Answer:

1. X=86

2. X=20

5. X=80.85

yan lang alam ko sorry

Step-by-step explanation:

1. z = 3, σ = 12, µ = 50

X=(3)(12) + (50)

  = 36+50

     X=86

2.  z = -2.5, σ = 12, µ = 50

X=(-2.5)(12) + (50)

  = -30 + 50

     X=20

5. z = -0.45, σ = 7, µ = 84

X=(-0.45)(7) + (84)

  = -3.15 + 84

     X=80.85

Answer:

1. z = 2

2. y = 9.2

3. y = 9

4. r = 9.2

5.?

Step-by-step explanation:

1. z = kx/y             z = kx/y    

  9 = k(6)/2          z = (3)(8)/12    

  18/6 = k(6)/6     z = 24/12    

  3 = k                  z = 2

2. y = kx/z                y = kx/z    

   23 = k(10)/2          y = (4.6)(18)/9  

   46/10 = k(10)/10    y = 82.8/9    

   4.6 = k                   y = 9.2

3. y = kx/z                         y = kx/z    

   12 = k(100)/25               y = (3)(36)/12

   300/100 = k(100)/100   y = 108/12  

   3 = k                              y = 9

4.  r = ks/u                r = ks/u      

    2 = k(18)/2           r = (0.22)(27)/ 3  

    4/18 = k(18)/18     r = 5.94/3

    0.22 = k               r = 1.98

Answer:

1)

A. [tex]r=\frac{4}{3}[/tex]B. [tex]s=36[/tex]C. [tex]u=4[/tex]

2) [tex]x=108\\[/tex]

3) [tex]w=\frac{1600}{3}[/tex]

Step-by-step explanation:

Variation, in mathematics, is the relationship between two or more variables. One is constant and the other one is changing. The process of changing variables is called variation.

Two Types of Variation

1. Varies Directly

2. Varies Inversely

Varies directly is the relationship between two variables when both of them go in the same direction. For example, one variable is increasing, the other one should also be increasing.

Varies inversely or indirectly is the relationship between two variables when they don't tend in the same direction. For example, one variable goes increasing and the other one goes decreasing.

Definition 1: We say that [tex]y[/tex] varies directly with [tex]x[/tex], then there exist a [tex]k[/tex] such that [tex]y=kx[/tex].

Definition 2: We say that [tex]y[/tex] varies inversely with [tex]x[/tex], then there exists a [tex]k[/tex] such that [tex]y=\frac{k}{x}[/tex].

For number 1, since [tex]r[/tex] varies directly as [tex]s[/tex] and inversely as the square of [tex]u[/tex], then the mathematical representation is [tex]r=\frac{ks}{u^2}[/tex]. Substitute the values of [tex]u=2[/tex], [tex]r=2[/tex], and [tex]s=18[/tex] into the model and solve for [tex]k[/tex].

                                     [tex]\begin{aligned}r&=\frac{ks}{u^2}\\2&=\frac{k(18)}{2^2}\\2&=\frac{18k}{4}\\4\left(2\right)&=4\left(\frac{18k}{4}\right)\\8&=18k\\\frac{8}{18}&=\frac{18k}{18}\\\frac{8}{18}&=k\\\frac{4}{9}&=k\end{aligned}[/tex]

A. Find [tex]r[/tex], when [tex]u=3[/tex] and [tex]s=27[/tex].

                    [tex]\begin{aligned}r&=\frac{ks}{u^2}\\r&=\frac{\frac{4}{9}(27)}{3^2}\\r&=\frac{4(3)}{9}\\r&=\frac{12}{9}\\r&=\frac{4}{3}\end{aligned}[/tex]

B. Find [tex]s[/tex], when [tex]u=2[/tex] and [tex]r=4[/tex].  

                    [tex]\begin{aligned}r&=\frac{ks}{u^2}\\4&=\frac{\frac{4}{9}s}{2^2}\\4&=\frac{\frac{4}{9}s}{4}\\4(4)&=4\left(\frac{\frac{4}{9}s}{4}\right)\\16&=\frac{4}{9}s\\\frac{9}{4}(16)&=\frac{9}{4}\left(\frac{4}{9}s\right)\\9(4)&=s\\36&=s\end{aligned}[/tex]

C. Find [tex]u[/tex], when [tex]r=1[/tex] and [tex]s=36\\[/tex].

                        [tex]\begin{aligned}r&=\frac{ks}{u^2}\\1&=\frac{\frac{4}{9}(36)}{u^2}\\1&=\frac{4(4)}{u^2}\\1&=\frac{16}{u^2}\\u^2(1)&=u^2\left(\frac{16}{u^2}\right)\\u^2&=16\\\sqrt{u^2}&=\sqrt{16}\\u&=4\end{aligned}[/tex]

For number 2, since [tex]x[/tex] varies directly as [tex]y^2[/tex] and inversely as [tex]z[/tex], then the mathematical representation is [tex]x=\frac{ky^2}{z}[/tex]. Substitute the values of [tex]x=12[/tex], [tex]y=3[/tex], and [tex]z=6[/tex] into the model and solve for [tex]k[/tex].

                                  [tex]\begin{aligned}x&=\frac{ky^2}{z}\\12&=\frac{k(3^2)}{6}\\12&=\frac{9k}{6}\\12(6)&=6\left(\frac{9k}{6}\right)\\72&=9k\\\frac{72}{9}&=\frac{9k}{9}\\8&=k\end{aligned}[/tex]

Find [tex]x[/tex], when [tex]y=9[/tex] and [tex]z=6[/tex].

                                   [tex]\begin{aligned}x&=\frac{ky^2}{z}\\x&=\frac{8(9^2)}{6}\\x&=\frac{648}{6}\\x&=108\end{aligned}[/tex]

                                     

For number 3, since [tex]w[/tex] varies directly as [tex]x[/tex] and [tex]y[/tex], and varies inversely as [tex]v^2[/tex] then the mathematical representation is [tex]w=\frac{kxy}{v^2}[/tex]. Substitute the values of [tex]x=4[/tex], [tex]w=1200[/tex], [tex]y=9[/tex], and [tex]v=6[/tex] into the model and solve for [tex]k[/tex].

                             [tex]\begin{aligned}w&=\frac{kxy}{v^2}\\1200&=\frac{k(4)(9)}{6^2}\\1200&=\frac{36k}{36}\\1200&=k\end{aligned}[/tex]

Find [tex]w[/tex], when [tex]x=3[/tex], [tex]y=12[/tex], and [tex]v=9[/tex].

                               [tex]\begin{aligned}w&=\frac{kxy}{v^2}\\w&=\frac{1200(3)(12)}{9^2}\\w&=\frac{43,200}{81}\\w&=\frac{1600}{3}\end{aligned}[/tex]

Step-by-step explanation:

y = 6x

v = 3s^2

a = (8/9) * (1/x)

y = 2xyz

z = 15xy

ito yung sa 4.

If y varies jointly with x and z, and y=12 when x=5 and z=2, then the constant of proportionality is 2. The equation that relates y, x, and z is y = 2xyz. This means that the value of y is directly proportional to the product of x and z. If the value of x or z changes, the value of y will also change in proportion to the change in x or z. For example, if x increases to 10 and z remains the same at 2, then y will increase to 2102 = 40. On the other hand, if x decreases to 3 and z remains the same at 2, then y will decrease to 232 = 12. Similarly, if x remains the same at 5 and z increases to 3, then y will increase to 253 = 30. If x remains the same at 5 and z decreases to 1, then y will decrease to 251 = 10.

27. 1. if y varies jointly as x and z and y=64, x=8 and z=2, find the constant of variation2. if a varies jointly as b and c, and a=36, when b=3 and c=4, find a when b=5 and c=63. if z varies directly as x and inversely as y, and z=9 when x=6 and y=2, find z when x=8 and y=124. if (r) varies jointly as (s) and inversely as the square of (v), and r=2 when s=8 and v=2 find r when s=27 and v=35. if y varies jointly as x and z, then y=24 when x=3 and z=4. find y when x=6 and z=8​

Answer:

k = constant of variation

1. k = 4

2. a = 90

3. z = 2

4. r = 3

5. y = 96

Step-by-step explanation:

1. y = kxz

64 = k(8)(2)

64 = 16k

k = 4

2. a = kbc

36 = k(4)(3)

36 = 12k

k = 3

We can now find a when b = 5 and c = 6

a =3(5)(6)

a = 90

3.

z = kx/y

9 =k(6)/2

9 = 3k

k = 3

z = 3(8)/12

z = 24/12

z = 2

4. r = ks/v^2

2 = 8k/2^2

2 = 8k/4

2 = 2k

k = 1

r = 27(1)/3^2

r = 27/9

r = 3

5. y = kxz

24 = k(4)(3)

24 = 12k

k =2

We can now find y when x = 6 and z = 8

y = 2(6)(8)

y = 96

28. 1. if p varies directly as s and inversely as t and p=8 when t=6 and s= 12, find pwhen s= 9 and t= 12.2.if d varies directly as n and inversely as m, and d=5 when m=6 and n=10, find d when n=12 and m=9.3.if z varies directly as x and inversely as y and z=12 when x=18 and y=6, find z when x=15 and y=10.(with solution pl.s)​

1. p=3

2. d=4

3. z=6

Hope you understand my solutions. Correct me if i'm wrong. ^_^
