The mean absolute deviations for two sets of data are shown. The data points in Set 1 are more the mean than the points in Set 2 because the mean absolute deviation is .
Answer:
The data points in Set 1 are more spread out than the points in Set 2 because the mean absolute deviation of set 1 is larger.
Step-by-step explanation:
Given
Mean absolute deviations of set 1 and 2
Required
Complete the gap
From the complete question, we have that:
set 1 has a larger mean absolute deviation than set 2
This means that:
The dataset of set 1 is more spread out than that of set 2
The reason for this is that:
set 1 has a larger mean absolute deviation

Step-by-step explanation:
total cost of the meal = $120
tip = 20%
tip amount = ?
total cost of the meal with tip = ?
tip amount = tip% 0f total cost of the meal
=20/100 * $120
=$2400/100

Lucas suele gastar $150 en gaseosas al mes, pero, para cuidar su salud decidió dejar de consumir gaseosas ¿cuánto dinero a dejado de gastar en cinco meses?
Answer:
$750
Step-by-step explanation:
Primero, Lucas gastaba $150 cada mes en gaseosas.
Al decidir cuidar su salud, deja de comprar gaseosas, entonces ya no gasta esos $150 al mes.
Es decir, a dejado de gastar $150 al mes.
Nosotros queremos saber:
¿cuánto dinero a dejado de gastar en cinco meses?
Bueno, si en un solo mes a dejado de gastar $150
En 5 meses a dejado de gastar 5 veces esa cantidad, que es:
5*$150 = $750
In a regular polygon each interior angle is 120 greater than each exterior angle. Calculate the number of sides of the polygon.
Answer:
12 sides.
Step-by-step explanation:
the sum of every pair of interior and exterior angle is always 180 degrees.
x = exterior angle.
the interior angle is then x+120.
so then exterior and interior angle together must be 180.
x + x + 120 = 180
2x + 120 = 180
2x = 60
x = 30 degrees
how many sides ?
the sum of all exterior angles must be 360 degrees.
all exterior angles are the same (because all the interior angles must be the same due to "regular polygon").
so, how many times does 30 fit into 360 ?
360/30 = 36/3 = 12
it has 12 corners and also sides.
Please help me!!! Thank you.
Answer:
Rs 8160
Step-by-step explanation:
Principal = Rs 6000
Time = 3 years
Rate = 12%
Simple Interest = ?
Amount = ?
Simple Interest = PTR/100
=6000*3*12/100
=216000/100
=2160
Amount = principal + Interest
=Rs 6000 + Rs 2160
=Rs 8160
Step-by-step explanation:
Principal = Rs. 6000
Time = 3yrs 8months = 3⅔ yrs.
Rate = 12% pa.
SI = ?
Amount = ?
SI = PRT/100 = (6000×12×11)/(100×3) = 2640
Amount = SI+P = 2640+6000 = Rs. 8640

In parallelogram HJKL if m∡HJK=110∘ find m∡JKL.
Answer:
∠ JKL = 70°
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary , then
∠ JKL + ∠ HJK = 180°
∠ JKL + 110° = 180° ( subtract 110° from both sides )
∠ JKL = 70°

Solve [tex]27 = 3^4^x^+^1[/tex]
A. 1/4
B. 1/2
C. 2
D. 4
Answer:
1/2
Step-by-step explanation:
27 = 3 ^(4x+1)
Rewriting 27 as 3^3
3^3 = 3 ^(4x+1)
Since the bases are the same, the exponents are the same
3 = 4x+1
Subtract 1
3-1 = 4x+1-1
2 =4x
Divided by 4
2/4 = 4x/4

Factorize x2 + 7x + 12 using middle term break method.
Answer:
(x + 4)(x + 3)
Step-by-step explanation:
x^2 + 7x + 12
In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term. Factor each pair by finding common factors.
so we need two number that gives 12 when multiplied and 7 when added
4 and 3 are the numbers because 4*3 = 12 and 4+3 = 12
=x^2 + (4 + 3)x + 12
=x^2 + 4x + 3x + 12
=x(x + 4) + 3(x + 4)
take (x + 4) as common
=(x + 4) (x*1 + 3*1)
=(x + 4)(x + 3)

Which statement most reasonably explains the hours after the peak increase in temperature?
Answer:
C. The temperature increase went down because it became cooler as the sun went down for the night
Step-by-step explanation:
It is natural to have high temperatures when the sun is up, and as dusk begin to set, the temperature of a place drops. L
Going by the above stated fact, to explain the hours after the peak increase in temperature, it is plausible to conclude that as the sun went down, it became cooler for the night. That's why we have the lowest temperature displayed on the graph between 10 PM to 11:59 PM.

a) n(AUBUC) = 74
Find x
b) n(E)=100
(3)
Find y
(1
Answer:
The value of x is 4.
The value of y is 26.
Step-by-step explanation:
Here in qn a)
It has been given that n(AUBUC)=74
So we just add all components of n(AUBUC) and add it in an equation which equals to 74;
13 + 12 - x + x + 20 - x + 15 - x + 8 + 14 = 74
82 - 2x = 74
82 - 74 = 2x
8 = 2x
4 = x
So x is 4.
Now for qn b)
It has already been given that n(AUBUC) = 74 and n(U) = 100
so to find y we simply substract n(AUBUC) from n(U)
y = n(U) - n(AUBUC)
= 100 - 74
=26

Find the volume of a right circular cone that has a height of 18.8 m and a base with a
radius of 19.3 m. Round your answer to the nearest tenth of a cubic meter.
Step-by-step explanation:
Height of the right circular cone = 18.8 metres
And base is 19.3 metres
Volume of the right circular cylinder is given by,
= πr²h
= 3.14 × (19.3)² × 18.8
= 21999.98(approx.) cubic metre
Rounding off nearest tenth
= 21999 cubic metres
The volume of the right circular cone is 280,199.5 m³
What is a right circular cone?
'A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.'
According to the given problem,
Height = 18.8 m
Radius = 19.3 m
Volume of right circular cone = [tex]\frac{\pi r^{2}h }{3}[/tex]
= [tex]\frac{\pi * 19.3^{2} * 18.8}{3}[/tex]
= 280199.499 m³
= 280199.5 m³
Hence, we can conclude that the volume of the right circular cone is 280199.5 m³.
