Answer:

<h2>See below</h2>

Step-by-step explanation:

Theoretical probability is the actual chance of something happening based on raw numbers.

For example: The theoretical probability of tails on a coin flip is 1/2 or 50%. If you flipped a coin, you would expect 50% to be heads, 50% to be tails.

However, since this almost never happens, experimental probability is used to describe the actual results.

For example: If you flip the coin 50 times and 23 are tails, 27 are heads, then the experimental probability is 46% for tails and 54% for heads.

I'm always happy to help :)

Write an equation In slope intercept form for the line that is parallel to the given line and that passes through the given poin

ludmilkaskok [199]

The equation of the parallel line in slope-intercept form is;

y = $\frac{5}{2}$ x - $\frac{25}{2}$

Step-by-step explanation:

Let us revise some facts about parallel lines

The equations of two parallel lines have:

Same slopes
Different y-intercept

The slope-intercept form of the equation of a line is y = m x + b, where m is the slope of the line and b is the y-intercept

The given line has equation 5x - 2y = 10

Put it in the form of y = m x + b to find its slope

∵ 5x - 2y = 10

- Subtract 5x from both sides

∴ -2y = 10 - 5x

- Divide to sides by -2

∴ y = -5 + $\frac{5}{2}$ x

∴ y = $\frac{5}{2}$ x - 5

- The value of m is the coefficient of x

∴ m = $\frac{5}{2}$

∴ The slope of the given line is $\frac{5}{2}$

∵ Parallel lines have same slopes

∴ The slope of the parallel line is m = $\frac{5}{2}$

- Substitute the value of m in the form of the equation

∴ The equation of the parallel line is y = $\frac{5}{2}$ x + b

To find b substitute x and y in the equation by the coordinates of any point lies on the line

∵ The parallel line passes through point (3 , -5)

- Substitute x and y by the coordinates of the point (3 , -5)

∵ x = 3 and y = -5

∴ -5 = $\frac{5}{2}$ (3) + b

∴ -5 = $\frac{15}{2}$ + b

- Subtract $\frac{15}{2}$ from both sides

∴ b = $\frac{-25}{2}$

∴ The equation of the parallel line is y = $\frac{5}{2}$ x + $\frac{-25}{2}$

∴ The equation of the parallel line is y = $\frac{5}{2}$ x - $\frac{25}{2}$

The equation of the parallel line in slope-intercept form is;

y = $\frac{5}{2}$ x - $\frac{25}{2}$

9th grade ..Plz solve this maths

8_murik_8 [283]

since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°

so the angle WOP = 45°

now drawing a imaginary line which seperates the triangleWOP into half

so the angle of imaginary line is 45/2 = 22.5

sin(theta) = opp/hyp

since WP (opp) is unknown. take as x

sin(22.5) = x/44

0.383×4 = x

x = 1.532 (app) = 1.5 cm

perimeter = 1.5 × 8

= 12 cm

area of triangle WOP = 2×1/2 ×bh = bh

= 4×1.5

= 6 cm²

so the area of regular polygon = 8× area of a triangle

= 48 cm²
