For each goody bag we need 3.4 cookies

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

We are given that there are 17 cookies that will be divided equally among 5 goody bags.

17 cookies = 5 goody bags.

For each goody bag.

Thus,

17/5 = 3.4 cookies.

The materials travel faster on Belt One, considering the constants of the proportional relationships.

A proportional relationship is a linear function with intercept zero in which the output variable symbolized by y is given by the multiplication of the input variable symbolized by x and the constant of proportionality symbolized by k, according to the equation presented as follows:

y = kx

For each belt in this problem, the constant gives the velocity that the materials travel.

For Belt One, the relation is:

y = 157.1x.

Hence the velocity is of 157.1 inches per minute.

For Belt Two, the velocity is obtained as follows:

k = 125.6/2 = 62.8 inches per minute.

157.1 > 62.8, hence it travels faster on Belt One.

Answer: 15 cm

Step-by-step explanation:

just divide 60 by 4 and because a squar has 4 sides and that is it

Step-by-step explanation:

among other details this is the main thing about the standard form :

a polynomial in standard form is the sum of one or more terms; each term must be a monomial in standard form. also, the degrees of the terms should be decreasing as much as possible from left to right.

a monomial is the product of one or more factors: a constant coefficient and one factor for each variable in the expression. via exponent (e.g. 0) we control which variable is actually "showing", as any x⁰ = 1 and can therefore be omitted when writing as factor.

in other words :

e.g.

4x³ + 2x² + 5x + 1

2x + 3y + 7xy

are examples of the standard form.

in our case we have only x a variable. but we need to do all the squaring and multiplications and summing up to get the standard form.

that means

2(x - 1)² - 2 = ...

remember the priorities :

1. brackets

2. exponents

3. multiplications and divisions

4. additions and subtractions

2(x - 1)² - 2 = 2(x² - 2x + 1) - 2 =

The graph of the function f(x) = x³ and g(x) = (x - 3)³ are related to each other that the function g(x) is shifted right to 3 points.

Function

Basically, function is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Given,

Here we need to find how the graph of g(x)=(x-3)³ related to the graph of f(x) = x³.

Here we have the two equations of the function that are,

f(x) = x³

g(x) = (x - 3)³

By looking at the given functions, we have identified that f(x) be the parent function:

And it can be written as,

=> f(x) = x³

And the first transformation is applied as,

f(x) → f(x) - 3

Now, the function f(x)  will shift right side by 3 units

Therefore, the function f(x) = x³ and g(x) = (x - 3)³ are related to each other that the function g(x) is shifted right to 3 points.

The volume of the cuboid is 153000 [tex]cm^{3}[/tex];

What is the volume of the cuboid?

In general, the volume of a cuboid is equal to the area that it takes up in space. It is dependent upon the cuboid's three dimensions, or its length, breadth, and height. Due to the fact that all of a cuboid's faces are rectangular, the term "Solid Rectangle" is also referred to as a cuboid. All of the angles and the opposite faces of a cuboid in a rectangular cuboid are at right angles. A cuboid's volume is determined by the product of its length, breadth, and height. Cubic units are used to measure cuboids' volume.

The product of a cuboid's base area and height determines its volume. We can therefore write;

Cuboid volume equals base area times height [in cubic units].

The cuboid's base is shaped like a rectangle. As a result, a cuboid's base area is determined by multiplying its length by its breadth. Hence,

A cuboid's volume is equal to its length, width, and height in cubic units, or

A cuboid's volume is equal to l b h [in cubic units].

l = length, b = width, and h = height.

In the given question, we have;

Length = 30 cm;

Breadth = 60 cm;

Height = 85 cm;

And,

we know that:

The volume of the cuboid = lbh

The volume of the cuboid  = 30×60×85 [tex]cm^{3}[/tex]

The volume of the cuboid  = 1800 ×85 [tex]cm^{3}[/tex];

The volume of the cuboid  = 153000 [tex]cm^{3}[/tex];

Hence,

The Z-score for a GPA of 2.98 is 1.60345

A Z-score is a numerical value or measurement that explains the relationship between a value of data and the mean of a group of values. It will be calculated in terms of standard deviations from the mean.

The formula to calculate the Z -score is given by

                     Z - score =  [tex]\frac{( \bar{x} -\mu) }{\sigma}[/tex]    

Where  [tex]\bar {x}[/tex]  = test value

μ = mean and σ = standard deviation

Here we have

GPAS at CCCOnline are normally distributed with a mean of 2.05 and a standard deviation of 0.58

⇒ mean μ = 2.05

⇒ Standard deviation σ = 0.58  

And we need to find the z-score for a GPA of 2.98

⇒  [tex]\bar {x}[/tex] = 2.98

From above observations

Z - score =  [tex]\frac{( 2.98 -2.05) }{0.58}[/tex]  

= [tex]\frac{( 0.93) }{0.58}[/tex]

= 1.60345

The equation of the line passing through y = 3x-1 and (3,2) is y = 3x-7.

According to the question,

We have the following information:

y = 3x-1 and the point through which line is passing is (3,2)

We know that the slope of the given line (denoted by m) is 3.

Now, the following formula is used to find the equation of the line passing through a point:

y-y' = m(x-x')

In this case, we have x' = 3 and y' = 2.

y-2 = 3(x-3)

y-2 = 3x-9

Moving 2 from the left hand side to the right hand side will result in the change of the sign from minus to plus:

y = 3x-9+2

y = 3x-7

Hence, the equation of the line passing through y = 3x-1 and (3,2) is y = 3x-7.

The earnings per hour be after working for 15 years is $11.4.

From the given table (2, 6.85), (4, 7.55), (6, 8.25).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

1) Now, put (x1, y1)=(2, 6.85) and (x2, y2)=(4, 7.55) in slope formula, we get

m=(7.55-6.85)/(4-2)

= 0.7/2

= 0.35

Substitute m=0.35 and (x, y)=(2, 6.85) in y=mx+c, we get

6.85=0.35(2)+c

⇒ 6.85=0.7+c

⇒ c=6.85-0.7

⇒ c=6.15

Now, equation is y=0.35x+6.15

2). Put x=15 in the obtained equation, we get

y=0.35×15+6.15

⇒y=$11.4

3). Put y=9.65 in the obtained equation, we get

9.65=0.35x+6.15

⇒0.35x=9.65-6.15

⇒0.35x=3.5

⇒x=3.5/0.35

⇒x=10 years

Therefore, the earnings per hour be after working for 15 years is $11.4.
