The unit rate of orange could be found by Sara and Daniel by ratio to be $1.50

If Sara's mother bought 8 large oranges for $12.00

Sara may have thought of it like if $12 is for 8 oranges the how much is for 1

12 : 8 then X : 1

12/8 then x/1

12/8 = x/1

x = $1.50

Daniel would have taken this method, if 8 oranges costs $12 then 1 orange would cost ?

8 oranges : $12 then 1 orange : ?

8 : 12 = 1 : ?

8/12 = 1/?

8 * ? = 1 * 12

? = 12/8

? = $1.5

The probability of winning the minimum award is [tex]\frac{^4C_3 . ^{53}C_1}{^{57}C_4} \times \frac{1}{47}[/tex].

The Player chooses 4 numbers from white balls numbered 1 to 59 and

1 number from gold ball numbered 1 to 47

He has to choose 3 correct numbers out of 4 numbers in the white ball

and 1 number from the gold balls.

He can do in [tex]^4C_3 . ^{53}C_1[/tex] and 1 way respectively.

So, the probability can be given by;

Probability = probability of choosing white ball * probability of choosing red ball

Probability = [tex]\frac{^4C_3 . ^{53}C_1}{^{57}C_4} \times \frac{1}{47}[/tex]

Thus, the probability of winning the minimum award when players pick four different numbers from 1 to 59 and one number from 1 to 47 and a player wins a minimum award of $225 by correctly matching three numbers drawn from the white balls (1 through 59) and matching the number on the gold ball (1 through 47) is [tex]\frac{^4C_3 . ^{53}C_1}{^{57}C_4} \times \frac{1}{47}[/tex].

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.

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];

Step-by-step explanation:

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 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

Answer:

Question 1: We need to know whether Angles P and N are congruent or not.

Question 2: Cannot be proven congruent

Question 3: AAS Congruence Theorem

Question 4: ASA Congruence Postulate

Step-by-step explanation:

Background info: The information (congruence lines on sides and angles) is read counterclockwise (starting from the very left to right).

Question 1: In order to prove the triangles congruent with the AAS, we need two pairs of congruent angles and one pair of congruent sides. We still need one more pair of congruent angles. Since the triangle is read counterclockwise, the angle to the left of the current congruent angle given needs to be given to us. This is angles P and N.

Question 2: For this answer, the triangles cannot be proven congruent because we are only given three congruent angle pairs. This means that it should be the "AAA" Theorem, however, it doesn's exist due to the fact that the triangles could still be two different sizes despite the fact that the angles are the same. In order to prove this congruent, we would need info on congruent sides.

Question 3: Reading the triangle left to right, we see a congruent angle pair (A), another congruent angle pair (A), and a congruent side pair (S). Putting this together, we get AAS.

Question 4: Reading the triangle left to right, we see an angle pair (A), a side pair (S), and an angle pair (A). Putting this together, we get ASA.

Hope this helps! (No guarantees it's 100% correct)

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 =

= 2x² - 4x + 2 - 2 = 2x² - 4x
