factor 2w+6
Please explain? I'd like to understand how you did it so that I can do it myself the next time, thanks a mil :)
Answer:
2( w + 3 )
Step-by-step explanation:
Well first off, since theres no common term to factor out, I had to split 6 in half
so 2 w + 6 becomes 2w + 2 x 3.
I then factored out 2 because it's a common term,
which then leaves: 2( w + 3 )
basically, you have to find a common term to factor out, if you don't see one, you have to do something to a number so there's common terms.

On September 16, 2011, the New York Times reported that the American public's approval rating of Congress had sunk to an all-time low of 12%. Suppose we wanted to carry out another poll the following week. How many individuals must we survey to estimate the proportion who approve of Congress at that point to within 3% at 95% confidence?
Answer:
The sample size is [tex]n = 451 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is E = 0.03
The sample proportion is [tex]\^ p = 0.12[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{1.96}{0.03} ]^2 *0.12 (1 - 0.12 ) [/tex]
=> [tex]n = 451 [/tex]
This question is based on concept of normal distribution.Therefore, 451 individuals must survey to estimate the proportion who approve of Congress at that point to within 3% at 95% confidence.
Given:
The sample size is n=451.
According to question,
The margin of error is E = 0.03
The sample proportion is [tex]\bold{\hat{p}}[/tex] =0.12
From the question, the confidence level is 95% , hence the level of significance is,
[tex]\alpha =(100-95)\%\\\bold{\alpha =5\%=0.05}[/tex]
Normally, as per the normal distribution table the critical value of,
[tex]\dfrac{\alpha }{2}[/tex] is
[tex]\bold{Z_\frac{\alpha }{2} =1.96}[/tex]
And ,the sample size in mathematically represented as,
[tex]\begin{aligned}n&=(\frac{Z_\frac{a}{2} }{E})^{2} \times \hat p(1-\hat p)\\n&=(\frac{1.96}{0.03})^2 \times 0.12(1-0.12)\\\bold{n&=451} \end{aligned}[/tex]
Hence, there are 451 individuals must we survey to estimate the proportion who approve of Congress at that point to within 3% at 95% confidence.

The complete question is;
The following diagram(attached) shows how all the Grade Seven students of
Koronadal National Comprehensive High School go to school.
How many grade seven students of koronadal national comprehensive high school are there in all
Answer:
269 students
Step-by-step explanation:
From the venn diagram attached, we can see various given numbers of the students of the different modes of transport to school.
To get how many grade 7 students there are in total, we will add all the students inside the venn diagram simply because the set of grade 7 students are represented by those inside the venn the venn diagram while the number 100 outside the venn diagram is not a member of the set of grade 7 students which we are dealing with.
Thus,
Total number of grade 7 students = 76 + 19 + 15 + 17 + 55 + 20 + 67 = 269
Calc BC problems. Need work
Answer:
f'(0) = -2
f'(-2) = dne
[tex]\lim_{h \to 0^+} \frac{f(2+h)-f(2)}{h} = \text{does not exist}[/tex]
Step-by-step explanation:
The question specifically asks us to use the graph of the function to evaluate the following problems.
In order to find the derivative of a function at a specific point on the graph:
Choose the point on the graph where you want to find the derivative.Figure out the tangent line to this point; this will be the line tangent to the curve of the graph at this point.The slope of this tangent line is the derivative at this certain point on the graph.In order to find f'(0), find x = 0 on the graph. This is at the origin. Now, draw a line tangent to the curve of the graph at x = 0.
This tangent line will follow the same direction as the original function. So, we want to find the slope tangent line now - we can do so by finding the slope of the graph between the interval [-2, 2].
Slope of tangent line for f'(0):
Slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] Use coordinate points (-1, 2) and (1, -2)Slope of tangent line: [tex]\frac{-2-2}{1-(-1)} = \frac{-4}{2} =-2[/tex]The slope of the tangent line for f'(0) is -2, therefore, this is the derivative at this point on the graph.
This is solving the problem graphically/algebraically, but you could also look at the graph and determine the rise/run in your head. Your choice.
Now, for f'(-2), we cannot use the same process as before since the graph shows that there is a sharp point at x = -2. This is called a "corner" and means that while the function is continuous, it is not differentiable.
Therefore, we can write that at f'(-2), the derivative does not exist (dne).
The same process occurs for f'(2), since there is a sharp point here. The derivative, based on the graph, does not exist.

Find the inequality represented by the graph.
Can someone please help me!!!!!!
Answer:
[tex]y<-\frac{4}{3}x+5[/tex]
Step-by-step explanation:
We first need to determine the equation of the line.
Thus, we will need to find our slope first. To do so, we need to pick two points from the line. We can use (0, 5) and (3, 1).
Now, we can use the slope formula. Therefore:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, 5) be (x₁, y₁) and let (3, 1) be (x₂, y₂). Substitute appropriately:
[tex]m=\frac{1-5}{3-0}=\frac{-4}{3}[/tex]
Therefore, our slope is -4/3.
Now, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is our slope and b is the y-intercept.
We already determined that the slope is -4/3.
And (0, 5) tells us that the y-intercept is 5. Therefore, substitute:
[tex]y=-\frac{4}{3}x+5[/tex]
Finally, we need to determine our inequality sign.
Notice that our line is dotted. Hence, we do not need “or equal to.”
Also, the blue shaded region is below our line. Therefore, y must be less than our equation.
Hence, our sign is less than.
Therefore, our equation is:
[tex]y<-\frac{4}{3}x+5[/tex]
Solve for x: −7 x > 9

Step-by-step explanation:
3√7- √7 -2√7+√8 -5√7-3√2
=3√7- √7 -2√7 -5√7+√8 -3√2 (first we place similar radicands together)
=-5√7+√8 -3√2 ( solve the similar radicands)
=-5√7+√2³ -3 (2^1/2) ( break 8 into powers of 2)
=-5√7+ (2)^3/2 -3 (2^1/2) (solve 2 power with the radical sign)
= -5√7+(2^1/2){ 2-3} ( taking2^1/2 as common)
= -5√7+(2^1/2){ -1} ( solving the co - efficients of 2^1/2)
= -5√7 -1 (2^1/2)

In order to assess the opinion of students at the University of Minnesota on campus snow removal, a reporter for the student newspaper interviews the first 12 students he meets who are willing to express their opinion. The method of sampling used is:________.a. a censusb. a cluster samplec. a voluntary response sampled. a convenience samplee. a simple random sample
Answer:
Convenience sampling
Step-by-step explanation:
When a researcher gives more credence to ease when performing its sampling procedure, such sampling process may be referred to as convenience sampling. As described in the scenario above, rather than having to take a Systematic approach at examining the population so as to decide on the best sampling strategy to employ, the reporter of the student newspaper decides to take the easy path towards gathering the opinion of students by interviewing the first 12 students who are willing to give their opinion without any further consideration. Here, the reporter failed to eliminate any sort of possible bias which may be present, as all was sacrificed for the sake of convenience or ease.

Exercise 12-4 Pooling overhead cost LO 12-2 Stuart Manufacturing Company produced 2,600 units of inventory in January 2018. It expects to produce an additional 8,700 units during the remaining 11 months of the year. In other words, total production for 2018 is estimated to be 11,300 units. Direct materials and direct labor costs are $82 and $66 per unit, respectively. Stuart expects to incur the following manufacturing overhead costs during the 2018 accounting period:
Production supplies $ 6,200
Supervisor salary 188,000
Depreciation on equipment 134,000
Utilities 29,000
Rental fee on manufacturing facilities 224,750 Required
1. Combine the individual overhead costs into a cost pool and calculate a predetermined overhead rate assuming the cost driver is number of units. 2. Determine the cost of the 2,600 units of product made in January.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Total number of units= 11,300
Total overhead= 6,200 + 188,000 + 134,000 + 29,000 + 224,750= $581,950
To calculate the predetermined manufacturing overhead rate we need to use the following formula:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 581,950 / 11,300
Predetermined manufacturing overhead rate= $51.5 per unit
Now, we can calculate the total cost of making 2,600 units:
Total cost= (82 + 66 + 51.5)*2,600
Total cost= $518,700
