Answer:
618
Step-by-step explanation:
half means you divide by 2.
so 1,236/2=618
hope this helps
Substitute the first y= equation into the y of the second. Distribute as needed and solve for x. x=2 and then plug it in to find y. y=7
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
If a = 6 -
, find the value of a² + 
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
a = 6 -
(Given)
Now, first of all we have to find the value of
.
So,
=
=
= 
=

= 
= 6 + 
Now, we have to find the value of a² +
So, a² +
=
- 2.a.
a² +
=
- 2
a² +
= (12)² - 2
a² +
= 144 - 2
a² +
= 142
The value of a² +
is <u>1</u><u>4</u><u>2</u>. [Answer]
Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
