The results of the 100 rolls with the number cube are such that the probability of rolling a 2 is 32%.

<h3>What is the probability of rolling a 2?</h3>

This refers to the chances that the number cube rolls a 2 when thrown.

This can be found by the formula:

= Number of times 2 was rolled / Total number of times number cube was rolled

Solving gives:
= 32 / 100

= 32%

Answer:

8 x = 60.10251159

9 x = 3.66062978

Step-by-step explanation:

Hey There!

So to answer these questions we need to use the Law of sines

Consider the following image

So to find x in number 8 we setup an equation

$\frac{x}{sin90} =\frac{48}{sin53}$

now we solve for x

step 1 multiply each side by sin 90

now we have

$x = \frac{48sin90}{sin53}$

if you plug the equation in a calculator you get that

x=60.10251159

( make sure if it says to round to the nearest.... that you round before entering your answer)

For number 9 the equation would be

$\frac{9}{sin90} =\frac{x}{sin24}$

now we solve for x

step 1 multiply each side by sin 24

now we have

$x=\frac{9sin24}{sin90}$

if you plug this into a calculator you get that

x = 3.66062978

(once again if it says to round to the nearest... make sure you round before you put in your answer.)

Answer:

1. Find the circumference, then multiply that by 120 turns.

Formula for circumference;

C = 2πr

But, we need to find the radius which is 1/2(half) of the diameter, so,

D/2 = R

D = Diameter

R = Radius

20/2 = 10 is the radius.

Plug in values now:-

C = 2(3.14) x 10

C = 6.28 x 10

C = 62.8 is the circumference, now we multiply this by 120 to get the total amount of centimetres it'll go.

62.8(120)

= 7,536 cm it'll go.

2. Find the circumference, then multiply that by 750 turns/revolutions.

C = 2πr

Find radius,

D/2 = R

50/2 = 25 is the radius.

Plug in values now:-

C = 2(3.14) x 25

C = 6.28 x 25

C = 157 cm it'll go.

3. Same thing, find circumference then compare values.

Given that radius is 10,

Use the formula for circumference;

C = 2πr

Replace values:-

C = 2(3.14) x 10

C = 6.28 x 10

C = 62.8 cm is the circumference of the first circle.

Now the second circle, (use same formula)

C = 2πr

Find radius,

D/2 = R

10/2 = 5 is the radius.

Replace values:-

C = 2(3.14) x 5

C = 6.28 x 5

C = 31.4 cm is the circumference for the second circle.

Now subtract the second circle's circumference from the first:

62.8 - 31.4

= 31.4, 31.4 cm is how much greater the second circle is than the first.

4 - 5. Find circumference, (using circumference formula)

C = 2πr

Find radius,

D/2 = R

760/2 = 380

Replace values:-

C = 2(3.14) x 380

C = 6.28 x 380

C = 2,386.4 km is the distance he'll travel.

If he wants to travel around it with 2,000 km, he'll need to travel at least once.
