Answer:
See Explanations
Step-by-step explanation:
The steps in the question isn't clear enough, however the question is answerable.
From the question, we understand that one model shows that:
200 is 10 times 20
While the second model shows that
200 is 10 times 2
The first model that says
200 = 10 times 20 makes sense.
This is so, because 200 = 20 * 100
While the other model which says
200 = 10 * 2 is nonsense.
This is so because, 200 ≠ 10 * 2

What does the Rational Root Theorem and Descartes' Rule of Signs indicate about the zeros of a polynomial function?
Answer:
"Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients."

Mary, John, and Stacy were paid $360 for working around , the house in a ratio of 3:6:9. How much more did Stacy make than John?
Answer:
$60
Step-by-step explanation:
Let the work done by Mary, John and Stacy be 3x,6x and 9x.
ATQ,
3x+6x+9x=360
18x = 360
x = 20
Mary's amount = 3x = 3(20) = $60
John's amount = 6x = 6(20) = $120
Stacy amount = 9x = 9(20) = $180
Difference in amont of Stacy and John = $180-$120 = $60
Hence, Stacy make $60 more than John's amount.

In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept:
Sale No Sale Row Total
Aggressive 255 325 580
Passive 472 108 580
Column Total 727 433 1160
Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa-passive approach, S-sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on.
A) Compute P(S), P(S | A), and P(S | Pa).
B) Are the events S-sale and Pa-passive approach independent? Explain.
A. Yes. P(S) P(S | Pa).
B. Yes. The two events can occur together.
C. No. The two events cannot occur together.
D. No. P(S)-P(s i Pa).
C) Compute P(A and S) and P(Pa and S).
D) Compute P(N) and P(N/A).
E) Compute P(A or S).

Complete the chart.
Answer:
1. L || m - Given in the question
2. ∠ 1 ≅ ∠ 3 - Since L || m, we can see in the image that ∠1 is corresponding to ∠3 since corresponding angles are the angles which occupy the same relative position at each intersection where a straight line crosses two others
3. ∠1 ≅ ∠2 - From the image, we can see that ∠1 is vertically opposite to ∠2, Hence ∠1 ≅ ∠2
4. ∠2 ≅ ∠3 - From the image, we can see that ∠2 and ∠3 are alternate angles, since alternate angles are angles that are in opposite positions relative to a transversal intersecting two lines.

A round garden has a circumference of 15.7 feet. Calculate the area of
the garden
Answer:
The area of a circle with circumference 15.7 is 19.62
Step-by-step explanation:
If this helped May I have brainliest Im trying to rank up.
Have a great day!
The area of the garden is 19.64 feet²
The garden has the shape of a circle.
The area of a circle = πr²
Where:
π= pi = 22/7
r = radius
In order to determine the area of the garden, the radius has to be determined first. The radius would be determined from the circumference of the circle.
Circumference of the circle = 2πr
15.7 = 2 x (22/7) x r
r = 15.7 ÷ ( 2 x 22/7)
r = 2.50 feet
Area of the garden = (22/7) x (2.5²) = 19.64 feet²
Please find attached an image of a circle.

Step-by-step explanation:
can you write an equivalent fraction for 5/9 and 1/10 using the least common denominator?
Answer: Yes
Step-by-step explanation:
Rewriting input as fractions if necessary:
5/9, 1/10
For the denominators (9, 10) the least common multiple (LCM) is 90.
LCM(9, 10)
Therefore, the least common denominator (LCD) is 90.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
5/9 = 5/9 × 10/10 = 50/90
1/10 = 1/10 × 9/9 = 9/90
#1.) What is the slope between point C and Point D? *Please Show All Work*
#2.) What is the equation of the line (Slope-Intercept Form: y = mx + b) that represents the climb from Point C to Point D? *Please Show All Work*
#3.) What is the domain and range the C to D part of the roller coaster?
Let's see what to do buddy....
_________________________________
1) Go...
We have the following equation for finding the slope of the line by using two points :
[tex]slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]
Where a and b are the points which the line through them.
We have points C and D here ,
So :
[tex]slope = m = \frac{y(d) - y(c)}{x(d) - x(c)} \\ [/tex]
D = ( 7 , 12 ) and C = ( 0 , 0 )
Now just need to put the coordinates in the above equation :
[tex]slope = m = \frac{12 - 0}{7 - 0} = \frac{12}{7} \\ [/tex]
_________________________________
2) Go...
We have the following equation to find the point-slope form of the linear functions :
[tex]y - y(o) =(slope) \times ( \: x - x(o) \: ) \\ [/tex]
Where o is one of the given points.
So we must choose one of the points ,
I choose : D = ( 7 , 12 )
Then we have :
[tex]y - 12 = \frac{12}{7}(x - 7) \\ [/tex]
It's point-slope form, so we need to simplifies it to find slope-intercept form.
Look:
[tex]y - 12 = \frac{12}{7}x - 12 \\ [/tex]
Both sides plus 12
[tex]y = \frac{12}{7}x \\ [/tex]
Now we have the slope-intercept form of the CD line.

3) Go...
Domain = [ 0 , 7 ]
Range = [ 0 , 12 ]

-cup serving. What is the unit rate for calories per cup? How many calories are there in of the cereal?
Answer:
112 calories per cup
Step-by-step explanation:
Let x = unit rate for calories per cup,
Then (3/4)*x = 84
and x = 84*(4/3) = 112 calories per cup
Answer:
1 cup = 128 calories
Step-by-step explanation:
you simply have to reverse the fraction and multiply it by that. 96×[tex]\frac{4}{3}[/tex]=128
