Answer:
x^2 -6x +6
Step-by-step explanation:
<em>Square of a difference (can be found in IM2)</em>
Formula: a^2 -2ab +b^2
x= a; 3= b
(x -3)(x -3)
<em>Plug in to formula.</em>
x^2 -2(x)(3) +3^2
<em>Simplify.</em>
x^2 -6x +6
Answer:
The margin of error of his experiment is of 0.1074.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of
.
The margin of error is of:

30 M & M's from a bag, and 3 of them are green.
This means that 
Standard 95% confidence level
So
, z is the value of Z that has a p-value of
, so
.
Margin of error:



The margin of error of his experiment is of 0.1074.
1. -4 times 3 and 21
2.add -12 and -84
3.-96 dived by 2
4 equals -48
Answer:
28 cubs
Step-by-step explanation:
Since one and a half bear produces one and a half cub, then 6 bears will produce 6 cubs in one and a half days.
We need to find 7 days, though but we have the rate for six bears for 1.5 days which 6 bears one a half day.
What is the rate for a day?
6/1.5 =
6 bears produce 4 cubs a day.
Now just do 4 x 7
4 x 7 = 28
Therefore, 6 bears produce 28 cubs in 7 days.
