Answer:
Step-by-step explanation 1 and 4
Answer:
0.028
Step-by-step explanation:
Let sample space, S, be the trucks.
Hence, n(S)= number of trucks=9750
Let E be the event of the truck failing within the first two years of operation.
Hence, n(E)=273
Therefore by classical definition of probability, the probability of occurrence of the event E, denoted by P(E), is
P(E)=
=
⇒P(E)=
=0.028
<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]
