Answer:
sinx
Step-by-step explanation:
hello :
note :
for all x in ℝ : 1) sin(x+2π) = sinx 2) sin(π-x) = sinx
in this exercice :
3π - x = 2π+(π - x)
sin(3π - x) = sin(2π +(π - x)) =sin(π-x) = sinx
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
Mode (most occurring) - 4
mean (average) - 8
median (middle number from least to greatest) - 4
The answer to this question is 5/6
Answer:
9.) The slope is 3 and the y-intercept is -5
10.) y = 0.25x -11
Hope this helped!
