee + $12 per photo

Let the number of photos = x

Let the sitting fee = s

cost of photos = s + 12x

cost of 3 photos = $51

s + 12(3) = 51

s + 36 = 51

s = 15

Answer: The sitting fee is $15.00

Which ordered pair would form a proportional relationship with the point graphed below?

Answers

Answer:

-10, 20 because -20, 40 divided by 2 = -10, 20

The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:

(15, -30).

What is a proportional relationship?

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

The constant for this problem is given as follows:

k = 40/-20

k = -2.

Hence the equation is:

y = -2x.

When x = 15, the numeric value of the equation is given as follows:

y = -2(15)

y = -30.

Hence the point is:

(15, -30).

This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.
