Step-by-step explanation:
a grocery store wants to examine the relationship between the sales amounts each day at two different locations, store a and store b. the sales amount each day, in dollars, was recorded for 10 days at each store. the least-squares regression line is yˆ
The mean of the 10 sales amounts for store A is $40,000
The least-squares regression line is
y=-3000+1.2x
where
x represents the sales amounts each day at store A
y represents the sales amounts each day at store B
we have
y=$45,000
substitute the value of y in the linear equation and solve for x
45000=-3000+1.2x
1.2x=48000
x=40000
therefore
The mean of the 10 sales amounts for store A is $40,000

what is the rate of. change for this ANd as a function
The rate of change of the function shown in the graph is $0.5 per minute.
What is rate of change?
The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time. When discussing momentum, the term "rate of change" is frequently used. It is typically defined as the ratio of a change in one variable to a matching change in another; visually, the rate of change is represented by the slope of a line. The Greek letter delta (Δ) is usually come in use to represent the ROC.
As shown in the graph,
The x-axis represents the minute and y-axis represents the cost.
and the cost is function of time.
For each 10 minute the cost increased $5
So, the cost is changing at a rate of $5 per 10 minute
$5 = 10 minutes
diving both side with 10
$0.5 = 1 minute
Therefore, the rate of change of the function shown in the graph is $0.5 per minute.

The value of f(–10) = 82The graph of the function is a parabola.The graph contains the point (20, –8).How to determine the true statements about this function and its graph?In Mathematics, the graph of any quadratic function or equation always forms a parabola because it is a u-shaped curve. For the given quadratic function, the graph is a upward parabola because the coefficient of x² is positive i.e when the value of "a" is greater than zero.
Next, we would determine the statements about the quadratic function and its graph that are true:
At point (-10, 82), we have:
f(x) = 1/5 x² – 5x + 12
f(x) = x²/5 – 5x + 12
f(-10) = -10²/5 – 5(-10) + 12
f(-10) = 82
At point (20, -8), we have:
f(x) = 1/5 x² – 5x + 12
f(x) = x²/5 – 5x + 12
f(20) = 20²/5 – 5(20) + 12
f(20) = -8

A mathematical statement indicating an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
Divide both sides of the inequality 2|x+1/3|3 to make it simpler:|x+1/3| < 3/2.
Consider the center of the group of numbers that fulfill 2|x+1/3|3 to be x = -1/3.
The maximum value of this set is obtained by adding 3/2 to this -1/3:
-1/3 + 3/2, or -2/6 + 9/6, or 7/6.
The bottom limit of this solution set is obtained by subtracting 3/2 from this and then -1/3:

The given expression is
(4+5i) / (2-4i)
Here we have to divide the given complex number
First multiply both numerator and denominator by 2+4i
(4+5i) / (2-4i) × (2+4i) / (2+4i)
= [tex]\frac{(4+5i)(2+4i)}{(2-4i)(2+4i)}[/tex]
Multiply the terms in the numerator and denominator.

= (-12+26i) / 20
= (-12/20) + (26/20)i
Divide both numerator and denominator by common terms

what is -10+3x>-16 inequality notation
The Inequality notation of the given equation 10+3x>-16 is x > -2
What is Inequality notation?
A mathematical statement known as an inequality expresses the relationship between two quantities while indicating that they are not completely equal. The four symbols used to represent inequality are. ≥, >,<, and ≤.
Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare the two values in inequality. Less than (or less than and equal to), greater than (and greater than or equal to), and also not equal to signs are used in place of the equal sign.
Consider the above equation.
-10 +3x > -16
Add 10 on both sides.
= -10+3x+10> -16+10
= 3x> -6
Divide by 3 to equation into both sides.

The value of the variable x is 2 and length of the segment AB = 25 and length of segment BC is 14.
What is segment addition postulate?If a Line segment AC is given in a plane and B is some point between the points A and C on the line segment AC. Then two segments of the line segment ac are formed that are AB and BC. and length of AC is equal to the sum of lengths of AB and BC.
Then AC = AB +BC
Given that B is point on the line segment AC
Length of AB line = 9x+7
Length of BC = -3x +20
Length of AC = 39
Using segment addition postulate,
we have AC = AB +BC
⇒ 39 = 9x+7 + (-3x) +20
⇒ 39 = 9x -3x +7+20
⇒39 = 6x +27

a. What is the value of x?
b. What would be the measure of < 2?
Then find the measure of <3.
Using the vertical angle image we get the following answers:
a) x = 18, b) ∠2 = 68°, c) ∠3 = 112°Given the equations are:
42 = 4x-4 and 24 = x+50.
According to vertical angles theorem, when two lines intersect the opposite angles are equal and adjacent angles are supplementary.
we know that,
∠2 = 4x-4 and ∠4 = x+50
a)To Find the value of x:
4x - 4 = x + 50
4x - x = 50 + 4
3x = 54
x = 54/3
x = 18
b) To Find the measure of ∠2:
∠2 = 4×18 - 4 = 72 - 4
= 68
c) Angles 2 and 3 are supplementary so their sum is 180°.
∠2 + ∠3 = 180
68 + ∠3 = 180
∠3 = 180 - 68
∠3 = 112°
Hence we get the required angles.

Q10. Farmer John's apples were eaten by wasps, others were rotten and the rest were quality apples in the ratio 4: 10: 20 respectively. 20 apples had been eaten by wasps. a) How many rotten apples were there?
If wasps had eaten 20 apples then, 50 rotten apples were there and the rest of the apples were quality apples in the ratio of 4: 10: 20 respectively.
This is a problem from simple mathematical equations. We can solve this problem by following a few steps.
Let's consider x as the highest common factor of apples eaten by wasps, rotten and quality apples.
So, the number of apples eaten by wasps is, 4 × x = 4x
The number of rotten apples is, 10 × x = 10x
The number of quality apples is, 20 × x = 20x
As, we all know HCF of the numbers × ratio of numbers = The numbers
So, 4x = 20 as per the question.
Therefore, x = 5.
Now, we can write that the HCF is 5.
So, the number of rotten apples ≡ HCF × 10 = 5× 10 = 50.
