Answer:

=  -5√7 -(√2)

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)  

=  -5√7 -(√2)          {answer}

Answer:

18.2

Step-by-step explanation:

A way we can find the average is by finding the mean.

Mean is found when you add up all the numbers and divide by the total amount of values there are.

In this case there are 5 values in total.

[tex]\frac{17+24+19+17+14}{5}[/tex] = 91/5 = 18.2

Answer:

18.2

Step-by-step explanation:

add all values together and divide by number of values.

17+ 24+ 19+ 17+14

then divide by 5

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

Answer:

Option A

Step-by-step explanation:

In order to find the answer to this question you must change the mixed numbers into improper fractions and then solve.

[tex]1\frac{3}{4} \times\frac{2}{4}[/tex]

Convert into improper fraction:

[tex]4\times1=4+3=7[/tex]

(Remember to keep the denominator the same)

[tex]\frac{7}{4} \times\frac{2}{4}[/tex]

Now multiply:

[tex]7\times2=14[/tex]

[tex]4\times4=16[/tex]

[tex]=\frac{14}{16}[/tex]

Answer:

B) x = -3

Step-by-step explanation:

3x - 4 = 7x + 8.

Subtract 7 from 3

3 - 7 = -4

-4x - 4 = 8

use additive inverses.

-4x - 4 + 4 = 8 + 4

8 + 4 = 12.

-4x ÷ -4 = 12 ÷ -4

x = -3.

Step-by-step explanation:

i got it correct:)

S-32 is the expression to show the amount of soup Marta has left

An expression is combination of variables, numbers and operators.

Given,

Marta makes S ounces of soaps.

She always freezes 32 of the soap for remaining.

We need to find the expression to show the amount of soup Marta has left.

This can be done by the expression

S-32

where S is the number of ounces.

Hence, S-32 is the expression to show the amount of soup Marta has left

Answer:

-1 is the answer , your welcome haha

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:

[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]

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.

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.

Answer:

Width = 4 in

Length = 8 in

Step-by-step explanation:

Given:

Area of a rectangle = 32 in²

Find:

Length and width

Computation:

Assume;

Width = x

Length = x + 4

Area of a rectangle = lb

32 = (x+4)(x)

x² + 4x = 32

x² + 4x - 32 = 0

x² + 8x - 4x - 32 = 0

x(x+8) - 4(x+8) = 0

(x-4)(x+8)

x = 4 , x = -8

So,

Width = x = 4 in

Length = x + 4 = 4 + 4 = 8 in
