Answer:
5/9
Step-by-step explanation:
Answer:
2/35
Step-by-step explanation:
Assuming that this is without replacement,
The total amount of marbles is 2+9+3+7, or 21.
9 are yellow, 3 are white. this makes 12.
The probability of selecting a white or yellow marble is 12/21.
Now without replacement (comment if it is with replacement.), there are 20 marbles left, and 2 are Cordovan. This means there is a 2/20 chance then of picking a Cordovan marble.
After multiplying the fractions we get
(12/21) * (2/20) = 2/35.
There is a 2/35 chance of selecting a yellow or white, then a cordovan marble.
Answer:
The answer is D.
Step-by-step explanation:
We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :
The answer is 54x so yeah
Answer:
We have a formula for division algorithm a= bq+r (1)
a is the greatest integer between the two given integers
And b is the other integer
q is the quotient
r is the remainder
here we have a=192 and b=7 substituting values in equation (1) we get
192 = 27 *7 + 3 (2)
now substitute quotient from equation (2) in place of a that is a=27 and remainder in place of b that is b =3 in equation as below
27= 9*3 +0
we will proceed till we get remainder zero.
