6)The experimental probability is 39%.(39/100(100)).

7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.

The theoretical probability should be 33%.
The experimental probability is actually 39%.

Orange ribbon 2 meters long. The blue ribbon was 4/5 as long ad the orange. Linda cuts off a piece of blue ribbon. The length of

masha68 [24]

The initial length of the blue ribbon = 1.6 meters

Step-by-step explanation:

Here, according to the question:

The initial length of orange ribbon = 2 meters

Let us assume the initial length of blue ribbon = S meters

Now, the length of blue ribbon = (4/5) times the length of orange ribbon

$\implies S =( \frac{4}{5})$ x Length of Orange ribbon

$\implies S = (\frac{4}{5}) \times 2 = 1.6$

or S = 1.6 meters

Hence, the initial length of the blue ribbon is 1.6 meters.

This diagram is a straightedge and compass construction. A is the center of one circle, and B

Serhud [2]

Answer:

Correct choices are a, b, e

Step-by-step explanation:

As per diagram, the circles are equal.

<u>Since the distance AB is the radius of both circles:</u>

AB = AC = BC = BD = AD = r

<u>So the answer choices:</u>

a. AC = BC

Correct, both equal to r

b. AC = BD

Correct, both equal to r

C. CD = AB

Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3

d. ABCD is a square

Incorrect. ACBD is rhombus

e. ABD is an equilateral triangle

Correct, all three sides are equal to r

f. CD = AB + AB

Incorrect as CD = AB√3

Match the one-to-one functions with their inverse functions.

Nady [450]

The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function
$f(x)= \frac{x}{8} -7$
the inverse of the function is obtained as follows:
$y= \frac{x}{8} -7 \\ \\ y+7=\frac{x}{8} \\ \\ x=8(y+7) \\ \\ \bold{f^{-1}(x)=8(x+7)}$

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:
$y=x+7 \\ \\ x=y-7 \\ \\ \bold{f^{-1}(x)=x-7}$

Given the function
$f(x)=1- \frac{x}{3}$
the inverse of the function is obtained as follows:
$y=1- \frac{x}{3} \\ \\ -\frac{x}{3} =y-1 \\ \\ x=-3(y-1) \\ \\ \bold{f^{-1}(x)=-3(x-1)}$

Given the function
$f(x)=20-0.25x$
the inverse of the function is obtained as follows:
$y=20-0.25x=20- \frac{1}{4} x \\ \\ \frac{1}{4} x=20-y \\ \\ x=4(20-y) \\ \\ \bold{f^{-1}(x)=4(20-x)}$

sesenic [268]

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?

Parallel, slope is the same, perpendicular slope is opposite and reciprocal

line n, with slope −6 , same slope -----> Parallel

line p, with slope 1/6 , opposite and reciprocal -----> Perpendicular

line q, with slope −1/6 , -----> Neither

line m, with slope 6, -----> Neither
