Answer:
26 pints
Step-by-step explanation:
1 quart = 2 pints
13*2=26
So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
I think you are asking for two numbers, so you just have to look at the decimals.
23.7
We can use an infinite amount of numbers here, but to make it simple you can just take away 0.01 or add 0.01.
23.69
23.71
These are funny answers as well because they both round to 23.7 and meet the requirements.
You need to add the two quadratics together...
x^2+11x-6+6x^2-3x+9
7x^2+8x+3
Answer:
1/4
Step-by-step explanation:
Let's denote the probabilities as following:
Probability that a teenager has a sister:
P(A) = 12/28
Probability that a teenager has a brother:
P(B) = 7/28
Probability that a teenager has both a sister and a brother:
P(A⋂B) = 3/28
Probability that a selected teenager has a sister also has a brother, or in other words, he/she has a brother, given he/she had a sister:
P(B|A)
Let's apply the formula of conditional probability to work out P(B|A)
P(B|A) = P(A⋂B)/P(A) = (3/28)/(12/28) = (3*28)/(12*28) = 3/12 = 1/4
=> Option C is correct
Hope this helps!
