Hi please help me I'm confused
If 8% of a number is 4, what is 12% of a number? Explain your reasoning.
Answer:
6
Step-by-step explanation:
The easiest way of solving this is to divide 8% of the number into a % that is divisible by 12.
This is 4%.
So if 8% of the number is 4, then 4 percent is half of 4, that is 2.
Now we convert 4% into 12% thus making it 6
Hope this helps
A more complicated way of doing this, but most reliable is to work out what the number is .
For now let number be y.
8/100 x y = 4
8y/100 = 4
8y= 400
y = 50.
Now calculate 12% of 50.
This is
12/100 x 50 = 6
Hope this helps.

Answer:
Median=3, Mean=2.333
Step-by-step explanation:
The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 57 and a standard deviation of 7. Using the empirical rule (as presented in the book), what is the approximate percentage of lightbulb replacement requests numbering between 50 and 57
Answer:
34%
Step-by-step explanation:
According to the empirical rule, 68% of all of the data in a normal distribution falls within one standard deviation of the mean.
Applying to this particular case, 68% of the requests fall within (50 - 7) and (50+ 7). The percentage of requests from 43 to 50 is equal to the percentage of requests from 50 to 57.
Therefore, the percentage of light bulb replacement requests numbering between 50 and 57 is 68/2 = 34%.
If a sample of 234 customers were taken from a population of 3620 customers, could refer to the variance of how many of the customers' ages?
If a sample of 234 customers were taken from a population of 3620 customers, s^2 could refer to the variance of how many of the customers' ages?
A. 234
B. 3620
C. Both 234 and 3620
D. Neither 234 nor
3620
Answer: 234
Step-by-step explanation:
Sample distribution = 234 customers
Population distribution = 3620 customers
S^2 which in statistics refers to the same variance utilizes the sample data in estimating the variance value of a population.
The sample variance is given by:
s^2 = (x - mean) / n - 1
where ;
n = number of observation in sample
s^2 = sample variance
mean = statistical mean of sample data
n - 1, is used to account for the bias in our estimation or inference of a population statistics from sample data.

Answer:
21/20, or 1.05.
Step-by-step explanation:
In this case, the measure of angle R is the same as angle V.
To find the tangent of a triangle, you do opposite over adjacent.
So, the tangent of angle V is 21 / 20.
That means that tan(R) = 1.05.

Point M divides line segment AB, in the direction from A to B, in a ratio of 5 to 3. What value on the number line would indicate the location of point M? A = --6, B = 3
Answer:
The coordinates of point M is -0.375.
Step-by-step explanation:
Given that point A = -6 and point B = 3
Point M divides line segment AB in the direction from A to B in the ratio of 5 to 3 we have;
Length from A to M = 5/(5 + 3) × Length of segment AB
Given that length of segment AB = 3 - (-6) = 3 + 6 = 9, we have;
Length from A to M = 5/8 × 9 = 45/8 = [tex]5\frac{5}{8}[/tex] = 5.625
Therefore, the coordinates of M = -6 + 5.625 = -0.375 = -3/8
The coordinates of point M = -0.375.
What is the answer of .7 of which is 3.43
Answer:
4.9
Step-by-step explanation:
3.43/0.7
34.3/7=49
3.43/0.7=4.9
The value of x is approximately 4.9 when 0.7 (70%) of x is equal to 3.43.
We are given that 0.7 (which is the same as 70%) of a certain value (x) is equal to 3.43.
We represent "0.7 of x" as 0.7x.
So, the equation becomes:
0.7x = 3.43
To find the value of x, we need to isolate it on one side of the equation. To do this, we can divide both sides of the equation by 0.7:
(0.7x) / 0.7 = 3.43 / 0.7
The 0.7 on the numerator and denominator cancel out, leaving us with just x:
x = 3.43 / 0.7
Now, we perform the division:
x = 4.9
The value of x is approximately 4.9.
Hence, when 0.7 (70%) of 4.9 is calculated, it will be approximately equal to 3.43.

x/3 = -9 plz solve this
Answer:
x=-27
Step-by-step explanation:
To solve this equation, we need to find out what x is. Therefore, we must get x by itself.
x/3= -9
x is being divided by 3. We want to perform the inverse operation, which is multiplication. Multiply both sides of the equation by 3.
3*(x/3)=-9*3
x= -9*3
x=-27
Let’s check out solution. Plug -27 back in for x.
x/-3= 9
-27/-3=9
9=9
This checks out, so we know our solution, x= -27, is correct.
What is the width of the prism if there is 4ft and 2ft and the volume is 24 cubic feet
Answer:
It is 3 ( i think )
Step-by-step explanation:
Which function represents g(x), a reflection of f(x) = Two-fifths (10)x across the x-axis? g(x) = Negative two-fifths(10)x g(x) = Negative two-fifths (one-tenth) Superscript x g(x) = Two-fifths (one-tenth) Superscript negative x g(x) = Two-fifths(10)-x
Answer:
The correct option is;
g(x) = Negative two-fifths(10)x
Step-by-step explanation:
The rule for the reflection across the x-axis is as follows;
Reflection about the x-axis
Pre-image point before reflection = (x, y)
Point of image after reflection = ((x, -y)
Therefore, the x coordinate remains the same while the y coordinate changes sign
For which given that f(x) = y = 2/5(10)x and g(x) = Reflection of f(x) across the x-axis, we have
Reflection about the x-axis
Pre-image point before reflection = (x, f(x))
Point of image after reflection = (x, g(x))
Hence g(x) = -f(x) = -2/5(10)x.

What is the slope-intercept equation for the line below?
(0.1) (4. 3)
Answer:
y=1/2x+1
Step-by-step explanation:
You can use the equation (y1-y2)/(x1-x2) to find the slope of the line with the given points. You put your y-values on top and x values on bottom, subtracting them to get 3-1/4-0. Then you simplify to get 2/4 or 1/2 as the slope. You then get y=1/2x+b. You can use one of the given points as x and y to solve for b. using (0,1) as x and y you get the equation 1=1/2(0)+b, after multiplying you get 1=0+b, or 1=b. Now that you have b you can make the equation, y=1/2x+1.

Question 2 Part A Use your responses to the previous questions, as well as your economic knowledge and terminology, to compose two well-written paragraphs that respond to the following question: What is the potential impact on the South African communities local economy from the game reserves investment in the clinic? Be sure to use these concepts in your writing: human capital health care PPC GDP infrastructure Your paragraphs should include a topic sentence as well as introductory and concluding sentences.
Answer: The game reserve’s investment in the clinic has the power to transform the rural South African community shown in the video. The game reserve is an important source of income for the community. The money from the reserve benefits the community by facilitating the building of infrastructure, such as schools and child-care facilities. These operations in turn generate employment.
The game reserve and the schools require a workforce and human capital. However, the workforce in the rural area is vulnerable to deadly diseases because of the HIV epidemic and poor sanitation. By investing in a mobile clinic and giving free medical treatment to those in the community, the game reserve can nurture its human capital and extend life expectancy in the area. If people are healthy and educated, they can work, be productive, and participate in community development. By protecting the workforce from death and disease, the game reserve can drive economic growth.
Step-by-step explanation:
Answer:
The investment for the game reserve is in the center and has the ability to change the country, South African people group appeared in the video. The game hold is a significant type of revenue for the local area. The cash from the hold benefits the local area by encouraging the structure of framework, for example, schools and kid care offices. These activities thus produce business.
The game reserve and also schools require a labor force and human resources. Notwithstanding, the labor force in the country territory is defenseless against destructive sicknesses due to the HIV pandemic and helpless disinfection. By putting resources into a portable facility and giving free clinical treatment to those locally, the game hold can support its human resources and broaden future nearby. On the off chance that individuals are sound and taught, they can work, be beneficial, and partake in local area improvement. By shielding the labor force from death and infection, the game hold can drive financial development.

Suppose you were deciding on a ticket price for a fundraiser dinner. There may be a temptation to continue to raise the ticket sales to increase the amount of money raised. Sounds like an okay idea to raise the most money possible for a charity. You may have heard of a guest speaker at a fundraising dinner where people are charged $100 a plate or more. What do you think is a realistic price for tickets? What are the consequences of raising the price $50 or $100 to $150 a plate or $200 a plate.
Answer:
$50 per ticket.
Step-by-step explanation:
Although it is tempting to keep raising the price for a higher profit, if you raise the price by too much, people will stop buying tickets and you will not gain as much money as you could have gotten with, say, $50 per plate.
The more you raise the price, the less tickets you can sell.

Answer:
Option (A)
Step-by-step explanation:
From the graph attached,
y ≤ [tex]-\frac{1}{3}x+3[/tex]
This inequality representing the dark line having y-intercept as 3 will have the solution area represented by the shaded region below the line (b and C)
Another inequality, y ≥ 3x + 2 representing a dark line having y intercept 2.
This inequality will have the solution area represented by shaded region on the left of the line (A and D)
Therefore, solution to the system of inequalities will be the common area (D).
Option (A) will be the answer.
The production of rice increased by 50% from 1995 to 1996 by what percentage should the production of rice be increased from 1996 to 1997 so that the production of prize in 1997 become six times that of 1995
Answer:
300%
Step-by-step explanation:
Let the production of rice in 1995 be x.
From 1995 to 1996, the production increased by 50%
This implies that the production of rice is now:
(100 + 50) / 100 * x = 150/100 * x = 1.5x
It means the production is now 1.5 that of 1995.
We want the production in 1997 to be 6 times that in 1995, that is 6x, this implies that we have to find the percentage increase from 1996 to 1997:
(100 + P) / 100 * 1.5x = 6x
By cross-multiplying:
100 + P = 6x * 100 / 1.5x
100 + P = 400
P = 400 - 100
P = 300%
Therefore, the production must be increased by 300%.
