Answer:
All events are independent
Step-by-step explanation:
You are given the table
Two events A and B are independent when
a) A="Chocolate"
B="Adults"
A and B="Chocolate and Adults"
Since 
events are independent
b) A="Children"
B="Chocolate"
A and B="Children and Chocolate"
Since 
events are independent
c) A="Vanilla"
B="Children"
A and B="Vanilla and Children"
Since 
events are independent
So this is going to be using proportions, which in this case is going to be 
Firstly, cross-multiply to get 
Next, just divide 18 on both sides, and your answer will be 
, or the last option.
Answer:
x = -4.59, -7.41.
Step-by-step explanation:
x^2 + 12x + 34 = 0
(x + 6)^2 - 36 +34 = 0
(x + 6)^2 = 36 - 34 = 2
x + 6 = +/-√2
x = +/-√2 - 6
x = -4.59, -7.41
Answer: m=vD
Step-by-step explanation:
To get m alone, you want to use algebraic properties.
[multiply both sides by v]
Now that we have mass alone, we know that m=vD.
Estimation is about rounding answers to the nearest whole or to a simple fraction.
11.6 is closer to 12 than it is to 11 so we can estimate that
11.6≈12
And .25 is closer to 0 than it is to .5 so we can estimate
.25≈0
It also depends what place we are rounding to, we can say that .25 is close to .3 because we don't want to have a 0 value
.25≈.3
