Answer:

6:7

12:14

24:28

Step-by-step explanation:

The beginner ratio is 6:7 to find new equal ratios we just multiply both numbers by a number. In those, each of them is multiplied by two. You can multiply it by any number as long as you keep the 6's answer in the 6's spot and same for 7 & that you multiply both sides and not just one.

Answer:

The formula for the point biserial correlation coefficient is:

point biserial correlation formula

M1 = mean (for the entire test) of the group that received the positive binary variable (i.e. the “1”).

M0 = mean (for the entire test) of the group that received the negative binary variable (i.e. the “0”).

Sn = standard deviation for the entire test.

p = Proportion of cases in the “0” group.

q = Proportion of cases in the “1” group.

Most people won’t work this formula by hand as most statistical software packages can calculate the coefficient for you.

Let the number be n.

Now, "seven less than a number" means we subtract 7:-

n-7

This expression is equal to 18:-

Answer:

There denominators are same, ie = 12

Step-by-step explanation:

Sum , 1 + 5/12 = (12 + 5) / 12

= 17 / 12  

Sum , 2/3 + 3/4 = (8 + 9) / 12

= 17 / 12

Answer:

100% increase

Step-by-step explanation:

Answer:

Angle 1: 135*

Angle 2: 45*

Angle 3: 45*

Angle 4: 135*

Angle 5: 135*

Angle 6: 45*

Angle 7: 45*

Angle 8: 135*

Step-by-step explanation:

So we have angle 2, 45*, we can subtract 45 from 180 to get the angle for 1. Since everything is the same size as either 1 or 2 we can just plug in the bigger angle number we have for it, ex 4= 135 and so is 7.

If you don't understand something please don't hesitate to ask.

Answer:

Step-by-step explanation:

∠2 = 45

∠3 = ∠2    {Vertically opposite angles}

∠3 = 45

∠7 = ∠3    {Corresponding angles}

∠7 = ∠45

∠6 = ∠7        {Vertically opposite angles}

∠6 = 45

∠1 + ∠2 = 180   {Linear pair}

∠1 + 45 = 180

∠1  = 180 -45

∠1 = 135

∠4 =∠1  {Vertically opposite angles}

∠4 = 135

∠8 = ∠4  {Corresponding angles}

∠8 = 145

∠5 = ∠4         {Alternate interior angles}

∠5 = 145

Answer:

10 7/40

Step-by-step explanation:

5 4/5 + 4 3/8

4/5 = 32/40

3/8 = 15/40

5 32/40 + 4 15/40 = 9 47/40 = 9 + 1 7/40 = 10 7/40

Answer:

30.96 m^2

Step-by-step explanation:

Side length of the square is also the diameter of the semicircle so:

r = 0.5 * 12 m = 6 m

Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:

Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area

(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)

= 144 - 56.52 - 56.52

= 30.96 m^2

Answer:

When y = 4, x is equal to 39

Step-by-step explanation:

The given parameters are;

x = a + b + 4

a ∝ 1/y²

b ∝ 1/(1/y) = y

When y = 2, x = 18

When y = 1, x = -3

Therefore, we have;

a·y² = j

a = j/y²

b ∝ 1/(1/y)

∴ b ∝ y

b = k·y

When y = 2, x = 18, we have;

a = j/y² = j/2² = j/4

b = k·y = k·2

x = a + b + 4

∴ 18 = j/4 + k·2 + 4...(1)

When y = 1, x = -3, we have;

a = j/y² = j/1² = j

b = k·y = k·1 = k

x = a + b + 4

∴ -3 = j + k + 4...(2)

Making 'j', the subject of equation (1) and (2) gives;

From equation (1), we have;

18 = j/4 + k·2 + 4

∴ j = (18 - 4 - k·2) × 4 = 56 - 8·k

From equation (2), we have;

-3 = j + k + 4

∴ j = -3 - 4 - k = -7 - k

Equating the two values of 'j', gives;

56 - 8·k = -7 - k

56 + 7 = 8·k - k

63 = 7·k

k = 63/7 = 9

k = 9

From equation (2), we get;

-3 = j + k + 4

k = 9

∴ -3 = j + 9 + 4

j = -3 - 9 - 4 = -16

j = -16

When y = 4, we get;

x = a + b + 4

a = j/y²

b = k·y

∴ x = j/y² + k·y + 4

Plugging in the values of 'j', and 'k' and y = 4, gives;

x = (-16)/y² + 9·y + 4

∴ x = (-16)/4² + 9 × 4 + 4 = 39

x = 39

Therefore;

When y = 4, x = 39.
