Answer:
The answer to the question is A
Answer:
X=7 and y=6
Step-by-step explanation:
Y=-2x + 20.......eq(i)
6x-5y=12.....eq(ii)
Now, putting y= - 2x +20 in eq (ii)
6x - 5(-2x + 20)=12
6x + 10x - 100 = 12
16x=12+100
X=112 /16
X=7
Then, putting x=7 in eq (i)
Y=-2*7 +20
=-14 +20
=6
Answer:
4y² + 5y - 3
roots are: (-5 ±
) / 8
Step-by-step explanation:
8y + 4y² - 3y - 3
4y² + 5y - 3
roots are: (-5 ±
) / 8
Using the Central Limit Theorem, the shape of the frequency curve will be approximately normal.
<h3>What does the Central Limit Theorem state?</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
.
Hence, the shape of the frequency curve will be approximately normal.
