Answer: The required lifetime value is 11.27.
Step-by-step explanation:
Since we have given that
Mean value = 11 hours
Standard deviation = 1 hour
The total lifetime of all batteries in a package exceeds that value for only 5% of all packages.
So, α = 0.95, z= 1.645
n = 9
So, the lifetime value would be
Hence, the required lifetime value is 11.27.
Answer:
The polynomial is a quadratic binomial
Step-by-step explanation:
we have
Classify the polynomial
<u>By the number of terms</u>
we know that
A polynomial with two terms is a binomial
<u>By the Degree of a Polynomial</u>
we know that
The degree of a polynomial is calculated by finding the largest exponent in the polynomial
In the given problem the largest exponent is
so
Is a quadratic equation
therefore
The polynomial is a quadratic binomial
<h3>hello!</h3>
Let's write this verbal phrase as an inequality.
First of all, let the number be n.
"three times n" can be written like so:-
Now, 18 is greater than 3n:-
Which means 3n is less than 18:-

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
Answer:
-1723
Step-by-step explanation:
Evaluate 5 - t^3 where t = 12:
5 - t^3 = 5 - 12^3
12^3 = 12×12^2:
5 - 12×12^2
