Answer:
4,200
Step-by-step explanation:
Tenemos un total de:
4 libros de matemáticas
3 libros de biología
3 libros de religión
10 libros en total.
Ahora vamos a contar la cantidad de opciones que tenemos para cada posicion.
Primer libro (tenemos 10 opciones)
segundo libro (tenemos 9 opciones, porque ya colocamos un libro)
tercer libro (tenemos 8 opciones, porque ya colocamos dos libros)
Con esto ya podemos estimar el número de opciones para cada posicion, y sabemos que el número total de combinaciones es igual al producto entre los números de opciones para cada caso. El número total de combinaciones es:
C = 10*9*8*7*6*5*4*3*2*1 = 10!
Ahora si asumimos que no podemos diferenciar los libros de matemáticas, entonces no debemos contar sus permutaciones (si tenemos 4 libros de matemáticas, tenemos 4*3*2*1 permutaciones = 4! permutaciones). Debemos dividir al numero total de combinaciones por 4!.
Y lo mismo pasa para las 3! permutaciones de los libros de biología y las 3! permutaciones de los libros de religión.
Entonces el número total de combinaciones diferentes es:
[tex]C = \frac{10!}{3!*4!*3!} = \frac{10*9*8*7*6*5*4*3*2*1}{(3*2*1)*(4*3*2*1)*(3*2*1)} = 4,200[/tex]

Written Response: Sally believes that 1/2% is equivalent to 50%. Is she correct? Why or why not?
Answer:
She is correct.
Step-by-step explanation:
1/2 and 50% is the same thing
50% is 1/2 of 100
The results of a survey asking 500 people about their favorite ice cream flavor are shown in the table.
Find the experimental probability of each outcome in the sample space. Enter your answers in the boxes.
Flavor Number of People
Chocolate 90
Vanilla 125
Strawberry 60
Mint Chip 50
Other 175
P(chocolate) =
%
P(vanilla) =
%
P(strawberry) =
%
P(mint chip) =
%
P(other) =
%
Chocolate = 18%
Vanilla = 25%
Strawberry = 12%
Mint Chip = 10%
Other = 35%
The explanation for me getting these exact percentages is because of the formulas given for calculating the percentages from specific numbers and real world problems like this. When you are trying to find the calculation precentages of these types of questions, you divide the number by the total surveyed and multiple by 100.
Example:
125 / 500 = 0.25
0.25 x 100 = 25%
So, this is also how I got the other numbers, just change the "125" to the other numbers.
The experimental probability of each outcome in the sample space are:
P(chocolate) = 18%, P(strawberry) = 12%, P(vanilla ) = 25%, P(mint chip) = 10% and P(other) = 35%
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Flavor Number of people
chocolate 90
strawberry 60
vanilla 125
mint chip 50
other 175
So, the Experimental probability are:
P(chocolate)= 90/ 500 x 100 = 18%
P(strawberry) = 60/ 500 x 100 = 12%
P(vanilla ) = 125/ 500 x 100 = 25%
P(mint chip) = 50/ 500 x 100 = 10%
P(other) = 175/ 500 x 100 = 35%

4x 75Step-by-step explanation:
Now I have never seen a question like this but it would make sense if the GCF is 5, 4x and 7 since 5 x 4x = 20x and 5 x 7= 35.
So the blank x would be 4 x, the right side would be 7 and the bottom left would be 5.

A. Skewed Right
B. Uniform
C. Skewed Left
D. Normal
Skewed Right I think. I'm not sure but try it
Answer:
C. Skewed Left
Step-by-step explanation:
Because the first 2 age group have minimal runners than the next 3 age groups spikes and the last 4 are very low once again. the spike occurs relavity near the beggining so if graphed it would be skewed left.
An aluminum can has a capacity of 2.37 L. What is the capacity of the can in milliliters?
(1 L = 1,000 mL)
Answer:
2,370 mL
Step-by-step explanation:
1000mL = 1 L, so I multiplied 1000 by 2.37
If they ask for it to be set up as a proportion, I would write 1/1000 = 2.37/x and cross multiply. x = 2,370

Question: Based on the data set above for the hours per day sixth graders spend using an electronic device, what is the mean number of hours sixth graders use an electronic device?
No links, useless words, or anything like that. I will report you.
Answer:
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
1+1+1+1+2+3=9
2+4+4+5+6+6+7+8+8=50
50/9=5.55555555556
or
9/50=0.18
The volume of a cone is 8003π cubic yards. The height is 8 yards. Find the radius
The volume of a cone is 8003π cubic yards. The height is 8 yards. Find the radius.
Solution:-Height (h) of a cone is 8 yards. (Given)
We have to find the radius (r) of a cone.
Now,
ATQ ,
[tex] \frac{1}{3} [/tex]πr²h = 8003π
[tex] \frac{1}{3} [/tex]r²h = 8003 [ ' π ' is cancelled from both sides ]
[tex] \frac{1}{3} [/tex]r² × 8 = 8003
r² = [tex] \frac{8003 \: × \: 3}{8} [/tex]
r² = [tex] \frac{24,009}{8} [/tex]
r² = 3001.125
r = [tex]\sqrt{3001.125}[/tex]
r = 54.78
The radius of a cone is 54.78 yards. [Answer]I need help QUICKLY on this algebra question!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

whats the slope using Rise/Run?
thanks, if you help
Answer:
the slope of the given line is m = rise / run = -1/2
Step-by-step explanation:
Going from (1, -1) to (3, -2), the 'rise' is actually a drop of 1 unit; the 'run' is +2.
Thus, the slope of the given line is m = rise / run = -1/2

Required data:
_______________
| 60 | 105 | 80 | 125 |
| 140 | 95 | 65 | 170 |
----------------------------
Answer:
Mean absolute deviation = 30
Variability of the data about the mean value is 30
Step-by-step explanation:
Mean = Σx / n
n = sample size = 8
Mean = (60 + 105 + 80 + 125 + 140 + 95 + 65 + 170) = 840 / 8 = 105
Mean absolute deviation = Σ|x - mean| ÷ n
( |60-105| + |105-105| + |80-105| + |125 - 105| + |140-105| + |95-105| + |65-105| + |170-105|) / 8
(45 + 0 + 25 + 20 + 35 + 10 + 40 + 65) / 8
240 / 8
= 30
The variability of data about the central point or mean value is 30.
how of find the area of a composite figure
Step-by-step explanation:
A composite figure is made up of simple geometric shapes. To find the area of a composite figure or other irregular-shaped figures, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure. Formula = a(a=lw+bh)
