B.  If square-foot is on the x-axis then we can substitute for x in the equation and solve, and when we do, we get 2473.302 which is is B when rounded.

Answer:

The correct option is b.

Step-by-step explanation:

It is given that y-axis of a scatter plot represents the property taxes and x-axis represents the sizes of their homes, in square feet.

The equation of least squares regression line is

y=2.098x-254.098

We have to find the property taxes to be for a 1300-square-foot home in the area.

Substitute x=1300 in the given equation.

y=2.098(1300)-254.098

y=2727.4-254.098

y=2473.302

y\approx 2473.30

The property taxes for a 1300-square-foot home in the area is $2473.30. Therefore the correct option is b.

The floor of a hall has an area of 48 dm.The floor is to be tiled by triangular tiles.of sides 20 cm,30 cm and 40 cm. Find the t
vovangra [49]
The triangle is an obtuse triangle. No sides are equal.
convert cm to dm

1 dm = 10 cm

side a: 20 cm ⇒ 20cm * 1dm/10cm = 20dm/10 = 2 dm
side b: 30 cm ⇒ 30cm * 1dm/10cm = 30dm/10 = 3 dm
side c: 40 cm ⇒ 40cm * 1dm/10cm = 40dm/10 = 4 dm

We need to get the area of a triangle, but first we need to solve for its height using Heron's formula

s = (a+b+c)/2 = (2+3+4)/2 = 9/2 = 4.5
<span>Area = </span>√<span>(s(s-a)(s-b)(s-c)
</span>h3/2 = √4.5(4.5-2)(4.5-3)(4.5-4)
h3/2 = √4.5(2.5)(1.5)(0.5)
h3/2 = √8.44
h3/2 = 2.91
h = (2.91*2)/3
h = 1.94

A = hb/2 = (1.94*3)/2 = 5.82/2 = 2.91 dm²

48 dm² / 2.91dm² = 16.5 or 17 tiles needed

17 x Rs200 = Rs3,400 is the total cost

vovikov84 [41]
Median is a better measure of center than the mean(average)

a) 56,62,68,71,104,507 ⇒ Median is a better measure. Mean is not a better measure because of the outliers.

b) 2,8.5, 9.2, 9.8, 10.1 lb ⇒ Median is a better measure. 

c) Mean is a better measure. No outliers. Data set values are close with each other.

Identify an equation in slope-intercept from for the line parallel to y=-3x + 7 that passes through (2, -4)
alexandr1967 [171]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

The parallel lines have the same slope.

We have y = -3x + 7 → m = -3. Therefore y = -3x + b.

Put the coordinates of the point (2, -4) to the equation of a line:

-4=-3(2)+b

-4=-6+b            <em>add 6 to both sides</em>

2=b\to b=2

<h3>Answer: y = -3x + 2</h3>
