The figure depicting the board game is attached below.
Answer:
Step-by-step explanation:
Kindly note that selections done without replacement.
Count of numbers on the board game = 8
Count of odd numbers = (1, 9, 1) = 3
Count of digit 6 = 3
Probability = required outcome / Total possible outcomes
P(picking an odd number) = 3 / 8
Without replacement
Numbers left on board game = 8 - 1 = 7
P(picking a 6) = 3 / 7
Hence,
P(picking an odd number then, a 6) = 3/8 * 3/7 = 9 / 56
Answer:
32
Step-by-step explanation:
let the number be n , then
n + 
n = 12 ( multiply through by 8 to clear the fractions )
2n + n = 96
3n = 96 ( divide both sides by 3 )
n = 32
The number is 32
Answer:
Step-by-step explanation:
The zeros of the function can be found by factoring. Since this has already been started with completing the square, we will just pick up from where it was left and finish factoring. Set the quadratic equal to 0 first.
then move over the 9:
"undo" the squaring by square rooting both sides to get
x - 8 = ±3. And then add over the 8 to get the solutions
x = 8 + 3 and x = 8 - 3. The solutions, then, are
x = 5 and x = 11
Answer:
8
Step-by-step explanation:
x = centesimal angle (100 degrees in a right angle)
y = sexagesimal angle (90 degrees in a right angle)
x - y = 15
x×90/100 = y
x×9/10 = y
x - x×9/10 = 15
10x/10 - 9x/10 = 15
x/10 = 15
x = 150
y = 150×9/10 = 15×9 = 135
using centesimal system :
the sum of all external angles in a polygon is 400 degrees (a full circle).
one external angle is the complement of one internal angle to 200 degrees = 200-150=50 degrees.
to find the number of sides of the polygon we need to find the number of angles or corners. and that is how many external angles fit into the full circle.
n = 400/50 = 8
the polygon has 8 sides
The three subtraction sentences 12-4=8, 8-4=4, and 4-4=0 can be expressed as a single division sentence. The division sentence 12/4 = 3 means that, starting with the number 12, 4 can be subtracted 3 times to get zero.
Division is repeated subtraction 12 / 4 means how many 4's you can subtract from 12. 12 orange split into units of 4, then how many kids can get 4 oranges 12 - 4 = 8 1st kid 8 -4 = 4 2nd kid 4 - 4 = 0 3rd kid So 3 kid can get 4 oranges each. If we multiply 3 * 4 =12 if each 3 kids get each 4 oranges , then what was the total oranges distributed among kids Now we say that Multiplication is repeated addition. 4 * 3 = 12, 4 + 4 + 4 = 12 Further we can say that Multiplication and division is opposite of each other Like 2 * 3 = 6 6/3 = 2 6/ 2 =3 , Also division and fractions are the same, and symbols can be used interchangeably.
