Simon used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 time
morpeh [17]

Answer:

360/2500

Step-by-step explanation:

the blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

Find the measure of each exterior angle of a regular<br> 15-gon.
sammy [17]

The measure of each exterior angle of a regular 15-side polygon is

24°

Step-by-step explanation:

In any regular polygon

  • All sides are equal in lengths
  • All angles are equal in measures
  • The measure of each interior angle = \frac{(n-2)*180}{n} , where n is the number of its sides
  • The measure of each exterior angle = \frac{360}{n}
  • The interior angle and the exterior angle at any vertex are supplementary

∵ The polygon is regular

∵ It has 15 sides

∴ n = 15

∵ The measure of each exterior angle = \frac{360}{n}

∴ The measure of each exterior angle = \frac{360}{15}

∴ The measure of each exterior angle = 24°

The measure of each exterior angle of a regular 15-side polygon is

24°

PLZ ANSWER QUICKLY, WILL GIVE THE BRAINLIEST AND 25 POINTS!
valkas [14]

We are given that ratio of cars Sam has built to cars Tyrone has built is 3:4.

Let us assume that Sam built 3x cars and Tyrone built 4x.

Since we are given that total number of cars they built is 42. Therefore, we can set up:

3x+4x=42\\&#10;7x=42\\&#10;x=6

Therefore, Sam built 3x=3(6)=18 cars and Tyrone built 4x=4(6)=24 cars.
