Answer:

y = 1/2 x

Step-by-step explanation:

Given the table

X 2//4//8//10//16

Y 1//2//4//5//8

We are to find the equation that represent the table

Using the coordinates of x and y components from the table (2, 1) and (4, 2)

The standard expression for the equation is expressed as y = mx+c

m is the slope

c is the y-intercept

Get the slope;

m = y2-y1/x2-x1

m = 2-1/4-2

m = 1/2

Get the intercept c:

Substitute the point (2, 1) and the slope m = 1/2 into the expression y = mx+c

1 = 1/2(2) + c

1 = 1+c

c = 1-1

c = 0

Get the required equation

Recall that: y = mx+c

y = 1/2 x + 0

y = 1/2 x

Hence the required equation is y = 1/2 x

Answer:

Answer:

x = 18

Step-by-step explanation:

1/2 x - 7 = 1/3 (x - 12)           Remove the brackets on the right

1/2x - 7 = 1/3 x - 12*1/3

1/2x - 7 = 1/3 x - 4               Subtract 1/3 x from both sides

1/2x - 1/3x - 7 = - 4             Combine like terms on the left

1/6x - 7 = - 4                       Add 7 to both sides

1/6 x = - 4  + 7                    Combine the right side

1/6 x = 3                             Multiply both sides by 6

6 * 1/6x = 3*6

x = 18

Answer:

D

Step-by-step explanation:

If x is the first week, and he sold twice the amount so this could be represented as 1x (the first week) plus 2x (the second week since its twice the amount of the first week) and the third week can be represented as 1x-4 since its the same amount of candles sold minus 4. If you add them all together you get 1x+2x+1x-4. if you add like terms you get 4x-4. Hope this helps :)

Answer: c. 0.40396

Step-by-step explanation:

The total number of flaws is given by:

[tex]{\left({0}\times{4}\right)}+{\left({1}\times{3}\right)}(0\times4)+(1\times3) +{\left({2}\times{5}\right)}+{\left({3}\times{2}\right)}+(2\times5)+(3\times2) +{\left({4}\times{4}\right)}+{\left({5}\times{1}\right)}+(4\times4)+(5\times1) +{\left({6}\times{1}\right)}+(6\times1)={46}=46[/tex]

Average number of flaws for the 20 sheets : [tex]\displaystyle\mu=\frac{46}{{20}}={2.3}[/tex]

Required probability : [tex]=P(X\geq3)=1-P(X<3)[/tex]

[tex]=1-[P(X=0)+P(X=1)+P(X=2)][/tex]

[tex]=1-(\dfrac{e^{-2.3}2.3^0}{0!}+\dfrac{e^{-2.3}2.3^1}{1!}+\dfrac{e^{-2.3}2.3^2}{2!})\ \ \ [\text{Poisson distribution formula: }P(X=x)=\dfrac{e^{-\mu}\mu^x}{x!}]\\\\=1-0.596038825932=0.403961174068\approx0.40396[/tex]

Hence, c. is the correct option.

Answer:

Answer:

[tex]9x- 60=10[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{4}x - 5 = \frac{5}{6}[/tex]

Required

Rewrite to remove fractions

The denominators in the above expression are 4 and 6.

So, first we take the LCM of 4 and 6

[tex]LCM = 12[/tex]

Next, multiply both sides of the equation by this LCM (12)

[tex]12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12[/tex]

[tex]12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12[/tex]

[tex]3 * 3x- 60=5 * 2[/tex]

[tex]9x- 60=10[/tex]

Answer: $7.06

Step-by-step explanation:

$0.98 + $1.19 + $4.89 = $7.06

Answer:

$110.88

Step-by-step explanation:

Let L be the length of the first fence surrounding the garden and P its perimeter.

For a square, P = 4L,

So, L = P/4

Since P = 36 feet,

L = P/4

= 36/4

= 9 feet

Let L' be the length of the second fence. Given that second fence is 3 feet away from the first fence, it follows that L' = L + 3

= 9 + 3

= 12 feet.

So, the perimeter of the second fence is P' = 4L'

= 4 × 12 feet

= 48 feet.

So, the total length of the two fences is P" = P + P'

= 36 feet + 48 feet

= 84 feet

Since the cost of the material to build the two fences is $1.32 per foot, the total cost of the fences is cost per foot × total length of fences = $1.32 × 84 = $110.88

Primer rectangle:

Amplada = 11

Longitud = 14

Segon rectangle:

Amplada = 12

Longitud = 15

Tercer rectangle:

Amplada = 13

Longitud = 16

Explicació pas a pas:

Donat que:

Primer rectangle:

Amplada = x

Longitud = x + 3

2n rectangle:

Augment de la dimensió d'1 cm respecte al primer rectangle;

Amplada = x + 1

Longitud = x + 4

3r rectangle:

Augment de la dimensió de 2 cm respecte al primer rectangle;

Amplada = x + 2

Longitud = x + 5

Suma dels tres perímetres del rectangle:

Perímetre d'un rectangle: 2 (l + O)

Primer rectangle:

2 (x + x + 3) = 2 (2x + 3) = 4x + 6

2n:

2 (x + 1 + x + 4) = 2 (2x + 5) = 4x + 10

3r:

2 (x + 2 + x + 5) = 2 (2x + 7) = 4x + 14

Suma de perímetres = 162

(4x + 6 + 4x + 10 + 4x + 14) = 162

12x + 30 = 162

12x = 162 - 30

12x = 130

x = 11

Per tant,

Primer rectangle:

Amplada = 11

Longitud = 11 + 3 = 14

2n rectangle:

Amplada = 11 + 1 = 12

Longitud = 11 + 4 = 15

3r rectangle:

Amplada = 11 + 2 = 13

Longitud = 11 + 5 = 16

Step-by-step explanation:

sec330°

= 1 / cos330°

= 1 / cos30°

= 1 / (√3/2)

= 2/√3.

Answer:

[tex]\frac{2\sqrt{3} }{3}[/tex]

Step-by-step explanation:

Using the identity

secx = [tex]\frac{1}{cosx}[/tex] and cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sec330°

= [tex]\frac{1}{cos330}[/tex]

= [tex]\frac{1}{cos(360-330)}[/tex]

= [tex]\frac{1}{cos30}[/tex]

= [tex]\frac{1}{\frac{\sqrt{3} }{2} }[/tex]

= [tex]\frac{2}{\sqrt{3} }[/tex] ← rationalise the denominator

= [tex]\frac{2}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex]

= [tex]\frac{2\sqrt{3} }{3}[/tex]
