For the given experiment, the relative frequency of getting tails is:

R = (12/25)*100% =48%

<h3>How to get the relative frequency?</h3>

If we perform an experiment N times, and out of these N times, K times we get a given outcome (Where K is a number equal to or smaller than N).

The relative frequency of that particular outcome is given by the quotient between the number of times that we got that outcome and the total number of times that the experiment was performed.

In this case, the experiment is performed 25 times, and 12 times we get tails, then the relative frequency for getting tails is:

R = 12/25

If we want to write it in percentage form, then we get:

R = (12/25)*100% =48%

If a angle is 4 times bigger than its supplement what will its measure be
Ne4ueva [31]
Supplementary angles mean that two angles equal to 180°.

Let us assume the 2 angles are angle A and angle B.

Angle A is 4 times bigger than Angle B, the supplement.

Let Angle B be represented by x.

Angle A is 4x ; Angle B is x.

4x + x = 180°
5x = 180°
x = 180°/5
x = 36°  This is the measure of angle B.

4x = 4(36°) = 144° This is the measure of angle A.

4x + x = 180°
144° + 36° = 180°
180° = 180°

The equation y = 1725 - 75x represents the amount of money y (in dollars) left in your lunch account after x weeks. 20 weeks go
garik1379 [7]
Y= -75x +1725
y= -75(20) +1725
y = -1500 + 1725
y= 225 = range
225= -75x +1725
225 - 1725= -75x
-1500=-75x
-1500/-75 = -75x/-75
x = 20 = domain

Hey puddin could ya help me !?- What is the length of segment AB?
ycow [4]

Answer:

AB = 4\sqrt{5}

Step-by-step explanation:

Calculate AB using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(0, 10)

AB = \sqrt{(0-6)^2+(10-2)^2}

     = \sqrt{4^2+8^2}

    = \sqrt{16+64}

    = \sqrt{80} = 4\sqrt{5} ← exact length
