Answer:
P(Multiple of 3) = 33/100
Step-by-step explanation:
We have 3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100 total rolls
We have 6 + 14 + 12 + 1 = 33 rolls of a multiple of 3
P(Multiple of 3) = 33/100
B.
There are no black pieces of paper in her closet so it’s impossible to get black
Just multiply x times x and y times y
Answer:
The ratio of sides of triangle = 13:14:15
perimeter = 84 CM
perimeter of a triangle = Sum of all sides
let the sides of a triangle be 13x, 14x and 15x
84 = 13x + 14x + 15x
84 = 42x
x = 2
13x = 13* 2 = 26 CM
14x = 14*2 = 28 CM
15x = 15*2 = 30 CM
Answer:
Raising something to a negative exponent is just taking the reciprocal of the amount.
Step-by-step explanation:
Let's assume that you wanted to know what is.
To find it, you would take the reciprocal of the x amount. So becomes .
This works because of the nature of exponents. Exponents represent the number of times you are multiplying a value by itself. So would be equal to a · a · a. To increase the exponent, you increase the number of times the value is multiplied by itself: To increase to , you would have to multiply a with two more times (a · a · a · a · a). To decrease the exponent, you must divide the value by itself. So to decrease to , you would have to divide by a 3 times.
If the exponent is 0, the value is equal to 1. But you can still decrease the exponent into negative numbers. You just divide 1 by a the desired amount of times: means that you are dividing 1 by a 3 times.
Hope this helps.
