Answer:

  x - 4

Step-by-step explanation:

The expression simplifies to ...

  [tex]\sqrt{x^2-8x+16}=\sqrt{(x-4)^2}=|x-4|[/tex]

For x ≥ 4, the argument of the absolute value function is non-negative, so it remains unchanged. The simplified expression is ...

  x - 4 . . . . for x ≥ 4

Answer:

(a) (0.9240,  0.956)

(b) (0.6383, 0.7017)

Step-by-step explanation:

The number of internet users involved in the survey, n = 846

The percentage of the respondents that said the internet has been good thing for them personally, [tex]\hat p[/tex] = 94%

(a) The confidence interval of a percentage is given as follows;

[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

The z-value for 95% confidence interval = 1.96

We get;

[tex]CI=0.94\pm 1.96\times \sqrt{\dfrac{0.94 \times (1-0.94)}{846}} \approx 0.94 \pm 1.6003 \times 10^{-2}[/tex]

CI = 0.9240 ≤ [tex]\hat p[/tex] ≤ 0.956 = (0.9240,  0.956)

(b) The percentage of the internet users that said the internet has directly strengthened their relationship with their families, [tex]\hat p[/tex] = 67% = 0.67

The 95% confidence interval is therefore;

[tex]CI=0.67\pm 1.96\times \sqrt{\dfrac{0.67 \times (1-0.67)}{846}} \approx 0.67 \pm 3.1686\times 10^{-2}[/tex]

From which we have;

CI = 0.6383 ≤ [tex]\hat p[/tex] ≤ 0.7017 = (0.6383, 0.7017)

Answer:

Basic wage rate = $9.375 per hour

Step-by-step explanation:

Given :

Fortnight wage = $750

Basic week, hours worked per week = 40 hours

Weekly basic wage rate :

Fortnight = 2 weeks

Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375

Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour

Answer:

So B has the greatest value of slope.

Step-by-step explanation:

A has a negative slope, so A is out.

B, C and D all have positive slopes.

B has a greater slope than C, so C is out.

B has a finite slope, and D has a "slope" of infinite, but much of the time it does not count, because we do not make calculations with infinite slopes, and infinity is not a number (value).

So B has the greatest value of slope.

Answer:

no

Step-by-step explanation:

Answer:

a.

Step-by-step explanation:

Step-by-step explanation:

the function A, according to the tables

=> the equation : f(x) = 2x +3

the slope = 2

the function B, according to the graph

=> the equation : f(x) = 3x -2

the slope = 3

based on the value of the slope, the function B has a greater rate of change

Answer:

Step-by-step explanation:

Find the slope for the two functions

Function A:

(1 , 5)  & (2 , 7)

Slope = Change in y ÷ change in x

         [tex]= \frac{7-5}{2-1}\\\\= \frac{2}{1}\\\\= 2[/tex]

Function B:

(1 ,1) , (2 , 4)

Slope = [tex]= \frac{4-1}{2-1} = \frac{3}{1}[/tex]

             = 3

Function B has a greater rate of change

Answer:

  (x, y, z) = (-1, 0, -3)

Step-by-step explanation:

We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.

Adding equations 1 and 2:

  (2x -3y -2z) +(x +3y +2z) = (4) +(-7)

  3x = -3

  x = -1

Adding equations 2 and 3:

  (x +3y +2z) +(-4x -4y -2z) = (-7) +(10)

  -3x -y = 3

Substituting for x, we get ...

  (-3)(-1) -y = 3

 0 = y . . . . . . . . . . . add y-3 to both sides

Then z can be found from any equation. Substituting for x and y in the second equation gives ...

  -1 +2z = -7

  2z = -6 . . . . . add 1

  z = -3 . . . . . .divide by 2

The solution is (x, y, z) = (-1, 0, -3).

Answer:

0.563

Step-by-step explanation:

Probability is defined by the amount of desirable outcomes over the total number of outcomes. When rolling a 16 sided number cube, there are 16 different numbers you can roll, which means 16 total outcomes. There are 8 odd numbers that you can possibly roll:

1, 3, 5, 7, 9, 11, 13, 15

Now, an even prime numbers are included in the desirable outcomes too. The only even prime number is 2. Since the odd numbers and even prime numbers do not have common term, to get the total desirable outcomes, you can add the two: 8 + 1 = 9. From the basic probability formula you can say the probability is 9/16 or 0.5625. This rounds to 0.563.

If you were too lazy to calculate, you can realize that 0.563 is the only reasonable answer because it is close to 1/2 or 0.5 and half the numbers are odd and only one is even and prime which makes the amount a bit over 1/2.

Answer:

slope = 1

Step-by-step explanation:

A standard linear function is

y = mx + b

where m = slope, b = initial value

Given y = x + 6

slope m = 1, b = 6

Slope of a line parallel to the given line should have the same slope, therefore slope required is m = 1.

Answer:

total eggs=2+4+2

=8

for orange eggs=2/8

=1/4

=0.25

Answer:

2/8 decimal form is 0.25

Step-by-step explanation:

there's 2 orange and in total there's 8 and if u divide 8 divided by 2 it will be 0.25

Point K is in the 4th quadrant, then it goes into the first quadrant. So this means the rotation could be 90 degrees counterclockwise or 270 degrees clockwise.

The answer is 90 degrees counterclockwise or 270 degrees clockwise.

Step-by-step explanation:

Answer:

x = 25

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

2x+10 + 4x+20 = 180

Combine like terms

6x+30 = 180

Subtract 30 from each side

6x+30-30 = 180-30

6x = 150

Divide by 6

6x/6 = 150/6

x=25

Answer:

A) 2

Step-by-step explanation:

The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.

sin(A)/a=sin(B)/b=sin(C)/c

Substitute the known values into the law of sines to find a.

sin(60)/a=sin(60)/2

Answer:

0.5857 radian

Step-by-step explanation:

Given :

Length of fence = 6 feets

Height of fence from ground after tilt = 5 feets

The tilt angle is represented by θ ;

To obtain the angle ; we use the trigonometric relation :

Cosθ = adjacent / hypotenus

Cos θ = 5 / 6

θ = Cos^-1(5/6)

θ = 33.557°

Converting to radian :

33.557 * π/180

= 33.557 * 0.0174532

= 0.58568

= 0.5857 radian

Answer:

1. 33.39

2. 164.29%

3. 6,400

4. X = 4

5. X = 150

Step-by-step explanation:

1. The answer to question number one is 33.39

When you are trying to find a percentage of some number, you turn the percent part (in this case 63%) into it's decimal form, which is 0.63. Then you take that decimal and multiply it by the whole (which is 53.) That is 33.39.

2. The answer to question number 2 is 164.29%.

For this question you can set up an expression :

The question is 23 is what percent of 14. In expression form, using x as the "what percent" part the equation would look like this :

23 = x · 14

The equal sign means "is" and "of" means multiply. So, to solve for x, we divide. 23 divided by 14 is 1.6429, and now you just turn that into a percentage. The answer to this is 164.29%.

3. The answer to question number 3 is 6,400.

This question is really asking 128 is 2% of what? Again, you can turn this into an expression.

128 = 0.02 · x

We need to solve for x, so we divide. 128 divided by 0.02 is 6,400. So the answer to this one (question 3) is 6,400.

4. X = 4

Eight times a number, increased by 6 (which means add 6) is 62. We need to turn this into an algebraic equation to solve. Our mystery number can be "x", so let's try that.

8x + 6 = 62

That is our algebraic equation, now we solve for x.

Subtract 6 on both sides of the equation :

8x + 6 - 6 = 62 - 6

8x = 56

Now that the 6 is gone, you divide by 8 on both sides to get x.

56 divided by 8 is 7. X is 7 for question number 4.

5. X = 150

Again, turn this question into an algebraic equation.

X ÷ 6 = 25

That is the algebraic equation, now you solve for x. We want to get rid of the "divide by 6" part, and the opposite of dividing is multiplying. We multiply that "divide by 6" by 6, so that cancels out. We must multiply by 6 on the other side too, so 25 · 6 is 150. X is 150.

Answer:

( 1 ) 33.39

( 2 ) 60.9%

( 3 ) 6,400

( 4 ) 8(7) + 6 = 62

( 5 ) (150) ÷ 6 = 25

Step-by-step explanation:

Finding the ANSWER being a percent of a number: percent * number = answer

63% * 53 = 33.39

Finding the PERCENT of a number is the answer: answer ÷ number = percent (tip: move the decimal point two spaces to the right to get the percentage; round the percent when necessary)

14 ÷ 23 = 60.9

Finding the NUMBER being a percent of it is the answer: answer ÷ percent = number

128 ÷ 2% = 6,400

Answer:

y + 16 = -1(x + 3)²

Step-by-step explanation:

Looking at the graph, parabola vertex opens upwards with x intercepts as -5 and -1.

Thus, the line of symmetry will be;

x = (-5 + (-1))/2 = -3

Looking at the graph we can see that the vertex when traced to the x - coordinate will be 3 which is same with what we got.

Now, the general form of the equation will be;

y - h = a(x - k)²

where (k,h) is the vertex coordinate

Thus, k = -3

So;

y - h = a(x - (-3))²

>> y - h = a(x² + 6x + 9) =

>> y = ax² + 6ax + 9a + h

When, x = 0

y = 9a + h

From the graph, we can see that the y-intercept is y = -25

Thus;

9a + h = -25

From the graph, h which is the y-coordinate of the vertex = -16

Thus;

9a - 16 = - 25

9a = -25 + 16

9a = -9

a = -9/9

a = -1

Thus, the equation is;

y - (-16) = -1(x - (-3))²

>> y + 16 = -1(x + 3)²
