Answer:
For 99% of confidence interval is 67.5±1.3524
Step-by-step explanation:
Given:
Mean height =67.5 inches
Standard deviation:2.1 inches
Z at 99%.
No of samples 16.
To find:
confidence interval
Solution:
We have formula for confidence interval,
=mean ±Z*{standard deviation/sqrt(no.of observation)}
Now
Z=99%
has standard value as ,
Z=2.576
Confidence interval= mean±Z{standard deviation/sqrt(No. of samples)}
=67.5±2.57{(2.1/sqrt(16)}
=67.5±2.576(2.1/4)
=67.5±1.3524
The slope is 0.1
To find a perpendicular slope, find the negative reciprocal.
The reciprocal of 0.1 is 10
The negative of 10 is -10
Final answer:-10
Answer:
<h2>f(4) = -4</h2>
Step-by-step explanation:
f(x) = 4x - 20
f(4) → put x = 4 to the equation of the function:
f(4) = 4(4) - 20 = 16 - 20 = -4
Answer:
5x + 1 is the simplest form
Step-by-step explanation:
what is equivalent to 10x - (5x -1)
10x - (5x -1) = 10x - 5x + 1
= 5x + 1
