Halla la suma de los infinitos términos de la progresión geométrica si r= 1/5 y a1=1/2
Answers
Answer:
5/8
Step-by-step explanation:
Aquí, queremos encontrar la suma al infinito de la progresión geométrica, dado el primer término y la razón común Matemáticamente, eso sería;
S = a/1-r
S = 1/2/(1-1/5)
S = 1/2/4/5
S = 1/2 * 5/4
S = 5/8

A construction crew has just finished building a road. The crew worked for 4 1/5 days. If they built 2 1/3 kilometers of road each day, what is the total length of road they built?
Answers
Answer:
9.8
Step-by-step explanation:
The crew worked for 4 1/5 days
They built 2 1/3 kilometres of road each day
Therefore the total length of the road can be calculated as follows
= 4 1/5 × 2 1/3
= 21/5 × 7/3
= 147/15
= 9.8
Hence the length of the road is 9.8 kilometres
A car manufacturer produced 5,000 cars for a limited edition model. Dealers sold all of these cars at mean price
of $36,000 with a standard deviation of $3,000. Suppose we were to take random samples of 9 of these cars
and calculate the sample mean price z for each sample.
Calculate the mean and standard deviation of the sampling distribution of 2.
H(x)=_________dollars
O(x)=_________dollars
Answers
Answer:
μₓ = 36,000 dollars
σ ₓ= 1,000 dollars
Step-by-step explanation:
to find μₓ = 36,000 dollars:
Look in the question, it states that the mean is $36,000.
to find σ ₓ= 1,000 dollars:
[tex]\frac{3000}{\sqrt{9} } = 1000[/tex]
The mean and standard deviation of the sampling distribution is $36000 and $1000.
What is Standard Deviation?
The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
The mean and the standard deviation of the sampling distribution of the sample mean:
Mean, [tex]\mu[/tex] = $36000
[tex]\sigma[/tex] = 3000
n = 9
So, standard deviation of the sampling distribution
= [tex]\sigma[/tex] / √n
= 3000 / √9
= 3000/3
= 1000
Hence, Mean = $36,000 and standard deviation = $1000.

There are 32 sticks in the game. The sticks are either orange (x) and red (y). There are 5 more red sticks than twice the number of orange sticks Write the two equations in order to solve the system and then tell me how many orange and red sticks are in the game.
Answers
Answer:
orange = 9 sticks
Red = 23 sticks
Step-by-step explanation:
orange = x
Red = y
x + y = 32
There are 5 more red sticks than twice the number of orange sticks
y = 2x + 5
x + y = 32
x + 2x + 5 = 32
3x = 32 - 5
3x = 27
x = 27/3
x = 9 sticks
y = 2x + 5
= 2(9) + 5
= 18 + 5
y = 23 sticks
orange = 9 sticks
Red = 23 sticks
A bird starts at 20m and changes to 16m? The bird's final elevation is
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
The initial elevation is 20m
According to the question :
If it changes to 16m, then the final elevation of the bird is 16 m.
However, in some texts, the question goes thus;
A bird starts at 20m and changes 16m? The bird's final elevation is?
In this case, the initial height = 20m
Change in height = 16 m (positive means ascension)
Hence,
initial height + change in height
20 m + 16 m
= 36m
Which linear equation can be used to represent a line perpendicular to Line W passing through point (-3,-2)?
line on graph is x=8 Help please
Answers
Answer:
D) y = -2
The equation of the perpendicular line to the given line is y = -2
Step-by-step explanation:
Explanation:-
Given point (-3,-2)
In graph the equation of line x = 8 ( parallel to y- axis )
1 x + o y - 8 =0
The equation of the perpendicular line to the given line
b x - a y + k =0
o x - 1 y + k =0 ...(i)
The equation (i) is Paases through the point ( -3,-2)
0 ( -3) -1(-2) + k =0
2 + k =0
k = -2
∴The equation of the perpendicular line to the given line is
put k = -2 in equation (i)
o x - 1 y + k =0
- y +(-2) =0
- y = 2
y = -2
Final answer:-
∴The equation of the perpendicular line to the given line is y =-2
Write an equation of the line that passes through (3,2) and is perpendicular to the line y= 1/3x-3
Answers
Answer:
y = - 3x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 9 + c ⇒ c = 2 + 9 = 11
y = - 3x + 11 ← equation of perpendicular line

Which size Dairy Queen blizzard gives you the best price per ounce
Small 6oz. Cup for $2.49
Large 16oz. Cup for $4.98
Medium 10oz. Cup for $3.49
Supper size 24oz. Cup for 7.69
Answers
medium- 3.49/10 = 0.349 per oz
large- 4.98/16= 0.31125 per oz
super size- 7.69/24= 0.32 per oz
therefore large is the best price!
The Large blizzard has the lowest cost per ounce at $ 0.31125/oz
Given data ,
To determine the best price per ounce for Dairy Queen blizzards, we can calculate the cost per ounce for each size option:
Small: 6 oz. for $2.49 ->
Cost per ounce = $2.49 / 6 oz. = $0.415/oz.
Large: 16 oz. for $4.98 ->
On simplifying the equation , we get
Cost per ounce = $4.98 / 16 oz. = $ 0.31125/oz.
Medium: 10 oz. for $3.49 ->
Cost per ounce = $3.49 / 10 oz. = $0.349/oz.
Super Size: 24 oz. for $7.69 ->
On simplifying the equation , we get
Cost per ounce = $7.69 / 24 oz. = $0.32042/oz.
Comparing the cost per ounce for each size option, we can see that the Small blizzard has the highest cost per ounce at $0.415/oz. The Large blizzard has the lowest cost per ounce at $ 0.31125/oz.
Hence , the Large blizzard gives you the best price per ounce among the options provided.

A telephone poll of an SRS of 1234 adults found that 62% are generally satisfied with their lives. The announced margin of error for the poll was 3%. Does the margin of error account for the fact that some adults do not have telephones
Answers
Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling

Find all values of x that make the triangles congruent. Explain your reasoning.
Answers
Answer:
The values of x that make the triangles congruent.
x = 6 and x = 3
Step-by-step explanation:
Given
AC = 5x-2DC = 3x+10AB = 5xDB = 4x+3Given that the triangles are congruent.
According to the SAS (Side-Side-Side)
AC = DC
AB = DB
so
AC = DC
substituting AC = 5x-2 and DC = 3x+10
5x-2 = 3x+10
5x-3x = 10+2
2x = 12
divide both sides by 2
2x/2 = 12/2
x = 6
and
AB = DB
substituting AB = 5x and DB = 4x+3
5x = 4x+3
5x-4x = 3
x = 3
Therefore, the values of x that make the triangles congruent.
x = 6 and x = 3
