A real-estate agent conducted an experiment to test the
effect of selling a staged home vs. selling an empty
home. To do so, the agent obtained a list of 10
comparable homes just listed for sale that were currently
empty. He randomly assigned 5 of the homes to be
"staged," meaning they were filled with nice furniture and
decorated. The owners of the 5 homes all agreed to
have their homes staged by professional decorators.
The other 5 homes remained empty. The hypothesis is
that empty homes are not as appealing to buyers as
staged homes and therefore, sell for lower prices than
staged homes. The mean selling price of the 5 empty
homes was $150,000 with a standard deviation of
$22,000. The mean selling price of the 5 staged homes
was $175,000 with a standard deviation of 35,000. A
dotplot of each sample shows no strong skewness and
no outliers.

The name of the appropriate inference procedure is a t-test for a difference in means.
What is a t-test?A t-test can be defined as a type of inferential statistic which is typically used to compare and show a significant difference between the means of two (2) groups that are drawn from a normally distributed data set (population).
This ultimately implies that, the name of the appropriate inference procedure to conduct a hypothesis test in this scenario is a t-test for a difference in means.

The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.
Answer:
109.75
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 8.5*6=51
rec 2: (9.5-5)*(13.5-5-6)=11.25
rec 3:5*9.5=47.5
Then:
51+11.25+47.5=109.75

Find the measure of the angle indicated by the red arrow.
Given side a is 41 units, side b is 23 units and the included angle is 70°. Find the area
Answer:
886.13sq. units
Step-by-step explanation:
If the figure is a triangle
Area of the triangle = 1/2 ab sintheta
Given
a = 41 units
b = 23 units
theta = 70°
Area of the triangle = 1/2 * 41 * 23 sin 70
Area of the triangle = 943 sin70
Area of the triangle = 943(0.9397)
Area of the triangle = 886.13
Hence the area of the triangle is 886.13sq. units

Answer:
volume of cyclinder=πr²h
=3.14×2²×3=37.68cm³
rectangular prism volume=6×5×7
=210cm³
total volume=37.68+210=247.68cm³
Step-by-step explanation:
1) Cylinder
d = 4 cm
h = 3 cm
r = d : 2
= 4 : 2
= 2
V. Cylinder = πr²h= 3.14 × 2² × 3
= 37.68 cm³
2) Rectangular prism
l = 6 cm
w = 5 cm
h = 7 cm
V = l . w . h= 6 . 5 . 7
= 210 cm³
3) Total Volume
V. Cylinder + V. Rectangular prism= 37.69 + 210
= 247.68 cm³

Answer:
37 degrees
Step-by-step explanation:
A triangle has to be 180 degrees so you do 53+90 (because it is a right triangle) equals 143
then do 180-143 to get your final angle of 37
Answer:
37 degrees
Step-by-step explanation:
The degrees of a triangle will add up to equal 180 degrees. A right angle will always be equal to 90 degrees.
Set up an equation:
Variable x = degrees of the acute angle
90 + 53 + x = 180
143 + x = 180
143 - 143 + x = 180 - 143
0 + x = 37
x = 37

Using mathematically precise language, explain in detail how you would multiply the complex number
z1=r1 (cos theta1+isin theta 1)
with the complex number
z2=r2 (cos theta 2+isin theta 2)
r-radius/radii
m-modulus/moduli
theta-argument represent angle theta
The product complex number is z1z2 = r1r2[cos (θ1+θ2) + isin (θ1+θ2)]
[tex]Z_1\times Z_2= r_1(cos \theta_1 + isin \theta_1) \times r_2(cos \theta_2 + isin \theta_2)[/tex]
r-radius/radii
m-modulus/moduli
theta-argument represent angle theta
[tex]= r_1r_2(cos \theta_1 + i sin \theta_1) (cos \theta_2 + isin \theta_2)[/tex]
[tex]= r_1r_2(cos \theta_1 cos \theta_2 + i cos \theta_1 sin \theta_2 + i sin \theta_1 cos \theta_2 + i^2sin\theta_1sin\theta_2[/tex]
What is the value of i square in complex number?The value of i square is
[tex]i^2=-1[/tex]
Therefore,we get,
[tex]= r_1r_2(cos \theta_1 cos \theta_2 + i cos \theta_1 sin \theta_2 + i sin \theta_1 cos \theta_2 + (-1)sin \theta_1 sin \theta_2)[/tex]
[tex]= r_1r_2(cos \theta_1 cos \theta_2 + i cos \theta_1 sin \theta_2 + i sin \theta_1 cos \theta_2 - sin \theta_1 sin \theta_2)[/tex]
Since we know that,
[tex]cos(\theta_1+\theta_2)=cos\theta_1cos\theta_2-sin\theta_1sin\theta_2[/tex]
[tex]sin(\theta_1+\theta_2)=sin\theta_1cos\theta_2+cos\theta_1sin\theta_2[/tex]
So using above value we get,
[tex]= r_1r_2(cos \theta_1 cos \theta_2 - sin \theta_1 sin \theta_2) + i (cos \theta_1 sin \theta_2 + sin \theta_1 cos \theta_2)[/tex]
[tex]=r_1r_2cos(\theta_1+\theta_2)+isin(\theta_1+\theta_2)[/tex]
Therfore the product of the complex number is z1z2 = r1r2[cos (θ1+θ2) + isin (θ1+θ2)].
