Answer:
10 times greater is the value of 5 in 3,590 than the value of 5 in 359.
Step-by-step explanation:
Suppose that the store manager of a small rural pharmacy is doing a linear regression of daily sales of over-the-counter (OTC) decongestant nasal sprays on forecasted pigweed pollen count. He would like to determine if he can use a straight ine equation to predict OTC decongestant nasal spray sales from the allergy forecast for pigweed pollen. The store manager records the data for five random days. The pollen forecast is for pigweed only and is given in parts per square meter (ppm )2
Pollen forecast OTC decongestant sales (dollars)
14 $101
19 $89
13 $48
6 $21
9 $47
The store manager calculates the regression equation for the data as 5.514x-6.073.
Determine the standard error of the slope of the regression line, SEb, for the data. Give your answer precise to at least three decimal places SE=______.
Answer:
3.83
Step-by-step explanation:
Mean of x = Σx / n
Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2
Sum of square (SS) :
(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8
Mean of y = Σy / n
Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2
Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8
df = n - 2 = 5 - 2 = 3
Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6
√(Σ(y - ybar)² / df) = √1449.6 = 38.074
Standard Error = √(Σ(y - ybar)² / df) / √SS
Standard Error = 38.074 / √98.8
Standard Error = 3.83

√2x^2 ·√4x
the answer is: 2x sqrt 2x
The expression √(2x²) · √(4x) is equivalent to the expression 2x√2x. Then the correct option is D.
What is an equivalent expression?The equivalent is the expressions that are in different forms but are equal to the same value.
The expressions are given below.
√(2x²) and √(4x)
Then the product of the expressions √(2x²) and √(4x) will be
⇒ √(2x²) · √(4x)
The factor of 2x² will be
2x² = 2 · x · x
The factor of 4x will be
4x = 2 · 2 · x
Substitute in the expression, then the expression will be
⇒ √(2 · x · x) · √(2 · 2 · x)
We know that √x² = x and √4 = 2. Then the expression will be
⇒ x√2 · 2√x
⇒ 2x√2x
Thus, the expression √(2x²) · √(4x) is equivalent to the expression 2x√2x.
Then the correct option is D.

Two sets of three consecutive integers have a property that the product of the larger two is
one less than 7 times the smallest. Set up and solve an equation that can be sue to find both
sets of integers. What are those sets of integers?
Answer:
{1, 2, 3}, {3, 4, 5}
Step-by-step explanation:
Write expressions for three consecutive integers: n, n + 1, n + 2.
Set up an equation for the verbal description: the product (mulitplication) of the two larger integers (the last two) is one less than 7 times the smallest (the first one).
(n + 1)(n + 2) = 7n - 1
Multiply (FOIL) the left side.
n^2 + 3n + 2 = 7n - 1
Subtract 7n and subtract 1 to make the right side 0.
n^2 - 4n + 3 = 0
Factor.
(n - 1)(n - 3) = 0
Set the two factors equal to 0
n - 1 = 0, n - 3 = 0
Solve for n.
n = 1, n = 3
One set of integers begins with 1, so it's {1, 2, 3}.
The other set begins with 3, so it's {3, 4, 5}

Answer: B
Step-by-step explanation: if you look from both sides u can see it adds up + i got it right on edg:)
The statement describes the behavior of the function around the vertical asymptotes is B.
We have given the graph,
We have to determine which statement describes the behavior of the function around the vertical asymptotes.
What is the vertical asymptotes?
A vertical asymptote is a vertical line that guides the graph of the function but is not part of it. It can never be crossed by the graph because it occurs at the x-value that is not in the domain of the function. A function may have more than one vertical asymptote.
If you look from both sides of the graphs you can see it adds upward.

Answer:
Relation 1: Not a function
Relation 2: Not a function
Relation 3: Function
Relation 4: Not a function
Step-by-step explanation:
Recall: a relation can only be a function if and only if each domain value has only 1 range value mapped to it or related to it. This means that a domain value can only have exactly one range value for the relation to be qualified a function.
✔️Relation 1 is NOT A FUNCTION.
Rationale: Two of the domain values (star and sky) is having more than 1 range value assigned to each.
✔️Relation 2 is NOT A FUNCTION:
Rationale: domain value, 9, has several range values assigned to it.
✔️Relation 3 is A FUNCTION:
Rationale: each domain value do not have more than one range values assigned to it.
✔️Relation 4 IS NOT A FUNCTION:
Rationale: the domain value, 6, has two range values, m and d, assigned to it.

What is the value of 0.5–0.05? Write your answer as a fraction in lowest terms.
Answer:
Heyaaa!!! I'm Pinky!! And i'm here to inform you that you're answer is...
Step-by-step explanation:
!!!
0.5–0.05= 0.45
0.45 In fraction form is Simply:
9/20 (And that's on lowest terms!)
If you would want it in percentage form to that would simply be:
45%
Have A Nice Day!!!!
~Pinky~
The value of 0.5–0.05 is a fraction in the lowest terms = 9/20.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written as the form of p: q, which is equivalent to p / q.
The given expression is: 0.5–0.05
Subtract 0.05 from 0.05
0 . 5 0
-0. 0 5
0 . 4 5
So, 0.5–0.05 = 0.45
Multiply and divide by 100 we get,
[tex]0.45\times \dfrac{100}{100} = \dfrac{45}{100}[/tex]
Divide both the numerator and denominator by 5 we get,
[tex]\dfrac{45}{100} = \dfrac{9}{20}[/tex]
Hence,
0.5–0.05 in the lowest fraction is 9/20.

What value of X makes the equation true -7x - (-5-x) = -9(2x-1) -1
Answer:
x = 1/4
Step-by-step explanation:
-7x - (-5-x) = -9(2x-1) -1
-7x + 5 + x = -18x + 9 - 1
combine like terms:
-6x + 5 = -18x + 8
add 18x to each side of the equation:
12x + 5 = 8
subtract 5 from each side:
12x = 3
divide both sides by 12:
x = 3/12 = 1/4
