Answer:
x = 7
y = 8
Step-by-step explanation:
The following data were obtained from the question:
Data => 4, 6, х, y, 10
Mean = Median
x =?
y =?
Next, we shall determine the mean of the data. This can be obtained as follow:
Data => 4, 6, х, y, 10
Mean =?
Mean = summation of data / number of data
Mean = 4 + 6 + х + y + 10 / 5
Mean = 20 + х + y / 5
Next, we shall determine the median of the data. This can be obtained as follow:
Data => 4, 6, х, y, 10
Median =?
Median = the middle term of data
Median = x
Next, we shall equate the mean and median. This can be obtained as follow:
Mean = 20 + х + y / 5
Median = x
Mean = Median
20 + х + y / 5 = x
Cross multiply
20 + х + y = 5x
Collect like terms
20 + y = 5x – x
20 + y = 4x
Make y the subject
y = 4x – 20
Case 1
Let x = 7
y = 4x – 20
y = 4(7) – 20
y = 28 – 20
y = 8
Mean = 20 + х + y / 5
Mean = 20 + 7 + 8 / 5
Mean = 35/5
Mean = 7
Median = x
x = 7
Median = 7
Mean = median = x = 7
Case 2:
Let x = 8
y = 4x – 20
y = 4(8) – 20
y = 32 – 20
y = 12
We can see that y is 12 which means that the data (i.e 4, 6, х, y, 10) would become 4, 6, х, 10, y. But from the question, we were told that the data (i.e 4, 6, х, y, 10) is in order. Therefore if y is 12, the order would be altered.! And this is not acceptable.
From the above illustration, we can conclude that:
x = 7
y = 8
Divide 1170 denars in a ratio of 2: 3: 8.
Answer:
180:270:720
Step-by-step explanation:
total units-> 13u
1 unit -> 1170÷13=90
2u->90×2=180
3u->90×3=270
8u->90×8=720
3/4 + 1/3x = 6 Solve for x
[tex] \frac{3}{4} + \frac{1}{3}x = 6 [/tex]
Multiply both sides of the equation by 12
[tex]9 + 4x = 72[/tex]
Move constact to the right-hand side and chancge it's sign.
[tex]4x = 72 - 9[/tex]
Subtranct the numbers
[tex]4x = 63[/tex]
Divide both sides the equation by 4
Solution:

Answer:
10/8 or 1.25
Step-by-step explanation:
We can write this into an equation to help us understand what we need.
3/4=0.60x
We can make these both into fractions to make it easier.
3/4=6/10x
Divide both sides by 6/10, or multiply both sides by 10/6.
3/4×10/6=30/24=10/8=1.25

If a point lies on a line then every point that lies on the line also lies on it besides that point. In other words if line is a subset of R2 plane every point not in R2 but in line is by definition every point on the line or simply a line.

25x + 15y=305$
Neee answer ASAP
Answer:
1st. Problem
Let's solve for x.
25x+15y=17
Step 1: Add -15y to both sides.
25x+15y+−15y=17+−15y
25x=−15y+17
Step 2: Divide both sides by 25.
25x/25 = -15y+17/ 25
x equals...
x= -3/5 y + 17/25
2nd. Problem
Let's solve for x.
25x+15y=305
Step 1: Add -15y to both sides.
25x+15y+−15y=305+−15y
25x=−15y+305
Step 2: Divide both sides by 25.
25zx/25 = -15y305/25
x equals...
x = -3/5 y + 61/5

Answer:
I'm not 100% sure, but I do think it is
0.042768
But it is asking for percentage, and says to round 3 decimal places, making it confusing whether you round 0.042768 first, or you round the percentage of 4.2768%. I would argue with your teacher, as the excuse of why this was turned in late.
Step-by-step explanation:
It is either 4.277% or 4.3%.
Yes, you may wonder why the second possibility is just a rounded form of the first answer. It is due to rounding to three decimal places first, as 0.042768 rounded to three places is 0.043 because the 7 is more than 4 blah blah blah kiddy rhymes from elementary school yeah.
That would become 4.3%.
But 0.042768 if you turn it to a percent first is 4.2768% which becomes 4.277% if you round it afterwards. Argue this to a teacher or something.
Exercise 1.6 introduces a study on the relationship between socio-economic class and unethical behavior. As part of this study 129 University of (California Berkeley undergraduates were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others.
A. Identify the population of interest and the sample in this study.
B. Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
(A) Population: UCB undergraduates
Sample: The selected 129 UCB undergraduates
(B) Yes, they can be generalized to the population
No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.
Step-by-step explanation:
STUDY: Relationship between socio-economic class and unethical behavior.
The bases for determining social class here are: money, education, and respected job.
RESULT: Those who identified as upper class took more candy than others.
(A) Identify the population of interest and the sample, in this study.
The population of interest in this study is UCB undergraduates.
The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.
(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.
The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.

Consider this quadratic equation.
x + 2x + 7 = 21
The number of positive solutions to this equation is ____
The approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is _____
Answer:
1 solution
2.88
Step-by-step explanation:
Consider this quadratic equation.
x ^2+ 2x + 7 = 21
Subtract 7 from both sides
x ^2+ 2x + 7 -7= 21-7
x^2+2x = 14
x^2+2x -14 = 0
Factorize
x = -2±√2²-4(-14)/2
x= -2±√4+56/2
x = -2±√60/2
x = -2±7.75/2
x = -2-7.75/2 and -2+7.75/2
x = -9.75/2 and 5.75/2
x = -4.88 and 2.88
Hence there are 1 number of positive solution
The approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is 2.88
Answer:
The number of positive solutions to this equation is
1
The approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is

John can walk 6 dogs in 3 hours. Susie can walk 7
dogs in 2.5 hours. How long would it take them to
walk 15 dogs together?
Answer:
It would take them 6.5 hours to walk 15 dogs together.
Step-by-step explanation:
John can walk 2 dogs in 1 hour.
If you multiply that by 3, he can walk 6 dogs in 3 hours.
So that means he can walk 8 dogs in 4 hours.
Susie can walk 7 dogs in 2.5 hours.
Meaning that if you add 8 dogs plus 7 dogs, you get 15 dogs.
Meaning that if you add 4 hours plus 2.5 hours, you get 6.5 hours.
That being said, they can both walk 15 dogs TOGETHER in 6.5 hours.

Answer:
x = -10
Step-by-step explanation:
1) A line creates a 180° angle on each side of it. Even if another line intersects it, we know that the total measure of angles on that side will equal 180°.
2) We set the equations equal to 180.
(-4x) + (-14x) = 180
Combine like-terms
-18x = 180
Isolate x by dividing both sides by -18.
x = -10
3) To solve for each angle, you can plug in -10 for x and solve.
-4(-10) = 40°
-14(-10) = 140°

Given that M is the midpoint of line segment AC, AM = x + 20, and MC = 5x - 4. Find the lenght of AM.
Answer:
6 units
Step-by-step explanation:
AM = MC
AM = x + 20
MC = 5x - 4
x + 20 = 5x - 4
20 = 4x - 4
24 = 4x
x = 6
The required length of the AM is 27.
Given that,
M is the midpoint of line segment AC,
AM = x + 20, and MC = 5x - 4.
To find the length of AM.
The midpoint is that point the line whose distance from both the ends of the line is equal.
Here,
M is the midpoint of line segment AC, i.e.
AM = AC - - - - - - - - - - -- - - (1)
AM = x + 20, and MC = 5x - 4
Put AM and MC in equation 1
x + 20 = 5x - 4
5x - x = 20 + 4
4x = 24
x = 24 / 4
x = 7
Now,
Length AM = x + 20
Length AM = 7 + 20
Length AM = 27
Thus, the required length of the AM is 27.

can. The cost of each pair is $22.50. There is also
a single shipping charge of $6.50. How many
pairs of shorts can he afford without spending
more than his gift card amount? Write the
inequality, then solve, and state your answer.
Answer:
8 pairs

Answer:
10 pairs
22.50x+6.50<_250
Step-by-step explanation:
If you do 22.50 times 10 you get 225 then you add 6.50 which would give you 231.50. You cant add any more pairs of shoes because you would go over the $250 limit. For example if you added 22.50 one more time you would be at 254. Therefore it would be 10 pairs of shoes.
