Ana has 3 fewer pots than she has the number of flowers.
What are some alternative names for arithmetic operations?Additions have an alternative name which is sum. Multiplication can also be called as the product, Subtraction can be called the difference and division can be called as the ratio.
To Obtain the number of fewer pots Ana has for flowers is the same as the difference between number of seeds and pots.
Number of seeds she has is 7 and the number of pots she has is 4.
∴ The number of fewer pots Ana has is ,
= (7-4) pots.
= 3 pots.
So, Ana has 3 fewer pots or Ana has 3 more seeds than the number of pots she has.

Write the statement "the sum of a number and 17.3 is at least −2.8" as an inequality.
−2.8 + b > 17.3
b + 17.3 ≥ −2.8
b + 17.3 ≤ −2.8
−2.8 + b < 17.3
The linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is b + 17.3 ≥ - 2.8 which is option B
We are given that the sum of a number and 17.3 is at least −2.8 and we have to form a linear inequality from the information provided
Let the number be b
so, the sum of two numbers would be
b + 17.3
It is given that the sum should be at least - 2.8
this means the sum is either equal to - 2.8 or sum is more than -2.8
So, the linear inequality equation comes to be
b + 17.3 ≥ - 2.8
Hence, the linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is b + 17.3 ≥ - 2.8 which is option B

Paul had 84 fliers to post around town. Last week he posted 1/6 of them. This week, he posted 4/7 of the remaining fliers. How many fliers has he still not posted?
The number of fliers that he has not posted is 8
What is proportion?Proportion can be defined as the mathematical comparison of two elements or numbers.
From the information given, we have that;
Total number of fliers is 84First week, 1/6 of the floors were postedThis week, 4/7 of the remaining were posted.To determine the number of fliers remaining, we have that;
Remaining fliers for the First week
= 84 × 1/6
Multiply and find the quotient
= 14 fliers
Fliers remaining after the last week
= 14 × 4/7
Multiply and find the quotient
= 56/7
= 8 fliers
Thus, the number of fliers the he has not posted is 8

A new observed data point is included in set of bivariate data. You find that
the slope of the new regression line has changed from 1.7 to 1.1, and the
correlation coefficient only changed from +.60 to +.61. This new data point is
probably a (an):
A. predicted (y) value.
B. residual.
C. influential point.
D. outlier.
4
SUBMIT
New data point is residual.
When a data point is added or removed from the whole dataset, it might cause a significant change in the regression equation by either changing the slope or the relationship coefficient existing between the variables.
An influential point is one that changes the relationship existing between the dependent and the independent variables significantly in either direction.
Since the new observed data point decreases the slope of the regression line but increases the correlation coefficient existing between the independent and the dependent variable, we can probably say that the new data point is an influential point.
Thus, Option B. is correct.

the function f(x)=(4x-8)^2 is the image of g(x)=x^2 after a set of transformations have occurred. which of the following describes the transformation that occurred to g(x)
The transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units
How to describe the transformation that occurred to g(x)?The equation of the functions are given as
f(x)= (4x - 8)^2
g(x) = x^2
Start by stretching the function g(x) horizontally by a scale factor of 4
This is represented as
g'(x) = g(4x)
So, we have
g(4x) = (4x)^2
This gives
g'(x) = (4x)^2
Next, we translate the function down by 8 units
This is represented as
f(x) = g'(x - 8)
So, we have
f(x) = (4x - 8)^2
Hence, the transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units

The length of LN in units is 64 units
How to determine the length of the line LNThe complete question is added as an attachment
From the question, we have the following parameters
LM = 10x + 8
MN = 5x - 4
LN = 12x + 6
The above means that
LN = LM + MN
So, we have
10x + 8 + 5x -4 = 12x + 16
Evaluate the like terms
So, we have
15x +4 = 12x + 16
Collect the like terms
So, we have
15x - 12x = 16 - 4
Evaluate the like terms
So, we have
3x = 12
Divide both sides by 3
x = 4
Next, we substitute x into LN = 12x + 16
So, we have
LN = 12(4) + 16
Evaluate
LN = 64
Hence, the length of LN in units is 64 units

What is the missing information?The graphs for which we choose the one which is not a function are missing, and are given at the end of the answer.
When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.
For this problem, we have that:
The circled graphed has vertically aligned points, that is, values of x inside the circle are mapped to multiple values of y, hence the graph is not a function.The other two graphs have no vertically aligned points, meaning that each value of x is mapped to only one value of y, hence they are functions.Hence the circled graph given at the end of the answer is not a function of x.

Between 10 pm and 7:36 am, the water level in a swimming pool decreased by 8/25 in. What is the constant rate
Answer:
he waters level dropped inch each hour
Step-by-step explanation:
- Between 10 P.M. and 7:45 A.M., the water level in a swimming pool
decreased by 13/16 inch
- Assuming that the water level decreased at a constant rate
- We need to find the drop each hour that means the unit rate of
decreased of the level of the water
- At first lets hind how many hours between 10 P.M. and 7:45 A.M.
∵ Between 10 P.M. and mid-night 2 hours
∵ Between mid-night and 7:45 A.M. 7 hours and 45 minutes
- Lets change 7 hours and 45 minutes to hours
∵ 1 hour = 60 minutes
∴ 45 minutes = 45 ÷ 60 = hours
∴ 7 hours and 45 minutes = hours
∴ The total hours between 10 P.M. and 7:45 A.M. = 2 + hours
∴ The total hours between 10 P.M. and 7:45 A.M. =
∵ The unit rate of decreased = The decreased level ÷ total hours
∵ The decreased level is inche
∵ The total hours = hours
- Lets change the mixed number to improper fraction
∵ =
∴ =
∵ The unit rate of decreased = ÷
- To solve the division of 2 fractions change the division sign to
multiplication sign and reciprocal the fraction after the division sign
∴ The unit rate of decreases = ×
∴ The unit rate of decreases = inch per hour
The water level dropped inch each hour
Answer:
1/30 inch per hour
Step-by-step explanation:
The time passed was 9 hours and 36 minutes, which is the same as 9.6 hours.

How to find the procedure error associated to a composition of functions
In this question we find two functions, with which we should perform an operation known as composition. Composition consists in substituting the input of a function by the other function. The operation is defined by the following expression:
f ° g (x) = f [g (x)]
Herein we must determine the mistake done by the student on the composition. If we know that f(x) = (3 · x - 7) / 4, g(x) = 2 · x - 1 and x = 0, then the value of g(f (0)) is:
g ° f (x) = g (f (x))
g ° f (x) = 2 · [(3 · x - 7) / 4] - 1
g ° f (x) = (3 · x - 7) / 2 - 1
