- We have a bag with 4 white chips and 6 black chips
- Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?
4 white and 6 black
4 + 6 = 10
Choosing the first white chip :
Since we took one out , now
3 white chips , 6 black chips
3 + 6 = 9
Choosing another white chip :

2/21 is the answer.
1/3+4/7=19/21
Hope this helps!
The zeros for this function are -2, -1 and a double root of 0.
You can find this by first factoring the polynomial on the inside of the parenthesis. Polynomials like this can be factored by looking for two numbers that multiply to the constant (2) and add up to the second coefficient (3). The numbers 2 and 1 satisfy both of those needs and thus can be used as the numbers in a factoring.
x^2(x^2 + 3x + 2)
x^2(x + 2)(x + 1)
Now to find the zeros, we set each part equal to 0. You may want to split the x^2 into two separate x's for this purpose.
(x)(x)(x + 2)(x + 1)
x = 0
x = 0
x + 2 = 0
x = -2
x + 1 = 0
x = -1
Answer:
h=7.65
Step-by-step explanation:
h=k√p
k=h/√p
k=5.4/√1.44
k=4.5
h=4.5√p
when p=2.89
h=4.5√2.89
h=7.65
X= -1 I believe is the correct answer. Correct me if I messed something up
