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.
Reflection, the quadratic parent function is reflected on the opposite side
For numbers 9 and 10, we are dealing with negative exponents.
The rule of exponents states that any quantity b, taken to the power -n, equals the reciprocal of b, taken to the nth power.
Example: x⁻³ = 1 / x³
Number 9: ( 3 / y² ) ⁻³
Step 1: take the reciprocal:
( 3 / y² ) ⁻³ = ( y² / 3 ) ³
Step 2: distribute the exponent
( y² / 3 ) ³ = y⁶ / 27
Try to do number 10 on your own. If you have any questions, comment.
C is the median.
to find the median we need to put all the numbers given in order from smaller to largest
12, 18, 34, 55, 59, 67, 80, 80
then find the middle number of these
well we have to middle numbers 59 and 55
so we need to find the mid number between these two which 57.
The answer to this question is 57
