Answer: 36
Step-by-step explanation: First you will convert 3/10 into 0.3. Then you will multiply it by 120 by setting it up like this:
120
0.3
For now ignore the decimal and add it later when you are done. I hope this helps!

Who has the greater mean absolute deviation, and by how much? Show or explain how you know.
Answer:
#1
150*(1 - 5/8) = 150(3/8) = 56.25Option A#2
56.80 + 22.70x = 374.6022.7x = 374.60 - 56.8022.7x = 317.8x = 317.8/22.7x = 14 months#3
Blue = 20 - (9 + 5) = 6p(blue) = 6/20 = 0.3 or 30%#4
3 3/4 + 20% of 3 3/4 =3 3/4*1.2 = 15/4 * 12/10 =9/2 = 4.5 hr#5
Actual value = 72 in, expected value = 68 in
Error = 72 - 68 = 4 inPercent error = error/ expected value * 100% = 4/68*100% = 5.9% (rounded)#6
d + 8% = d + 0.08d = 1.08dd*1.08 = 1.08d#7
Michael
Data = 42, 43, 45, 4.7, 48Mean = (42+ 43+ 45+ 47+ 48) / 5 = 45Absolute deviation = (|42 - 45| + |43 - 45| + |45 - 45| + |47 -45| + |48 - 45|)/5 = 2Nadia
Data = 36, 37, 46, 50, 51Mean = (36+ 37+ 46+ 50+ 51)/5 = 44Absolute deviation = (|36 - 44| + |37 - 44| + |46 - 44|+ |50 -44| + |51 - 44|)/5= 6Nadia had greater mean absolute deviation: 6 - 2 = 4 (seconds)

3d + 6 = 4d + 9
3d - 4d = 9 - 6
-d = 3
d = - 3
A matea le encanta dibujar barquitos.Si traslado su barquito inicial 1 des veces,(2 y 3) ¿Cómo desplazo cada uno de sus puntos?
Answer:
Luego de una búsqueda online, encuentre más información sobre esta pregunta, la cual se puede ver en la imagen del final.
Básicamente lo que tenemos que hacer en este tipo de problemas, es estudiar como los puntos del barco uno cambian cuando hacemos cada transformación, usualmente con un par de puntos ya podremos notar un patrón, y de esta forma entender la transformación que utilizo para mover la figura.
Para conocer las coordenadas de cada punto tenemos que ver el valor de x asociado (el eje horizontal) y el valor de y asociado (el eje horizontal), notar que cada punto está representado por una letra, esto nos permite asociar a los puntos de los distintos barcos.
Entonces, en la transformación de (1) a (2), los cambios en los puntos son:
A (1, 7) --> A₁ (11, 11) (sumamos 10 al eje x, sumamos 4 al eje y)
B (0, 9) --> B₁ (10, 13) (sumamos 10 al eje x, sumamos 4 al eje y)
C (3 , 9) --> C₁ (13, 13) (sumamos 10 al eje x, sumamos 4 al eje y)
Ok, ya con 3 puntos podemos notar un patrón, sea (x, y) un punto cualquiera en el barco (1), el correspondiente punto en el barco (2) va a ser (x + 10, y + 4), esta es la regla utilizada para mover el barco de (1) a (2), lo que es equivalente a decir que movió el barco 10 unidades a la derecha, y 4 unidades para arriba.
Ahora Mateo vuelve a mover el barco, esta vez de (2) a (3).
De vuelta, tenemos que ver como los puntos del barco (2) cambian, y tratar de encontrar un patrón:
A₁ (11, 11) --> A₂ (9, 1) (restamos 2 en el eje x, restamos 10 en el eje y)
B₁ (10, 13) --> B₂ (8, 3) (restamos 2 en el eje x, restamos 10 en el eje y)
C₁ (13, 13) --> C₂ (11, 3) (restamos 2 en el eje x, restamos 10 en el eje y)
De vuelta, ya tenemos suficiente información como para notar el patrón, para un punto (x, y) del barco (2), el correspondiente punto en el barco (3) se escribe como (x - 2, y - 10).
Es decir, movemos el barco (2) 2 unidades para la izquierda y 10 unidades para abajo, asi llegando al barco (3).

Answer:
x = 63°
it is an isosceles triangle, so K and M are equal
Step-by-step explanation:
let K be x, since K=M means both equals x
x + x + 54° = 180°
2x + 54° = 180°
2x = 180° minus 54°
2x = 126°
x = 63°
to prove
63° + 63° + 54° = 180°

Find the length of arc AB. Use 3.14 for pi. Round to the nearest tenth.
Answer:
arc AB = 12.40°
Step-by-step explanation:
diameter = 7.9 x 2 = 15.8
circumference = 15.8 x 3.14 = 49.612
since the central angle of arc AB is 90 °
90/360 x 49.612 = 12.40

Kenya is trying to find matching socks. There are 4 red socks, 6 blue socks, and 2 white socks in her drawer. What is the probability that Kenya will pull out a blue sock, put it on, and then pull out another blue sock to put on?
Answer:
1/3 is the probaility
Step-by-step explanation:
since there are 3 different socks the answer would be 1/3
Answer:
The probability of her pulling of a blue sock the first time is 6 out of 12
The probability of her pulling out a blue sock the 2nd time would be 5 out of 11
Solve quickly please.
Find the change between the first two sets:
12-9 = 3
14.4 - 10.8 = 3.6
3.6/3 = 1.2
Now find the change between the last two sets:
12 - -3 = 15
14.4 - 3.6 = 10.8
10.8/15 = 0.72
1.2 does not equal 0.72 so the answer is No
Nora and Rachel were the fastest two swimmers at the swim meet .Nora finishing time was 25.04 and Rachel’s was 25.4 .Nora was so happy .She believed she had tied with Rachel, Rachel said good job Nora but I won .Who is correct?
Answer:
Nora Won
Step-by-step explanation:
In a swimming contest you would go for the least time, so, let's see who had the least time:
20 = 20 (Tens places)
5 = 5 (Unit place)
0 < 4 (Tenths place)
So, Nora was the winner and she was faster than Rachel by 0.36 seconds

The following are the ages (years) of 5 people in a room:
23, 20, 15, 12, 17
A person enters the room.
The mean age of the 6 people is now 19.
What is the age of the person who entered the room?
Answer:
multiply 6 by 19 to get the total age of the six people in the room then add the ages of the 5 people in the room and subtract it from the total of the 6 to get your answer
Answer:
27
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be the age of the person entering the room , then
[tex]\frac{23+20+15+12+17+x}{6}[/tex] = 19 ( multiply both sides by 6 )
87 + x = 114 ( subtract 87 from both sides )
x = 27
The age of the person who entered the room is 27

22 The distance around a meteor crater is 9,031 ft. Find the diameter of the crater. Use 22/7
(Type an integer or decimal rounded to the nearest tenth as needed.)
Answer:
d = 2873.5 feet
Step-by-step explanation:
Given that,
The distance around a meteor crater is 9,031 ft.
We need to find the diameter of the crater. The circumference of a circle is given by :
[tex]C=2\pi r[/tex]
Where
r is the radius of the circle
So,
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{9031}{2\times \dfrac{22}{7}}\\\\r=1436.75\ ft[/tex]
Since,
Diameter, d = 2r
[tex]d=2\times 1436.75\\\\d=2873.5\ ft[/tex]
So, the diameter of the crater is equal to 2873.5 feet.

Jimmy takes gets a student loan to go to college after high school. If he pays $9,000 in interest at a rate of 3% for 4 years, what is the principal amount borrowed?
Answer:Principal=$7,500,000
Step-by-step explanation:
Interest =(Principal X Rate X time ) / 100
Given
Interest =$9,000
rate = 3%
Time= 4 years
Principal=(Interest X 100) / rate X time
Principal,=(9000x 100)/3% x 4
Principal=$7,500,000
