Evacuate the following expression for z=197.

Answer:

  see attached

Step-by-step explanation:

If you plot the points on the graph, you notice that the run (change in x) is 3 for each "rise" (change in y) of -1, so the slope is ...

  m = rise/run = -1/3

The middle point is on the y-axis, so is the y-intercept.

In slope-intercept form, the equation is ...

  y = mx + b . . . . . . where m is the slope (-1/3) and b is the y-intercept (4)

  y = -1/3x +4 . . . . equation

Answer:

x = 2 or x = -3

Step-by-step explanation:

Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.

Thus:

[tex] RT = BC [/tex]

[tex] (x^2 + x) = 6 [/tex]

Solve for x

[tex] x^2 + x = 6 [/tex]

Subtract 6 from each side

[tex] x^2 + x - 6 = 6 - 6 [/tex]

[tex] x^2 + x - 6 = 0 [/tex]

Factorise

[tex] x^2 + 3x - 2x - 6 = 0 [/tex]

[tex] x(x + 3) -2(x + 3) [/tex]

[tex] (x - 2)(x + 3) [/tex]

x = 2 or x = -3

Answer:

100 seconds

Step-by-step explanation:

12 arrows in 20 seconds

60 is 5 times of 12

multiply 20 by 5

Responder:

60 triángulos

Explicación paso a paso:

La pregunta está incompleta. No se dio el área del cartón. Digamos que la dimensión del cartón es de 2 m por 0,9 m.

Área del cartón = Largo * Ancho

Dado;

Longitud = 2 m

Ancho = 0,9 m

Área del cartón = 2 * 0.9

Área del cartón = 1.8m²

Si María decide recortar rectángulos con un área igual a 0.03 m², la cantidad de rectángulos que puede obtener del tablero se expresa como;

Número de rectángulos = área del cartón / área de cada parte recortada

Número de rectángulos = 1.8 / 0.03

Número de rectángulos = 60 rectángulos.

Por tanto, el número de rectángulos que puede recortar es de 60 rectángulos.

Tenga en cuenta que se asumió el área del rectángulo y que se puede emplear el mismo cálculo para cualquier otra dimensión dada.

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.

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.

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.

Step-by-step explanation:

first step is to find the gradient of the line which "m" on the equation

gradient formula is y2 - y1 ÷ x2 - x1 = -½ as shown on the picture we substituted those points given

2nd step is to substitute on the equation y=mx+c

m= -½

y= 3 (you can choose any from those given points but in my case I chose point A)

x= -2

c= ? only unknown variable so we can can calculate it

substitute as shown on the picture to get c= 2

therefore our equation of the line will be y= -½x+2

i think its 5.652 hope it helps

Step-by-step explanation:

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

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:

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):

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.

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
