Ayden is Buyingbagel for a family Gathering. Each bagel cost $2.00 Answer the question Regarding the relationship between the total cost and the number of bagels purchased. The independent variable represents the Total cost Number of bagels purchased $2 F(x)=2x
Answer:
$4
Step-by-step explanation:
Step one:
given data
Each bagel cost $2.00
Also, the cost function is given as
[tex]F(x)=2x[/tex]
Step two:
Required
The total cost of bagels purchased
From the cost function, we can see already that Ayden Bought 2 Bagel, hence if one bagel cost $2 then
[tex]F(x)=2(2)\\\\F(x)=4[/tex]
The two bagels will cost $4

О c

O d
20
Answer:
3Step-by-step explanation:
Given the function f(x) = (5x+1)/2
We are to find the inverse first as shown;
let y = f(x)
y = (5x+1)/2
Replace y with x
x = (5y+1)/2
Make y the subject of the formula;
2x = 5y+1
5y = 2x-1
y = (2x-1)/5
f^-1(x) = (2x-1)/5
f^-1(8) = 2(8)-1/5
f^-1(8) = 16-1/5
f^-1(8) = 15/5
f^-1(8) = 3
Hence the answer is 3

Find the sum of the first 8 terms of the following sequence. Round to the nearest
hundredth if necessary.
32,
-16,
8, ...
Answer:
63.75
Step-by-step explanation:
this is a geometric progression with a common ratio of -1/2
the formula for the sum of first n numbers is
Sn = (a1(1-r^n)) / 1 - r
so S8 = (32*(1 - 1/2^8)) / (1 - 1/2)
32*(255/256) / 0.5
Sn= 255 / 4 = 63.75
A mathematics teacher wanted to see the correlation between test scores and
homework. The homework grade (x) and test grade (y) are given in the accompanying
table. Write the linear regression equation that represents this set of data, rounding
all coefficients to the nearest hundredth. Using this equation, find the projected test
grade, to the nearest integer, for a student with a homework grade of 49.
The linear regression equation that represents this set of data is Y = -12.41 + 1.15x and the projected test grade for a student with a homework grade of 49 is 44 and this can be determined by using the generalized equation of regression.
Given :
A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table.The generalized regression equation is given below:
Y = a + bX --- (1)
where b is given by the formula:
[tex]\rm b = \dfrac{N\sum XY-\sum X \sum Y}{N\sum X^2-(\sum X)^2}[/tex]
Now, substitute the values of the known terms in the above formula in order to determine the value of 'b'.
b = 1.15
and the formula of a is given below:
[tex]\rm a = \dfrac{\sum Y - b \sum X}{N}[/tex]
Now, substitute the values of the known terms in the above formula in order to determine the value of 'a'.
a = -12.41
Now, substitute the values of a and b in the equation (1).
Y = -12.41 + 1.15x
Now, at x = 49 the value of Y becomes:
Y = -12.41 + 1.15(49)
Y = 43.94
Y [tex]\approx[/tex] 44

A 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance. which answer best describes how they fall? responses both balls hit the ground at the same time. both balls hit the ground at the same time. the 100 g ball hits the ground first. the 100 g ball hits the ground first. the 50 g ball hits the ground first.
When the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, B. both balls hit the ground at the same time.
How to illustrate the information?When an object moves through the air, air resistance acts as a force. When a body is moving through the air, this force works in the opposite direction. A frictional force is applied to the moving body by air resistance. Air resistance causes a body's speed to slow down as it moves.
Because air resistance slows down the motion of the falling object, it impacts acceleration during a fall to a lesser extent than gravity (g). The object's surface area and speed both influence how much it slows down.
Therefore, when the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, both balls hit the ground at the same time.

[ZA WARUDO] stops time and throws 200 knives at Jotaro Kujo. Then he adds one more and summons a ROAD ROLLER DA And smashes jotaro with it and it explodes. This subtracts 32 knives. How many knives did [ZA WARUDO] throw?
Answer:
169 knives
Step-by-step explanation:
What we know:
ZW threw 200 knives at Jotaro, then adds one more. This makes 201 knives, initially.
However, the RRD subtracts 32 from 201, making it 169 knives that ZW threw.
201 - 30 - 2 = 171 - 2 = 169 knives

Here, we want to calculate the distance between the submarine and the aircraft
From the question;
The aircraft is 200 m above the surface and the submarine is 55 m below ( this is same as an altitude of -55)
So the distance between the two will be;
200-(-55) = 255 m
Answer:

Explain why f(x) = x^2-x-6/x^2-9 is continuous at x = 2.
a. f is defined at x = 3
b. f is not defined at x = 2
c. f is defined at x = -3
d. f is defined at x = 2
The correct answer is option D. ([tex]f[/tex] is defined at [tex]x = 2[/tex])
The rational Function is continuous at a given value if its Denominator is not zero. In this exercise, we proceed to Factor the expression by check the value Denominator for each value of [tex]x[/tex].
[tex]f(x) = \frac{x^{2}-x-6}{x^{2}-9}[/tex]
[tex]f(x) = \frac{(x-3)\cdot (x+2)}{(x+3)\cdot (x-3)}[/tex]
As we can see, [tex]f[/tex] is not defined for [tex]x = -3[/tex] and [tex]x = 3[/tex]. Hence, we conclude that right answer is D.

You use a line of best fit set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.793. How confident can you be that your predicted value will be reasonable close to the actual value?
Answer:
Moderately confident
Step-by-step explanation:
Given that :
Correlation Coefficient = 0.793
The correlation Coefficient gives the strength of relationship between linear variables ranging from - 1 to 1.with values close to either - 1 or 1 depicting strong negative or positive correlation respectively, while values close to 0 signifies a weak correlation. Since the correlation Coefficient Given by the model is close to 1(0.793) one can be moderately confident that the value obtained from the model will be reasonably close to the actual value.
