In the Trendline option window (curve fitting), the Set Intercept value is set to zero. What does this mean
Answer:
the data is modeled as a proportion
Step-by-step explanation:
When the trendline is chosen to be linear, the intercept value can be computed from the data, or it can be set to some value of your choosing. When it is set to zero, the data is approximated by a line that goes through the origin. That is, the model is of a proportional relationship.

Are the following fractions equivalent? Explain.
15/60 = 3/4
Answer:
No
Step-by-step explanation:
is 15/60 = 3/4?
Find the lowest term of 15/60.
The LCD of 15 and 60 is 15 so......
15 ÷ 15
— —
60 ÷ 15
= 1/4 (the lowest term of 15/60)
Since 1/4 is not equal to 3/4
Then 15/60 is not equivalent to 3/4.
Hope it helps.

A regression can take several forms such as linear models and quadratic models
The linear regression equation is: [tex]y = 7.35x + 557.1[/tex] and the quadratic regression equation is [tex]y = -1.196x^2 +21.707 x+523.6[/tex]
How to determine the regression equationsThe data set is given as:
x 2 4 6 8 10
y 567 580 616 625 618
Next, we make use of a graphing calculator to determine the regression equations
From the graphing calculator, we have the following calculation summary
Sum of X = 30Sum of Y = 3006Mean X = 6Mean Y = 601.2Sum of squares (SSX) = 40Sum of products (SP) = 294So, the linear regression equation is:
[tex]y = 7.35x + 557.1[/tex]
And the quadratic regression equation is:

Solve: 3x + 2y = 11 and 6x - 2y = 25.
Answer:
x = 4, y = -0.5
or (4,-0.5)
Step-by-step explanation:
Given:
3x + 2y = 11. . . (i)6x - 2y = 25. . . . (ii)Solution:
Adding equations (i) and (ii):
==> (3x + 2y) + (6x - 2y) = 11 + 25
2y gets cancelled:
==> 9x = 36
dividing the equation by 4:
==> x = 4
Substituting 4 for x in equation (i):
==> 3(4) + 2y = 11
==> 12 + 2y = 11
subtracting 12 from both sides:
==> 2y = 11 - 12
==> 2y = -1
dividing both sides by 2:
==> y = -1/2
==> y = -0.5
A bag contains sixty marbles. Adam takes 18 of them. The rest are shared equally between Oscar, Priya and Daisy. How many marbles does Daisy get?
Answer:
14
Step-by-step explanation:
Take away the marbles that adam has
60-18 = 42
There are 42 marbles to divide between Oscar, Priya and Daisy.
Divide 42 by 3
42/3 = 14
Daisy gets 14 marbles
Daisy gets 14 marbles
How to determine the amount Daisy got?The number of marbles in the bag is:
Marbles = 60
When Adam took 18 marbles, the remaining number of marble is:
Marbles = 60 - 18
Marbles = 42
When the remaining marbles are shared by Oscar, Priya and Daisy.
The amount by Daisy is:
Daisy = 42/3
Daisy = 14
Hence, Daisy gets 14 marbles

14 students have volunteered for a committee. Eight of them are seniors and six of them are juniors. (a) How many ways are there to select a committee of 5 students
======================================================
Explanation:
We have five slots to fill, which I'll label A through E.
There are,
14 choices for slot A13 choices for slot B12 choices for slot C11 choices for slot D10 choices for slot EEach time we fill up a slot, we count down by 1.
This gives 14*13*12*11*10 = 240,240 different permutations. If order mattered, then this would be the answer.
However, order doesn't matter on a committee without rankings. Each member has the same rank as any other.
Within any group of 5 people, there are 5! = 5*4*3*2*1 = 120 ways to arrange them. This means we divide that 240,240 figure by 120 to find the number of combinations.
There are (240,240)/(120) = 2002 different combinations.
---------------------------------------
Here's how we could have done the problem using the nCr combination formula.
Plug in n = 14 and r = 5.
n C r = (n!)/(r!(n-r)!)
14 C 5 = (14!)/(5!*(14-5)!)
14 C 5 = (14!)/(5!*9!)
14 C 5 = (14*13*12*11*10*9!)/(5!*9!)
14 C 5 = (14*13*12*11*10)/(5!)
14 C 5 = (14*13*12*11*10)/(5*4*3*2*1)
14 C 5 = (240240)/(120)
14 C 5 = 2002
Despite booming new car sales with their cha-ching
sounds, the average age of vehicles on roads is not
going down. The bar graph shows the average price of
new cars in Country A and the average age of cars o
roads for two selected years. In 2014, the average price
of a new car was $37,600. For the period shown, new-
car prices increased by approximately $1250 per year.
If this trend continues, how many years after 2014 will
the price of a new car average $47,600? In which year
will this occur?
How many Years after 2014 will the average price of new cars average $47,00?
I provided a Picture for the graph! Thanks a ton!
Answer to the 1st question: 8 years
Answer to the 2nd question: The year 2022
=======================================================
Further explanation:
x = number of years after 2008
y = average price of a new car
The prices are going up by $1250 per year on average. This is the slope because the slope is the rate of change. So m = 1250.
The y intercept is b = 30100 as this is the price in 2008.
This leads us to go from y = mx+b to y = 1250x+30100
Plug in x = 0 and you should get y = 30100.
Also, plugging x = 6 into the equation leads to y = 37600 to help confirm things.
-----------------
Next, we plug in y = 47600 and solve for x.
y = 1250x+30100
47600 = 1250x+30100
47600-30100 = 1250x
17500 = 1250x
1250x = 17500
x = 17500/1250
x = 14
This means 14 years after the year 2008 is when the average new car price will be $47,600.
2008+14 = 2022
2022-2014 = 8
Therefore, 8 years after 2014 (aka the the year 2022) is when the new car average price will be $47,600.

Answer:
^3sqrt(-27), ^3sqrt(-8), 0, ^3sqrt(8), ^3sqrt(27), sqrt(10), 6, 8
Step-by-step explanation:
You just need to convert these to decimals to figure it out.
In our case
^3sqrt(-27) = -3
^3sqrt(-8) = -2
^3sqrt(8) = 2
^3sqrt(27) = 3
sqrt(10) = 3.16
So...
-3, -2, 0, 2, 3, 3.16, 6, 8
