Step-by-step explanation:
Answer:
9 red tiles
Step-by-step explanation:
Total number of tiles: 
Total number of red tiles: 
Probability of getting red in one draw: 
<em>This means that you would expect to get red 
or 30% of the times.</em>
<em>Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:</em>
<em>
</em>
So, you would expect to draw a red tile from the bag 9 times.
Total number of campers = 20
Total number of teams = 5
⇒ Number of campers in each team = Total number of campers ÷ Total number of teams
⇒ Number of campers in each team = 20 ÷ 5
⇒ Number of campers in each team = 4
Number of recorders in each team = 1
⇒ Number of searchers in each team = Number of campers in each team - Number of recorders in each team
⇒ Number of searchers in each team = 4 - 1
⇒ Number of searchers in each team = 3
Hence, there will be 3 searchers in each team
The value of x is 36.
Solution:
Given angles of a triangle are 2x°, 2x° and x°.
To find the value of x:
<em>Sum of the all the angles of a triangle = 180°</em>
2x° + 2x° + x° = 180°
5x° = 180°
Divide by 5 on both sides of the equation.
x° = 36°
x = 36
The value of x is 36.
The correct answer is x=1
