(2x² + 5x -3)(3x + 7)
=(6x³ +14x²+15x² +35x - 9x -21)
=6x³ +29x² + 26x -21
AND SO...
the answer is D.
Answer:
its a i think
Step-by-step explanation:
Answer:
y = 3x +6
Step-by-step explanation:
6x-2y=-12
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 6x from each side
6x-6x-2y=-6x-12
-2y = -6x-12
Divide each side by -2
-2y/-2 = -6x/-2 -12/-2
y = 3x +6
Using the Central Limit Theorem, it is found that the standard deviation is of 0.0971.
<h3>What does the Central Limit Theorem states?</h3>
- It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean
and standard deviation
, as long as
and
.
- It also states that when two variables are subtracted, the standard deviation is the square root of the sum of the variances.
In this problem, for each sample, the standard error is given by:


Hence, for the distribution of differences, it is given by:

1/5 of 55 is 11, you multiply 11 by 20 and you get 220. Total there is 1100 minutes of tv so then you subtract 220 from 1100 and there is 880 minutes of tv without commercials then you divide that by 60 and you get 14 hours and 20 minutes.
