The display gives sale prices for 40 houses in Ames, Iowa sold during a recent month. The mean sale price was $203,388 with a standard deviation of $87,609. Find the percentile of the house indicated in red on the dotplot
Answers
Answer:
Step-by-step explanation:
The percentile of the house indicated in red on the dotplot is "[tex]62^{nd}[/tex] percentile".
Given values are:
Number of houses,
40Mean sale price,
μ = $203,388Standard deviation,
σ = $87,609Now,
→ [tex]z = \frac{230,000-203,388}{87,608}[/tex]
→ [tex]= \frac{26,612}{87,608}[/tex]
→ [tex]=0.30[/tex]
By using the table, we get
→ [tex]= 0.6179[/tex]
Thus the above answer is appropriate.

what is y - 1 = -5/2(x + 2) in pre-algebra standard form
Answers
Answer:
y=-5/2x-4
Step-by-step explanation:
y-l=-5/2(x+2)
Distribute the -5/2 to (x+2)
y-1=-5/2x-5
Add on on both sides of the equal sign
y=-5/2x-4

the slope is 5 passing through ( -1, 4)
Answers
Answer:
y = 5x + 9
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, thus
y = 5x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = - 5 + c ⇒ c = 4 + 5 = 9
y = 5x + 9 ← equation of line
Write an equation in slope-intercept form of the line with slope 3/4 that contains the point (-4,1)
Answers
Answer:
y = 3/4x + 4
Step-by-step explanation:
to put it into slope intercept form, you need to find the y intercept or b becasue the slope intercept form is y = mx + b where b is the y intercetpt and m is the slope. To find b you insert the points you were given so 1 = -4(3/4) + b
which simplifies to 4 = b so then you can put in your slope and y intercept into slope intercept form

How many integers between 2020 and 2400 have four distinct digits arranged in increasing
order? (For example 2957 is one such integer)
(B) 10
(C) 15
(D) 21
e 28
Answers
Answer:
the answer is E
Step-by-step explanation:
We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.
We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.
---------------------------
To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.
If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).
so we have:
23__
The number next to the 3 can be a 4, for example:
234_
And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.
If instead of a 4, the number next to the 3 is a 5, we have:
235_
And the number next to the five can be any digit larger than 5, so now we have 4 options.
If instead of a 5, we have a 6, we will have 3 options to put after the 6.if instead of a 6, we have a 7, we will have 2 optionsif instead of a 7, we have an 8, we will have 1 option.Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.
Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:
5 + 4 + 3 + 2 + 1 = 15
This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.

1) Roger has four dollars more than double the amount that Roderick has in his wallet. Together, they have a total of $224. How much money does Roger have?
Answers
Answer:
$150.66
Step-by-step explanation:
Let that amount of money Roger has = x
The amount of money Roderick has = y
Roger has four dollars more than double the amount that Roderick has in his wallet.
x = 2y + 4
Together, they have a total of $224.
x + y = $224....... Equation 1
We substitute 2y + 4 for x in Equation 1
2y + 4 + y = $224
3y + 4= $224
3y = $224 - 4
3y = $220
y = $220/3
y = $73.333333333
y = $73.33
How much money does Roger have?
x = 2y + 4
x = 2(73.33) + 4
x = $146.66 + 4
x = $150.66
Roger has $150.66

using the slope formula find the slope of the line through the points (0,0) and (3,9) use pencil and paper explain how you can use mental math to find the slope of the line
Answers
Answer:
The answer is 3
Step-by-step explanation:
The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,
Slope = (y₂ - y₁)/(x₂ - x₁)
Since the given line is passing through (0,0) and (3,9).
Slope = (9 -0)/(3 - 0)
Slope = 3
Since the line is passing through the origin (0,0) so we can do it by mental math to divide y and x coordinate directly like 9/3 = 3.
Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3".
