Hello!
The approximate predicted number of stamps she collected in the 25th month is 990.
Step-by-step explanation:
The ordered pairs are as follows:
( 1, 30), ( 2, 70), ( 3, 110), ( 4, 150), and ( 5, 190).
The pattern visible is that each month the value increases by 40 from each previous month.
The equation you would have to do in order to see how many stamps she collected is:
\(30\) + \(40\) × \(24=30\) + \(960=990\)

50 POINTS The amount of laps remaining, y, in a swimmer's race after x minutes can be represented by the graph shown.
coordinate grid with the x axis labeled time in minutes and the y axis labeled number of laps remaining with a line from 0 comma 26 and 13 comma 0
Determine the slope of the line and explain its meaning in terms of the real-world scenario.
The slope of the line is 13, which means that the swimmer will finish the race after 13 minutes.
The slope of the line is 26, which means that the swimmer must complete 26 laps in the race.
The slope of the line is negative one half, which means that the swimmer completes a lap in one half of a minute.
The slope of the line is −2, which means that the swimmer will complete 2 laps every minute.
Answers
The slope of the line is -4 which represents the swimmer will complete 4 laps per minute.
Here, we have,
In real world scenario it means how many laps they can complete per minute.
Let us consider the coordinate on the y-axis and the x-axis be ,
( x₁ , y₁ ) = ( 0, 24 )
( x₂ , y₂ ) = ( 6, 0)
The slope of a line represents the rate of change between two variables.
Here, the slope of the line represents the rate at which the number of laps remaining changes with respect to time.
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
= ( 0 - 24 ) / ( 6 - 0 )
= -4
Since the slope of the line is -4, this means that for every one minute that passes.
The swimmer completes 4 laps since the slope is negative, the number of laps remaining decreases as time increases.
So in this scenario, the slope of the line tells us that the swimmer is completing laps at a rate of 4 laps per minute.
And that they will finish the race after 6 minutes when they have completed all 24 laps.
Therefore, slope of line is -4 represents the swimmer's lap completion rate which means swimmer will complete 4 laps every minute.

A graph shows the horizontal axis numbered 15 to 54. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 24, a downward trend from 24 to 27, an upward trend from 27 to 30, a downward trend from 30 to 39, an upward trend from 39 to 45, a downward trend from 45 to 48, then an upward trend from 48 to 51.
Answers
To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.
Looking at the histograms described:
The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.
The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.
The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.
The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.
Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

For the polynomial function f(x) = x3 - 7x2 + 10x , what is the average rate of change over the interval [2 , 4]
Answers
Answer:
The average rate of change of the given function over the interval [2, 4] is -4.
Step-by-step explanation:
To find the average rate of change of a function f(x) over the interval [a, b], we should use the formula:
\(\boxed{\textsf{Average rate of change}=\dfrac{f(b)-f(a)}{b-a}}\)
Given function:
\(f(x) = x^3 - 7x^2 + 10x\)
To find the average rate of change of the given function over the interval [2, 4], we need to first find the values of f(2) and f(4).
\(\begin{aligned}f(2) &= (2)^3 - 7(2)^2 + 10(2)\\&= 8 - 7(4) + 10(2)\\&= 8 - 28 + 20\\&= -20 + 20\\&= 0\end{aligned}\)
\(\begin{aligned}f(4) &= (4)^3 - 7(4)^2 + 10(4)\\&= 64 - 7(16) + 10(4)\\&= 64 - 112 + 40\\&= -48+ 40\\&= -8\end{aligned}\)
Substitute the values into the formula for the average rate of change over the interval [2, 4]:
\(\textsf{Average rate of change} = \dfrac{f(4) - f(2)}{4 - 2} = \dfrac{-8-0}{4-2}=\dfrac{-8}{2}=-4\)
Therefore, the average rate of change of the given function over the interval [2, 4] is -4.

If the circumference of a circle made by a wire is 176cm later the wire is cut and made a rectangle wiith breadth 8cm. Find the length of the rectangle.
Answers
Answer:
The length of the rectangle is 80 cm.
What is circumference ?
Circumference is the distance around the edge of a circle. It is the total length of the boundary of a circle. In other words, it is the perimeter of the circle.
\(C=2\pi r\)
where r is the radius of the circle
Step-by-step explanation:
Let's start by using the given information about the wire and the circle. The circumference of a circle is given by the formula:
C=2πr
where C is the circumference and r is the radius of the circle.
We are given that the circumference of the circle made by the wire is 176 cm, so we can write:
176 = 2πr
Simplifying this equation, we get:
r = 88/π
Now, when the wire is cut and made into a rectangle, the length of the wire is equal to the perimeter of the rectangle. The perimeter of a rectangle is given by the formula:
P = 2(l + b)
where P is the perimeter, l is the length, and b is the breadth of the rectangle.
We are given that the breadth of the rectangle is 8 cm, so we can write:
P = 2(l + 8)
But we also know that the length of the wire is equal to the circumference of the circle, which we found to be 176 cm. So we can write:
P = 176
Substituting this into the previous equation, we get:
176 = 2(l + 8)
Simplifying this equation, we get:
l + 8 = 88
l = 80
Therefore, the length of the rectangle is 80 cm.

if x is a continuous random variable with the uniform distribution u(5.5,20.5), what is p(x<8)?
Answers
The correct value of p(x<8) is 1.875.
Define probabilityTo determine how probable something is gonna occur, use probability. It is a number between 0 and 1, where 0 denotes the absence of a possibility and 1 denotes the existence of one. By dividing the number of favorable outcomes by the entire number of potential possibilities, the probability of an occurrence is determined.
To find the probability that is greater than 8, we need to integrate this probability density function from 5.5 to 20.5:
P(X < 8) = ∫[5.5,20.5] f(x) dx
= ∫[5.5,20.5] (1/8) dx
= [x/8] from 5.5 to 20.5
= (20.5/8) - (5.5/8)
= 15/8
= 1.875.
Therefore, the correct probability is 1.875.

Find equation of the line that passes through points A and B

Answer:
y = 2x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = A (1, 7 ) and (x₂, y₂ ) = B (- 3, - 1 )
m = \(\frac{-1-7}{-3-1}\) = \(\frac{-8}{-4}\) = 2 , then
y = 2x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (1, 7 )

The ratio is simply the relation between two groups of things. For example you have 1/3 cups of water for every cup of flour. As we can see, when we add just one cup of flour, the amount of water needed increases by 1/3. this means that the very minimum of water needed is 1/3. (since the ratio must be simple) This means that it takes 3 cups of flour to make a whole cup of water. this also means that in relation to the 1/3 cup of water, 1 cup of flour is needed. this means the ratio is 1 to 1/3 because for every cup of flour, 1/3 cup of water is needed.
