MODELING REAL LIFE You consider buying a phone from one of two cell phone carriers. The table shows the total costs
(in dollars) of the phone and service for different numbers of months at Carrier A. The total cost y (in dollars) of the phone
and x months of service at Carrier B is represented by the equation y = 55x + 300. Which carrier has the lower initial fee?
Answer:
Step-by-step explanation:
The carrier that has the lower initial fee is carrier B
How to determine which carrier has the lower initial fee?For carrier B, we have the following equation
y = 55x + 300
Set x = 0 to determine the initial fee
y = 55 x 0 + 300
Evaluate
y = 300 ---- the initial fee of carrier B
For carrier A, we have the following points on the table
(x, y) = (3, 500), (6, 650)
The slope of the points is calculated using
m = (y2 - y1)/(x2 - x1)
This gives
m = (650 - 500)/(6 - 3)
Evaluate
m = 50
Let the initial fee of carrier B y
So, we have the following points
(x, y) = (0, y), (6, 650)
The slope of the points is calculated using
m = (y2 - y1)/(x2 - x1)
This gives
m = (650 - y)/(6 - 0)
Evaluate
m = (650 - y)/6
Substitute m = 50 in m = (650 - y)/6
50 = (650 - y)/6
This gives
300 = 650 - y
Solve for y
y = 350
So, we have:
y = 300 ---- the initial fee of carrier B
y = 350 ---- the initial fee of carrier A
300 is less than 350
Hence, the carrier that has the lower initial fee is carrier B

Solution : Straight line question : y= 2x-3
Straight Line:
A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.
Slope:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line
1)Point (3,3) (4,5)
slope: (5-3)/(4-3) = 2/1 = 2
Y= mx+c
y -3 = 2(x-3)
y-3= 2x-6

1, .25 blank , -1.25, blank complete each arithmetic sequence
The complete arithmetic sequence is 1, .25, -0.5, -1.25, -2
How to complete the arithmetic sequence?The arithmetic sequence is given as:
1, .25, blank, -1.25, blank
Replace the blanks in the arithmetic sequence with x and y
So, we have:
1, .25, x, -1.25, y
An arithmetic sequence has a common difference (d)
The common difference is calculated using
d = T2 - T1
So, we have
d = 0.25 - 1
d = x - 0.25
d = y + 1.25
Substitute d = x - 0.25 in d = 0.25 - 1
x - 0.25 = 0.25 - 1
This gives
x = 0.25 + 0.25 - 1
Evaluate the sum
x = -0.5
Substitute d = 0.25 - 1 in d = y + 1.25
0.25 - 1 = y + 1.25
This gives
y = 0.25 - 1 - 1.25
Evaluate
y = -2
Hence, the complete arithmetic sequence is 1, .25, -0.5, -1.25, -2

Andy and his friend sam were walking along the road together. andy had a big bag of marbles. unfortunately the bottom of the bag split and all the marbles spilled out. poor andy! one third of the marbles rolled down the slope too quickly for andy to pick them up. one sixth of all the marbles disappeared into the rain-water drain. andy and sam picked up all they could but half of the marbles that remained nearby were picked up by other children who ran off with them. andy counted all the marbles he and sam had rescued. he gave one third of these to sam for helping him pick them up. andy put his remaining marbles into his pocket. there were 14 of them. how many marbles were there in andy's bag before the bottom split?
The total number of marbles that were there in Andy's bag before the bottom split are 84 marbles.
Let, the total number of marbles Andy have in the bad in beginning = x
One third of the marbles rolled down the slope too quickly for Andy to pick them up. So we can write,
Total number of marbles Andy have now = x - (x/3)
One sixth of all the marbles disappeared into the rain-water drain. So, So we can write,
Total number of marbles Andy have now = x - (x/3) - (x/6) = (x/2)
Half of the marbles that remained nearby were picked up by other children who ran off with them. So, we can write
Total number of marbles Andy have now = (x/2) - (x/4) = (x/4)
Andy gave one third of these to Sam for helping him pick them up. So,
Total number of marbles Andy have now = (x/4) - (x/12) = (x/6)
Now, we have given that Andy have 14 marbles in the end in his pocket. On comparing it with above equation, we get
(x/6) = 14
⇒ x = 84
The total number of marbles that were there in Andy's bag before the bottom split are 84 marbles.

What is the End behavior of the Polynomial?
The Factor Theorem states that a function with leading coefficient a and zeros x1, x2, x3,....,xn is defined by;
g(x) = a(x - x1)(x - x2).....(x - xn)
In the given table;
f(x) = 0 for x = -4 and 12. Thus, the zeros are x1 = -4 and x2 = 12
Then the definition is;
g(x) = a(x + 4)(x - 12)
g(x) = a(x² - 8x - 48)
The end behavior is the limit of g(x) as x goes to infinity, thus:
limₓ→ ∞ g(x) = limₓ→ ∞ax² = a * ∞
Since the leading coefficient a is negative, then;
a * ∞ = - ∞
Thus, the end behavior of g(x) is; As x→–∞, g(x)→–∞ and as x→∞, g(x)→–∞.

A set of 10 scores has ss = 90. if the scores are a sample, the sample variance is ____, and if the scores are a population, the population variance is ____.
If the scores are a sample, the sample variance is 10, and if the scores are a population, the population variance is 9.
A set of 10 scores has SS = 90.
The formula in getting the population variance is
σ² = SS / N
where SS is the sum of squared deviation and N is the number of population.
Therefore, the population variance is
σ² = 90 / 10
σ² = 9
The formula in getting the sample variance is
σ² = SS /( n - 1)
where SS is the sum of squared deviation and n is the number of samples.
Therefore, the sample variance is
σ² = 90/ (10 - 1)
σ² = 90 / 9
σ² = 10
Therefore, if the scores are a sample, the sample variance is 10, and if the scores are a population, the population variance is 9.
