Answer:
y=0.5x+3
Step-by-step explanation:
So the point of this is to make y the only thing on one side. So first you have to add 6 on both sides. That would make is x+6=2y. Next you need to divide 2 on both sides. That would equal 0.5x+3=y.
Hope this helped!!! :D
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 quotient for the question is: -343
Answer:
7
Step-by-step explanation:
Answer:
38+31+43+x=180
Step 1: Simplify both sides of the equation.
38+31+43+x=180
(x)+(38+31+43)=180(Combine Like Terms)
x+112=180
Step 2: Subtract 112 from both sides.
x+112−112=180−112
x=68
