Answer:

x = 9.6

Step-by-step explanation:

sin Q = 16/20 Q = 53.13° from the big triangle

16/20 = x/12

192 = 20x

x = 9.6

Answer:

z = 21 ; y= 16

Step-by-step explanation:

first of all we have to isolate a variable.

In second expression we can obtain:

3y = 2z+6

y = 2/3 z + 2

now we have to substitute this value in the first equation and solve it

8(2/3z+2)-5z = 23

16/3z + 16 -5z = 23

16z +48 - 15z = 69

z = 21

now we have to substitute z in the second equation:

y = 2/3 (21) +2

y = 14+ 2 = 16

y = 16

Answer:

x = -6

Step-by-step explanation:

We have the equation 3x - 4 = 2x - 10 and are asked to find "x".

To solve , we need to get "x" alone entirely.

3x - 4 = 2x - 10

Subtract 2x from both sides :

x - 4 = -10

Add 4 to both sides to get our answer :

x = -6

Answer:

The sample size required is of 2305.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

A preliminary survey of adult Americans has estimated this proportion to be somewhere around 0.40.

This means that [tex]\pi = 0.4[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The sample size required to estimate this proportion with 95% confidence and a margin of error of 0.02.

The sample size required is of n.

n is found when M = 0.02. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.02 = 1.96\sqrt{0.4*0.6}{n}}[/tex]

[tex]0.02\sqrt{n} = 1.96\sqrt{0.4*0.6}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.4*0.6}}{0.02}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.4*0.6}}{0.02})^2[/tex]

[tex]n = 2304.96[/tex]

Rounding up

The sample size required is of 2305.

Answer:

  a) w(4w-15)

  b) w²

  c) w(4w -15) = w²

  d) w = 5

  e) 5 by 5

Step-by-step explanation:

a) If w is the width, and the length is 15 less than 4 times the width, then the length is 4w-15. The area is the product of length and width.

  A = w(4w -15)

__

b) If w is the side length, the area of the square is (also) the product of length and width:

  A = w²

__

c) Equating the expressions for area, we have ...

  w(4w -15) = w²

__

d) we can subtract the right side to get ...

  4w² -15w -w² = 0

  3w(w -5) = 0

This has solutions w=0 and w=5. Only the positive solution is sensible in this problem.

The side length of the square is 5 units.

__

e) The rectangle is 5 units wide, and 4(5)-15 = 5 units long.

The rectangle and square have the same width and the same area, so the rectangle must be a square.

Answer:

C. 1/3x + 2y = -2

Step-by-step explanation:

Using the point slope form of an equation

y-y0 = m(x-x0)

Get the slope m

Get the x and y intercept of the equation

Using the expression  1/3x + 2y = -2

x intercept occurs at y = 0

1/3x + 0 = 2

1/3 x = 2

x = 3 * 2

x = 6

y intercept occurs at x = 0

0+ 2y = 2

2y = -2

y = -1

Hence the required equation is C. 1/3x + 2y = -2

Answer: distance is 5.4

Step-by-step explanation: distance between points (X1,y1) and (x2,y2) is

√(x2-X1)² + (y2-y1)² = √[(-4-(-6))² + (7-2)²] = √(2²+ 5²) =√29

The distance between the points (-6, 2) and (-4, 7) is 5.4 units.

The distance between any two points (x₁, y₁) and (x₂, y₂) can be determined using the distance formula according to which,

Distance = √((x₂ - x₁)² + (y₂ - y₁)²).

We are asked to find the distance between the points (-6, 2) and (-4, 7).

We will determine the distance using the distance formula, by which

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

or, Distance = √(((-4) - (-6))² + (7 - 2)²)

or, Distance = √((-4 + 6)² + (7 - 2)²) = √(2² + 5²) = √(4 + 25) = √29

∴ Distance = √29 = 5.385165 = 5.4 (rounding to the nearest tenth).

∴ The distance between the points (-6, 2) and (-4, 7) is 5.4 units.
