What does experimental and theoretical probability mean?

1 answer:

5 0

Experimental Means new invention or product) based on untested ideas or techniques and not yet established or finalized. Theoretical Probability Means. is the likeliness of an event happening based on all the possible outcomes. The ratio for the probability of an event 'P' occurring is P (event) = number of favorable outcomes divided by number of possible outcomes.

I don’t understand pls help!!

Answer:

7.9 m

Step-by-step explanation:

Use the Pythagorean theorem: a²+b²=c²

This formula can be used to solve a side of any right (90°) triangle.

c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)

So, c = 32m.

Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:

31² + b² = 32²

961 + b² = 1024 Subtract 961 from both sides to get b² by itself.

b² = 63

√b² = √63 Square root both sides to get b by itself.

b = 7.93725

Answer is 7.9 meters, rounded to tenths place

A city planner designs a park that is a quadrilateral with vertices at J(−1, 1), K(1, 3), L(5, −1), and M(−3, −1). There is an e

Vadim26 [7]

use the eqn below to find the mid-pts

x-mid-pt = (x₁+x₂)/2

y-mid-pt = (y₁+y₂)/2

J(−1, 1), K(1, 3), L(5, −1), and M(−3, −1)

midpoint JK = (-1+1/2, 1+3/2) = (0,2)

midpoint KL = (1+5/2, 3+⁻1/2) = (3,1)

midpoint LM = (5+⁻3/2, ⁻1+⁻1/2) = (1,-1)

midpoint MJ = (⁻3+⁻1/2, -1+1/2) = (-2,0)

use the eqn to find distance:

d = √(x₂ - x₁)² + (y₂ - y₁)²

Distance between JK and LM = √(0⁻1)² + (2 - ⁻1)² = √1 + 9 = √10

Distance between JM and KL = √(3-⁻2)² + (1-0)² = √25 + 1 = √26

Scale is 10

Actual distance = 10*(√10 + √26) = 82.6 = 83 units

A quilt is designed using a square pattern. each square contains two rectangles. each rectangle contains a shaded rhombus. each

Xelga [282]

Based on the calculations, the value of x in this rhombus is equal to: B. 55.

<h3>How to determine the value of x?</h3>

Since the opposite angles in a rhombus are always congruent, the sum of each angle in any rhombus must be equal to 360 degrees.

From the image of the rhombus, we can deduce the following parameters:

Adjacent angles = 2x + 20 and 50 degrees.

Opposite angles = 2x + 20 and 50 degrees.

Adding the angles, we have:

2x + 20 + 2x + 20 + 50 + 50 = 360

4x + 140 = 360

4x = 360 - 140

4x = 220

x = 220/4

x = 55°
