Answer:

Tarea completa: 32 alumnos (4/5)

Sin tarea completa: 8 alumnos (1/5)

Step-by-step explanation:

Fracciones

Si un todo se divide en partes iguales o desiguales expresadas en fracciones, entonces la suma de esas fracciones debe ser 1, es decir, el 100% del todo.

Tenemos 40 alumnos como el total del grupo de sexto. Cuatro quintas partes de ellos llevaron las tareas completas, eso significa que:

[tex]\frac{4}{5}*40 =32[/tex]

alumnos llevaron las tareas completas. Para conocer el número de alumnos que no llevaron las tareas completas, restamos el total del anterior, es decir, 40-32=8 alumnos no llevaron la tarea completa.

Respuesta:

Tarea completa: 32 alumnos (4/5)

Sin tarea completa: 8 alumnos (1/5)

Stratified design with color of paper as the blocks

Step-by-step explanation:

The experimental design that this question uses is the stratified design with color of paper as the blocks

A stratified design is one where the population has been divided into strata that are homogeneous. A good number of participants would then be picked for each of the stratum. The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here.

The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students. The students in each levels are halved and each half is randomly assigned information on either a white paper or a blue paper.

Answer:

no

x = 4 - 3x    x = 1

2x = 4          x =2

hope this helped :D

Answer:

No. They are not equivalent. The first one would end up being x=1, while the second one would be x=2.

Step-by-step explanation:

Answer:

1/56

Total letters are 8

probability of first selecting c is 1/8 and since it's not replaced, probability of selecting e is 1/7

Total probability= 1/8*1/7=1/56

Therefore, total probability is 1/56

Answer:

Attached please find response.

Step-by-step explanation:

We wish to find the area between the curves 2x+y2=8 and y=x.

Substituting y for x in the equation 2x+y2=8 yields

2y+y2y2+2y−8(y+4)(y−2)=8=0=0

so the line y=x intersects the parabola 2x+y2=8 at the points (−4,−4) and (2,2). Solving the equation 2x+y2=8 for x yields

x=4−12y2

From sketching the graphs of the parabola and the line, we see that the x-values on the parabola are at least those on the line when −4≤y≤2.

In this exercise we have to use the function informed to identify the value of the formed figure, then:

[tex]x=4-12y^2[/tex]

Given the following information in the exercise statement:

Substituting y for x in the equation:

[tex]2y+y^2\\y^2+2y-8(y+4)(y-2)=8[/tex]

Analyzing the equation formed, we can see that it will have the shape of a parabola, and that the values ​​of x will be between:

[tex]X: -4\leq y\leq 2[/tex]

Answer:

0.606928 or 0.61 rounded to the nearest hundredth

Step-by-step explanation:

it is a cube so all sides are equal:

Volume= a^3

V=(1/3)^3

V=1/27 in^3

convert in^3 to cm^3

1 in^3               16.3871 cm^3

1/27 in^3           ????

[1/27(16.3871)]/1 = 0.606928 or 0.61 rounded to the nearest hundredth

Answer:

There is no difference in the number of sales between The Florida salespeople and Washington salespeople

Sp^2 = 39

Step-by-step explanation:

Given data :

Florida: 39, 44, 42, 50, 55, 48, 51, 38, 54

Washington: 42, 43, 56, 50, 49, 52, 53, 56

number of sales persons in Florida = 9

number of sales persons in Washington = 8

variance = constant

a)Determine if there is difference between the Florida salespeople and Washington salespeople

we will carry out a two tailed test based on the given data

H0 : u1 = u2  

H1 : u1 ≠ u2

x ( mean ) = 46.77,  y ( mean ) = 50.13 ,

s1^2 = 39.69,  s2^2 = 28.41,   n1 = 9 ,   n2 = 8

therefore :

Sp^2 = [tex]\frac{n1s1^2 + n2s2^2}{n1 + n2-2}[/tex] =  38.96  ≈ 39

performing test statistic

t = [tex]\frac{x- y }{sp\sqrt{\frac{1}{n1} +\frac{1}{n2} } }[/tex]    = [tex]\frac{-3.36}{3.0330}[/tex] = -1.1078

critical value is at t = 0.05 and for a two tailed test it is at 2.13  therefore e accept H0 at 5% .    This shows that there is no difference in sales

x=40 blue marbles

Answer:

You can multiply the brackets to make sure you get 4x² + 4x + 1. Since the numbers in the brackets are the same, we can just use one of them and let it equal to 0. Then solve it. ∴ The answer is x = -1/2.

Answer:

B. SAS

Step-by-step explanation:

Two sides of ∆DEF (DE and DF) are proportional to two corresponding sides of ∆ABC (AB and AC), and also their included angles (<D and <A) are equal to each other.

Therefore, based on the SAS criterion, both triangles are proven to be similar to each other.

Both triangles satisfy the SAD Criterion, and hence, they can be proven to be similar to each other.

Answer:

[tex]\boxed {\boxed {\sf About \ 11 \%}}[/tex]

Step-by-step explanation:

The formula for percent error is:

[tex]\% \ error = | \frac{measured \ value - actual \ value }{actual \ value} | *100[/tex]

For this, the measured value is the estimation of 40 grams. The actual value is the true mass of 45 grams.

[tex]measured = 40 \ g \\actual = 45 \ g[/tex]

[tex]\% \ error = | \frac{40 \ g - 45 \ g }{45 \ g } | *100[/tex]

Solve the numerator.

[tex]\% \ error = | \frac{-5 \ g }{45 \ g } | *100[/tex]

Divide.

[tex]\% \ error = | \frac{-5 \ g }{45 \ g } | *100[/tex]

[tex]\% \ error = | -0.111111111| *100[/tex]

[tex]\% \ error = 0.111111111*100\\\% \ error = 11.11111 \\\% \ error \approx 11[/tex]

The percent error is about 11%

The exponential equation that gives the number of residents in the community after 5 years is:

[tex]y(5) = 10^5[/tex]

It is modeled by:
